* Use QTaggedPointer in QPropertyObserverSimon Hausmann2020-03-194-78/+70
| | | | | | | | | | This replaces the private tagged pointer and the use of enums for the tag makes the observer handling code more readable. The pointer-to-tagged-pointer class remains in qpropertyprivate.h due to its exoticness. Change-Id: Icc88799136c6839426d994b42368526463265e66 Reviewed-by: Fabian Kosmale <fabian.kosmale@qt.io>

| | | | | | | | | | A generic binding allows implementing the binding function in a way that enables the QML engine to run binding scripts and convert the V4::Value into a QVariant and then assign the value to the property with the help of QMetaType::construct.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QtDeclarative registers types in plugins, and supports un- and reloading those plugins. Those types would leave pointers to unmapped memory in the type registry on macOs, which would later cause crashes. We therefore add private API to manually remove the types from the registry, which can then be used in declarative. Lastly, as a precaution for re-registering the types, we reset QMetaTypeInterface::typeId to 0, as the memory is most likely not reset to 0 when reloading the plugin.

* | | New QMetaType representationOlivier Goffart2020-02-203-1361/+528
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | the QMetaType is represented as a pointer to a "vtable" in the form of a QtPrivate::QMetaTypeInterface* The recomanded use of QMetaType is to construct an object with QMetaType::fromType. This does not require any registration. There is still an id() function which will do some registration for compatibility with Qt5. Also the patch does not really touch the other extra things that can be registered (data stream operator, comparison operator, iteratable, ...) and this still uses the previous system. This is only the change in QMetaType, other changes to use it in QVariant and QMetaObject will follow Change-Id: Iffad20085cf33f33447f58a68236013a8b60fdbf Reviewed-by: Simon Hausmann <simon.hausmann@qt.io>
