DragContext.manageDnd

Requests the drag and drop operation to be managed by context. When a drag and drop operation becomes managed, the #GdkDragContext will internally handle all input and source-side #GdkEventDND events as required by the windowing system.

Once the drag and drop operation is managed, the drag context will emit the following signals:

• The #GdkDragContext::action-changed signal whenever the final action to be performed by the drag and drop operation changes.
• The #GdkDragContext::drop-performed signal after the user performs the drag and drop gesture (typically by releasing the mouse button).
• The #GdkDragContext::dnd-finished signal after the drag and drop operation concludes (after all #GdkSelection transfers happen).
• The #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.

  Parameters

  ipcWindow	Window to use for IPC messaging/events
  actions	the actions supported by the drag source

  Returns

  #TRUE if the drag and drop operation is managed.
