events for jlist

[rmacnak]

I have a JList of objects, I know how to get an event of an item is
selected, but how do i receive an event if an item is double clicked?

thanks in advance

Try something like this:
jListFiles.addMouseListener(new java.awt.event.MouseAdapter() {
public void mouseClicked(java.awt.event.MouseEvent evt){
JList list = (JList)evt.getSource();
if (evt.getClickCount()==2) goButtonClicked(evt);
}
});

quoting from the JavaDoc

JList doesn't provide any special support for handling double or
triple (or N) mouse clicks however it's easy to handle them using a
MouseListener. Use the JList method locationToIndex() to determine
what cell was clicked. For example:

final JList list = new JList(dataModel);
MouseListener mouseListener = new MouseAdapter() {
public void mouseClicked(MouseEvent e) {
if (e.getClickCount() == 2) {
int index = list.locationToIndex(e.getPoint());
System.out.println("Double clicked on Item " + index);
}
}
};
list.addMouseListener(mouseListener);
