Global hotkey
« on: March 31, 2020, 10:32:25 am »
I'd like to register a hotkey (e.g cmd+alt+Q)" that will do a specific action in my application when pressed, even when my app isn't in the foreground.
Is that possible? I checked out getKeyState but that only gets modifiers

I managed to get it to work with Install(Application)EventHandler, and RegisterEventHotkey

I may be wrong, but isn't RegisterEventHotkey from the 32 bit Carbon framework? In which case it will not work after Mojave...

I'm on catalina and it still works. It's one of the functions that they kept functional in 64-bit
