Class

GtkTreeView

Description [src]

class Gtk.TreeView : Gtk.Container {
  parent: GtkContainer
}

Widget that displays any object that implements the GtkTreeModel interface.

Please refer to the [tree widget conceptual overview][TreeWidget] for an overview of all the objects and data types related to the tree widget and how they work together.

Several different coordinate systems are exposed in the GtkTreeView API. These are:

Coordinate systems in GtkTreeView API:

  • Widget coordinates: Coordinates relative to the widget (usually widget->window).

  • Bin window coordinates: Coordinates relative to the window that GtkTreeView renders to.

  • Tree coordinates: Coordinates relative to the entire scrollable area of GtkTreeView. These coordinates start at (0, 0) for row 0 of the tree.

Several functions are available for converting between the different coordinate systems. The most common translations are between widget and bin window coordinates and between bin window and tree coordinates. For the former you can use gtk_tree_view_convert_widget_to_bin_window_coords() (and vice versa), for the latter gtk_tree_view_convert_bin_window_to_tree_coords() (and vice versa).

GtkTreeView as GtkBuildable

The GtkTreeView implementation of the GtkBuildable interface accepts GtkTreeViewColumn objects as <child> elements and exposes the internal GtkTreeSelection in UI definitions.

An example of a UI definition fragment with GtkTreeView:

<object class="GtkTreeView" id="treeview">
  <property name="model">liststore1</property>
  <child>
    <object class="GtkTreeViewColumn" id="test-column">
      <property name="title">Test</property>
      <child>
        <object class="GtkCellRendererText" id="test-renderer"/>
        <attributes>
          <attribute name="text">1</attribute>
        </attributes>
      </child>
    </object>
  </child>
  <child internal-child="selection">
    <object class="GtkTreeSelection" id="selection">
      <signal name="changed" handler="on_treeview_selection_changed"/>
    </object>
  </child>
</object>

CSS nodes

treeview.view
├── header
│   ├── <column header>
┊   ┊
│   ╰── <column header>
│
╰── [rubberband]

GtkTreeView has a main CSS node with name treeview and style class .view. It has a subnode with name header, which is the parent for all the column header widgets’ CSS nodes. For rubberband selection, a subnode with name rubberband is used.

Creates a new GtkTreeView widget.

gtk_tree_view_new_with_model

Creates a new GtkTreeView widget with the model initialized to model.

Instance methods

gtk_tree_view_append_column

Appends column to the list of columns. If tree_view has “fixed_height” mode enabled, then column must have its “sizing” property set to be GTK_TREE_VIEW_COLUMN_FIXED.

gtk_tree_view_collapse_all

Recursively collapses all visible, expanded nodes in tree_view.

gtk_tree_view_collapse_row

Collapses a row (hides its child rows, if they exist).

gtk_tree_view_columns_autosize

Resizes all columns to their optimal width. Only works after the treeview has been realized.

gtk_tree_view_convert_bin_window_to_tree_coords

Converts bin_window coordinates to coordinates for the tree (the full scrollable area of the tree).

Available since: 2.12

gtk_tree_view_convert_bin_window_to_widget_coords

Converts bin_window coordinates (see gtk_tree_view_get_bin_window()) to widget relative coordinates.

Available since: 2.12

gtk_tree_view_convert_tree_to_bin_window_coords

Converts tree coordinates (coordinates in full scrollable area of the tree) to bin_window coordinates.

Available since: 2.12

gtk_tree_view_convert_tree_to_widget_coords

Converts tree coordinates (coordinates in full scrollable area of the tree) to widget coordinates.

Available since: 2.12

gtk_tree_view_convert_widget_to_bin_window_coords

Converts widget coordinates to coordinates for the bin_window (see gtk_tree_view_get_bin_window()).

Available since: 2.12

gtk_tree_view_convert_widget_to_tree_coords

Converts widget coordinates to coordinates for the tree (the full scrollable area of the tree).

Available since: 2.12

gtk_tree_view_create_row_drag_icon

Creates a #cairo_surface_t representation of the row at path. This image is used for a drag icon.

gtk_tree_view_enable_model_drag_dest

Turns tree_view into a drop destination for automatic DND. Calling this method sets GtkTreeView:reorderable to FALSE.

gtk_tree_view_enable_model_drag_source

Turns tree_view into a drag source for automatic DND. Calling this method sets GtkTreeView:reorderable to FALSE.

gtk_tree_view_expand_all

Recursively expands all nodes in the tree_view.

gtk_tree_view_expand_row

Opens the row so its children are visible.

gtk_tree_view_expand_to_path

Expands the row at path. This will also expand all parent rows of path as necessary.

Available since: 2.2

gtk_tree_view_get_activate_on_single_click

Gets the setting set by gtk_tree_view_set_activate_on_single_click().

