[Interest] Qt/Mac : text input in dialogs posted by LSUIElement apps ("agents")?

[René J. V. Bertin]

To answer my own question:

- this is a traditional, unbundled application (KIO's kiod5); I set LSUIElement 
programmatically
- in a comparable application (kwalletd5) that uses the same password dialog 
class this is enough
- in kiod5 I need to confirm the "agent" nature by calling [NSApp 
setActivationPolicy:NSApplicationActivationPolicyAccessory] just before calling 
QApplication::exec().

Apparently something between my the creation of the QApplication instance (= 
after setting LSUIElement) and QApplication::exec() does something that confuses 
the OS. [NSApp activationPolicy] still returns 
NSApplicationActivationPolicyAccessory so there's something wonky going on here.
