pyui.create_list_box
Create a list box for the user to select one of multiple options. Use insert_control_item to populate the list box with options and reset_content to clear the list box. Call set_control_selection to initialize the selection status.
Note that radio buttons and drop lists are another way to present multiple options to the user.

The length of a list box is calculated from the number of adjacent rows. Fine-tuning of the length can be achieved by inserting alignments and empty elements.
When the user changes the selected option of a list box, the on_change handler is called on_change_handler(text, new_index) with one string argument of the selected text and one integer argument for the index of the newly selected option.
