How to count number of visible children in a QTreeWidget

[bday1223]

Hello,

I'm trying to determine the number of visible child items in a QTreeWidget (e.g. if the bottom-level children are visible, not collapsed and hidden). So far, I've not had any luck. All elements of the tree are simple top level nodes with children.

// count a the number of visible items
QTreeWidget* tree = current_tree();
int num_visible = 0;
for (int ii = 0; ii < tree->topLevelItemCount(); ii++)
{
    QTreeWidgetItem* top_item = tree->topLevelItem(ii);

    if (top_item->isExpanded())
    {
        num_visible += top_item->childCount();
    }
}

Anyone have a simple solution?

Many thanks,
BD

Hi,

The visualRect method comes to mind for that.
