Python Tkinter 命令单击

Question

我需要将命令按钮单击绑定(bind)到 python 中的函数。我已经将 flag 功能绑定(bind)到右键单击，但这仅在用鼠标右键单击时有效。当我在笔记本电脑上编写大部分代码时，这非常不方便。这是我目前拥有的:

    # set up the mouse click listeners
    self.bind('<Button-1>',self.expose)
    self.bind('<Button-2>',self.flag)
    #this is where I want to bind self.flag to command click   

如果可能，我想使用 self.bind，只需将命令单击绑定(bind)到 self.flag。是否有可能做到这一点？

你可以只使用:

self.bind("<Command-Button-1>",self.flag)

这可以在 <Button-2> 之外完成你可能还想绑定(bind) <Control-Button-1>为了兼容性。

我通常会链接到 http://infohost.nmt.edu/tcc/help/pubs/tkinter/event-modifiers.html不过目前好像down了，基本上有几个修饰符可以和Button结合使用或 Key :

Alt      True when the user is holding the alt key down.
Any      This modifier generalizes an event type. For example, the event pattern '<Any-KeyPress>' applies to the pressing of any key.
Control  True when the user is holding the control key down.
Double   Specifies two events happening close together in time. For example, <Double-Button-1> describes two presses of button 1 in rapid succession.
Lock     True when the user has pressed shift lock.
Shift    True when the user is holding down the shift key.
Triple   Like Double, but specifies three events in rapid succession.

例如，您可以绑定(bind) <Control-Shift-Double-Button-1>如果您的程序需要如此复杂。
