Description
I believe there is a problematic behaviour in case of creation QGadget based class that holds:
Q_PROPERTY(QStringList gadgetStringList READ gadgetStringList WRITE setGadgetStringList)
There is no possibility in QML context to change elements of gadgetStringList by index gadgetStringList[i]:
Window {
property myTestGadget gadget
Component.onCompleted: {
gadget.gadgetStringList = ["Element1", "Element2", "Element3"]
obj.qobjectStringList = ["Element1", "Element2", "Element3"]
console.log("Gadget List: " + gadget.gadgetStringList)
console.log("Object List: " + obj.qobjectStringList)
gadget.gadgetStringList[0] = "Completely new Element"
obj.qobjectStringList[0] = "Completely new Element"
console.log("Gadget List: " + gadget.gadgetStringList)
console.log("Object List: " + obj.qobjectStringList)
gadget.gadgetStringList = ["Element4", "Element5"]
console.log("Gadget List: " + gadget.gadgetStringList)
}
}
Note: The same functionality for QObgect classes works correctly.
obj.qobjectStringList - QObject based list
gadget.gadgetStringList - QGadget based list{}
Actual result:
qml: Gadget List: Element1,Element2,Element3 qml: Object List: Element1,Element2,Element3 qml: Gadget List: Element1,Element2,Element3 qml: Object List: Completely new Element,Element2,Element3
Expected result:
qml: Gadget List: Element1,Element2,Element3 qml: Object List: Element1,Element2,Element3 qml: Gadget List: Completely new Element,Element2,Element3 qml: Object List: Completely new Element,Element2,Element3
Please, find full code version in attach.
Another important problem for QGadgets:
Q_PROPERTY(QByteArrayList gadgetArrayList READ gadgetArrayList WRITE setGadgetArrayList)
gadget.gadgetArrayList[0] is not recognised in QML
Note:
Again for QObjects everything works.
