Get screen coordinates in Qt

Comments

Didn't work properly with Qt 4.7.3 and N8. First time availableGeometry was ok, but after screen orientation change it doesn't give full screen coordinates anymore but QRect(0,92 360x487).

If this is a problem with the generic API can you please raise a qt defect: https://bugreports.qt-project.org/secure/Dashboard.jspa , pointing them to this example.

This code example shows how to get screen coordinates and screen size in a Qt application. The API QDesktopWidget::screenGeometry() returns the application rect (screen size of device) and API QDesktopWidget::availableGeometry() returns client rect (screen size minus status pane). It is useful in UI applications that do not use layout managers by implementing virtual QWidget::resizeEvent().
