I would like to be able to have a JSplitPane call
its resetToPreferredSizes() method if the user double clicks on the divider. This feature could be an option, like
setOneTouchExpandable().

I tried adding a MouseAdapter to implement this feature, but I ran into a couple of problems:

1) If I add the MouseAdapter to the JSplitPane,
   the adapter only responds to a very narrow
   portion of the divider.

2) If I add the MouseAdapter to the divider
   (to which there is no convenient access)
   I am no longer able to drag the divider.

I used the following code to add the adapter to
the divider.

try {
  Component divider =
    ((java.awt.swing.plaf.basic.BasicSplitPaneUI)
    fSplitPane.getUI()).getDivider();
      
  divider.addMouseListener (new MouseAdapter() {
    public void mouseClicked (MouseEvent event)
    {
      if (event.getClickCount() == 2) {
        fSplitPane.resetToPreferredSizes();
        repaint(); // This shouldn't be necessary!
      } // if
    } // mouseClicked
  });
} catch (ClassCastException e) {}
