Java2D graphics question ?

Question

hi,
i had to tell that i have absolutely no experience with 2D features, and i would like to embellish my interface without having to read a lot of docs and tutorial, so my question is simple for swing's guru
I would like to apply the GradiantPaint(say form blue to white) to the backgournd color of a
JPanel object, can anyone tell me how to do it ?
thanks for your help

Answer 1

I have never tried this so i cannot tell you for definate extend JPanel similar to this and use JPanelGrad in the exact same way you would JPanel
public class JPanelGrad extends JPanel
  GradientPaint gp;
  public JPanelGrad(GradientPaint gp)
    super();
    this.gp=gp;
  public JPanelGrad(GradientPaint gp, LayoutManager layout, boolean isDoubleBuffered)
    super(layout, isDoubleBuffered);
    this.gp=gp;
  public void paint(Graphics _g)
    super(_g);//this statment will slow down painting and i think it is will make no difference to remove it...
                       //i think that in JPanel it simply calls paintComponent(g); paintBorder(g); paintChildren(g);
                       //try it both ways - preferablely remove it
    Graphics2D g=(Graphics2D)_g;
    g.fill(new Rectangle(0, 0, getWidth(), getHeight()));
    g.setPaint(gp);
    paintComponent(g);
    paintBorder(g);
    paintChildren(g);
                  //these three methods r to be in this order;
JPanelGrad panel=new JPanelGrad(new GradientPaint(0, 0, Color.blue, 10, 0, Color.white));
Simple as. Bamkin
