Question

I have been working on a Gui-based program using Tkinter. It needs data to display and there are a lot of different data. I tried to do it, but it did not show the right result. I mean, it cannot display other datasets and it just displays the first dataset.

Simply, its procedure is as following:

1. Load 1st data
2. Display on canvas
3. Load another data
4. Display on canvas, but it shows the first data.

Please give me some hints, comments, and help.

Thank you, guys.

In the interest of saving time and just giving an idea, I have just pulled this out from some code hoping it might help you …

class SubWindow:

    def change(self):
        self.s1Var.set("new1")

    def createWidgets(self, root):
        self.s1Var = StringVar(); self.s1Var.set("string1")

        self.s1Label = Label(root,textvariable=self.s1Var)
        self.s1Label.grid(row=0, column=5)

        self.changeButton = Button(root, text="Change", command=self.change)
        self.changeButton.grid(row=9, column=7)
