I am learning some principles of X, and I want to know how to listen selection event of Xlib and transfer text selected of the application.
I read the mannul from https://tronche.com/gui/x/xlib/ https://github.com/python-xlib/python-xlib and as a newbie that is too complex for me.
I have no plan to try gtk+ and Qt and others which lead to extra dependencies.
so please give me some advice or a demo if could, thanks.
