swing - Java JButton not updating -

i have jbutton when call settext(), text not update. hover on button, updates. how can fix when call settext(), button updates? post methods edt takes it. goes in order :)

public void mouseclicked(mouseevent e) {//this differn't event. not executed clicking on same button. it's differn't one.             click(new point(e.getx() + gridscrollpaneviewport.getviewposition().x, e.gety() + gridscrollpaneviewport.getviewposition().y));         }  public void click(point point) {                 map.selectplot((plotgui) map.getcomponentat(point));             } public void selectplot(plotgui plot) {         chickentycoon.getinstance().getscreen().getplayingscreen().sidebar                 .setplot(plot);         selectedplot = plot;     }  public void setplot(plotgui plot) {         title.settext(plot.getname() + plot.getx() + plot.gety());         (component comp : stuffpanel.getcomponents()) {             stuffpanel.remove(comp);         }         (component comp : plot.getcomponentlist()) {             stuffpanel.add(comp);         }         update();     }  public void update() {         if (chickentycoon.getinstance().getscreen().getplayingscreen().map                 .getselectedplot() != null) {             chickentycoon.getinstance().getscreen().getplayingscreen().map                     .getselectedplot().update();         }     }  public void update() {         log.m("updating landgui");         ((cbutton) componentlist[0]).settext("buy $ "//i know casting cbutton, it's custom version of jbutton. tried jbutton , same thing happens.                 + ((land) parentplot).getpurchaseprice());     }

i fixed it. needed add repaint container button. simple that!

button.settext("some text"); buttoncontainer.repaint();
