CTkCombobox index and delete methods

[adriaandb]

I am looking for a way to get the index from a CTkCombobox, so i can call an object from a list parallel to the combobox entries. But I see .current or so is not configured. Is there any other way/method to retrieve the index int from a CTkCombobox?
Also looking for a way to refresh the combobox as .delete or .entry.delete doesnt seem to be callable..
