A pointer to a resource record, or NULL if no resource is found.
my_label_setcolor( PtWidget_t *widget, PgColor_t color ) { const PtResourceRec_t *res_rec; PtArg_t argt; PtSetArg( &argt, Pt_ARG_COLOR, color, 0 ); res_rec = PtFindResource( Pt_ARG_COLOR, PtLabel->wclass ); PtSetValue( widget, res_rec, &argt ); }