Available since: 3.8

gtk_tree_view_get_background_area

Fills the bounding rectangle in bin_window coordinates for the cell at the row specified by path and the column specified by column. If path is NULL, or points to a node not found in the tree, the y and height fields of the rectangle will be filled with 0. If column is NULL, the x and width fields will be filled with 0. The returned rectangle is equivalent to the background_area passed to gtk_cell_renderer_render(). These background areas tile to cover the entire bin window. Contrast with the cell_area, returned by gtk_tree_view_get_cell_area(), which returns only the cell itself, excluding surrounding borders and the tree expander area.

gtk_tree_view_get_bin_window

Returns the window that tree_view renders to. This is used primarily to compare to event->window to confirm that the event on tree_view is on the right window.

gtk_tree_view_get_cell_area

Fills the bounding rectangle in bin_window coordinates for the cell at the row specified by path and the column specified by column. If path is NULL, or points to a path not currently displayed, the y and height fields of the rectangle will be filled with 0. If column is NULL, the x and width fields will be filled with 0. The sum of all cell rects does not cover the entire tree; there are extra pixels in between rows, for example. The returned rectangle is equivalent to the cell_area passed to gtk_cell_renderer_render(). This function is only valid if tree_view is realized.

gtk_tree_view_get_column

Gets the GtkTreeViewColumn at the given position in the #tree_view.

gtk_tree_view_get_columns

Returns a GList of all the GtkTreeViewColumn s currently in tree_view. The returned list must be freed with g_list_free ().

gtk_tree_view_get_cursor

Fills in path and focus_column with the current path and focus column. If the cursor isn’t currently set, then path will be NULL. If no column currently has focus, then focus_column will be NULL.

gtk_tree_view_get_dest_row_at_pos

Determines the destination row for a given position. drag_x and drag_y are expected to be in widget coordinates. This function is only meaningful if tree_view is realized. Therefore this function will always return FALSE if tree_view is not realized or does not have a model.

gtk_tree_view_get_drag_dest_row

Gets information about the row that is highlighted for feedback.

gtk_tree_view_get_enable_search

Returns whether or not the tree allows to start interactive searching by typing in text.

gtk_tree_view_get_enable_tree_lines

Returns whether or not tree lines are drawn in tree_view.

Available since: 2.10

gtk_tree_view_get_expander_column

Returns the column that is the current expander column. This column has the expander arrow drawn next to it.

gtk_tree_view_get_fixed_height_mode

Returns whether fixed height mode is turned on for tree_view.

Available since: 2.6

gtk_tree_view_get_grid_lines

Returns which grid lines are enabled in tree_view.

Available since: 2.10

gtk_tree_view_get_hadjustment

Gets the GtkAdjustment currently being used for the horizontal aspect.

Deprecated since: 3.0

gtk_tree_view_get_headers_clickable

Returns whether all header columns are clickable.

Available since: 2.10

gtk_tree_view_get_headers_visible

Returns TRUE if the headers on the tree_view are visible.

gtk_tree_view_get_hover_expand

Returns whether hover expansion mode is turned on for tree_view.

Available since: 2.6

gtk_tree_view_get_hover_selection

Returns whether hover selection mode is turned on for tree_view.

Available since: 2.6

gtk_tree_view_get_level_indentation

Returns the amount, in pixels, of extra indentation for child levels in tree_view.

Available since: 2.12

gtk_tree_view_get_model

Returns the model the GtkTreeView is based on. Returns NULL if the model is unset.

gtk_tree_view_get_n_columns

Queries the number of columns in the given tree_view.

Available since: 3.4

gtk_tree_view_get_path_at_pos

Finds the path at the point (x, y), relative to bin_window coordinates (please see gtk_tree_view_get_bin_window()). That is, x and y are relative to an events coordinates. x and y must come from an event on the tree_view only where event->window == gtk_tree_view_get_bin_window (). It is primarily for things like popup menus. If path is non-NULL, then it will be filled with the GtkTreePath at that point. This path should be freed with gtk_tree_path_free(). If column is non-NULL, then it will be filled with the column at that point. cell_x and cell_y return the coordinates relative to the cell background (i.e. the background_area passed to gtk_cell_renderer_render()). This function is only meaningful if tree_view is realized. Therefore this function will always return FALSE if tree_view is not realized or does not have a model.

gtk_tree_view_get_reorderable

Retrieves whether the user can reorder the tree via drag-and-drop. See gtk_tree_view_set_reorderable().

gtk_tree_view_get_row_separator_func

Returns the current row separator function.

Available since: 2.6

gtk_tree_view_get_rubber_banding

Returns whether rubber banding is turned on for tree_view. If the selection mode is #GTK_SELECTION_MULTIPLE, rubber banding will allow the user to select multiple rows by dragging the mouse.

Available since: 2.10

gtk_tree_view_get_rules_hint

Gets the setting set by gtk_tree_view_set_rules_hint().

gtk_tree_view_get_search_column

Gets the column searched on by the interactive search code.

gtk_tree_view_get_search_entry

Returns the GtkEntry which is currently in use as interactive search entry for tree_view. In case the built-in entry is being used, NULL will be returned.

Available since: 2.10

gtk_tree_view_get_search_equal_func

Returns the compare function currently in use.

gtk_tree_view_get_search_position_func

Returns the positioning function currently in use.

Available since: 2.10

Available since: 2.12

gtk_tree_view_get_tooltip_column

Returns the column of tree_view’s model which is being used for displaying tooltips on tree_view’s rows.

Available since: 2.12

gtk_tree_view_get_tooltip_context

This function is supposed to be used in a GtkWidget::query-tooltip signal handler for GtkTreeView. The x, y and keyboard_tip values which are received in the signal handler, should be passed to this function without modification.

