“项目。 ttk.Treeview（）。insert（）找不到”

Question

I'm trying to insert items in a tkinter treeview with five columns. I'm using this line of code:

self.resultsTable.insert(parent=self.parent, index='end', values=['1','2','3','4','5'])

However, the interpreter shows the following:

Exception in thread Thread-3:
Traceback (most recent call last):
  File "C:\Python34\lib\threading.py", line 920, in _bootstrap_inner
    self.run()
  File "C:\Python34\lib\threading.py", line 868, in run
    self._target(*self._args, **self._kwargs)
  File "C:\Users\gigi\Desktop\me\projects\PyMusic\test\threaded_test.py", line 166, in searchMusic
    self.showResults()
  File "C:\Users\gigi\Desktop\me\projects\PyMusic\test\threaded_test.py", line 111, in showResults
    self.resultsTable.insert(parent=self.parent, index='end', values=['1','2','3','4','5']) # values=song['details']
  File "C:\Python34\lib\tkinter\ttk.py", line 1337, in insert
    res = self.tk.call(self._w, "insert", parent, index, *opts)
_tkinter.TclError: Item . not found

I searched a lot on the web for a solution, but I couldn't find one. Is there anyone experienced with tkinter who can help me?

Answer 1

My guess is that your self.parent represents the root window, which has a string representation of ".". The tree is telling you that it doesn't have any items in the tree with an id of "." .

The first argument to insert is not a widget. It should be either the empty string -- which represents the id of the root item in the tree -- or the id of a previously inserted item.
