Re: [JELLY] Key listeners

[Sean Ferguson]

I've tried, but writing a lot of Java code in Jelly doesn't seem to work 
out too well.  I get lots of parser errors, even though it's valid Java 
code.  I'll take a look at jexl, I haven't heard of that.

If I remember well jcomponent.getActionMap() gives you an object which 
you can enrich to put define new actions by their names (their "keys" in 
the swing's javadoc parlance). You then bind these names to keystrokes 
using jcomponent.getInputMap()...

Isn't it possible to do this in Jelly ?

 From looking at the ActionTag source code, I am confused as to how 
I'd "fiddle with the actionMap and keymap."  Perhaps you can clarify 
that for me?

Thanks

Sean,

I don't think KeyListeners are a good thing to use as they are very 
low-level (hence may turn-out slow in Jelly I would fear). But an 
action can be attached to any keypress for any Swing component. You 
just have to fiddle with the actionMap and keymap (with names in the 
middle).
