<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Yes. And the parent of a top level item is an invalid index.
If we look at rowCount we do:
if (parent.isValid) {return 0;}
we want to pass an invalid index to get the list row count.</pre>

If "rowCount(QModelIndex())" returns 0, "rowCount(QModelIndex())-1" is always "-1", or am I missing something?

If you pass invalid index to rowCount(), it counts the top-level items, which in this case they are all top-level, so it does not return 0, but the correct list size.</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">My code snippet is correct, but missing some stuff. Let me explain again.
our rowCount code says
if (parent.isValid()) {
return 0; //it must be a child item so we return 0 to show it's not a tree
} else {
return m_list.size(); //top level items
}
we want to get into the else statement, which means we need to pass an invalid index.</pre>
