Problems_using_JSplitPane

Question

using JSplitPane, how can I do to avoid that one of the two panel covers the other panel totally? For example, considering the example SplitPaneDemo in the JavaTutorial, how can I do to avoid that the list of files .gif covers totally the panel that shows photos when I expand it?
if the problem isn't clear, please tell me!
thanks in advance!!!!!

In the future, Swing related questions should be posted in the Swing forum.
The following code is from the demo program:
        splitPane.setOneTouchExpandable(true);
        splitPane.setDividerLocation(150);
        //Provide minimum sizes for the two components in the split pane.
        Dimension minimumSize = new Dimension(100, 50);
        listScrollPane.setMinimumSize(minimumSize);
        pictureScrollPane.setMinimumSize(minimumSize);When you drag the divider with the mouse, the minimum size is respected. So you could turn the one touch expandable off.
If you feel you need one touch expandable then you could add a PropertyChangeListener to check for a change in divider location. When the location is below or above a certain value, you reset it to your minimum value.
public void propertyChange(PropertyChangeEvent e)
     if ("dividerLocation".equals(e.getPropertyName()))
          JSplitPane source = (JSplitPane)e.getSource();
          int location = ((Integer)e.getNewValue()).intValue();
          if (location < someValue)
               source.setDividerLocation( someValue );
}
