Organizing Actions in a Swing Application?

Question

My current application has a JFrame with about 15 actions stored as fields within the JFrame. Each of the actions is an anonymous class and some of them are pretty long.

Answer 1

That's typically how I do it. Each action gets it's own class which has a reference to the "app" object so it can get to resources it needs. I usually have an action manager that holds all the actions so there's one place to access them as well as one place to update their enablement and stuff.

Eventually this also becomes unmanageable at which point you should start thinking about using an app framework like Eclipse RCP, the NetBeans framework, JIDE, etc. This is especially true if you want to support user-defined keymaps and stuff like that.
