QML recursive instantiation.

Jim Gir

Hi,
REcursive instantiation is not allowed in QML as I see. https://codereview.qt-project.org/c/qt/qtdeclarative/+/30237
But how to accomplish this ? :

# MyComp.qml
Item {
    Repeater {
       model : [somedata]
       delegate: MyComp{} 
   }
}

There is no risk of infinite recursion since instantiation is controlled by the model.

I would need it to build something like a tree.

Thanks for help
Jimmy

If this were allowed, just one item in your model would cause infinite recursion.

Long answer:
Build a model in C++ around a tree structure. Use the TreeView object to display this tree. Your MyComp.qml can be used as a delegate.
