How to keep Metal L&F when dragging JToolBar

Question

In our aplication we use Metal L&F. We are using a floatable JToolBar; it happens that when doing the drag behavior it appears with the Windows L&F.

May anyone say me how to keep Metal L&F when dragging the JToolBar?

Thanks

P.D. Our JToolBar is within a JPanel container that user BorderLayout Layout Manager.

Maybe I explained badly my question. So I post an example taken from The Java Tutorials to give anyone an idea of what happens to my application.

If you execute the following code the main JFrame appears decorated with Ocean Theme; but when I drag the JToolBar its decorated is not Ocean. What can I do??.

Many thanks in advance

Answer 1

Looks like nowadays the toplevel container of the ripped of toolBar is of type JDialog, so you have the set the lafDecoration for that as well:

JFrame.setDefaultLookAndFeelDecorated(Boolean.TRUE);
JDialog.setDefaultLookAndFeelDecorated(true);

Works for jdk7 and vista, didn't test other environments.

Answer 2

I made a small project as you described:

public class LafTest
{
    public static void main(String[] args)
    {
        JFrame frame = new JFrame();
        frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);

        frame.setSize(500, 500);

        JPanel panel = new JPanel(new BorderLayout());
        JToolBar toolbar = new JToolBar();

        toolbar.add(new JButton("button1"));
        toolbar.add(new JButton("button2"));

        panel.add(toolbar, BorderLayout.PAGE_START);

        frame.add(panel);

        frame.setVisible(true);
    }
}

Works fine for me, all the time the JToolBar has Metal-LAF. (OS: Windows 7 x64, java version "1.7.0_09")

Please compare your code with this snippet. Propably you used the UIManager-class somewhere. If you still cannot fix this issue, you should post some of the used code and maybe some more details about your OS and the used Java version.
