im trying to use the container column and row configure methods in order to create 128 'boxes' that i am able to grid widgets in for each of my pages. However, it doesn't work when i run the program, when i try passing 'parent' instead of 'self' when i create my widgets in my different pages, my show_frame function doesnt work and instead it displays the widgets from both of my pages at the same time.

CodePudding user response：

You're calling rowconfigure and columnconfigure on the container, but the container only has a single row and a single column that is used to hold each "page". You need to be calling those methods on each page rather than on the container.

class homePage():
    def __init__(self, parent, controller, *args, **kwargs):
        ...

        for i in range(128):
            self.columnconfigure(i,weight=1)

        for i in range(128):
            self.rowconfigure(i,weight=1)
