#include Normal Xt includes
#include <IntrinsicP.h>
#include <CoreP.h>

	ExposeEvent event ;
	event->x = 0 ;
	event->y = 0 ;
	event->width = label->core.width ;
	event->height = label->core.height ;
	label->core.widget_class->core_class.expose(label,&event) ;
	XFlush(XtDisplay(label)) ;

I have never tried this, but It should work.
