Probably a weird question. I didn't find answers...
Could a "triple tap / middle mouse button" event trigger something that can be caught and hooked in OctoPrint ?
Goal : show/hide a Marlin UI overlay transparent window by triple tapping a touch display ; for the current project I call "The OctoPrinter"
(Marlin UI overlay low level code does work, but needs a GPIO hardware button)
Note : I now know how to capture and grab HID events at low level (file system), but not how to forward these events back to the window manager. And it would be silly to do so. And probably extremely difficult to do (the main reason I ask this question ).
Note2 : not a Python guy. Hardcore C/C++/Win32API guy inside. (this would be easy with Win32 ; pealse, no flame !)
