Lock screen orientation

[patrikd]

Hi all,
is there a way to lock the screen to for all mobile devices to portrait mode only by code?
I found a solution for doing that on android with overriding the standard activity and add code
for a jni call. But I also need that on iOS.
I also tried:

QScreen* screen = QGuiApplication::primaryScreen();
    screen->setOrientationUpdateMask(Qt::PortraitOrientation);

QScreen* screen = QGuiApplication::primaryScreen();
    screen->setOrientationUpdateMask(Qt::PortraitOrientation);

To copy to clipboard, switch view to plain text mode 

but this seems to have no effect, screen is still rotating.
Any ideas?
Thx,
Patrik

Orientation update mask is only for limiting the orientation change signals to the ones you are interested in.

There might not be any Qt API right now to force a certain orientation, probably requiring native code.

Might make an interesting upstream contribution

ok, is than there a way on iOS to access the basic ui-controller like under android?
I found this for iOS:

@implementation UINavigationController (Rotation_IOS6)
 
-(BOOL)shouldAutorotate
{
    return UIInterfaceOrientationMaskPortrait;
}
 
-(NSUInteger)supportedInterfaceOrientations
{
  return UIInterfaceOrientationMaskPortrait;
}
 
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
 return UIInterfaceOrientationPortrait;
}
 
@end}

@implementation UINavigationController (Rotation_IOS6)

-(BOOL)shouldAutorotate
{
    return UIInterfaceOrientationMaskPortrait;
}

-(NSUInteger)supportedInterfaceOrientations
{
  return UIInterfaceOrientationMaskPortrait;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
 return UIInterfaceOrientationPortrait;
}

@end}

To copy to clipboard, switch view to plain text mode 

but for this I think I have to implement the UINavigationController. Has anyone done this?
best,
patrik
