I am looking for the source for the SpinButton. I was expecting to find it at either https://pypi.org/project/wxPython or an old version at https://github.com/wxWidgets/wxPython-Classic, but am not finding a Python source named SpinButton at either place. Am I looking at the right stuff?
I’m doing it because I am considering a similar control but with different appearance and want to know how the keypress hold and timing and so forth are done. If there’s a way to extend that class, I’d like to understand that (I wouldn’t think so looking at the API).
Am I assuming correctly that these widgets are written in Python, or are they in some kind of Python-compliant C, some equivalent to the Java Native Interface for that language?
