The approach looks fine. As for combining two models - you'll have to "delegate" access to one model to the other. So for instance if someone asks your model for data for an index that describes a file in a project, you'll have to translate the index to an index understood by the dir model, call the dir model's method with this crafted index and return the result as a result of your method. A simple sketch of what I mean (look in my earlier post for an extended version):

QVariant MyModel::data(const QModelIndex &index, ...) const {
  QModelIndex dirIndex = translateToDirModel(index);
  return internalDirModel->data(dirIndex, ...);
}

QVariant MyModel::data(const QModelIndex &index, ...) const {
  QModelIndex dirIndex = translateToDirModel(index);
  return internalDirModel->data(dirIndex, ...);
}

Thanks Wysota,

I am finding difficult in "mapping the index (of my model) to index of dir model" and also finding the depth of an index. Somehow i managed to code for finding the depth of an index. I have attached the source code. Please verify the depth function and some more hints on mapping the index(i would request the complete code).

As I said earliar, i am using the simpletreemodel code. currently am hardcoded the values in setupModelData.

Thanks

Finding depth is easy. Just iterate to parent() index and count how many iterations it takes until you reach the top.

QModelIndex iter = index;
int depth = 0;
while(!iter.isNull()){
  iter = iter.parent();
  ++depth;
}

QModelIndex iter = index;
int depth = 0;
while(!iter.isNull()){
  iter = iter.parent();
  ++depth;
}
