A Gdk::DragContext holds information about a drag in progress.
It is used on both source and destination sides.
|
noexcept |
|
overridenoexcept |
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 | A 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.
success | true if the data was successfully received. |
time | The timestamp for this operation. |
void Gdk::DragContext::drop_reply | ( | bool | accepted, |
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.
accepted | true if the drop is accepted. |
time | The timestamp for this operation. |

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().
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. |
