Creates a new empty GtkImage widget.

Creates a GtkImage displaying the given animation. The GtkImage does not assume a reference to the animation; you still need to unref it if you own references. GtkImage will add its own reference rather than adopting yours.

Creates a new GtkImage displaying the file filename. If the file isn’t found or can’t be loaded, the resulting GtkImage will display a "broken image" icon. This function never returns NULL, it always returns a valid GtkImage widget.

Creates a GtkImage displaying an icon from the current icon theme. If the icon name isn’t known, a "broken image" icon will be displayed instead. If the current icon theme is changed, the icon will be updated appropriately.

Creates a GtkImage displaying an icon from the current icon theme. If the icon name isn’t known, a "broken image" icon will be displayed instead. If the current icon theme is changed, the icon will be updated appropriately.

since: 2.6

Creates a GtkImage displaying an icon set. Sample stock sizes are

GTK_ICON_SIZE_MENU, #GTK_ICON_SIZE_SMALL_TOOLBAR. Instead of using

this function, usually it’s better to create a GtkIconFactory, put your icon sets in the icon factory, add the icon factory to the list of default factories with gtk_icon_factory_add_default(), and then use gtk_image_new_from_stock(). This will allow themes to override the icon you ship with your application.

deprecated: 3.10

Creates a new GtkImage displaying pixbuf. The GtkImage does not assume a reference to the pixbuf; you still need to unref it if you own references. GtkImage will add its own reference rather than adopting yours.

Creates a new GtkImage displaying the resource file resource_path. If the file isn’t found or can’t be loaded, the resulting GtkImage will display a "broken image" icon. This function never returns NULL, it always returns a valid GtkImage widget.

The widget’s window if it is realized, NULL otherwise.

since: 2.14

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

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

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.

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.

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

deprecated: 3.22

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

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

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.

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.

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.

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

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().

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.

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().

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.

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.

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.

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

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().

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().

This signal is emitted when a widget is supposed to render itself. The widget‘s 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

The ::enter-notify-event will be emitted when the pointer enters the widget‘s window.

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.

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.

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

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

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

since: 2.8

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.

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

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.

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.

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

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

since: 2.12

The ::leave-notify-event will be emitted when the pointer leaves the widget‘s window.

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.

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

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

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

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

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.

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

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

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

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

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).

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

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.

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

The ::selection-request-event signal will be emitted when another client requests ownership of the selection owned by the widget‘s window.

The ::show signal is emitted when widget is shown, for example with gtk_widget_show().

The ::state-changed signal is emitted when the widget state changes. See gtk_widget_get_state().

deprecated: 3.0

The ::state-flags-changed signal is emitted when the widget state changes, see gtk_widget_get_state_flags().

since: 3.0

The ::style-set signal is emitted when a new style has been set on a widget. Note that style-modifying functions like gtk_widget_modify_base() also cause this signal to be emitted.

deprecated: 3.0

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

since: 3.0

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.

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

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).

The ::visibility-notify-event will be emitted when the widget‘s window is obscured or unobscured.

deprecated: 3.12

The ::window-state-event will be emitted when the state of the toplevel window associated to the widget changes.

The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.
