Pravim jednostavan GUI program (nešto kao To Do List), imam problem sa addovanjem itema u listbox. U svom programu imam klasu Priority, te sam pokušao da napravim instancu te klase i da u konstruktoru prosledim atribute subject i priority, pa da ceo taj item dodam u listbox. Međutim, dobijam error:

Citat:

/usr/bin/python3.5 /home/cali/PycharmProjects/priorities/priorities.py
Exception in Tkinter callback
Traceback (most recent call last):
File "/usr/lib/python3.5/tkinter/__init__.py", line 1553, in __call__
return self.func(*args)
File "/home/cali/PycharmProjects/priorities/priorities.py", line 52, in addItem
item = Priority(subject = g.textBox.get("1.0", 'end-1c'), priority = g.textBox.get("1.0", 'end-1c'))
AttributeError: 'GuiPart' object has no attribute 'textBox'

Evo šta sam uradio:

Code:
# priorities.py
#   GUI program to manage priorities

from tkinter import *

class Priority:

    def __init__(self, subject, priority):
        self.subject = subject
        self.priority = priority

    def subject(self):
        return self.subject

    def priority(self):
        return self.priority

class GuiPart:

    def __init__(self):
        self.root = self.createWindow()

    def createWindow(self):

        root = Tk()
        root.resizable(width = False, height = False)
        root.title("Priorities")

        return root

    def createWidgets(self):

        Button(self.root,
               text = "Add",
               command = self.addItem).grid(row = 2, column = 0, sticky = W + E)

        Button(self.root,
               text="Remove",
               command = self.removeItem).grid(row = 2, column = 1, sticky = W + E)

        Button(self.root,
               text="Edit",
               command = self.editItem).grid(row = 2, column = 2, sticky = W + E)

        listBox = Listbox(width = 30).grid(row = 1, sticky = W + E, columnspan = 3)

        textBox = Text(height=5, width=30).grid(row = 3, columnspan = 3, sticky = W + E + N + S)

    def addItem(self):
        item = Priority(subject = g.textBox.get("1.0", 'end-1c'), priority = g.textBox.get("1.0", 'end-1c'))

        g.listBox.insert(END, item)

    def removeItem(self):
       pass

    def editItem(self):
        pass

class Client:
    pass

if __name__ == "__main__":
    g = GuiPart()
    g.createWidgets()
    g.root.mainloop()
