KCGDisplaySetMainFlag not firing

  • Thread-topic: KCGDisplaySetMainFlag not firing

I have a MBP17 and a 23" Cinema. The Cinema is the main display.

I am using:

void DisplayReconfigurationCallBack (CGDirectDisplayID display,
CGDisplayChangeSummaryFlags flags, void *userInfo)

When I remove the Cinema I get:

KCGDisplayRemoveFlag
kCGDisplaySetMainFlag   // main is now set to the internal 17"

When I re-attach the Cinema I get:

KCGDisplayAddFlag

But do not get kCGDisplaySetMainFlag even though the main display is reset
to the Cinema.

Is this expected behavior? It seems odd.

Thanks,

Trygve