Available since: 2.12

gtk_tree_view_get_vadjustment

Gets the GtkAdjustment currently being used for the vertical aspect.

Deprecated since: 3.0

gtk_tree_view_get_visible_range

Sets start_path and end_path to be the first and last visible path. Note that there may be invisible paths in between.

Available since: 2.8

gtk_tree_view_get_visible_rect

Fills visible_rect with the currently-visible region of the buffer, in tree coordinates. Convert to bin_window coordinates with gtk_tree_view_convert_tree_to_bin_window_coords(). Tree coordinates start at 0,0 for row 0 of the tree, and cover the entire scrollable area of the tree.

gtk_tree_view_insert_column

This inserts the column into the tree_view at position. If position is -1, then the column is inserted at the end. If tree_view has “fixed_height” mode enabled, then column must have its “sizing” property set to be GTK_TREE_VIEW_COLUMN_FIXED.

gtk_tree_view_insert_column_with_attributes

Creates a new GtkTreeViewColumn and inserts it into the tree_view at position. If position is -1, then the newly created column is inserted at the end. The column is initialized with the attributes given. If tree_view has “fixed_height” mode enabled, then the new column will have its sizing property set to be GTK_TREE_VIEW_COLUMN_FIXED.

gtk_tree_view_insert_column_with_data_func

Convenience function that inserts a new column into the GtkTreeView with the given cell renderer and a GtkTreeCellDataFunc to set cell renderer attributes (normally using data from the model). See also gtk_tree_view_column_set_cell_data_func(), gtk_tree_view_column_pack_start(). If tree_view has “fixed_height” mode enabled, then the new column will have its “sizing” property set to be GTK_TREE_VIEW_COLUMN_FIXED.

gtk_tree_view_is_blank_at_pos

Determine whether the point (x, y) in tree_view is blank, that is no cell content nor an expander arrow is drawn at the location. If so, the location can be considered as the background. You might wish to take special action on clicks on the background, such as clearing a current selection, having a custom context menu or starting rubber banding.

Available since: 3.0

gtk_tree_view_is_rubber_banding_active

Returns whether a rubber banding operation is currently being done in tree_view.

Available since: 2.12

gtk_tree_view_map_expanded_rows

Calls func on all expanded rows.

gtk_tree_view_move_column_after

Moves column to be after to base_column. If base_column is NULL, then column is placed in the first position.

gtk_tree_view_remove_column

Removes column from tree_view.

gtk_tree_view_row_activated

Activates the cell determined by path and column.

gtk_tree_view_row_expanded

Returns TRUE if the node pointed to by path is expanded in tree_view.

gtk_tree_view_scroll_to_cell

Moves the alignments of tree_view to the position specified by column and path. If column is NULL, then no horizontal scrolling occurs. Likewise, if path is NULL no vertical scrolling occurs. At a minimum, one of column or path need to be non-NULL. row_align determines where the row is placed, and col_align determines where column is placed. Both are expected to be between 0.0 and 1.0. 0.0 means left/top alignment, 1.0 means right/bottom alignment, 0.5 means center.

gtk_tree_view_scroll_to_point

Scrolls the tree view such that the top-left corner of the visible area is tree_x, tree_y, where tree_x and tree_y are specified in tree coordinates. The tree_view must be realized before this function is called. If it isn’t, you probably want to be using gtk_tree_view_scroll_to_cell().

gtk_tree_view_set_activate_on_single_click

Cause the GtkTreeView::row-activated signal to be emitted on a single click instead of a double click.

Available since: 3.8

gtk_tree_view_set_column_drag_function

Sets a user function for determining where a column may be dropped when dragged. This function is called on every column pair in turn at the beginning of a column drag to determine where a drop can take place. The arguments passed to func are: the tree_view, the GtkTreeViewColumn being dragged, the two GtkTreeViewColumn s determining the drop spot, and user_data. If either of the GtkTreeViewColumn arguments for the drop spot are NULL, then they indicate an edge. If func is set to be NULL, then tree_view reverts to the default behavior of allowing all columns to be dropped everywhere.

gtk_tree_view_set_cursor

Sets the current keyboard focus to be at path, and selects it. This is useful when you want to focus the user’s attention on a particular row. If focus_column is not NULL, then focus is given to the column specified by it. Additionally, if focus_column is specified, and start_editing is TRUE, then editing should be started in the specified cell. This function is often followed by gtk_widget_grab_focus (tree_view) in order to give keyboard focus to the widget. Please note that editing can only happen when the widget is realized.

gtk_tree_view_set_cursor_on_cell

Sets the current keyboard focus to be at path, and selects it. This is useful when you want to focus the user’s attention on a particular row. If focus_column is not NULL, then focus is given to the column specified by it. If focus_column and focus_cell are not NULL, and focus_column contains 2 or more editable or activatable cells, then focus is given to the cell specified by focus_cell. Additionally, if focus_column is specified, and start_editing is TRUE, then editing should be started in the specified cell. This function is often followed by gtk_widget_grab_focus (tree_view) in order to give keyboard focus to the widget. Please note that editing can only happen when the widget is realized.

