I'm trying to update my application's toolbar so that it will automatically wrap to
use multiple rows for the buttons if the width of the application session window
becomes too narrow to show them all in a single row. The following testcase represents
what I'm trying to do. Can anyone get this changed so the height of the toolbar area
increases once the FlowLayout manager wraps to use multiple rows? I can see that the
wrapping is occuring, but the toolbar height doesn't change to accomodate the change
in the number of rows used by the toolbar's FlowLayout manager.
Thanks,
John (using 1.3.1)

});
Container c = getContentPane();
c.setLayout(new BorderLayout());
JToolBar tbar = new JToolBar();
tbar.setFloatable(false);
tbar.setLayout(new FlowLayout(FlowLayout.LEFT));
for (int i=1; i <= 15; i++) {
tbar.add(new JButton("Btn"+i));
}
c.add(tbar, BorderLayout.NORTH);
String s = "<html>This is the main<br>" +
"content area of the <br>" +
"application";
c.add(new JLabel(s), BorderLayout.CENTER);
pack();
setVisible(true);
}
}
