begin

Description:

public static Drag? begin (Surface surface, Device device, ContentProvider content, DragAction actions, double dx, double dy)

Starts a drag and creates a new drag context for it.

This function is called by the drag source. After this call, you probably want to set up the drag icon using the surface returned by [ method@Gdk.Drag.get_drag_surface].

This function returns a reference to the [class@Gdk.Drag] object, but GTK keeps its own reference as well, as long as the DND operation is going on.

Note: if actions include gdk_action_move, you need to listen for the [signal@Gdk.Drag:GdkDrag:dnd-finished] signal and delete the data at the source if [method@Gdk.Drag.get_selected_action] returns gdk_action_move.

Parameters:

surface	the source surface for this drag
device	the device that controls this drag
content	the offered content
actions	the actions supported by this drag
dx	the x offset to `device`'s position where the drag nominally started
dy	the y offset to `device`'s position where the drag nominally started

Returns:

a newly created `GdkDrag`
