How to lock screen orientation (Android&Qt5.1)

[zlutor]

Is there any solution for locking screen orientation to portrait mode?

Something equivalent to good old solution in main.cpp:

@QmlApplicationViewer viewer;
viewer.setOrientation(QmlApplicationViewer::ScreenOrientationLockPortrait);@

1 solution would be the android manifest.

just add android:screenOrientation="portrait" for the main activity

could you, please, alter my manifest file below?

This worked for me too, thanks.
Anyway it sounds strange to me that there is not something like:
@Window.setOrientation@
@Window.lockOrientation@
@Screen.setOrientation@
@Screen.lockOrientation@

ps. I use qt 5.4 :)

In case you need a function call to set orientation you can use the info in this post:
