Button Command - Heyjoe - Jul-19-2020 Hello Python Users I have a button(mybutton) in a file called startpage. If I click on this button I want it to run a function in a file called om. The function is called openingmenu. mybutton = Button(root, text="Click me for opening menu", bg="white", fg="firebrick", \ relief = "groove", font = "Helvitica 60", command = from om import openingmenu) Mybutton.pack()So I tried to set command as command = from om import openingmenu, but I get an invalid syntax error. Can this be done? RE: Button Command - deanhystad - Jul-19-2020 import om mybutton = Button(root, text="Click me for opening menu", bg="white", fg="firebrick", \ relief = "groove", font = "Helvitica 60", command = om.openingmenu) Mybutton.pack() RE: Button Command - Heyjoe - Jul-19-2020 This is the entire code except for the function, using the changes you suggested. from tkinter import * root = Tk() root.geometry("700x700") import om mybutton = Button(root, text="Click me for opening menu.", bg="white", fg="firebrick", \ relief = "groove", font = "Helvitica 60",command = om.openingmenu) mybutton.pack()The code does not create the mybutton. The code runs the function. This produces a menu. I don't understand why the code runs the function because this is not supposed to happen until after mybutton is clicked. RE: Button Command - menator01 - Jul-19-2020 use a callback import om from functools import partial def callback(): om.openingmenu() tk.Button(...., command=partial(callback)) RE: Button Command - Heyjoe - Jul-20-2020 Thanks all. I was able to get Deanhystad's solution to work. |
