I'm simply trying to get the size of a composite. I tried getBounds(),
getClientArea() and getSize() but all of their ints (eg rect.width)
returns 0. Does anyone know what I'm doing wrong?

Thanks in advance.

Hi Karei,

this depends on when you are calling these functions. If you call them
before the shell is layouted, you get 0. You can only make use of these
functions when the widgets are layouted.

Hope that helped,
Friederich

give ComputeSize a try: composite.computeSize(SWT.DEFAULT, SWT.DEFAULT)

Calling computeSize(SWT.DEFAULT, SWT.DEFAULT) does not give you the current
size. It gives you the preferred size of the widget. Depending on your
layout, this can be quite different from the size of the widget.

If you want to do something when the widget changes size, you should add a
Resize listener (addControlListener() and handle controlResized).