Available since: 2.2

gtk_tree_view_set_destroy_count_func

This function should almost never be used. It is meant for private use by ATK for determining the number of visible children that are removed when the user collapses a row, or a row is deleted.

Deprecated since: 3.4

gtk_tree_view_set_drag_dest_row

Sets the row that is highlighted for feedback. If path is NULL, an existing highlight is removed.

gtk_tree_view_set_enable_search

If enable_search is set, then the user can type in text to search through the tree interactively (this is sometimes called “typeahead find”).

gtk_tree_view_set_enable_tree_lines

Sets whether to draw lines interconnecting the expanders in tree_view. This does not have any visible effects for lists.

Available since: 2.10

gtk_tree_view_set_expander_column

Sets the column to draw the expander arrow at. It must be in tree_view. If column is NULL, then the expander arrow is always at the first visible column.

gtk_tree_view_set_fixed_height_mode

Enables or disables the fixed height mode of tree_view. Fixed height mode speeds up GtkTreeView by assuming that all rows have the same height. Only enable this option if all rows are the same height and all columns are of type GTK_TREE_VIEW_COLUMN_FIXED.

Available since: 2.6

gtk_tree_view_set_grid_lines

Sets which grid lines to draw in tree_view.

Available since: 2.10

gtk_tree_view_set_hadjustment

Sets the GtkAdjustment for the current horizontal aspect.

Deprecated since: 3.0

gtk_tree_view_set_headers_clickable

Allow the column title buttons to be clicked.

gtk_tree_view_set_headers_visible

Sets the visibility state of the headers.

gtk_tree_view_set_hover_expand

Enables or disables the hover expansion mode of tree_view. Hover expansion makes rows expand or collapse if the pointer moves over them.

Available since: 2.6

gtk_tree_view_set_hover_selection

Enables or disables the hover selection mode of tree_view. Hover selection makes the selected row follow the pointer. Currently, this works only for the selection modes GTK_SELECTION_SINGLE and GTK_SELECTION_BROWSE.

Available since: 2.6

gtk_tree_view_set_level_indentation

Sets the amount of extra indentation for child levels to use in tree_view in addition to the default indentation. The value should be specified in pixels, a value of 0 disables this feature and in this case only the default indentation will be used. This does not have any visible effects for lists.

Available since: 2.12

gtk_tree_view_set_model

Sets the model for a GtkTreeView. If the tree_view already has a model set, it will remove it before setting the new model. If model is NULL, then it will unset the old model.

gtk_tree_view_set_reorderable

This function is a convenience function to allow you to reorder models that support the GtkTreeDragSourceIface and the GtkTreeDragDestIface. Both GtkTreeStore and GtkListStore support these. If reorderable is TRUE, then the user can reorder the model by dragging and dropping rows. The developer can listen to these changes by connecting to the model’s GtkTreeModel::row-inserted and GtkTreeModel::row-deleted signals. The reordering is implemented by setting up the tree view as a drag source and destination. Therefore, drag and drop can not be used in a reorderable view for any other purpose.

gtk_tree_view_set_row_separator_func

Sets the row separator function, which is used to determine whether a row should be drawn as a separator. If the row separator function is NULL, no separators are drawn. This is the default value.

Available since: 2.6

gtk_tree_view_set_rubber_banding

Enables or disables rubber banding in tree_view. If the selection mode is #GTK_SELECTION_MULTIPLE, rubber banding will allow the user to select multiple rows by dragging the mouse.

Available since: 2.10

gtk_tree_view_set_rules_hint

Sets a hint for the theme to draw even/odd rows in the tree_view with different colors, also known as “zebra striping”.

gtk_tree_view_set_search_column

Sets column as the column where the interactive search code should search in for the current model.

gtk_tree_view_set_search_entry

Sets the entry which the interactive search code will use for this tree_view. This is useful when you want to provide a search entry in our interface at all time at a fixed position. Passing NULL for entry will make the interactive search code use the built-in popup entry again.

Available since: 2.10

gtk_tree_view_set_search_equal_func

Sets the compare function for the interactive search capabilities; note that somewhat like strcmp() returning 0 for equality GtkTreeViewSearchEqualFunc returns FALSE on matches.

gtk_tree_view_set_search_position_func

Sets the function to use when positioning the search dialog.

Available since: 2.10

gtk_tree_view_set_show_expanders

Sets whether to draw and enable expanders and indent child rows in tree_view. When disabled there will be no expanders visible in trees and there will be no way to expand and collapse rows by default. Also note that hiding the expanders will disable the default indentation. You can set a custom indentation in this case using gtk_tree_view_set_level_indentation(). This does not have any visible effects for lists.

Available since: 2.12

gtk_tree_view_set_tooltip_cell

Sets the tip area of tooltip to the area path, column and cell have in common. For example if path is NULL and column is set, the tip area will be set to the full area covered by column. See also gtk_tooltip_set_tip_area().

Available since: 2.12

gtk_tree_view_set_tooltip_column

If you only plan to have simple (text-only) tooltips on full rows, you can use this function to have GtkTreeView handle these automatically for you. column should be set to the column in tree_view’s model containing the tooltip texts, or -1 to disable this feature.

