Hide a Button in Tkinter

Question

I want to hide a tkinter button but not when the user clicks it. I just want to hide it, at random times. How will I do that in Python? Below is the code I tried:

self.startGame = Button(self.canvas, text="Start", background='white', command = self.startGame, font=("Helvetica"))
self.startGame.place(x=770, y=400)

Hiding it:

 self.startGame.bind('<Button-1>', self.hide_me)

 def hide_me(self, event):
    print('hide me')
    event.widget.pack_forget()

It doesn't even get inside the hide_me function.

Solution

As pointed out in the comments you should use place_forget() for widgets that were set on the screen using place().

Same goes for pack() and grid(). You would use pack_forget() and grid_forget() respectively.

Here is a modified example of your code.

import tkinter as tk

class Example(tk.Tk):
    def __init__(self):
        super().__init__()
        canvas = tk.Canvas(self)
        canvas.pack()
        self.startGame = tk.Button(canvas, text="Start", background='white', font=("Helvetica"))
        self.startGame.place(x=150, y=100)
        self.startGame.bind('<Button-1>', self.hide_me)

    def hide_me(self, event):
        print('hide me')
        event.widget.place_forget()

if __name__ == "__main__":
    Example().mainloop()

That said you do not need a bind here. Simply use a lambda statement in your command like this:

import tkinter as tk

class Example(tk.Tk):
    def __init__(self):
        super().__init__()
        canvas = tk.Canvas(self)
        canvas.pack()
        self.startGame = tk.Button(canvas, text="Start", background='white', font=("Helvetica"),
                                   command=lambda: self.hide_me(self.startGame))
        self.startGame.place(x=150, y=100)

    def hide_me(self, event):
        print('hide me')
        event.place_forget()

if __name__ == "__main__":
    Example().mainloop()
