How to update QApplication::desktop size after xrandr ?

[oncaphillis]

Hi,

I'm currently trying to make a X11 desktop manager (login screen) xrandr aware. The Application holds an QApplication: and draws into a rectangle defined by QApplication::desktop::size which starts up as being 1650x1025.

When I apply an "xrandr -l left" (rotate) to the X server the orientation of the desktop widget does not change automatically. How do I force a recalculation of the desktop size ?

Thanks 10^6

Connect to these signals, so you can react to desktop size changes:

• QDesktopWidget::resized
• QDesktopWidget::workAreaResized
