How to make a button selected by default in JToolbar

Question

I created a small tool set which is composed of around 10 buttons. These buttons are added to a JToolBar. Currently, it puts a square around the first button by default; however, I would like a different button to be the default. How can I accomplish this? Below is an example of how I am adding the buttons. I have tried select.setSelected and a few other methods but haven't had any luck.

  JToolBar sideBar = new JToolBar();

  JButton select = new JButton(new ImageIcon("Media/select.png"));
  select.setBorderPainted(false);
  select.setContentAreaFilled(false);

  sideBar.add(select);

Here's an image of the current result:

current result - notice square on top left button

In the future, a print screen would be useful so we understand what the "square" you are seeing is (which in this case, I presume, is the "focus" square that Swing assigns) — CodeGuy, Apr 01 '13 at 00:08

If you know which button you want to be active, you can use

button.requestFocusInWindow();

You can also try to set the default button at the root pane, depending on the set up of your Swing elements.

rootPane.setDefaultButton(button);

And finally, there is a handy method called setFocusedPainted(false);

I tried this but I don't see any difference. The blue focus square is still staying around the first button. – Pedrom Apr 01 '13 at 00:33

-1, don't use requestFocus() (see the API for this method), use requestFocusInWindow(). – camickr Apr 01 '13 at 01:19
Sorry, I meant to put that! – CodeGuy Apr 01 '13 at 01:20
button.requestFocusInWindow(); did the trick, thank you very much everyone – Pedrom Apr 01 '13 at 01:25

You may want to set one button as the default button for the toolbar this way:

yourToolBar.getRootPane().setDefaultButton(okButton);

I often use the setDefaultButton method within Dialog boxes so the user can select the default button by pressing [Enter].

Thanks Thorn, this will be useful for the dialog boxes I have. – Pedrom Apr 01 '13 at 01:27
