Title Body

If a selected index on a JList is clicked, I want it to de-select. In other words, clicking on the indices actually toggles their selection. Didn't look like this was supported, so I tried list.addMouseListener(new MouseAdapter() { public void mousePressed(MouseEvent evt) { java.awt.Point point = evt.getPoint(); int index = list.locationToIndex(point); if (list.isSelectedIndex(index)) list.removeSelectionInterval(index, index); } }); The problem here is that this is being invoked after JList has already acted on the mouse event, so it deselects everything. So then I tried removing all of JList's MouseListeners, adding my own, and then adding all of the default listeners back. That didn't work, since JList would reselect the index after I had deselected it. Anyway, what I eventually came up with is MouseListener[] mls = list.getMouseListeners(); for (MouseListener ml : mls) list.removeMouseListener(ml); list.addMouseListener(new MouseAdapter() { public void mousePressed(MouseEvent evt) { java.awt.Point point = evt.getPoint(); final int index = list.locationToIndex(point); if (list.isSelectedIndex(index)) SwingUtilities.invokeLater(new Runnable() { public void run() { list.removeSelectionInterval(index, index); } }); } }); for (MouseListener ml : mls) list.addMouseListener(ml); ... and that works. But I don't like it. Is there a better way?
