Although it is backwards compatible in terms of compilability, it'll only do anything on Java 1.5.
Instead of instantiating JFileChooser, instantiate this deriving class:
public class MyFileChooser extends JFileChooser
{
public MyFileChooser()
{
JList list = findFileList(this);
for (MouseListener l : list.getMouseListeners())
{
if (l.getClass().getName().indexOf("FilePane") >= 0)
{
list.removeMouseListener(l);
list.addMouseListener(new MyMouseListener(l));
}
}
}
private JList findFileList(Component comp)
{
if (comp instanceof JList)
return (JList)comp;
if (comp instanceof Container)
{
for (Component child : ((Container)comp).getComponents())
{
JList list = findFileList(child);
if (list != null)
return list;
}
}
return null;
}
private class MyMouseListener extends MouseAdapter
{
MyMouseListener(MouseListener listenerChain)
{
m_listenerChain = listenerChain;
}
public void mouseClicked(MouseEvent event)
{
if (event.getClickCount() > 1)
m_listenerChain.mouseClicked(event);
}
private MouseListener m_listenerChain;
}
}
