TkClassWizard (1.4.10)#

TkClassWizard - define objects graphically based on class annotations. The library allows users to create abstract “ObjectInfo” objects based on the class’s parameters, which can later be converted to real Python objects and vice versa.

Installation#

TkClassWizard can be installed though command prompt/terminal using the bottom commands.

Pre-requirement: Python (minimum v3.9)

pip install tkclasswiz
