Class

GtkDragIcon

Description [src]

final class Gtk.DragIcon : Gtk.Widget {
  /* No available fields */
}

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 gtk_drag_icon_get_for_drag()() to get the icon for a drag. You can then use it like any other widget and use gtk_drag_icon_set_child()() to set whatever widget should be used for the drag icon.

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