iblqt.tools.run_as_qt_app(function)

Run a function as a Qt application.

This decorator wraps a function that returns a QWidget (or subclass) to be used as the main widget of a Qt application. It ensures a QApplication instance is created (or retrieved if already existing), calls the function to get the widget, and then starts the Qt event loop.

Parameters:

function (Callable[..., QWidget]) – A function that returns a QWidget instance to be shown as the main widget of the Qt app.

Returns:

A wrapped function that runs the Qt application event loop and returns its exit code.

Return type:

Callable[..., int]
