It is purely a syntactic simplification, the behavior is identical +to specifying the property by name, but it can add a more natural feel in many +situations. The default property must be either an object or list property. + +Running the Example +------------------- + +The main.py file in the example includes a simple shell application that +loads and runs the QML snippet shown below. |
