ChangeListener called twice

[riches85]

I have a ChangeListener registered with a JMenuITem that I want to fire whenever a menuItem gets selected but two events are fired. One is fired when the menuItem is selected and one when the menuItem is deselected. Is there a way to only have it fire once when the munuItem is selected? Thanks

There's no way to make it fire the event only when the menu item is selected, but you have the following option:
In the stateChanged() method implemented in the ChangeListener object sent as a parameter to yourMenuItem.addChangeListener() method, check for that menu item's isArmed() and isDisplayable() values:

JMenuItem item = new JMenuItem("item");
item.addChangeListener(new ChangeListener() {
	public void stateChanged(ChangeEvent e) {
		JMenuItem mitem = (JMenuItem) e.getSource();
		if (mitem.isDisplayable() && mitem.isArmed()) {
			System.out.println("ding!");
		}
	}
});

Good luck ;-)
