Class

GtkHSeparator

Description [src]

class Gtk.HSeparator : Gtk.Separator {
  separator: GtkSeparator
}

The GtkHSeparator widget is a horizontal separator, used to group the widgets within a window. It displays a horizontal line with a shadow to make it appear sunken into the interface.

The GtkHSeparator widget is not used as a separator within menus. To create a separator in a menu create an empty GtkSeparatorMenuItem widget using gtk_separator_menu_item_new() and add it to the menu with gtk_menu_shell_append().

GtkHSeparator has been deprecated, use GtkSeparator instead.

Instance methods

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.

Signals

Signals inherited from GtkWidget (69)
Gtk.Widget::accel-closures-changed
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.

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
