A Gdk::DragContext holds information about a drag in progress.
It is used on both source and destination sides.

| void Gdk::DragContext::drag_finish | ( | bool | success, | 
| bool | del, | ||
| guint32 | time | ||
| ) | 
Informs the drag source that the drop is finished, and that the data of the drag will no longer be required.
| success | A flag indicating whether the drop was successful. | 
| del | Aa flag indicating whether the source should delete the original data. (This should be true for a move.) time The timestamp from the "drag_data_drop" signal. | 
| void Gdk::DragContext::drag_refuse | ( | guint32 | time | ) | 
Indicate that a drop will not be accepted.
This function may be called by the drag destination in response to gdk_drag_motion() called by the drag source. Alternatively, call drag_status() to indicate which drag action will be accepted.
| time | The timestamp for this operation. | 
| void Gdk::DragContext::drag_status | ( | DragAction | action, | 
| guint32 | time | ||
| ) | 
Selects one of the actions offered by the drag source.
This function is called by the drag destination in response to gdk_drag_motion() called by the drag source.
| action | The selected action which will be taken when a drop happens, or 0 to indicate that a drop will not be accepted. | 
| time | The timestamp for this operation. | 
| void Gdk::DragContext::drop_finish | ( | bool | success, | 
| guint32 | time | ||
| ) | 
Ends the drag operation after a drop.
This function is called by the drag destination.

| time | The timestamp for this operation. | 
| void Gdk::DragContext::drop_reply | ( | bool | ok, |

Accepts or rejects a drop.
This function is called by the drag destination in response to a drop initiated by the drag source.

| DragProtocol* | protocol | ||
| ) | const | 
Finds the destination window and DND protocol to use at the given pointer position.
This function is called by the drag source to obtain the dest_window and protocol parameters for gdk_drag_motion().
| drag_window | A window which may be at the pointer position, but should be ignored, since it is put up by the drag source as an icon. | 
| screen | The screen where the destination window is sought. |
