* Unify "variant" and "var" properties in QMLFabian Kosmale2020-08-241-1/+1
| | | | | | | | | | | | | | | | | | | | variant and var properties differ in two important ways: - variant properties trigger "magic" string conversions: variant v1: "red" // contains a QColor var v2: "red" // contains a string - variant properties behave differently for value types: they create copies, instead of references. However, as variant properties were marked as obsolete and this behavior was effetively undocumented, it should be safe to give "variant" "var semantics". With this change, we can also avoid doing magic conversions when storing data in QVariant properties of QObjects/QGadgets Change-Id: I549b1beb98e6af9639c1ee81f316bda513d5ff65 Reviewed-by: Lars Knoll <lars.knoll@qt.io> Reviewed-by: Ulf Hermann <ulf.hermann@qt.io>

* | Use QTypeRevision for all versions and revisionsUlf Hermann2020-02-032-25/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In many places we carry major and minor versions or revisions that are loosely coupled to minor versions. As the Qt minor version resets now, we need to handle these things more systematically. In particular, we need to add a "major" part to revisions. QTypeRevision can express the current major/minor pairs more efficiently and can also be used to add a major version to revisions. This change does not change the semantics, yet, but only replaces the types. Change-Id: Ie58ba8114d7e4c6427f0f28716deee71995c0d24 Reviewed-by: Fabian Kosmale <fabian.kosmale@qt.io>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ChangeLog][QtQml] "required" is now a (contextual) keyword in QML, and users can mark properties with it to specify that those properties must be set when the component gets instantiated. This can be done either declaratively via standard property bindings from QML, or imperatively by using the functions to set initial properties (QQmlCompoent::setInitalProperties and related functions in C++, Qt.createObject, Loader.setSource,... in QML/JS). Logic has been added to QQmlComponent::create and the various QQmlIncubator classes to verify that the required properties were set. If properties marked as required are not set, a warning will be printed at runtime, and the component will not be created.
