Tkinter的全局绑定

问题描述

是否有可能所有控件绑定到一个命令，一个单行？这将是很好，如果我能在同一行，而不是单独做每个插件类型。

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.

推荐答案

您将使用方法。那么这将适用于所有小（除非你删除一些小部件bindtag全）。请注意，这些绑定去年火，所以你仍然可以覆盖应用程序范围内，如果你想在特定的部件结合。

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.

下面是一个人为的例子：

Here's a contrived example:

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()
