Hi guys,
I'm using the provided QTreeModel. It works fine when using only the first
column.
But if I try to add data to a second column there is either the same data
displayed as in the first column or none at all.
So I had a look at the sources and found a part below that confuses me.
In the last line the index is created and the column is _always_ set to 0.
Is this a mistake or is the QTreeModel not supposed to hold more than one
column?
Regards,
Paolo
QModelIndex QTreeModel::index(int row, int, const QModelIndex &parent) const
{
Node *parentNode = node(parent);
// abstract item view may decide to ask for index(0, 0) even
// though it doesn't exist, as part of its sanity checking...
if (parentNode->nodes.size() == 0) {
return QModelIndex();
}
QTJAMBI_EXCEPTION_CHECK(qtjambi_current_environment());
if (!parentNode->isChildrenQueried())
queryChildren(parentNode);
QTJAMBI_EXCEPTION_CHECK(qtjambi_current_environment());
// So someone asked for a bad row... so what...
if (row >= parentNode->nodes.size())
return QModelIndex();
Q_ASSERT_X(parentNode->nodes.at(row),
"QTreeModel::indeX()",
"all child nodes must be queried ahead of time...");
return createIndex(row, 0, parentNode->nodes.at(row));
}
