Long live QML inline components
[ChangeLog][QtQml] It is now possible to declare new QML components in
a QML file via the component keyword. They can be used just as if they
were declared in another file, with the only difference that the type
name needs to be prefixed with the name of the containing type outside
of the file were the inline component has been declared.
Notably, inline components are not closures: In the following
example, the output would be 42
// MyItem.qml
Item {
property int i: 33
component IC: Item {
Component.onCompleted: console.log(i)
}
}
// user.qml
Item {
property int i: 42
MyItem.IC {}
}
Fixes: QTBUG-79382
