Add support for registering value type to QML engine

XMLWordPrintable

      Introducing qmlRegisterValueType() would be very useful under some circumstances and may unify the built-in types implementation in current QML engine, e.g:

      // MyControl.qml

      import QtQuick 2.12
import QtQuick.Controls 2.12 as C

Item {
    property C.IconValueType icon
}

      We can also use the constructors that are marked with Q_INVOKABLE to initialize a value type property:

      import QtQuick.Controls 2.12 as C

MyControl {

    icon: "icon1" // implicit type casting provided by constructor

    // a better Qt.icon() approach
    Component.onCompleted: icon = new C.IconValueType("icon2", 16, 16)
}
