SWT repaint problem

[jan dressen]

i have a strange problem in SWT:

when I dispose some widgets and place new widgets on a composite then the newly created widget is not visible. an example is attached in the screenshot on the left side of the picture.
BUT: at the moment I resize my screen, suddenly the control pops-up. as you can see on the right side of the screen.

any idea why this happens, and how i can fix it?

In Swing you need to call repaint() and/or revalidate() after you change the component hierarchy. It wouldn't surprise me if the was necessary in SWT.

I tried calling redraw and update, but that doesn't fix it. repaint/revalidate is not available in SWT

but thanks anyway

I found the solution myself. It seems you have to call the layout(true, true) method on the composite containing your control. that makes it repaint its children

I knew it was something similar, I just didn't know the SWT equivalent.

thanks for pointing me in the correct direction...

You're welcome.
