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.
- Parameters
-
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.
- Parameters
-
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.
- Parameters
-
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.
- Parameters
-
success true
if the data was successfully received.time The timestamp for this operation.
void Gdk::DragContext::drop_reply | ( | bool | ok, |
guint32 | time | ||
) |
Accepts or rejects a drop.
This function is called by the drag destination in response to a drop initiated by the drag source.
- Parameters
-
ok true
if the drop is accepted.time The timestamp for this operation.
void Gdk::DragContext::find_window_for_screen | ( | const Glib::RefPtr< Window >& | drag_window, |
const Glib::RefPtr< Screen >& | screen, | ||
int | x_root, | ||
int | y_root, | ||
Glib::RefPtr< Window >& | dest_window, | ||
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().
- Parameters
-
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. x_root The x position of the pointer in root coordinates. y_root The y position of the pointer in root coordinates. dest_window Location to store the destination window in. protocol Location to store the DND protocol in.

bool Gdk::DragContext::get_is_source | ( | ) | const |
Discover whether the context is used on the source side.
- Returns
- true if the context is used on the source side.
DragProtocol Gdk::DragContext::get_protocol | ( | ) | const |
