[Qt-interest] QModelIndex from internal pointer in QAbstractItemModel

[Simon Drouin]

Hi all,

I have a custom tree structure that I want to show in a QTreeView. I store
the elements of the tree (pointers to MyTreeItem in the example bellow) in
the internal pointer of QModelIndex. Now, how do I get the QModelIndex that
contains a specific element of my tree. I other words:

MyTreeItem * item;
QModelIdex index = ItemToIndex( item );

how do I implement the ItemToIndex function?

Thanks in advance.
