Refresh a tkinter frame on button press

Question

I am utilising code from Switch between two frames in tkinter to make my GUI. I have a frame with refresh and restart buttons.

My original idea was for the restart

Answer 1

The first step is to have your button call a proper function rather than using lambda. Unless you understand why and when to use lambda, it usually just makes the code harder to write and understand.

Once you have it call a function, you can use the function to clear the entries.

Example:

class PLG(tk.Frame):
    def __init__(self, parent, controller):
        ...
        tk.Button(self, text="Restart", command=self.restart)
        tk.Button(self, text="Refresh", command=self.refresh)
        ...

    def restart(self):
        self.refresh()
        self.controller.show_frame("StartPage")

    def refresh(self):
        self.weight_entry.delete(0, "end")
        self.text.delete("1.0", "end")
