I've a qt 5.5 application working on one part of a monitor displaying it's user interface. A different application does this for the rest of the screen. My question is: does a practical solution exists to display a transparent widget above the second applications screen space to have complete input focus for the entire screen and forward all input actions relevant to second application? (which will be rendered always behind that widget).
The second application is not a qt but WinApi application. Is it possible to filter input events (mouse, keyboard, etc) an send a subset to a different process in this constellation? Or when making this application a qt application?
Thank you!
