Free Python document styling/stylesheet classes for Qt QGraphicsView

[bootchk]

See: https://github.com/bootchk/documentStyle

Example code and demo app.

It lets user edit stylesheets and style of document elements (QGraphicItems.)
The emphasis is on good object design for styling classes, e.g. Styleable, Stylesheet, Selector, StylingAct (aka Declaration.)
Includes GUI classes for styling e.g. StylingDialog.

In progress: buggy, and things to do.

Not about Qt Stylesheets for styling Widgets!
