TkLineNums

TkLineNums is a simple line numbering widget for Python's tkinter GUI library. It directly connects to a Text widget and even supports ttk themes through the set_to_ttk_style() method.

Features of the TkLineNums widget:

Clicking on line numbers will set the insert to the beginning of the line.
Shift clicking will select all text from the end of the line clicked by cursor and the insert position.
Scrolling the line bar will scroll the text widget (and vice versa).
Supports ttk themes (by usage of the .set_to_ttk_style() method).
Supports left, right, and center alignment with the -justify option.
Clicking and then dragging the mouse will scroll the text widget (see #8).
