One problem, and maybe the main problem, is that Qt seems to incorrectly
rely on the OS view that is created when the app is created, but this
view doesn’t persist when airplay is engaged or when it is disengaged. I
think any of us could see this problem when you disable airplay
mirroring while running a Qt app and the app crashes.

This problem also appears to prevent Reflector 2 from showing the
mirrored view of the iPad app when running the Qt app, which I can only
interpret to mean that the Qt view is not complying with the OS’s
standardized view API. Reflector works fine when another app or
launchpad (desktop) is shown.

So there is some work to do here…I wish I was better with UIKit to
troubleshoot.

Patrick,

you have to setGeometry(QRect screenGeometry) explicitly.
screenGeometry should be queried from iOS directly, like this:

constCGRectr=[[UIScreenmainScreen]bounds];
returnQRect(0,0,r.size.width,r.size.height);


We had similar problem, black screen with AirPlay or with HDMI
dongle. This solved it for us.

Patrick,

you have to setGeometry(QRect screenGeometry) explicitly. screenGeometry should 
be queried from iOS directly, like this:

const CGRect r = [[UIScreen mainScreen] bounds];
return QRect(0, 0, r.size.width, r.size.height);


We had similar problem, black screen with AirPlay or with HDMI dongle. This 
solved it for us.
