Emulator in landscape mode is messy

Platform Development

After struggling to get emulator to run in landscape mode, I’m faced with a few problems, the first one is an error given in console(same error twice);

[W] unknown:11 - file:///usr/lib/qt5/qml/Sailfish/Silica/private/CoverWindow.qml:11: ReferenceError: 
Config is not defined
[W] unknown:11 - file:///usr/lib/qt5/qml/Sailfish/Silica/private/CoverWindow.qml:11: ReferenceError: 
Config is not defined

When the emulator is ready, this is how it looks;

App starting to install on emulator;

Wallpaper grinning through the app;

Mitigated temporarily by applying a background color in my app;

The general performance in landscape (probably portrait too) is abysmally slow, dropping frames like mad, any animations running are so clunky, it’s basically unusable.

I have some good news for you: I was pretty much able to reproduce this with the 4.4.0.58 emulator. On our current development version, which will become the 4.5.0 emulator, I wasn’t able to reproduce. So to me it seems that whatever was causing the messiness has been fixed.

Good to know, thanks @vige.

Still seeing the same error in 4.6.0.11;

Is this a setting you modify before booting or can you somehow trigger a screen rotation while the emulator is running?

I would like to test landscape layouts and the switches between layout but have not been able to find where to trigger such a thing.

In Qt creator, using tools - sailfishos - emulator mode you can set the orientation to portrait or landscape.
In your app you can use a function that changes the orientation, e.g. SwitchOrientation()

function switchOrientation() { if (orientation === Orientation.Landscape) { allowedOrientations = Orientation.Portrait} else allowedOrientations = Orientation.Landscape }

Thanks I had not found the emulator mode menu so far, it would be nice if the emulator could switch mode without rebooting but I guess that would be pretty complicated to implement.

Still the same error with latest emulator 4.6.0.13
