question: this function fills a rectangle with a vertical gradient . this implementation does not use the gradient mechanism based on background patterns since they do not work stable on all systems . concode_field_sep PlaceHolder placeHolder concode_field_sep void fillVerticalGradientRoundedRectangle concode_elem_sep Color mixColor
target: void function ( Graphics arg0 , Rectangle arg1 , Color arg2 , Color arg3 ) { arg0 . pushState ( ) ; arg0 . setForegroundColor ( arg3 ) ; arg0 . setBackgroundColor ( arg2 ) ; arg0 . fillGradient ( arg1 . x , arg1 . y , arg1 . width , arg1 . height , true ) ; arg0 . popState ( ) ; }
