Drop From QML to QTreeView

[giupigna]

I have a QTreeView with a QStandarditemModel as model and actually I enabled the Drag&Drop on the tree's items.

Now I want to drop a element from a QML scene (I created the mimedata for the QML element) into the tree, but I'm unable to do it.

I overrided the flags method

Qt::ItemFlags TreeModel::flags(const QModelIndex &index) const
{
    if (index.isValid()) {
        return QStandardItemModel::flags(index);
    }

    return QStandardItemModel::flags(index) | Qt::ItemIsDropEnabled;
}

Also with simple text, if I drop it into the tree, I don't see the drop icon.

Hi
QTreeView also requires you to enable drops in the view. Did you do this ?

view->setAcceptDrops(true); 

Also I noticed that you only return the ItemIsDropEnabled flag if your index is invalid, you may have missed a ! in your test (unless you only want to accept drops on the root item). Put a breakpoint at the start of the TreeModel::flags function and see if it breaks to make sure that the view actually asks the model if a drop is available.
