I installed the omnet++3.3 version, first you can go to OMNETPP's official website http://www.omnetpp.org/Download the latest version. Take 3.3 As an example: the download is omnetpp-3.3-src.tgz 1) Decompression: Tar zxvf omnetpp-3.3-src.tgz 2 because of the installation of the rear, omnet++ will be prompted for Tcl and TK two installation files, so here first installed, later on the easy, Tcl and TK can go

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 not good, the execution speed is slow.The general method of using Tkinter is:From Tkinter Import *Or: Import Tkinter the difference bet

very effectively, mainly because of its large function library. Therefore, users do not need to enter the system environment or operating system, nor reference modules. Using Python programming, small programs are still small programs, and there is no need to spend too much time and cost. In addition to its Core platform, Python can run on MS-DOS, Amiga, BeOS, OS/2, VMS, QNX, and many other operating systems. You can even run Python programs on your handheld computer.

Abstract: In this chapter, we will learn the graphical interface programming of python. In python, the default graphical interface is Tkinter (interface). Note that k is in lower case. 1. Programming Environment and running principle if you are using a version earlier than python3.0, the GUI is not installed by default. You need to use yum or apt to install tkinter. It is the default GUI library of python. Based on the Tk toolset, it was originally de

Scale is the number range for the output limit, and you can specify a maximum value, a minimum value, and a stride value. The scale component defaults to vertical, a maximum value of 100, a minimum value of 0, and a step distance of 11. Create a scaleFrom tkinter Import *root = Tk () scale (root). Pack () Root.mainloop ()2. Change the default valueFrom tkinter Import *root = Tk () scale (root, from_ =

Hello, Tkinter. But enough talk. Some code instead. As you know, the every serious tutorial should start with a "Hello World"-type example. In this overview, we'll show you the only one such example, but two. Every serious tutorial starts with a "Hello World" example, and in order to keep this routine we will show you two examples.
