Java自定义工具提示以最小化按钮

Question

I am creating a JFrame in the following way.

    JFrame f=new JFrame("Title");
    f.setUndecorated(true);
    f.getRootPane().setWindowDecorationStyle(JRootPane.FRAME);

However, I am trying to display a custom tooltip text for the JFrame (by default it shows "Iconify"). Please help me out.

Thanks !

Answer 1

One way add some panel to frame with tooltip you needed:

JPanel panel = new JPanel();
panel.setToolTipText("Message");
frame.add(panel, BorderLayout.CENTER);

Another way if you have custom minimize button:

JButton button = new JButton() {
  public JToolTip createToolTip() {
    JToolTip tip = super.createToolTip();
    tip.setBackground(Color.YELLOW);
    tip.setForeground(Color.RED);
    return tip;
  }

If you want to change text of minimize button in L&F, you can set InternalFrameTitlePane.minimizeButtonText value if UIDefaults .

UIManager.getDefaults().put("InternalFrameTitlePane.minimizeButtonText", "my text");

It can be used as a solution if you definitely know which L&F your application will use.
