[maemo-developers] How to switch an app to portrait mode (Qt)? Xrandr?

[From: Martin Grimme]

Hi,

the correct way (if the toolkit doesn't support hildon rotation) is to
use the X-Atoms

_HILDON_PORTRAIT_MODE_SUPPORT

and

_HILDON_PORTRAIT_MODE_REQUEST

(CARDINAL, 32bit, value either "1" or "0")

The SUPPORT atom is always needed on a window that allows portrait
mode. The device immediately switches back to landscape mode once it
opens a window without the SUPPORT atom.
The REQUEST atom requests portrait mode. The device remains in
portrait mode as long as the requesting window is visible and no
dialog windows above it lack the SUPPORT atom.