Available since: 2.12

gtk_tree_view_set_tooltip_row

Sets the tip area of tooltip to be the area covered by the row at path. See also gtk_tree_view_set_tooltip_column() for a simpler alternative. See also gtk_tooltip_set_tip_area().

Available since: 2.12

gtk_tree_view_set_vadjustment

Sets the GtkAdjustment for the current vertical aspect.

Deprecated since: 3.0

gtk_tree_view_unset_rows_drag_dest

Undoes the effect of gtk_tree_view_enable_model_drag_dest(). Calling this method sets GtkTreeView:reorderable to FALSE.

gtk_tree_view_unset_rows_drag_source

Undoes the effect of gtk_tree_view_enable_model_drag_source(). Calling this method sets GtkTreeView:reorderable to FALSE.

Methods inherited from GtkContainer (33)
gtk_container_add

Adds widget to container. Typically used for simple containers such as GtkWindow, GtkFrame, or GtkButton; for more complicated layout containers such as GtkBox or GtkGrid, this function will pick default packing parameters that may not be correct. So consider functions such as gtk_box_pack_start() and gtk_grid_attach() as an alternative to gtk_container_add() in those cases. A widget may be added to only one container at a time; you can’t place the same widget inside two different containers.

gtk_container_add_with_properties

Adds widget to container, setting child properties at the same time. See gtk_container_add() and gtk_container_child_set() for more details.

gtk_container_check_resize
No description available.
gtk_container_child_get

Gets the values of one or more child properties for child and container.

gtk_container_child_get_property

Gets the value of a child property for child and container.

gtk_container_child_get_valist

Gets the values of one or more child properties for child and container.

gtk_container_child_notify

Emits a GtkWidget::child-notify signal for the [child property][child-properties] child_property on the child.

Available since: 3.2

gtk_container_child_notify_by_pspec

Emits a GtkWidget::child-notify signal for the [child property][child-properties] specified by pspec on the child.

Available since: 3.18

gtk_container_child_set

Sets one or more child properties for child and container.

gtk_container_child_set_property

Sets a child property for child and container.

gtk_container_child_set_valist

Sets one or more child properties for child and container.

gtk_container_child_type

Returns the type of the children supported by the container.

gtk_container_forall

Invokes callback on each direct child of container, including children that are considered “internal” (implementation details of the container). “Internal” children generally weren’t added by the user of the container, but were added by the container implementation itself.

gtk_container_foreach

Invokes callback on each non-internal child of container. See gtk_container_forall() for details on what constitutes an “internal” child. For all practical purposes, this function should iterate over precisely those child widgets that were added to the container by the application with explicit add() calls.

gtk_container_get_border_width

Retrieves the border width of the container. See gtk_container_set_border_width().

gtk_container_get_children

Returns the container’s non-internal children. See gtk_container_forall() for details on what constitutes an “internal” child.

gtk_container_get_focus_chain

Retrieves the focus chain of the container, if one has been set explicitly. If no focus chain has been explicitly set, GTK+ computes the focus chain based on the positions of the children. In that case, GTK+ stores NULL in focusable_widgets and returns FALSE.

Deprecated since: 3.24

gtk_container_get_focus_child

Returns the current focus child widget inside container. This is not the currently focused widget. That can be obtained by calling gtk_window_get_focus().

Available since: 2.14

gtk_container_get_focus_hadjustment

Retrieves the horizontal focus adjustment for the container. See gtk_container_set_focus_hadjustment ().

gtk_container_get_focus_vadjustment

Retrieves the vertical focus adjustment for the container. See gtk_container_set_focus_vadjustment().

gtk_container_get_path_for_child

Returns a newly created widget path representing all the widget hierarchy from the toplevel down to and including child.

gtk_container_get_resize_mode

Returns the resize mode for the container. See gtk_container_set_resize_mode ().

Deprecated since: 3.12

gtk_container_propagate_draw

When a container receives a call to the draw function, it must send synthetic GtkWidget::draw calls to all children that don’t have their own GdkWindows. This function provides a convenient way of doing this. A container, when it receives a call to its GtkWidget::draw function, calls gtk_container_propagate_draw() once for each child, passing in the cr the container received.

Methods inherited from GtkWidget (263)
gtk_widget_activate

For widgets that can be “activated” (buttons, menu items, etc.) this function activates them. Activation is what happens when you press Enter on a widget during key navigation. If widget isn’t activatable, the function returns FALSE.

gtk_widget_add_accelerator

Installs an accelerator for this widget in accel_group that causes accel_signal to be emitted if the accelerator is activated. The accel_group needs to be added to the widget’s toplevel via gtk_window_add_accel_group(), and the signal must be of type G_SIGNAL_ACTION. Accelerators added through this function are not user changeable during runtime. If you want to support accelerators that can be changed by the user, use gtk_accel_map_add_entry() and gtk_widget_set_accel_path() or gtk_menu_item_set_accel_path() instead.

gtk_widget_add_device_events

Adds the device events in the bitfield events to the event mask for widget. See gtk_widget_set_device_events() for details.

