action info

[Peter van der Winkel]

I got something like this:

- JButton(name=b1, onAction=myMethod, ...)

Is it possible to give some extra information to the specified onAction
method?

May be:

- JButton(name=b1, onAction=myMethod,
actionArguments="string1,string2" , ...)

and the Java method should be:

public void myMethod(Object[] arguments)

Not at this point. The onAction (and other on* event listeners) were
more thought to be a signal/slot type approach, where you send a
"onAction" signal
and I try to find the slow it should go to, depending on method names
and signatures on the Java side.

But this has come up before, so it is probably a good enhancement. Pls
add an enhancement request for it.
However, I would only support hard-coded values, I don't want to get
into the complexity of passing expressions into the arguments.
Also, it would probably be in the event listener itself, since you can
pass multiple ones, e.g.:

JButton(onAction=[$confirm,save("Some hardcoded param"),cleanup])

My take on this, is that if you're getting that complicated, you
should configure the JButton in Java rather than in yaml. It's really
very easy and this seems like unnecessary baggage to impose upon
JavaBuilders. You should either use a no-args method or a String equal
to a fixed action name, or program what you want yourself.

Something like the following would work:


class MyClass {

...

public void init() { // some initialization method where you setup
things
((JButton)buildResult.get("buttonName")).setAction(new
AbstractAction()
{
@Override public void actionPerformed(ActionEvent event) {
myMethod(33, "Napoleon");
}
}
);

public void myMethod(int n, String who)
{
....
}
}

You have a valid point too. Either way, I was not planning to look
into this prior to 1.0.
