Get screen orientation before any form created

vlad2048

Hi All

Is there any way to get current screen orientation before any form or widget created (i.e. in main.cpp after the "QApplication a(argc, argv);" line)? This is required because of the application behaves in a strange manner durring the start-up in this case: if a user clicked application icon in the portrait mode and turned the device into landscape mode, the application will still run in a portrait mode (I mean the widget sizes would be as in the portrait mode but the screen is in landscape mode, and as a result of incorrect application visualization, and this is until next orientation change).

Thanks ahead

Please also note that my application is running in full screen mode (showFullScreen() is called).

One idea: you can get the "desktopWidget":http://doc.trolltech.com/4.7//qapplication.html#desktop for the application and check it's size....

You could also check if QOrientationReading is useful, but haven't used it myself

Just thinking out loud:

The orientation sensor will give you the physical orientation of the device. Depending on the device you may want to take other sensors into consideration. For example the auto-rotation on the n900 is disabled when the keyboard is open.

I can't wait to experiment with it. I have used the dbus signals on the n900 to detect the device changing orientation but this would be The Qt way.
