[Java-gnome-developer] Question: Gtk+ images drawing using Cairo ? - Button.onClicked ?

[Goundy <go...@gm...>]

Hi everyone,

I just tried to draw some images using Cairo well it actually works !

But I've some conception problems. I'm developing a game that requires 
refreshing the game area each time  a command is received over network 
(Poker game).
At this moment, I do image printing in the ExposeEvent of a Image 
(GtkImage) just like the Afc example, but I really don't see how should 
I do to be able to draw at a given moment !
Any ideas about this ?

Second question (might be silly) but I really have no idea about it:
Say: Button btn = new Button("Do Something");
        btn.connect(new Button.Clicked(){
            @Override
            public void onClicked(Button arg0) {
                // Here I want to access some classes instances 
instantiated somewhere         
            }          
        });
What I want to do are things like:
- When  a button A is clicked: Send some data over some Socket descriptor
- When  a button B is clicked: Change some part of the GUI 
(redrawing,... etc)

But I've no idea on how to pass arguments to these events... any help?

Thank you.
Miloud Bel.