Available since: 3.0

gtk_widget_add_events

Adds the events in the bitfield events to the event mask for widget. See gtk_widget_set_events() and the [input handling overview][event-masks] for details.

gtk_widget_add_mnemonic_label

Adds a widget to the list of mnemonic labels for this widget. (See gtk_widget_list_mnemonic_labels()). Note the list of mnemonic labels for the widget is cleared when the widget is destroyed, so the caller must make sure to update its internal state at this point as well, by using a connection to the GtkWidget::destroy signal or a weak notifier.

Available since: 2.4

gtk_widget_add_tick_callback

Queues an animation frame update and adds a callback to be called before each frame. Until the tick callback is removed, it will be called frequently (usually at the frame rate of the output device or as quickly as the application can be repainted, whichever is slower). For this reason, is most suitable for handling graphics that change every frame or every few frames. The tick callback does not automatically imply a relayout or repaint. If you want a repaint or relayout, and aren’t changing widget properties that would trigger that (for example, changing the text of a GtkLabel), then you will have to call gtk_widget_queue_resize() or gtk_widget_queue_draw_area() yourself.

Available since: 3.8

gtk_widget_can_activate_accel

Determines whether an accelerator that activates the signal identified by signal_id can currently be activated. This is done by emitting the GtkWidget::can-activate-accel signal on widget; if the signal isn’t overridden by a handler or in a derived widget, then the default check is that the widget must be sensitive, and the widget and all its ancestors mapped.

Available since: 2.4

gtk_widget_child_focus

This function is used by custom widget implementations; if you’re writing an app, you’d use gtk_widget_grab_focus() to move the focus to a particular widget, and gtk_container_set_focus_chain() to change the focus tab order. So you may want to investigate those functions instead.

gtk_widget_child_notify

Emits a GtkWidget::child-notify signal for the [child property][child-properties] child_property on widget.

gtk_widget_class_path

Same as gtk_widget_path(), but always uses the name of a widget’s type, never uses a custom name set with gtk_widget_set_name().

Deprecated since: 3.0

gtk_widget_compute_expand

Computes whether a container should give this widget extra space when possible. Containers should check this, rather than looking at gtk_widget_get_hexpand() or gtk_widget_get_vexpand().

gtk_widget_create_pango_context

Creates a new PangoContext with the appropriate font map, font options, font description, and base direction for drawing text for this widget. See also gtk_widget_get_pango_context().

gtk_widget_create_pango_layout

Creates a new PangoLayout with the appropriate font map, font description, and base direction for drawing text for this widget.

gtk_widget_destroy

Destroys a widget.

gtk_widget_destroyed

This function sets *widget_pointer to NULL if widget_pointer != NULL. It’s intended to be used as a callback connected to the “destroy” signal of a widget. You connect gtk_widget_destroyed() as a signal handler, and pass the address of your widget variable as user data. Then when the widget is destroyed, the variable will be set to NULL. Useful for example to avoid multiple copies of the same dialog.

gtk_widget_device_is_shadowed

Returns TRUE if device has been shadowed by a GTK+ device grab on another widget, so it would stop sending events to widget. This may be used in the GtkWidget::grab-notify signal to check for specific devices. See gtk_device_grab_add().

Available since: 3.0

gtk_drag_begin

This function is equivalent to gtk_drag_begin_with_coordinates(), passing -1, -1 as coordinates.

Deprecated since: 3.10

gtk_drag_begin_with_coordinates

Initiates a drag on the source side. The function only needs to be used when the application is starting drags itself, and is not needed when gtk_drag_source_set() is used.

Available since: 3.10

gtk_drag_check_threshold

Checks to see if a mouse drag starting at (start_x, start_y) and ending at (current_x, current_y) has passed the GTK+ drag threshold, and thus should trigger the beginning of a drag-and-drop operation.

gtk_drag_dest_add_image_targets

Add the image targets supported by GtkSelectionData to the target list of the drag destination. The targets are added with info = 0. If you need another value, use gtk_target_list_add_image_targets() and gtk_drag_dest_set_target_list().

Available since: 2.6

gtk_drag_dest_add_text_targets

Add the text targets supported by GtkSelectionData to the target list of the drag destination. The targets are added with info = 0. If you need another value, use gtk_target_list_add_text_targets() and gtk_drag_dest_set_target_list().

Available since: 2.6

gtk_drag_dest_add_uri_targets

Add the URI targets supported by GtkSelectionData to the target list of the drag destination. The targets are added with info = 0. If you need another value, use gtk_target_list_add_uri_targets() and gtk_drag_dest_set_target_list().

Available since: 2.6

gtk_drag_dest_find_target

Looks for a match between the supported targets of context and the dest_target_list, returning the first matching target, otherwise returning GDK_NONE. dest_target_list should usually be the return value from gtk_drag_dest_get_target_list(), but some widgets may have different valid targets for different parts of the widget; in that case, they will have to implement a drag_motion handler that passes the correct target list to this function.

Gtk.TreeView::cursor-changed

The position of the cursor (focused cell) has changed.

Gtk.TreeView::expand-collapse-cursor-row
No description available.
Gtk.TreeView::move-cursor

The GtkTreeView::move-cursor signal is a [keybinding signal][GtkBindingSignal] which gets emitted when the user presses one of the cursor keys.

