Re: [platform-swt-dev] Skins support and changing colours


This is a Windows limitation.  No native application can change the background color of a button on Windows.

Thanks. It's too bad I'm not using win XP. I've seen it done

Doesn't seem work. I remember bring this topic up before.

I'm trying to avoid writing a button widget, but I'm not sure how I'd go
about getting a gc on a button.
From the snippets, this seems to be the only way I can change it.
   button.addPaintListener(new PaintListener()
     {
        public void paintControl(PaintEvent e)
        {
           
e.gc.setBackground(Display.getDefault().getSystemColor(SWT.COLOR_BLUE));
        }
     });

but it doesn't work, and the color still stays grey.
