Hi. i have a treeview. What I need is to hide parents if they don't match but their child do. As I guess it leads to tree reconstruction - changing parent of visible children. How is it better to do it?
Currently I have this, but of course it does show parents if children matches

Qt Code: 
  1. bool TreeFilteredModel::filterAcceptsRow(int sourceRow, const QModelIndex &sourceParent) const
  2. {
  3. 	bool ret = false;
  4. 	QModelIndex subIndex = sourceModel()->index(sourceRow, 0, sourceParent);
  5. 	WorkflowTreeItem* item = (WorkflowTreeItem*)subIndex.internalPointer();
  6. 	int childCound = sourceModel()->rowCount(subIndex);
  7. 	if (subIndex.isValid())
  8. 	{
  9. 		for (int i = 0; i < childCound; ++i)
  10. 		{
  11. 			ret = ret || filterAcceptsRow(i, subIndex);
  12. 		}
  13. 	}
  14. 	ret |= (item->command()->getName().contains(m_commandSearchParameter, Qt::CaseInsensitive) && item->command()->getName().contains(m_textSearchParameter, Qt::CaseInsensitive));
  15. 	return ret;
  16. }
