Note: For a list of commonly used events, see the Event types section of the Tkinter 8.5 reference. 运用命令 Using command Every Button widget has a command attribute that you can assign to a function. Whenever the button is pressed, the function is executed. 本质就是把事件处理函数当做comman...

Tkinter具有很多优点:它是跨平台的,因此相同的代码可在窗口,macOS和Linux上运行。视觉元素是使用本机操作系统元素呈现的,因此使用Tkinter构建的应用程序看起来像属于平台自身的。 Tkinter也有缺点:使用Tkinter构建的GUI看起来已经过时了。如果你想要一个fashion、现代化的界面,那么Tkinter可能暂时不能满足你的需求。
defcreate_list(*elements): """ 创建一个列表,其中元素由elements参数指定。 elements参数应该是可变数量的位置参数。 """ returnlist(elements) 使用示例: my_list = create_list(1,2,3) print(my_list)# [1, 2, 3] 类工厂函数 type() classtype(object) ...
问访问绑定到事件的函数的返回值(tkinter)EN顺便说一句,随着时间的推移,您正在编写的代码将很难维护。
It maintains a list of events that have occurred. It runs an event handler any time a new event is added to that list. Update your event loop to use window.mainloop() instead of your own event loop: Python import tkinter as tk # Create a window object window = tk.Tk() # Create ...
想实现这个功能可以在槽函数中调用 sender() 方法获取发送信号的对象类型。然后进行处理,具体代码如下:...
