一、创建一个可以点的按钮 用tkinter创建一个带按钮的简单程序，代码如下： >>> from tkinter import*...
self.canvas = Canvas(self, width=300, height=200, bg="green") self.canvas.pack()# 画一条直线line = self.canvas.create_line(10,10,30,20,40,50)# 画一个矩形,rect = self.canvas.create_rectangle(50,50,100,100)# 画一个椭圆,坐标两双。为椭圆的边界矩形左上角和底部右下角oval = self.c...

为了让 Canvas 使用鼠标画出基本图形元素(线段、椭圆、矩形、弧形),本文介绍一种统一的接口。 from tkinter import Canvas class Meta(Canvas): '''Graphic elements are composed of line(segment), rectangle, ellipse, and arc. ''' def __init__(self, master=None, cnf={}, **kw): '''The base ...
