SO i have been working on this for a while now and i just have no idea what i am doing wrong. I have a main window my 'root' but i also have a 'helpmenu'. right now, when you close the root helpmenu will remain opened if you opened it. i want helpmenu to close when the root closes.
i have tried to cutout all the lines of code from my program which i believed had no baring on the situation but forgive me if it is still long.
import atexit
from tkinter import *
root = Tk()
def quit():
helpmenu.destroy()
atexit.register(quit)
def helpmenu():
helpmenu = Tk()
helpmenu.geometry('800x600')
helpmenu.title('Help')
help_Label = Label(helpmenu, text='Welcome to the Boring Program!')
help_Label.pack()
class GUI(object):
def __init__(self, master):
self.master = master
def activateCheck1():
if c1Var.get() == 1: #whenever checked
c3.config(state=NORMAL)
elif c1Var.get() == 0: #whenever unchecked
c3.config(state=DISABLED)
def activateCheck2():
if c2Var.get() == 1: #whenever checked
c4.config(state=NORMAL)
elif c2Var.get() == 0: #whenever unchecked
c4.config(state=DISABLED)
c1Var = IntVar()
c2Var = IntVar()
c1_Label = Label(root, text="Select Which Edges to Program")
c1_Label.grid(row=2, columnspan=2)
c1 = Checkbutton(root, text="Left Edge", variable=c1Var, command=activateCheck1)
if parser.get('CONFIGURATION', 'LeftEdgeProgram') == '1':
c1.select()
c1.grid(row=3, column=0)
c2 = Checkbutton(root, text="Right Edge", variable=c2Var, command=activateCheck2)
if parser.get('CONFIGURATION', 'RightEdgeProgram') == '1':
c2.select()
c2.grid(row=3, column=1)
c3Var = IntVar()
c4Var = IntVar()
c3_Label = Label(root, text="Select Which Edges to Insert Glue and Dowels")
c3_Label.grid(row=4, columnspan=2)
c3 = Checkbutton(root, text="Left Edge", variable=c3Var)
if parser.get('CONFIGURATION', 'LeftEdgeDowel') == '1':
c3.select()
c3.grid(row=5, column=0)
c4 = Checkbutton(root, text="Right Edge", variable=c4Var)
if parser.get('CONFIGURATION', 'RightEdgeDowel') == '1':
c4.select()
c4.grid(row=5, column=1)
menubar = Menu(root)
filemenu = Menu(menubar, tearoff=0)
filemenu.add_command(label="Print", state='disabled')
filemenu.add_command(label="Save Configuration", command=save_config)
filemenu.add_command(label="Help", command=helpmenu)
filemenu.add_command(label="Restore Defaults", state='disabled')
filemenu.add_command(label="About", command=restore_config)
menubar.add_cascade(label="Options", menu=filemenu)
root.config(menu=menubar)
myGUI = GUI(root)
root.mainloop()
Firstly you are creating two instances of a tk()
windows. Creating two tk()
windows almost never should be done, this is because two tk
windows cannot communicate with eachother. Instead you should use a TopLevel
window.
You should also change your HelpMenu
to a class object which inherits the TopLevel
Class
This should look something like this:
class HelpMenu(Toplevel):
def __init__(self, master, *args, **kwargs):
super(HelpMenu, self).__init__(master, *args, **kwargs)
self.geometry('800x600')
self.title('Help')
help_Label = Label(self, text='Welcome to the Boring Program!')
help_Label.pack()
The only thing that now needs to be changed is the command for the help option in the toolbar
Something like this (notice I am using a lambda function to make this change):
filemenu.add_command(label="Help", command= lambda:HelpMenu(self.master) )
This will fix your problem, because when the master window of a TopLevel
window is closed the TopLevel
window is automatically closed.
