Python Spinbox example

Change spinbox increment value programmatically from 10 cents to 1 cent, using control click arrow up or down. Format for 8 characters and 2 decimal places, this should be include otherwise you can get different numbers.

 Please comment below if you have a better way of doing the same basic thing. please see link below for other example using a combobox
