Not able to see plus sign even if I pass true from hasChildren function in Qt

Hi,
I am implementing tree view, I have sub classed my model and view. initially I am populating all the top level items and I don't know how many child's are there for each top level items but I know all the top level items has a child's, so I have re-implemented hasChildren() function and pass true for all the top level items, but I am not able to see + sign for the top level items even i pass true. Please let me know the problem

Thanks in advance.

Have you tried your model with the standard tree view?
Have you tried your view with an existing tree model, e.g. QFileSystemModel?

I have customized my view and model both.

re implemented QTreeView & QAbstractItemModel.

Yes, you already wrote that.

I have tried my model with Qtreeview and my view with QStandardItemModel. I could see same result.

So if you have a QStandardItemModel, you are not seeing any expand indicators either?

Just to verify: using that model with a QTreeView works, right?
