3、创建一个画图用的画布 from tkinter import* tk = Tk() canvas = Canvas(tk,width = 500,height = 500) canvas.pack() 1. 2. 3. 4. 4、在Python中,X坐标从左往右为正,Y坐标从上往下为正 5、在Python中,画矩形给出左上角和右下角坐标即可。 from tkinter import* tk = Tk() canvas = Canv...
23、为Canvas中的图形对象设置点击特效 import tkinter as tk def toggle_color(event): canvas.itemconfig(event.widget, fill="green" if event.widget in selected else "blue") if event.widget in selected: selected.remove(event.widget) else: selected.append(event.widget) root = tk.Tk() canvas = ...
Select a floor to go to in the building. Click the 'X' button at the top-corner of this window and you will close it. It's the same for buttons in Tkinter. Push the button and maybe display some text, or maybe call another function and perform some action. We can use the Button...

Tkinter支持16个核心的窗口部件,这个16个核心窗口部件类简要描述如下: Button:一个简单的按钮,用来执行一个命令或别的操作。 Canvas:组织图形。这个部件可以用来绘制图表和图,创建图形编辑器,实现定制窗口部件。 Checkbutton:代表一个变量,它有两个不同的值。点击这个按钮将会在这两个值间切换。

正常在Button中设置触发函数是不可以加()的,如果加上(),就会出现不等点击按钮就调用了函数的情况出现,所以一般情况下程序如下: def signIn(self): pass Button(self, text='注册', command=self.signIn).grid(row=6, column=0, stick=E) 那么如果我们想传递参数的话应该如何做呢?答案是可以使用lambda进行传...
