SWT event handling

[Peter Jersey]

Hi all,

I have a question about good design in SWT.

Given an ApplicationWindow that has two Components, X and Y:

class ApplicationWindow {
  protected Control createContents(Composite parent) {
    X x = new X(this);
    Y y = new Y(this);
  }
}
class X extends Composite {
  public X(Composite parent) {
    super(parent, SWT.NONE);
    final Button button_X = new Button(this, SWT.NONE);
  }
}
class Y extends Composite {
  public Y(Composite parent) {
    super(parent, SWT.NONE);
    final Button button_Y = new Button(this, SWT.NONE);
  }
}

I want to attach a listener to button_X that reacts to mouse clicks. I want to change the label of BOTH buttons, button_X and button_Y when button_X is clicked. To change the laben of button_X in reaction to the mouse click, it is clear that I need to do something like this:

button_X.addListener(SWT.MouseDown, new SimpleListener("Display mouse down Listener"));
addListener (int eventType, Listener handler)

button_X.addMouseListener(new MouseListener() {
public void mouseDown(MouseEvent e) {
button_X.setText("Mouse Button Down");
}
}

But how can I modify properties on button_Y at the same time? I could work with static methods to get a reference to the button, but is this really the way people do this? I suppose there is a more elegant and API conforming solution.


Thanks for any hints!

Anyone? This ain't such a hard question, is it?

We don't have that many SWT users anymore, I fear...

[Peter Jersey]

but why that? Have I missed the next big step after SWT/JFace?

I honestly cannot tell you. All I know is that most threads here are about Swing problems.
