How to lock screen Orientation(Windows) in QML 2 ?

Hello, I need to lock the orientation of my app but i am not finding any function to set the same. I am running the app in Microsoft Surface 3 and using QT 5.9.1. Please suggest.

I got to know that there is no such API to set Screen orientation in QT for windows and thus I used windows API for locking app Orientation, following is the code :

Just copy paste below code in main.cpp:

#include <Windows.h>

typedef enum ORIENTATION_PREFERENCE {
    
    ORIENTATION_PREFERENCE_NONE              = 0x0,
    
    ORIENTATION_PREFERENCE_LANDSCAPE         = 0x1,
    
    ORIENTATION_PREFERENCE_PORTRAIT          = 0x2,
    
    ORIENTATION_PREFERENCE_LANDSCAPE_FLIPPED = 0x4,
    
    ORIENTATION_PREFERENCE_PORTRAIT_FLIPPED  = 0x8
} ORIENTATION_PREFERENCE;

typedef BOOL (WINAPI *pSDARP)(ORIENTATION_PREFERENCE orientation);

pSDARP pARP;
pARP = (pSDARP) GetProcAddress( GetModuleHandle(TEXT("user32.dll")),  "SetDisplayAutoRotationPreferences");

if( pARP ){
    
    pARP( (ORIENTATION_PREFERENCE)(ORIENTATION_PREFERENCE_LANDSCAPE | ORIENTATION_PREFERENCE_LANDSCAPE_FLIPPED ) );
}
