what is python tkinter

python tkinter is the standard GUI library of Python. Python can use Tkinter to quickly create GUI applications. Since Tkinter is built into the python installation package, you can import the Tkinter library as long as Python is installed.

Detailed explanation of python tkinter:

Python provides multiple graphical development interface libraries, several commonly used Python GUIs The library is as follows:

• Tkinter: The Tkinter module (Tk interface) is the interface of Python's standard Tk GUI toolkit. Tk and Tkinter can be used on most Unix platforms and can also be applied In Windows and Macintosh systems. Subsequent versions of Tk8.0 can implement local window styles and run well on most platforms.

• wxPython: wxPython is an open source software and an excellent GUI graphics library for the Python language, allowing Python programmers to easily create complete and fully functional GUI user interfaces .

• Jython: Jython programs can be seamlessly integrated with Java. In addition to some standard modules, Jython uses Java modules. Jython has almost all the modules in standard Python that do not depend on the C language. For example, Jython's user interface will use Swing, AWT or SWT. Jython can be dynamically or statically compiled into Java bytecode.

Tkinter Programming

Tkinter is the standard GUI library for Python. Python uses Tkinter to quickly create GUI applications.

Since Tkinter is built into the python installation package, you can import the Tkinter library after installing Python, and IDLE is also written in Tkinter. Tkinter can still handle the simple graphical interface easily.

Note: The library name used by Python3.x version is tkinter, that is, the first letter T is lowercase.

import tkinter

Create a GUI program

1. Import the Tkinter module

2. Create a control

3. Specify the master of this control, that is, which one this control belongs to.

4. Tell GM (geometry manager) that a control has been generated.

Example (Python3.x)

#!/usr/bin/python3
 
import tkinter
top = tkinter.Tk()
# 进入消息循环
top.mainloop()

Example (Python2.x)

#!/usr/bin/python
# -*- coding: UTF-8 -*-
 
import Tkinter
top = Tkinter.Tk()
# 进入消息循环
top.mainloop()

The execution result of the above code is as follows:

tkwindow

Example

#!/usr/bin/python
# -*- coding: UTF-8 -*-
 
# Python2.x 导入方法
from Tkinter import *           # 导入 Tkinter 库
# Python3.x 导入方法
#from tkinter import * 
root = Tk()                     # 创建窗口对象的背景色
                                # 创建两个列表
li     = ['C','python','php','html','SQL','java']
movie  = ['CSS','jQuery','Bootstrap']
listb  = Listbox(root)          #  创建两个列表组件
listb2 = Listbox(root)
for item in li:                 # 第一个小部件插入数据
    listb.insert(0,item)
 
for item in movie:              # 第二个小部件插入数据
    listb2.insert(0,item)
 
listb.pack()                    # 将小部件放置到主窗口中
listb2.pack()
root.mainloop()                 # 进入消息循环

The above code execution result is as shown below:

Tkinter component

Tkinter provides various controls, such as buttons, labels and text boxes, for use in a GUI application. These controls are often called controls or widgets.

There are currently 15 Tkinter components. We present these components along with a brief introduction in the following table:

Standard Properties

Standard Properties Also These are the common properties of all controls, such as size, font, color, etc.

Geometry Management

The Tkinter control has a specific geometry state management method to manage the entire control area organization. The following is disclosed by Tkinter Geometry management class: package, grid, position
