tkinter中text插入_pythonTkinter在函数的textbox中插入字符串

正在尝试将函数中的文本添加到textfield中，但无法确定如何添加。

每次单击开始按钮时，它都应该向textfield添加文本。在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()

获取错误：AttributeError:GuiCreate实例没有属性“listbox”

如何将函数中的字符串发送到文本框中？