Gtk.TreeView::row-activated

The “row-activated” signal is emitted when the method gtk_tree_view_row_activated() is called, when the user double clicks a treeview row with the “activate-on-single-click” property set to FALSE, or when the user single clicks a row when the “activate-on-single-click” property set to TRUE. It is also emitted when a non-editable row is selected and one of the keys: Space, Shift+Space, Return or Enter is pressed.

No description available.
Gtk.Widget::button-press-event

The ::button-press-event signal will be emitted when a button (typically from a mouse) is pressed.

Gtk.Widget::button-release-event

The ::button-release-event signal will be emitted when a button (typically from a mouse) is released.

Gtk.Widget::can-activate-accel

Determines whether an accelerator that activates the signal identified by signal_id can currently be activated. This signal is present to allow applications and derived widgets to override the default GtkWidget handling for determining whether an accelerator can be activated.

Gtk.Widget::child-notify

The ::child-notify signal is emitted for each [child property][child-properties] that has changed on an object. The signal’s detail holds the property name.

Gtk.Widget::composited-changed

The ::composited-changed signal is emitted when the composited status of widgets screen changes. See gdk_screen_is_composited().

Deprecated since: 3.22

Gtk.Widget::configure-event

The ::configure-event signal will be emitted when the size, position or stacking of the widgets window has changed.

Gtk.Widget::damage-event

Emitted when a redirected window belonging to widget gets drawn into. The region/area members of the event shows what area of the redirected drawable was drawn into.

Available since: 2.14

Gtk.Widget::delete-event

The ::delete-event signal is emitted if a user requests that a toplevel window is closed. The default handler for this signal destroys the window. Connecting gtk_widget_hide_on_delete() to this signal will cause the window to be hidden instead, so that it can later be shown again without reconstructing it.

Gtk.Widget::destroy

Signals that all holders of a reference to the widget should release the reference that they hold. May result in finalization of the widget if all references are released.

Gtk.Widget::destroy-event

The ::destroy-event signal is emitted when a GdkWindow is destroyed. You rarely get this signal, because most widgets disconnect themselves from their window before they destroy it, so no widget owns the window at destroy time.

Gtk.Widget::direction-changed

The ::direction-changed signal is emitted when the text direction of a widget changes.

Gtk.Widget::drag-begin

The ::drag-begin signal is emitted on the drag source when a drag is started. A typical reason to connect to this signal is to set up a custom drag icon with e.g. gtk_drag_source_set_icon_pixbuf().

Gtk.Widget::drag-data-delete

The ::drag-data-delete signal is emitted on the drag source when a drag with the action GDK_ACTION_MOVE is successfully completed. The signal handler is responsible for deleting the data that has been dropped. What “delete” means depends on the context of the drag operation.

Gtk.Widget::drag-data-get

The ::drag-data-get signal is emitted on the drag source when the drop site requests the data which is dragged. It is the responsibility of the signal handler to fill data with the data in the format which is indicated by info. See gtk_selection_data_set() and gtk_selection_data_set_text().

Gtk.Widget::drag-data-received

The ::drag-data-received signal is emitted on the drop site when the dragged data has been received. If the data was received in order to determine whether the drop will be accepted, the handler is expected to call gdk_drag_status() and not finish the drag. If the data was received in response to a GtkWidget::drag-drop signal (and this is the last target to be received), the handler for this signal is expected to process the received data and then call gtk_drag_finish(), setting the success parameter depending on whether the data was processed successfully.

Gtk.Widget::drag-drop

The ::drag-drop signal is emitted on the drop site when the user drops the data onto the widget. The signal handler must determine whether the cursor position is in a drop zone or not. If it is not in a drop zone, it returns FALSE and no further processing is necessary. Otherwise, the handler returns TRUE. In this case, the handler must ensure that gtk_drag_finish() is called to let the source know that the drop is done. The call to gtk_drag_finish() can be done either directly or in a GtkWidget::drag-data-received handler which gets triggered by calling gtk_drag_get_data() to receive the data for one or more of the supported targets.

Gtk.Widget::drag-end

The ::drag-end signal is emitted on the drag source when a drag is finished. A typical reason to connect to this signal is to undo things done in GtkWidget::drag-begin.

Gtk.Widget::drag-failed

The ::drag-failed signal is emitted on the drag source when a drag has failed. The signal handler may hook custom code to handle a failed DnD operation based on the type of error, it returns TRUE is the failure has been already handled (not showing the default “drag operation failed” animation), otherwise it returns FALSE.

Available since: 2.12

Gtk.Widget::drag-leave

The ::drag-leave signal is emitted on the drop site when the cursor leaves the widget. A typical reason to connect to this signal is to undo things done in GtkWidget::drag-motion, e.g. undo highlighting with gtk_drag_unhighlight().

Gtk.Widget::drag-motion

The ::drag-motion signal is emitted on the drop site when the user moves the cursor over the widget during a drag. The signal handler must determine whether the cursor position is in a drop zone or not. If it is not in a drop zone, it returns FALSE and no further processing is necessary. Otherwise, the handler returns TRUE. In this case, the handler is responsible for providing the necessary information for displaying feedback to the user, by calling gdk_drag_status().

