Hi, all
Well, I'm just getting back into java after about a 15 year hiatus. I
did a bunch of it back then, both SE and EE, but then got off on other
projects.
Now I want to get my fingers back into it and see massive changes. It's
going to take a log of getting used to.
For instance, I was looking at a game I wrote back then (nothing fancy -
just something to play with). With Swing it's very easy to change the
look of buttons by loading a new image, i.d. when the player presses the
button. It seems with fx the only way you can change the button when
it's pressed/not pressed is via css. While I guess there are advantages
to doing it this way, I haven't seen them yet. And I'd rather be able
to control the button looks myself.
So my first question is - are there events I can intercept to tell when
the button is pressed and when it is released? All I see so far is the
ACTION event.
And I'll also ask a short question with I suspect long (and very
subjective) answers. Which IDE do you like for developing Java apps,
and why? Most will be standalone gui apps for now. And please - I know
which IDE can be almost a religious discussion - let's not commit any
sins against other IDE's :)
Swing, and JavaFX classes that work alike.

btn.addActionListener(new ActionListener() {

System.out.println("Button Clicked");
}

add(btn);

Jeff, all you're doing is further making a fool of yourself. And after
