Tkinter is the standard GUI library in the python release version. That is to say, tkinter can be used after python is installed by default. I have referenced a tutorial and wrote someCodeTry: # File: test. pyfrom tkinter import * class app: def _ init _ (self, Master): Self. frame = frame (master) self. frame. pack () self. button = button (self. frame, text

If you want to use Python to develop a graphical interface, there are many tools to choose from, each with the pros and cons, previously used Wxpython+boa-constructor, has not been clear. New understanding of the next PyQt4, seems to use this person also more, so decided to start learning this. Version:pyqt-py2.7-x86-gpl-4.9.1-1.exe PyQt4 takes a QT designer and uses it to create an interface, layout controls such as Form,button,text, and so on, using

The style specifies whether the load is loaded horizontally or vertically, and is loaded vertically ga_verticalUnlike some other components, it is not enough to construct the progress bar in the window alone, so the progress bar is static.