Gtk.Widget::draw

This signal is emitted when a widget is supposed to render itself. The widgets top left corner must be painted at the origin of the passed in context and be sized to the values returned by gtk_widget_get_allocated_width() and gtk_widget_get_allocated_height().

Available since: 3.0

Gtk.Widget::enter-notify-event

The ::enter-notify-event will be emitted when the pointer enters the widgets window.

Gtk.Widget::event

The GTK+ main loop will emit three signals for each GDK event delivered to a widget: one generic ::event signal, another, more specific, signal that matches the type of event delivered (e.g. GtkWidget::key-press-event) and finally a generic GtkWidget::event-after signal.

Gtk.Widget::event-after

After the emission of the GtkWidget::event signal and (optionally) the second more specific signal, ::event-after will be emitted regardless of the previous two signals handlers return values.

Gtk.Widget::focus
No description available.
Gtk.Widget::focus-in-event

The ::focus-in-event signal will be emitted when the keyboard focus enters the widgets window.

Gtk.Widget::focus-out-event

The ::focus-out-event signal will be emitted when the keyboard focus leaves the widgets window.

Gtk.Widget::grab-broken-event

Emitted when a pointer or keyboard grab on a window belonging to widget gets broken.

Available since: 2.8

Gtk.Widget::grab-focus
No description available.
Gtk.Widget::grab-notify

The ::grab-notify signal is emitted when a widget becomes shadowed by a GTK+ grab (not a pointer or keyboard grab) on another widget, or when it becomes unshadowed due to a grab being removed.

Gtk.Widget::hide

The ::hide signal is emitted when widget is hidden, for example with gtk_widget_hide().

Gtk.Widget::hierarchy-changed

The ::hierarchy-changed signal is emitted when the anchored state of a widget changes. A widget is “anchored” when its toplevel ancestor is a GtkWindow. This signal is emitted when a widget changes from un-anchored to anchored or vice-versa.

Gtk.Widget::key-press-event

The ::key-press-event signal is emitted when a key is pressed. The signal emission will reoccur at the key-repeat rate when the key is kept pressed.

Gtk.Widget::key-release-event

The ::key-release-event signal is emitted when a key is released.

Gtk.Widget::keynav-failed

Gets emitted if keyboard navigation fails. See gtk_widget_keynav_failed() for details.

Available since: 2.12

Gtk.Widget::leave-notify-event

The ::leave-notify-event will be emitted when the pointer leaves the widgets window.

Gtk.Widget::map

The ::map signal is emitted when widget is going to be mapped, that is when the widget is visible (which is controlled with gtk_widget_set_visible()) and all its parents up to the toplevel widget are also visible. Once the map has occurred, GtkWidget::map-event will be emitted.

Gtk.Widget::map-event

The ::map-event signal will be emitted when the widgets window is mapped. A window is mapped when it becomes visible on the screen.

Gtk.Widget::mnemonic-activate

The default handler for this signal activates widget if group_cycling is FALSE, or just makes widget grab focus if group_cycling is TRUE.

Gtk.Widget::motion-notify-event

The ::motion-notify-event signal is emitted when the pointer moves over the widget’s GdkWindow.

Gtk.Widget::move-focus
No description available.
Gtk.Widget::parent-set

The ::parent-set signal is emitted when a new parent has been set on a widget.

Gtk.Widget::popup-menu

This signal gets emitted whenever a widget should pop up a context menu. This usually happens through the standard key binding mechanism; by pressing a certain key while a widget is focused, the user can cause the widget to pop up a menu. For example, the GtkEntry widget creates a menu with clipboard commands. See the [Popup Menu Migration Checklist][checklist-popup-menu] for an example of how to use this signal.

Gtk.Widget::property-notify-event

The ::property-notify-event signal will be emitted when a property on the widgets window has been changed or deleted.

Gtk.Widget::proximity-in-event

To receive this signal the GdkWindow associated to the widget needs to enable the #GDK_PROXIMITY_IN_MASK mask.

Gtk.Widget::proximity-out-event

To receive this signal the GdkWindow associated to the widget needs to enable the #GDK_PROXIMITY_OUT_MASK mask.

Gtk.Widget::query-tooltip

Emitted when GtkWidget:has-tooltip is TRUE and the hover timeout has expired with the cursor hovering “above” widget; or emitted when widget got focus in keyboard mode.

Available since: 2.12

Gtk.Widget::realize

The ::realize signal is emitted when widget is associated with a GdkWindow, which means that gtk_widget_realize() has been called or the widget has been mapped (that is, it is going to be drawn).

Gtk.Widget::screen-changed

The ::screen-changed signal gets emitted when the screen of a widget has changed.

Gtk.Widget::scroll-event

The ::scroll-event signal is emitted when a button in the 4 to 7 range is pressed. Wheel mice are usually configured to generate button press events for buttons 4 and 5 when the wheel is turned.

Gtk.Widget::selection-clear-event

The ::selection-clear-event signal will be emitted when the the widgets window has lost ownership of a selection.

Deprecated since: 3.0

Gtk.Widget::style-updated

The ::style-updated signal is a convenience signal that is emitted when the GtkStyleContext::changed signal is emitted on the widgets associated GtkStyleContext as returned by gtk_widget_get_style_context().

Available since: 3.0

Gtk.Widget::touch-event
No description available.
