Thank you for your answer André.

My table proxy model is just giving the logic to show in the table view,
the children of the element clicked in the tree view doing the
following:

void WhchTableProxyModel::onItemClicked(const QModelIndex &index)
{
    emit retrieve_children(mapFromSource(index));
}

SOURCE:

So if we look again at the example I wrote:
--------
 | Root |
 --------
      |
      |__Year1
      |  |
      |  |__Week1
      |  |  |
      |  |  |__Day1
      |  |     |
      |  |     |_Task1
      |  |     |
      |  |     |_Task2
      |  |     |
      |  |     |_Task3
      |  |
      |  |__Week2
      |     |
      |     |__Day1
      |     |  |
      |     |  |_Task1


What happens is:
If I click on Year 1, then Week 1 and Week2 are displayed.
If I click on Week1, then Day 1 is displayed.
If I click on Day 1, then Task1, Task2 and Task3 are displayed.

So it just displays the leaf-nodes for the 'Day' elements, but what I
need is to display the leaf-nodes for 'Year', 'Week' and 'Day' elements,
and not just for the 'Day' elements. That means:

If I click on Year 1, display Task1, Task2, Task 3 and Task1.
If i click on Week 1, display Task1, Task2 and Task3.
If I click on Day1, display Task1, Task2 and Task3.

You said you found some code examples that could help and that I would
have to make some changes in my table proxy model, but I did not find
those examples and do not understand how can I make this happen. Could
you be a little bit more explicit please?. Or paste the link with the
example you saw?

Thank you in advance,
Patricia.
