i'm fairly new to swing, coming from jee.

i have a group of jradiobuttonmenuitem (s). when i select one, the actionPerformed method is always getting called. how do i only call the actionPerformed when it's first selcted.? right now i'm controling it by disabling the selected item, but that doesn't seem ideal.

By design (and thankfully consistently), the actionPerformed() method will be called each time the menu item is selected. What the actionPerformed method DOES when called is under your program's control. What you're trying to do is not completely clear, but you could restrict what the actionPerformed() method does by determining if the menu item is already selected by using the isSelected() method and acting accordingly, OR if you mean that the menu item is only to be selected once, then it seems appropriate that it WOULD be disabled after being selected once. There are many other possibilities, but what I've suggested should suffice until you more completely describe what you're trying to do.

you might be better off using an ItemListener

also, does it need to be static?
