XmContainerCut — Container widget function to move items to the clipboard
#include <Xm/Container.h> Boolean XmContainerCut( Widget container, Time timestamp);
XmContainerCut cuts the primary selected items to the clipboard. This routine calls the XmNconvertCallback procedures, possibly multiple times, with the selection member of the XmConvertCallbackStruct set to CLIPBOARD and with the parm member set to XmMOVE. If the transfer is successful, this routine then calls the XmNconvertCallback procedures for the CLIPBOARD selection and the DELETE target.
Specifies the Container widget ID.
Specifies the server time at which to modify the selection value.
For a complete definition of Container and its associated resources, see XmContainer(3).
The function returns False in the following cases: if the primary selection is NULL, if the widget does not own the primary selection, or if the function is unable to gain ownership of the clipboard selection. Otherwise, it returns True.
