i'm trying create login tkinter entry. compare input password , if correct supposed access more stuff in menu bar.
if understand correctly need update window in order menu update, cant figure out how. , variable "moberg" don't seems update true. might 1 global(?) , other 1 belongs class. cant figure out how make work either.
here sample of i've done far.
from tkinter import * moberg="no" class pcmsyntax(frame): def update(): print("updated") #only visual, remove later app.mainloop.after(1, update) def __init__(self, master): super().__init__(master) self.pack(fill=both, expand=true) self.initui() def initui(self): menubar = menu(self.master) self.master.config(menu=menubar) syntaxmenu = menu(menubar, tearoff=false) submenu = menu(syntaxmenu) syntaxmenu.add_cascade(label='arithmetic exp', underline=0, command='') syntaxmenu.add_cascade(label='assign & compare', underline=0, command='') syntaxmenu.add_separator() syntaxmenu.add_cascade(label='math', menu=submenu, underline=0) submenu.add_command(label="abs()", command='') if moberg == true: syntaxmenu.add_cascade(label='no public access', menu=submenu, underline=0) submenu.add_command(label="onlyforlabtech()") menubar.add_cascade(label="syntax", underline=0, menu=syntaxmenu) menubar.add_cascade(label="login", underline=0, command=self.onlogin) def onlogin(self): self.newwindow = toplevel(self.master) self.app = password(self.newwindow) class password(): def __init__(self, master): self.master = master self.frame = frame(self.master) self.pwd = entry(self.master, width=30, bg="whitesmoke", foreground="whitesmoke") self.pwd.pack() self.verifybutton = button(self.frame, text = 'verify', width = 25, command = self.verify_password) self.verifybutton.pack() self.frame.pack() def verify_password(self): user_entry = self.pwd.get() if str(user_entry) == "test": moberg=true print(moberg) #only visual, remove later pcmsyntax.update self.master.destroy() else: moberg=false print(moberg) #only visual, remove later self.master.destroy() def main(): root = tk() root.geometry("560x600") app = pcmsyntax(master=root) app.mainloop() if __name__ == '__main__': main()
you achieve you're looking below:
from tkinter import * class app: def __init__(self, root): self.root = root self.public = frame(self.root, borderwidth=1, relief="solid") #public, visible frame self.hidden = frame(self.root, borderwidth=1, relief="solid") #hidden, private frame self.label1 = label(self.public, text="this text , on here public.") #this inside public frame , visible self.entry1 = entry(self.public) #so self.label2 = label(self.hidden, text="this text , on here hidden , appears after login.") #this 1 in hidden frame , private before login self.button1 = button(self.public, text="login", command=self.command) #this in public frame self.public.pack(side="left", expand=true, fill="both") #we pack public frame on left of window self.label1.pack() #then pack widgets both frames here , below self.entry1.pack() self.label2.pack() self.button1.pack() def command(self): #whenever login button pressed called if self.button1.cget("text") == "login" , self.entry1.get() == "password": #we check if button in login state or not , if password correct self.hidden.pack(side="right", expand=true, fill="both") #if pack hidden frame makes , it's contents visible self.button1.configure({"text": "logout"}) #we set button logout state elif self.button1.cget("text") == "logout": #if button in logout state self.hidden.pack_forget() #we pack_forget frame, removes , it's contents view self.button1.configure({"text": "login"}) #and set button login state root = tk() app(root) root.mainloop() this self explanatory , isn't i've explained what's happening.
this 1 way of many of achieving you're looking for.
i'd point out login systems complicated , if you're looking use serious or package sell way have done not secure.
i'd recommend looking @ other ways people handle sensitive information in tkinter.
