Ok.. so it seems you can't set the size of a composite within a shell.. then set a layout manager on this composite (to organise widgets within the composite itself)?

It's giving me a headache..

I don't get why that doesn't work.

Matt,

You need to invoke layout() on the Composite, example snippet is below:

public static void main(String[] args) {
Display display = new Display ();
Shell shell = new Shell (display);
shell.setBounds (10,10,200,200);
final Composite composite = new Composite(shell, SWT.BORDER);
composite.setBounds(10,10,180,150);
Button b1 = new Button(composite, SWT.PUSH);
b1.setText("Push");
b1.addListener(SWT.Selection, new Listener() {
public void handleEvent(Event event) {
composite.setLayout(new GridLayout(2, true));
composite.layout(); // <--------
}
});
b1.setBounds(10,20,30,40);
new Button(composite, SWT.PUSH).setBounds(50,60,70,80);
shell.open ();
while (!shell.isDisposed ()){
if (!display.readAndDispatch ()) display.sleep ();
}
display.dispose ();
}

I'm sure I tried that, but I'm unsure..
Though I am setting the layout before I add items to the composite.. I will try it that way tomorrow morning then, & will post results :)

Thanks.
