item placed on the clipboard
int XmClipboardUndoCopy ( display, window)
Display * display;
deletes the last item placed on the clipboard if the
item was placed there by an application with the passed display
arguments. Any data item deleted from the clipboard by the
original call to XmClipboardCopy
is restored. If the display
IDs do not match the last copied item, no action is taken, and
this function has no effect.
- Specifies a pointer to the Display structure that was returned in a
previous call to XOpenDisplay or XtDisplay.
- Specifies the window ID of a widget that relates the application window to
the clipboard. The widget's window ID can be obtained through
XtWindow. The same application instance should pass the same window
ID to each clipboard function it calls.
- The function was successful.
- The function failed because the clipboard was locked by another
application. The application can continue to call the function again with
the same parameters until the lock goes away. This gives the application
the opportunity to ask if the user wants to keep trying or to give up on
