rapid gui programming with python and qt

First, Tkinter Introduction Tkinter is a Python module that is an interface to call TCL/TK, a Cross-platform scripting interface. Tkinter is not the only Python graphics programming interface, but it is one of the more popular. The biggest feature is Cross-platform, the disadvantage is that performance is not good, execution speed is slow.The general way to use

Wxpython is PythonProgramming LanguageA Gui toolbox. He makes PythonProgramUsers can easily create programs with robust and powerful graphic user interfaces. It is used by the Python language to bind the popular wxWidgets cross-platform GUI tool library. WxWidgets is written in C ++. Like the Python language and the

I. Introduction of Tkinter Tkinter is a Python module, an interface called TCL/TK, which is a cross-platform scripting GUI interface. Tkinter is not the only Python graphics programming interface, but it is one of the more popular ones. The biggest feature is the cross-platform, the disadvantage is the performance is

point.So how do you make changes to the function variables? It's really simple, define a list, and then convert the list to tuples. The modified function is as follows:Def changeitems ():Tnames.append (' Java ')Cnames.set (Tuple (tnames))root = tkinter.tk ()Root.geometry (' +400+200 ')Root.minsize (400,200)Root.title ("Test")Tnames = [' Python ', ' TCL ', ' Ruby ']CNAMEs = Stringvar ()Cnames.set (Tuple (tnames))L = Listbox (root, listvariable = Cname

Transferred from: http://www.cnblogs.com/hhh5460/p/4232086.htmlPrefaceI am a rookie, this series is my study notes.PyQt5 out for some time, PyQt5 compared to PyQt4 some changes, and the Internet is almost all the PyQt4 of the tutorial, copy the words will be wrong most.ERIC6 is also just out, eric6 and PyQt5 combine the tutorials online with almost no.I am also learning, while groping, and record with this, hope to help the needs of friends, but also hope to pass the hero more advice as well.Int

SummaryIn this lesson we master the following points: About Wxpython Familiarity with the environment, especially git Can run out of Wxpython window Understand the differences between CLIENTDC and PAINTDC Draw Line If you draw a polygon through specific points, it is inconvenient, and if you calculate the area of the polygon, compare the size

Absrtact: When programming with the Python process GUI, you often need to use the ListBox component, and how to control the display of the ListBox component, you need to use the ScrollBar component. This article focuses on the binding of actions between two GUI components--------the action of one component will start t
