Need help in getting my combination of strings from treeview column into textbox-CodePudding

I am trying to get the text inside my Address column which contains a combination of string fetched from mysql into the tkinter text box but it returns error. Can anyone help me?

fetching from sql

_sql = "SELECT * FROM customers"
_val = None
custs = sql.fetchAll(_sql,_val)
if custs != None:
    for i, (id,name,address1,address2,address3,address4,phone,email,birthdate) in enumerate(custs, start=1):
        listBox.insert("","end",values=(id,name,address1 ", " address2 ", " address3 ", " address4,phone,email,birthdate))

my treeview code:

cols=('ID','Name','Address','Phone','Email','Birthdate')
listBox=ttk.Treeview(listFrame, columns=cols, show='headings',height=36)
for col in cols:
listBox.heading(col, text=col)
listBox.grid(row=1,column=0,columnspan=2)
listBox.column(col,minwidth=0,width=262,stretch=NO,anchor=CENTER)
listBox.place(x=30,y=173)
listBox.bind('<Double-Button-1>',self.selectCust)

textbox code:

e2=Text(listFrame,fg="#18191b",bg="#fbb913",width=20,borderwidth=0,highlightthickness=0,height=5,wrap=WORD)
e2.place(x=100,y=52)

trying to insert strings from address column to textbox:

e2.insert(0,sel['Address'])

error output:

Exception in Tkinter callback
Traceback (most recent call last):
  File "C:\Users\user\AppData\Local\Programs\Python\Python39\lib\tkinter\__init__.py", line 1892, in __call__

_tkinter.TclError: bad text index "0"

CodePudding user response：

Tkinter Text objects accept indexes in the form "<line>.<character>", so the first line, first character would be represented as "1.0". The second line, first character would be "2.0", the fourth line, ninth character would be "4.8" and so on.

In this case, you could change the problem line to:

e2.insert('1.0', sel['Address'])
