Python Tkinter - 在窗口中均匀调整窗口小部件的大小

Question

I have a small test Python app as I am learning both Python and Tkinter and I am trying to figure out how to evenly resize a grid of labels in a window. I would like to make a large grid of different colored squares so I'm using labels with a background color set to make the squares. I would like to resize the squares automatically when the user expands the window out and then have them resize and scale down to all be the same size as the window is decreased in size.

Something like this:

That resizes and scales evenly like this:

In other words: each label should all scale uniformly as the window scales. I'm not even sure if I'm using the correct terms with "window" and "widget". But I'm placing labels on a gui.

Test code I'm using to try to get this to work:

    import Tkinter

class simpleapp_tk(Tkinter.Tk):
    def __init__(self,parent):
        Tkinter.Tk.__init__(self,parent)
        self.parent = parent
        self.initialize()

    def initialize(self):
        self.grid()

        label = Tkinter.Label(self,anchor="center",bg="green")
        label.grid(column=0,row=0,sticky='EW')

        label2 = Tkinter.Label(self,anchor="center",bg="black")
        label2.grid(column=1,row=0,sticky='EW')

        label3 = Tkinter.Label(self,anchor="center",bg="red")
        label3.grid(column=2,row=0,sticky='EW')

        label4 = Tkinter.Label(self,anchor="center",bg="purple")
        label4.grid(column=0,row=1,sticky='EW')

        label5 = Tkinter.Label(self,anchor="center",bg="blue")
        label5.grid(column=1,row=1,sticky='EW')

        label6 = Tkinter.Label(self,anchor="center",bg="yellow")
        label6.grid(column=2,row=1,sticky='EW')


        self.grid_columnconfigure(0,weight=0)

if __name__ == "__main__":
    app = simpleapp_tk(None)
    app.title("Test App")
    app.mainloop()

Answer 1

Give all rows and columns the same non-zero weight.

For example:

self.grid_columnconfigure(0,weight=1)
self.grid_columnconfigure(1,weight=1)
self.grid_columnconfigure(2,weight=1)
self.grid_rowconfigure(0,weight=1)
self.grid_rowconfigure(1,weight=1)

Answer 2

Completing the answer provided by Bryan Oakley , the code for solving it in python 3 is the following.

Note that one option to manage the proportion for which the window resizes is setting the weight parameters for functions grid_columnconfigure(1,weight=1) and grid_rowconfigure(1,weight=1) to different values.

import tkinter

class simpleapp_tk(tkinter.Tk):
    def __init__(self,parent):
        tkinter.Tk.__init__(self,parent)
        self.parent = parent
        self.initialize()

    def initialize(self):
        self.grid()

        label = tkinter.Label(self,anchor="center",bg="green")
        label.grid(column=0,row=0,sticky='NSEW')

        label2 = tkinter.Label(self,anchor="center",bg="black")
        label2.grid(column=1,row=0,sticky='NSEW')

        label3 = tkinter.Label(self,anchor="center",bg="red")
        label3.grid(column=2,row=0,sticky='NSEW')

        label4 = tkinter.Label(self,anchor="center",bg="purple")
        label4.grid(column=0,row=1,sticky='NSEW')

        label5 = tkinter.Label(self,anchor="center",bg="blue")
        label5.grid(column=1,row=1,sticky='NSEW')

        label6 = tkinter.Label(self,anchor="center",bg="yellow")
        label6.grid(column=2,row=1,sticky='NSEW')


        self.grid_columnconfigure(0,weight=1)
        self.grid_columnconfigure(1,weight=1)
        self.grid_columnconfigure(2,weight=1)
        self.grid_rowconfigure(0,weight=1)
        self.grid_rowconfigure(1,weight=1)


if __name__ == "__main__":
    app = simpleapp_tk(None)
    app.title("Test App")
    app.mainloop()
