Filter hotkeys for specific windows

[obraunsdorf]

Is it possible to only register hotkeys for specific windows? The parameter HWND Window's API Function RegisterHotKeys (https://docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-registerhotkey) seems to implement this functionality.
How would someone use winapi-easy best to get a HWND to the processes main window and pass it to RegisterHotKeys?

Thanks for your help!

It surely should be possible, but not with RegisterHotkey. According to the docs, passing a window handle would only mean that the associated window would receive the messages, nothing more. The hotkeys would still be global.
So, implementing this would require other functions from the Windows API, something which I haven't looked into yet.

Constructing / getting a window can already be done with winapi-easy, though I consider the API for this highly experimental still. But you can take a look at the new_window and get_window_infos examples.
