Subscribe to Mac OS keypress event

[felli]

thanks for the feedback ChrisW67. I thought maybe the CocoaNativeEventFilter::nativeEventFilter() was implemented <Appkit.h>, updated that and getting other compile errors now...

But my main question is how I can detect keypress events when my application is not in focus, is this possible with Qt?

thank you

It is not really a Qt question: Qt deals with the key presses the operating system sends it when it has focus. The question is whether the OS gives you a way to intercept key presses regardless of where they would naturally flow.

NSEvent addGlobalMonitorForEvents() looks promising to turn on a capture:

Exactly how you access this in your C++ code is not something I am familiar with although I expect that the resulting events should be seen in the Qt event filter.

Thank you ChrisW67, just the answer I needed. I will look into that.
