"GraphWin Object is not callable"

When I a section of code into a new function, it comes up with "GraphWin Object is not callable"

This is my whole code

Code:

from graphics import *
import urllib.request, re

def LoginScreen():
    LoginScreen = GraphWin("Login",300,100)
    file = open("users.csv","r")
    readfile = file.read()
    UsernameLabel = Text(Point(45,25),"Username: ")
    UsernameLabel.draw(LoginScreen)
    UsernameText = Entry(Point(158,25),16)
    UsernameText.draw(LoginScreen)
    username = ''
    LoginScreen.getMouse()
    LoginScreen.close()

def RegisterScreen():
    RegisterScreen = GraphWin("Register",300,150)
    UsernameRegLabel = Text(Point(45,25),"Username: ")
    UsernameRegLabel.draw(RegisterScreen)
    UsernameRegText = Entry(Point(175,25),20)
    UsernameRegText.draw(RegisterScreen)
    PasswordRegLabel = Text(Point(45,50),"Password: ")
    PasswordRegLabel.draw(RegisterScreen)
    PasswordRegText = Entry(Point(175,50),20)
    PasswordRegText.draw(RegisterScreen)
    PasswordConfRegLabel = Text(Point(52,75),"Confirm: ")
    PasswordConfRegLabel.draw(RegisterScreen)
    PasswordConfRegText = Entry(Point(175,75),20)
    PasswordConfRegText.draw(RegisterScreen)
    EmailRegLabel = Text(Point(60,100),"Email: ")
    EmailRegLabel.draw(RegisterScreen)
    EmailRegText = Entry(Point(175,100),20)
    EmailRegText.draw(RegisterScreen)
    SubmitButton = Rectangle(Point(195,115),Point(265,140))
    SubmitButton.draw(RegisterScreen)
    SubmitButtonText = Text(Point(230,128),"Submit")
    SubmitButtonText.draw(RegisterScreen)
    CloseButton = Rectangle(Point(115,115),Point(185,140))
    CloseButton.draw(RegisterScreen)
    CloseButtonText = Text(Point(150,128),"Close")
    CloseButtonText.draw(RegisterScreen)

def GetMouseRegistration():
    MouseRegScreen = RegisterScreen.getMouse()
    RegScreenX = MouseRegScreen.getX()
    RegScreenY = MouseRegScreen.getY()

    if RegScreenX>=195 and RegScreenX<=265:
        if RegScreenY>=115 and RegScreenY<=140:
            ProcessRegister()
    elif RegScreenX>=115 and RegScreenX<=185:
        if RegScreenY>=115 and RegScreenY<=140:
            RegisterScreen.close()

def ValidateRegistration():
    return

def ProcessRegister():
    ValidateRegistration()

def GetMouse():
    MouseMainScreen = MainWin.getMouse()
    MainScreenX = MouseMainScreen.getX()
    MainScreenY = MouseMainScreen.getY()
    
    if MainScreenX>=197 and MainScreenX<=260:
        if MainScreenY>=230 and MainScreenY<=250:
            LoginScreen()
    if MainScreenX>=197 and MainScreenX<=297:
        if MainScreenY>=260 and MainScreenY<=285:
            RegisterScreen()
    
def DrawBackground():
    return
    
def DrawMenuItems():
    Main = Text(Point(300,200),"Main Menu")
    Main.setSize(32)
    Main.draw(MainWin)
    Login = Text(Point(228,240),"Login")
    Login.setSize(20)
    Login.draw(MainWin)
    Register = Text(Point(245,270),"Register")
    Register.setSize(20)
    Register.draw(MainWin)

MainWin = GraphWin("Fantasy Football",600,600)

DrawBackground()
DrawMenuItems()
while True:
    GetMouse()

This is the original code that I'm changing

Code:

def RegisterScreen():
    RegisterScreen = GraphWin("Register",300,150)
    UsernameRegLabel = Text(Point(45,25),"Username: ")
    UsernameRegLabel.draw(RegisterScreen)
    UsernameRegText = Entry(Point(175,25),20)
    UsernameRegText.draw(RegisterScreen)
    PasswordRegLabel = Text(Point(45,50),"Password: ")
    PasswordRegLabel.draw(RegisterScreen)
    PasswordRegText = Entry(Point(175,50),20)
    PasswordRegText.draw(RegisterScreen)
    PasswordConfRegLabel = Text(Point(52,75),"Confirm: ")
    PasswordConfRegLabel.draw(RegisterScreen)
    PasswordConfRegText = Entry(Point(175,75),20)
    PasswordConfRegText.draw(RegisterScreen)
    EmailRegLabel = Text(Point(60,100),"Email: ")
    EmailRegLabel.draw(RegisterScreen)
    EmailRegText = Entry(Point(175,100),20)
    EmailRegText.draw(RegisterScreen)
    SubmitButton = Rectangle(Point(195,115),Point(265,140))
    SubmitButton.draw(RegisterScreen)
    SubmitButtonText = Text(Point(230,128),"Submit")
    SubmitButtonText.draw(RegisterScreen)
    CloseButton = Rectangle(Point(115,115),Point(185,140))
    CloseButton.draw(RegisterScreen)
    CloseButtonText = Text(Point(150,128),"Close")
    CloseButtonText.draw(RegisterScreen)

