tkinter course

Desktop apps with Python: every tkinter and ttk component, from labels to data tables, with the real window.

In DMarlon Studio, tkinter is the Desktop (Python) target: drag components from the palette onto the form, set their properties in the inspector and the studio writes this same tkinter code.
