Remove duplicated object model in QML

XMLWordPrintable

    • Remove the duplicated object model from QML

      Currently, QML duplicates data from Qt's meta object model in its own datastructures for performance reasons.

       

      To avoid this overhead, we need to make the core data structures suitable for QML.

        1.
        		 Add QMetaType accessor for return and argument type to QMetaMethod Sub-task Closed Fabian Kosmale
        2.
        		 Extend QMetaObject to store whether property is alias or var property Sub-task Closed Fabian Kosmale
        3.
        		 Adapt declarative to further metaobject changes Sub-task Closed Fabian Kosmale
        4.
        		 Refactor and cleanup QMeta* classes Sub-task Closed Fabian Kosmale