    MouseRegScreen = RegisterScreen.getMouse()
    RegScreenX = MouseRegScreen.getX()
    RegScreenY = MouseRegScreen.getY()

    if RegScreenX>=195 and RegScreenX<=265:
        if RegScreenY>=115 and RegScreenY<=140:
            ProcessRegister()
    elif RegScreenX>=115 and RegScreenX<=185:
        if RegScreenY>=115 and RegScreenY<=140:
            RegisterScreen.close()

The last section I want to take out and put in another function like this.

Code:

def GetMouseRegistration():
    MouseRegScreen = RegisterScreen.getMouse()
    RegScreenX = MouseRegScreen.getX()
    RegScreenY = MouseRegScreen.getY()

    if RegScreenX>=195 and RegScreenX<=265:
        if RegScreenY>=115 and RegScreenY<=140:
            ProcessRegister()
    elif RegScreenX>=115 and RegScreenX<=185:
        if RegScreenY>=115 and RegScreenY<=140:
            RegisterScreen.close()

I've tried making the RegisterScreen Window a global variable, but that's when it says it isn't callable.

I'm also having a problem when the user clicks on the x in the top right corner to close it, is there any way to stop the error from crashing the program?

You should use inheritance to create two classes(LoginScreenC, RegisterScreenC) that are derived from GraphWin, in these classes you can overwrite the GetMouse function.
Then you can create:

MainWin = LoginScreenC("Fantasy Football",600,600)

and in your RegisterScreen() function change:

RegisterScreen = RegisterScreenC("Register",300,150)

and append to the end of this function:

RegisterScreen.getMouse()
RegisterScreen.close()

Obviously you have to overwrite the getMouse functions in the two classes to fit your buttonsizes and needs

But why do you want to put this in a extra function anyway, this seems to work just fine:

Code:

def RegisterScreen():
    RegisterScreen = GraphWin("Register",300,150)
    UsernameRegLabel = Text(Point(45,25),"Username: ")
    UsernameRegLabel.draw(RegisterScreen)
    UsernameRegText = Entry(Point(175,25),20)
    UsernameRegText.draw(RegisterScreen)
    PasswordRegLabel = Text(Point(45,50),"Password: ")
    PasswordRegLabel.draw(RegisterScreen)
    PasswordRegText = Entry(Point(175,50),20)
    PasswordRegText.draw(RegisterScreen)
    PasswordConfRegLabel = Text(Point(52,75),"Confirm: ")
    PasswordConfRegLabel.draw(RegisterScreen)
    PasswordConfRegText = Entry(Point(175,75),20)
    PasswordConfRegText.draw(RegisterScreen)
    EmailRegLabel = Text(Point(60,100),"Email: ")
    EmailRegLabel.draw(RegisterScreen)
    EmailRegText = Entry(Point(175,100),20)
    EmailRegText.draw(RegisterScreen)
    SubmitButton = Rectangle(Point(195,115),Point(265,140))
    SubmitButton.draw(RegisterScreen)
    SubmitButtonText = Text(Point(230,128),"Submit")
    SubmitButtonText.draw(RegisterScreen)
    CloseButton = Rectangle(Point(115,115),Point(185,140))
    CloseButton.draw(RegisterScreen)
    CloseButtonText = Text(Point(150,128),"Close")
    CloseButtonText.draw(RegisterScreen)
    MouseRegScreen = RegisterScreen.getMouse()
    RegScreenX = MouseRegScreen.getX()
    RegScreenY = MouseRegScreen.getY()

    if RegScreenX>=195 and RegScreenX<=265:
        if RegScreenY>=115 and RegScreenY<=140:
            ProcessRegister()
    elif RegScreenX>=115 and RegScreenX<=185:
        if RegScreenY>=115 and RegScreenY<=140:
            RegisterScreen.close()
