JButton : Background and Text

[Keys]

Hello,

I want to create a JButton with an image in background and a dynamic text.

I create my own derived JButton to implement paintComponent() method.
So my background is ok but when I try to use setText() I can't see my text...

Then I try to implement drawString() method in my button. With this method I can see my text but my background disappear !

Please can you tell me how to fix that and create button with background and text ?

Thank you.

There's no need to reinvent the wheel. JButton has setIcon and setText methods (also setRolloverIcon / setPressedIcon / serDisabledIcon ... did I miss any?

You can create an implementation of Icon that returns 0 for its width and height (thus ensuring that the button doesn't reserve space for the Icon) and paints the entire background (using getWidth() / getHeight() of the Component parameter to paintIcon. Something like (mayhave typos)

class BackgrouindIcon implements Icon {

  @Override
  public int getIconWidth() {
    return 0;
  }

  @Override
  public int getIconHeight() {
    return 0;
  }

  @Override
  public void paintIcon(Component c, Graphics g, int x, int y) {
    g.setColor(Color.ORANGE);
    g.fillRect(0, 0, c.getWidth(), c.getHeight());
  }
}

This may displace the button's text off-center due to the text-icon gap. You can fine-tune this either by setIconTextGap(0) or by setting the horizontal and vertical text position to CENTER.
