当我按下其中一个按钮 <4 时，我试图获取一个要调用的 setcolor 定义。我在编写设置颜色定义时遇到问题。一旦我按下按钮更改从输入框收集的文本框中的文本颜色，最好的方法是什么？当我单击“红色”框时，文本变为红色，“蓝色”变为蓝色等。

我需要再次调用 dofileopen 还是可以在事后更改颜色？

我不确定我理解正确，但是您问如何编写setcolor函数以使其具有颜色，然后设置相应文本框的颜色？您可以执行以下操作：

def setcolor(self,bname):
    if bname == "RED": #or 1, can't tell how you've written it
        self.text_in.config(foreground = RED) #I think that's how colors work in tkinter
    elif bname == "BLUE":
        self.text_in.config(foreground = BLUE)
    #etc etc

self它假设Entry您想要更改。

所有 Tkinter 小部件都有一个configure方法，可让您更改与该小部件关联的任何选项。例如，要更改小部件的前景色，您可以这样做：

self.output.configure(foreground="red")

对于文本小部件，您可以通过配置标签来更改一系列字符的属性，然后将该标签添加到一系列文本中。例如：

self.output.tag_configure("tag1", foreground="red")
...
self.output.tag_add("tag1", 1.0, 2.0)
