XmDataFieldPaste man page
XmDataFieldPaste — A DataField function that inserts the clipboard selection
#include <Xm/DataF.h> Boolean XmDataFieldPaste( Widget widget);
XmDataFieldPaste inserts the clipboard selection at the insertion cursor of the destination widget. If XmNpendingDelete is True and the insertion cursor is inside the current selection, the clipboard selection replaces the selected text.
This routine calls the widget's XmNvalueChangedCallback and verification callbacks, either XmNmodifyVerifyCallback or XmNmodifyVerifyCallbackWcs, or both. If both verification callback lists are registered, the procedures of the XmNmodifyVerifyCallback list are executed first and the resulting data is passed to the XmNmodifyVerifyCallbackWcs callbacks.
This routine calls the widget's XmNdestinationCallback procedures with the selection member of the XmDestinationCallbackStruct set to CLIPBOARD and with the operation member set to XmCOPY. If the XmNcursorPosition resource is greater than or is the same value as the position where the selection is to be inserted, the XmNmotionVerifyCallback is called.
Specifies the DataField widget ID.

This function returns False if no transfers take place. Otherwise, it returns True.
