按下按钮时有多个命令 [英] Have multiple commands when button is pressed

问题描述

我想在单击按钮时运行多种功能。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())

当我执行此语句时，我得到一个错误，因为我无法两次为参数分配内容。如何使命令执行多个功能。

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

您可以创建用于组合功能的通用功能，看起来可能像这样：

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

然后您可以像这样创建按钮：

Then you could create your button like this:

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