Select a Line with the Mouse

[JThornton]

How do you select a line drawn with a Qpen with the mouse and change the color. Also how do you get the coordinates of the line? And is is possible to select the end point of a line with the mouse?

@JThornton What you describe sounds like you rather should use Qt Graphics View Framework: https://doc.qt.io/qt-5/graphicsview.html
https://doc.qt.io/qt-5/qgraphicsscene.html

What you draw with QPainter is just a bunch of pixels - you would have to implement everything by yourself.

Thanks, I'm slowly sorting this out and that information is very helpful.
