The Tkinter Entry Widget Insertion Cursor

Question

I'm trying to implement autocompletion for Entry widget (or, rather, enhance the recipies already published by others). I want to make pop up appear next to insertion cursor. The problem is, I cannot find how to get the x/y coordinates of insertion cursor.

There is a similar question: The Tkinter Text Widget Insertion Cursor -- but it gives an answer for Text widget, which does not work for Entry.

Answer 1

The underlying Tk Entry widget has a bbox subcommand to get the coordinates of a specified item, as do Text and a few other widgets, but for some reason Tkinter fails to implement it on this particular widget. (If you do try calling .bbox() on an Entry , you're actually executing .grid_bbox() , which is something quite different.) However, you can usually work around missing Tkinter functionality by calling Tk directly:

entry._getints(entry.tk.call((entry, 'bbox', 'insert')))

(You can replace 'insert' with various other forms of character index specification.)
