DragIcon

class DragIcon(**properties: Any)

Superclasses: Widget, InitiallyUnowned, Object

Implemented Interfaces: Accessible, Buildable, ConstraintTarget, Native, Root

GtkDragIcon is a GtkRoot implementation for drag icons.

A drag icon moves with the pointer during a Drag-and-Drop operation and is destroyed when the drag ends.

To set up a drag icon and associate it with an ongoing drag operation, use get_for_drag to get the icon for a drag. You can then use it like any other widget and use set_child to set whatever widget should be used for the drag icon.

Keep in mind that drag icons do not allow user input.

Constructors

class DragIcon

classmethod get_for_drag(drag: Drag) → Widget

Gets the GtkDragIcon in use with drag.

If no drag icon exists yet, a new one will be created and shown.

Parameters:

drag – a GdkDrag

Methods

class DragIcon

create_widget_for_value(value: Any) → Widget | None

Creates a widget that can be used as a drag icon for the given value.

Supported types include strings, GdkRGBA and GtkTextBuffer. If GTK does not know how to create a widget for a given value, it will return None.

This method is used to set the default drag icon on drag-and-drop operations started by GtkDragSource, so you don’t need to set a drag icon using this function there.

Parameters:

value – a GValue

get_child() → Widget | None

Gets the widget currently used as drag icon.

set_child(child: Widget | None = None) → None

Sets the widget to display as the drag icon.

Parameters:

child – a GtkWidget

set_from_paintable(drag: Drag, paintable: Paintable, hot_x: int, hot_y: int) → None

Creates a GtkDragIcon that shows paintable, and associates it with the drag operation.

The hotspot position on the paintable is aligned with the hotspot of the cursor.

Parameters:

• drag – a GdkDrag

• paintable – a GdkPaintable to display

• hot_x – X coordinate of the hotspot

• hot_y – Y coordinate of the hotspot
