Answer 1

you can count screens with QDesktopWidget::screenCount() (Qt 4.6) and then travel through all screens and do QPixmap::grabWindow(...)

About "desktop composed from 2 screens". It all depends if 2 screen is virtual (all screens treated as one screen) or not.

@Frerich Raabe: it works on Windows 7 as I'm using similar code to perform screen grab.
