intercepting keyboard shortcuts in an app

Skaperen · 11-19-2020, 01:12 PM

i am running Xubuntu 18.04.5 with a keyboard shortcut set to have the PrtSc key run a program that captures a screenshot. i ran across an app that is reacting to that. i have a text input open in an app named "Gramps" (genealogy software) to type in the name of a new family tree. then i press PrtSc. it closes the input and sets up the default name.

i thought a shortcut key press would not be received by anything else. how can it be doing this? the app runs in Python3.

One distro I had, print screen would result in a small widget or other which popped up and allowed me to open a more formal viewer or editor, or just open the file location where the screenshot was stored. I sort of felt that was a good/normal behavior. I guess it wasn't necessarily a whole app, nor one which specifically required python, but instead it was part of the window manager I was using.

it could have invoked some executable that did both, or one that invoked something to do one of those and did the other itself, or one that invoked something for both.

in my case, it is my own code (written in Python3) that invokes a binary executable to get the results after it determines the name to give it, creates the directory it goes in, and changes to it. i can't find any messaging in that binary.
