Question

如何在课程MainPage中使用课程AddPart中的某个功能？我在类Mainpage中有一些函数，我想在另一个类MainPage中使用类AddPart中的所有函数。

class MainPage(tk.Frame):
    def __init__(self, parent, controller):
        tk.Frame.__init__(self, parent) #initialise parent class --> TSS()


    def main_heading(self, heading):
        main_label = tk.Label(self, text = heading, font = LARGE_FONT, fg = 'white', bg = 'RoyalBlue1', width = 1000, height = 4)
        main_label.pack(side = 'top')

    def sub_heading(self, title):
        sub_label = tk.Label(self, text = title, font = MED_FONT, fg = 'RoyalBlue2')
        sub_label.pack(side = 'top', padx = 20, pady = 20)

    def paragraph(self, para):
        paragraph_label = tk.Label(self, text = para, font = SMALL_FONT, fg = 'gray26')
        paragraph_label.pack(side = 'top', padx = 20, pady = 20)

    def top_tool(self):
        toolbar = tk.Frame(self, bg = 'RoyalBlue2')
        AddBtn = tk.Button(toolbar, text = 'ADD', width = 10, bg = 'RoyalBlue2', fg = 'white', borderwidth=0)
        AddBtn.pack(side = 'left', padx = 0, pady = 0)
        RemBtn = tk.Button(toolbar, text = 'REMOVE', width = 10, bg = 'RoyalBlue2', fg = 'white', borderwidth=0)
        RemBtn.pack(side = 'left', padx = 0, pady = 0)
        RevBtn = tk.Button(toolbar, text = 'REVIEW', width = 10, bg = 'RoyalBlue2', fg = 'white', borderwidth=0)
        RevBtn.pack(side = 'left', padx = 0, pady = 0)
        AssignBtn = tk.Button(toolbar, text = 'ASSIGN EVENTS', width = 15, bg = 'RoyalBlue2', fg = 'white', borderwidth=0)
        AssignBtn.pack(side = 'left', padx = 0, pady = 0)
        toolbar.pack(side = 'top', fill = 'x')

#-----Second Class------
class AddPart(tk.Frame):

    def __init__(self, parent, controller):
        tk.Frame.__init__(self, parent)
        self.top_tool()
        self.main_heading("Home")

    def main_heading(self, heading):
        main_label = tk.Label(self, text = heading, font = LARGE_FONT, fg = 'white', bg = 'RoyalBlue1', width = 1000, height = 4)
        main_label.pack(side = 'top')

Answer 1

您是否尝试继承基类？ class AddPart(MainPage):

而不是class AddPart(tk.Frame, MainPage):，因为MainPage已经是tk.Frame。

Answer 2

Inheritance

我想在另一个中使用MainPage类中的所有函数 class AddPart

这就是继承的用途。正如@progmatico和@mondlos指出的那样，通过继承MainPage中的AddPart，您将可以访问所有基类函数。

看起来你的两个类都有依赖于类的函数（除非我误解了你正在使用的tk模块），所以使用类似静态方法的东西不会很好。

在您的评论中，您在尝试@mondlos建议时收到TypeError: Cannot create a consistent method resolution order (MRO) for bases错误。这是因为您从[{1}}继承了tk.Frame中包含的MainPage类型AddPart。做@progmatico建议应该工作。有几个答案表明双重继承导致了这个问题：TypeError: Cannot create a consistent method resolution order (MRO)
