Tkinter 全局绑定

2022-01-18 00:00:00 python tkinter widget binding global

问题描述

是否可以通过一行将所有小部件绑定到一个命令?如果我可以输入一行而不是单独执行每个小部件，那就太好了.

Is it possible to bind all widgets to one command, with a single line? It would be nice if I could type in one line as opposed to doing each widget individually.

解决方案

你会使用 bind_all 方法.然后这将应用于所有小部件(除非您从某些小部件中删除绑定标签all").请注意，这些绑定最后触发，因此您仍然可以根据需要覆盖特定小部件上的应用程序范围的绑定.

You would use the bind_all method on the root window. This will then apply to all widgets (unless you remove the bindtag "all" from some widgets). Note that these bindings fire last, so you can still override the application-wide binding on specific widgets if you wish.

这是一个人为的例子:

import Tkinter as tk

class App:
    def __init__(self):
        root = tk.Tk()
        root.bind_all("<1>", self.woot)
        label1 = tk.Label(text="Label 1", name="label1")
        label2 = tk.Label(text="Label 2", name="label2")
        entry1 = tk.Entry(name="entry1")
        entry2 = tk.Entry(name="entry2")
        label1.pack()
        label2.pack()
        entry1.pack()
        entry2.pack()
        root.mainloop()

    def woot(self, event):
        print "woot!", event.widget

app=App()
