Call a button "invokeAction" from Menu item

Hi,

 

If I have a button and have written some code for it's invokeAction method, is it possible to call that button's invokeAction method from a menu item?

 

I suppose I could just copy the code for this button and add it to the menu; I'm really just wondering if there's an easier way.

 

(Sorry if this has already been covered in this forum, I'm not quite sure of the kinds of search terms I would use to find a solution to my question.)

 

Thanks!

Re: Call a button "invokeAction" from Menu item

invokeAction is protected, so you can't call it directly. You can play games like deriving a subclass with invokeAction made public. But it's usually simpler to just have the button's listener and the menu item's listener invoke a common method. That's easy and obvious if the listeners are in the same code module and a little more complicated if they're not, of course.  But, in general duplicate code is a Bad Idea, and it's even worse if the duplicates are in different modules.

Gosh--it makes total sense to have the "button's listener and the menu item's listener invoke a common method."

 

Thanks jMarc!
