MSVC 2015 x64
Description
In Qt 5.11.1, using QtQuick.Controls 2.4, a ComboBox will crash the program loading it at startup if created this way:
ComboBox {
id: box
model: [ "Banana", "Apple", "Coconut" ]
}
A ComboBox will crash at startup if created this way:
ComboBox {
id: box
model: ListModel {
ListElement{ text: "Banana" }
ListElement{ text: "Apple" }
ListElement{ text: "Coconut" }
}
}
A ComboBox will crash when clicked if created this way:
ComboBox {
id: box
property var myListModel: ListModel {}
model: myListModel
Component.onCompleted: {
myListModel.append({rName: "Banana"})
myListModel.append({rName: "Apple"})
myListModel.append({rName: "Coconut"})
}
}
All examples above were working fine in Qt 5.10 and QtQuick.Controls 2.3. (Note that QtQuick.Controls 2.3 produce the same crashes in Qt 5.11.1).
Not adding any item to the ListModel do not cause any crash on click, but is not a workaround obviously.
Qml executed using the following C++ function and a Window item parent for the ConboBox:
myQQmlApplicationEngine->load(QUrl(qmlFilePath));
