Screen selection by mouse hold like in lightshot on Pyqt5?

Question

PyQt

I'm trying to make a program that will select the screen by pressing the LMB key into a rectangle, like in lightshot, and then take a screenshot of this selected area. We need a visualization of the selection.

Answer 1

Full screen window, transparent, remember the coordinates of the mouse click - the mouse coordinates of the end - take a screenshot, cut a piece according to the coordinates of the beginning and end
