Python tkinter inserting string in texttbox out of a function
Question: Trying to add text from a function into a textfield, but can't figure out how.
Every time when the Start button is clicked it should add text to the
textfield.

    
    
    import Tkinter
    
    class GuiCreate:
    
        def __init__(self,parent):
    
            #Textbox
            window  = Frame(width=620, height=50)
            window.place(x=25,y=320)
            vscroll = Scrollbar(window)
            hscroll = Scrollbar(window, orient='horizontal')
            #  create instance variable with "self"
            self.listbox = Text(window, height=10) 
            self.listbox.pack(side=LEFT, fill=X, padx=5, pady=5, expand=1)
            vscroll.config(command=self.listbox.yview, relief=SUNKEN)
            hscroll.config(command=self.listbox.xview, relief=SUNKEN)
            self.listbox.config(yscrollcommand=vscroll.set, relief=SUNKEN)
            self.listbox.config(xscrollcommand=hscroll.set)
    
            f7 = Frame(width=30, height=20)
            f7.place(x=20,y=260)
            srcButton = Button(f7, text="START", command=self.startProcess)
            srcButton.pack(side='left')
    
    
        def startProcess(self):
            textinsert = 'abcdefg'
            self.listbox.insert('end', textinsert)
    
    
    root = Tk()
    root.title("Clipfinder")
    root.geometry('650x550+200+100')
    root.configure(background = 'gray')
    gui=GuiCreate(root)
    root.mainloop()
    

Getting the Error: AttributeError: GuiCreate instance has no attribute
'listbox'

How can I send the string out of a function into the textbox? THX


Answer: 
    def __init__(self, parent):
        #Textbox
        window  = Frame(width=620, height=50)
        window.place(x=25,y=320)
        vscroll = Scrollbar(window)
        hscroll = Scrollbar(window, orient='horizontal')
        self.listbox = Text(window, height=10)
        self.listbox.pack(side=LEFT, fill=X, padx=5, pady=5, expand=1)
        vscroll.config(command=self.listbox.yview, relief=SUNKEN)
        hscroll.config(command=self.listbox.xview, relief=SUNKEN)
        self.listbox.config(yscrollcommand=vscroll.set, relief=SUNKEN)
        self.listbox.config(xscrollcommand=hscroll.set)
    
        f7 = Frame(width=30, height=20)
        f7.place(x=20,y=260)
        srcButton = Button(f7, text="START", command=self.startProcess)
        srcButton.pack(side='left')
    

Forgot to add listbox as an attribute. Otherwise it is just local to the init
method..
