Python PyQt5 standard dialog box usage example, pythonpyqt5

This article describes how to use the Python PyQt5 standard dialog box. We will share this with you for your reference. The details are as follows:

Complete Qt standard dialog box, including QInputDialog, QColorDialog, QFontDialog, QMessageBox, QOpenFileDialog...

All are converted from the C ++ version on the official website to the PyQt5 version.

Some details are ignored, because I don't know how to convert them. It was a good time to complete the evening!
