如何在 Tkinter 中正确构建框架

Question

I'm creating a simple chat app and I'm having a problem with packing Frames into the main window. Here is the part of my code:

class MainApplication(Frame):
    def __init__(self, parent, *args, **kwargs):
        Frame.__init__(self, parent, *args, **kwargs)

        self.server_frame = ServerFrame(self)
        self.server_frame.pack(side="left")
    
        self.client_frame = ClientFrame(self)
        self.client_frame.pack(side="left")

        self.chat_frame = ChatFrame(self)
        self.chat_frame.pack(side="right")

        self.additional_frame = AdditionalFrame(self)
        self.additional_frame.pack(side="bottom", fill="x")

How can I get it to GUI looks like this:

pack() is best when all of the widgets need to be in a single row or column. For this I'd recommend grid() :

class MainApplication(Frame):
    def __init__(self, parent, *args, **kwargs):
        Frame.__init__(self, parent, *args, **kwargs)

        self.server_frame = ServerFrame(self)
        self.server_frame.grid(row=0, column=0)
    
        self.client_frame = ClientFrame(self)
        self.client_frame.grid(row=1, column=0)

        self.chat_frame = ChatFrame(self)
        self.chat_frame.grid(row=0, column=1, rowspan=2)

        self.additional_frame = AdditionalFrame(self)
        self.additional_frame.grid(row=2, column=0, columnspan=2, sticky='ew')
