本文适用场景:想用Tkinter开发界面程序并屏幕居中,但没找到相应的API。
这两天玩了玩Tkinter,感觉不错,就是屏幕居中这个问题在网上搜了很长时间也没
找到答案,最后没办法,看它的文档,用自己的方法实现了。
方法很土,就是获取初始化的窗体大小和屏幕大小,再通过计算得到大体值。
以下是代码:
#! /usr/bin/python
'''
File : screenCenter.pyw
Author : Mike
E-Mail : Mike_Zhang@live.com
'''
from Tkinter import *
rt = Tk()
rt.resizable(False,False)
rt.title("Screen center")
rt.update() # update window ,must do
curWidth = rt.winfo_reqwidth() # get current width
curHeight = rt.winfo_height() # get current height
scnWidth,scnHeight = rt.maxsize() # get screen width and height
# now generate configuration information
tmpcnf = '%dx%d+%d+%d'%(curWidth,curHeight,
(scnWidth-curWidth)/2,(scnHeight-curHeight)/2)
rt.geometry(tmpcnf)
rt.mainloop()
好,就这些了,希望对你有帮助。

Python and C each have their own advantages, and the choice should be based on project requirements. 1) Python is suitable for rapid development and data processing due to its concise syntax and dynamic typing. 2)C is suitable for high performance and system programming due to its static typing and manual memory management.

Choosing Python or C depends on project requirements: 1) If you need rapid development, data processing and prototype design, choose Python; 2) If you need high performance, low latency and close hardware control, choose C.

By investing 2 hours of Python learning every day, you can effectively improve your programming skills. 1. Learn new knowledge: read documents or watch tutorials. 2. Practice: Write code and complete exercises. 3. Review: Consolidate the content you have learned. 4. Project practice: Apply what you have learned in actual projects. Such a structured learning plan can help you systematically master Python and achieve career goals.

Methods to learn Python efficiently within two hours include: 1. Review the basic knowledge and ensure that you are familiar with Python installation and basic syntax; 2. Understand the core concepts of Python, such as variables, lists, functions, etc.; 3. Master basic and advanced usage by using examples; 4. Learn common errors and debugging techniques; 5. Apply performance optimization and best practices, such as using list comprehensions and following the PEP8 style guide.

Python is suitable for beginners and data science, and C is suitable for system programming and game development. 1. Python is simple and easy to use, suitable for data science and web development. 2.C provides high performance and control, suitable for game development and system programming. The choice should be based on project needs and personal interests.

Python is more suitable for data science and rapid development, while C is more suitable for high performance and system programming. 1. Python syntax is concise and easy to learn, suitable for data processing and scientific computing. 2.C has complex syntax but excellent performance and is often used in game development and system programming.

It is feasible to invest two hours a day to learn Python. 1. Learn new knowledge: Learn new concepts in one hour, such as lists and dictionaries. 2. Practice and exercises: Use one hour to perform programming exercises, such as writing small programs. Through reasonable planning and perseverance, you can master the core concepts of Python in a short time.

Python is easier to learn and use, while C is more powerful but complex. 1. Python syntax is concise and suitable for beginners. Dynamic typing and automatic memory management make it easy to use, but may cause runtime errors. 2.C provides low-level control and advanced features, suitable for high-performance applications, but has a high learning threshold and requires manual memory and type safety management.
