12.1.10.8.23. Stylesheet editor

GUI for live coding of a Qt stylesheet document.

This GUI can be used to live adjust a qss stylesheet and directly see the changes for many widgets (Qt and itom specific).

Usage:

Execute this script to load the demo GUI. This GUI consists of a stylesheet editor widget in a left toolbar and many widgets, that are often used within itom.

If you stylesheet depends on icons within a rcc resource file, click the “load resources” button to load icons from a rcc resource file, first. Then paste your desired stylesheet into the editor. Whenever you want to update the GUI click the update button.
