gboolean gdk_drag_context_manage_dnd ( GdkDragContext* context, GdkWindow* ipc_window, GdkDragAction actions )
Requests the drag and drop operation to be managed by
When a drag and drop operation becomes managed, the
will internally handle all input and source-side
as required by the windowing system.
Once the drag and drop operation is managed, the drag context will
emit the following signals:
GdkDragContext::action-changed signal whenever the final action
to be performed by the drag and drop operation changes.
GdkDragContext::drop-performed signal after the user performs
the drag and drop gesture (typically by releasing the mouse button).
GdkDragContext::dnd-finished signal after the drag and drop
operation concludes (after all
GdkSelection transfers happen).
GdkDragContext::cancel signal if the drag and drop operation is
finished but doesn’t happen over an accepting destination, or is
cancelled through other means.
