有多个命令时，按钮在Tkinter的pssed与Python 2.7 $ P $ [英] Have multiple commands when button is pressed in Tkinter with python 2.7

问题描述

我想要运行多个功能，当我点击一个按钮。例如，我希望我的按钮，看起来像

I want to run multiple functions when I click a button. For example I want my button to look like

self.testButton = Button(self, text = "test", 
                         command = func1(), command = func2())

当我执行该语句，我得到一个错误，因为我不能分配东西的参数两次。我怎样才能使命令执行多种功能。

when I execute this statement I get an error because I cannot allocate something to an argument twice. How can I make command execute multiple functions.

推荐答案

您可以创建功能相结合的一个泛型函数，它可能是这个样子：

You could create a generic function for combining functions, it might look something like this:

def combine_funcs(*funcs):
    def combined_func(*args, **kwargs):
        for f in funcs:
            f(*args, **kwargs)
    return combined_func

然后，你可以这样创建按钮：

Then you could create your button like this:

self.testButton = Button(self, text = "test", 
                         command = combine_funcs(func1, func2))
