Global hotkey component

[regs]

I made a cross platform global hotkey component. For Windows, Unix X11 and macOS Cocoa/Carbon. macOS one using part of Carbon API, which is still legit. And as there is no global hotkey API for Cocoa yet. For Cocoa LCLWidgetType should be explicitly set to Cocoa.

It's very rigid - you can register with TShortCut, you can register directly with platform codes. You can use simple OnHotKey event, or more robust SC_HOTKEY message. There are couple of demos.

Here is for review

I didn't know there is very specific forum for this. So probably better to move there.

But does it work with every widgetset? For example, in QT* I used the QT library events hooks. See https://github.com/salvadorbs/AsuiteComps/blob/5fae32f167fbbf019085396da67766fe4992ae34/library/platform/unix/Hotkeys.Manager.Platform.pas#L574

He is hooking x11 directly, so should work theoretically for all widgetsets under x11 (just an fish eye in sources).

I saw it too. I don't have an updated and working linux installation, for what I was asking, otherwise I would have tried directly.

It doesn't rely on any widgetset for Unix. Tested GTK2, GTK3, Qt5, Qt6. Should work regardless of widgetset. Should also work not just on Linux, but any Unix with X11. I didn't try FreeBSD though.
