java - Background image on JFrame -


this question has answer here:

i begin in java programming language. make jframe , put background image on , above jframe, insert widgets : jtextarea , jbutton ... can not overlap. here code :

public void go() {     cadre = new jframe("premiere feneêtre");     cadre.setdefaultcloseoperation(windowconstants.exit_on_close);     cadre.setsize(600, 600);     cadre.setvisible(true);`      borderlayout agencement = new borderlayout();     jpanel arriereplan = new jpanel(agencement);     arriereplan.setborder(borderfactory.createemptyborder(10, 10, 10, 10));      box boiteaboutons = new box(boxlayout.page_axis);     boiteaboutons.setsize(150,150);     boiteaboutons.setopaque(false);     //boiteaboutons.setbackground(color.yellow);     b1 = new jbutton("bouton 1");     b1.addactionlistener(this);     b2 = new jbutton("bouton 2");     b2.addactionlistener(this);     b3 = new jbutton("bouton 3");     boiteaboutons.add(b1);     boiteaboutons.add(b2);     boiteaboutons.add(b3);     zonetexte = new jtextarea();      panneau p1 = new panneau();     arriereplan.add(borderlayout.south, boiteaboutons);     arriereplan.add(borderlayout.north,zonetexte);      cadre.getcontentpane().add(p1);     cadre.getcontentpane().add(arriereplan);  }  public class panneau extends jpanel {     public void paintcomponent(graphics g){         try {             image img = imageio.read(new file("c:/users/........png"));             //g.drawimage(img, 10, 10, this);             g.drawimage(img, 10, 10, this.getwidth(), this.getheight(), this);         } catch (ioexception e) {             e.printstacktrace();         }     } }

i've read several things here regarding problem encounter, nothing helped me .

thank sorry bad english

cadre.getcontentpane().add(p1); cadre.getcontentpane().add(arriereplan);

you can't add multiple component center of borderlayout.

instead want add component image panel:

panneau p1 = new panneau(); p1.setlayout( new borderlayout() ); p1.add(boiteaboutons, borderlayout.south); p1.add(zonetexte, borderlayout.north); cadre.add(p1);
