Class

GtkToolItem

Description [src]

class Gtk.ToolItem : Gtk.Bin {
  parent: GtkBin
}

GtkToolItems are widgets that can appear on a toolbar. To create a toolbar item that contain something else than a button, use gtk_tool_item_new(). Use gtk_container_add() to add a child widget to the tool item.

For toolbar items that contain buttons, see the GtkToolButton, GtkToggleToolButton and GtkRadioToolButton classes.

See the GtkToolbar class for a description of the toolbar widget, and GtkToolShell for a description of the tool shell interface.

Signals

Gtk.ToolItem::create-menu-proxy

This signal is emitted when the toolbar needs information from tool_item about whether the item should appear in the toolbar overflow menu. In response the tool item should either.

Gtk.ToolItem::toolbar-reconfigured

This signal is emitted when some property of the toolbar that the item is a child of changes. For custom subclasses of GtkToolItem, the default handler of this signal use the functions - gtk_tool_shell_get_orientation() - gtk_tool_shell_get_style() - gtk_tool_shell_get_icon_size() - gtk_tool_shell_get_relief_style() to find out what the toolbar should look like and change themselves accordingly.

GtkContainer::set-focus-child
No description available.

Signals inherited from GtkWidget (69)
GtkWidget::accel-closures-changed
No description available.

GtkWidget::button-press-event

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

GtkWidget::button-release-event

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

GtkWidget::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.

GtkWidget::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.

GtkWidget::composited-changed

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

deprecated: 3.22 

GtkWidget::configure-event

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

GtkWidget::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.

since: 2.14

GtkWidget::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.

GtkWidget::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.

GtkWidget::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.

GtkWidget::direction-changed

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

GtkWidget::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().

GtkWidget::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.

GtkWidget::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().

GtkWidget::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.

GtkWidget::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.

GtkWidget::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.

GtkWidget::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.

since: 2.12

GtkWidget::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().

GtkWidget::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().

GtkWidget::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().

since: 3.0

GtkWidget::enter-notify-event

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

GtkWidget::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.

GtkWidget::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.

GtkWidget::focus
No description available.

GtkWidget::focus-in-event

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

GtkWidget::focus-out-event

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

GtkWidget::grab-broken-event

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

since: 2.8

GtkWidget::grab-focus
No description available.

GtkWidget::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.

GtkWidget::hide

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

GtkWidget::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.

GtkWidget::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.

GtkWidget::key-release-event

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

GtkWidget::keynav-failed

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

since: 2.12

GtkWidget::leave-notify-event

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

GtkWidget::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.

GtkWidget::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.

GtkWidget::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.

GtkWidget::motion-notify-event

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

GtkWidget::move-focus
No description available.

GtkWidget::parent-set

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

GtkWidget::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.

GtkWidget::property-notify-event

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

GtkWidget::proximity-in-event

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

GtkWidget::proximity-out-event

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

GtkWidget::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.

since: 2.12

GtkWidget::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).

GtkWidget::screen-changed

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

GtkWidget::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.

GtkWidget::selection-clear-event

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

GtkWidget::selection-get

deprecated: 3.0 

GtkWidget::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().

since: 3.0

GtkWidget::touch-event

GtkWidget::unmap

The ::unmap signal is emitted when widget is going to be unmapped, which means that either it or any of its parents up to the toplevel widget have been set as hidden.

GtkWidget::unmap-event

The ::unmap-event signal will be emitted when the widgets window is unmapped. A window is unmapped when it becomes invisible on the screen.

GtkWidget::unrealize

The ::unrealize signal is emitted when the GdkWindow associated with widget is destroyed, which means that gtk_widget_unrealize() has been called or the widget has been unmapped (that is, it is going to be hidden).
