Qt Style Sheet Inspector

An inspector widget to view and modify the style sheet of a Qt app at runtime.

Usage

In order to use the inspector widget on your application, it's necessary to initialize the class style_sheet_inspector_class passing the instance of the QMainWindow from the application.

The repository demo_qt_inspector contains a full example of a Qt Application with an inspector widget being called by a shortcut action.

See the demo in action:

Features

View current style sheet of an application during runtime

The inspector only checks for style sheets that were applied to the QApplication, it's the topmost and any change here can be propagated to all children.

Style sheets that applied to an individual widget will not appear on the inspector.

Style sheet can be changed at runtime (Pressing CTRL+S)

Search bar to help find specific types or names (Pressing F3)

Can undo/redo changes (Pressing CTRL+ALT+Z or CTRL+ALT+Y)

Observation

It needs PyQt5 to work, but it doesn't have it as a dependency.
