Scroll-to-column in QTreeWidget?

[Santosh Reddy]

Try this, I have checked it works just fine.

QModelIndex computeModelIndex(QTreeWidgetItem * item, int column = 0)
{
    QModelIndex index;
 
    if(item == 0)
        return index;
 
    QTreeWidget * treeWidget = item->treeWidget();
 
    if(treeWidget == 0)
        return index;
 
    QTreeWidgetItem * parent = item->parent();
 
    if(parent)
        return computeModelIndex(parent, 0).child(parent->indexOfChild(item), column);
 
    return treeWidget->model()->index(treeWidget->indexOfTopLevelItem(item), 0);
}
 
//elsewhere
QModelIndex index = computeModelIndex(item, 9);
if(index.isValid())
    mTreeWidget->scrollTo(index);

QModelIndex computeModelIndex(QTreeWidgetItem * item, int column = 0)
{
    QModelIndex index;

    if(item == 0)
        return index;

    QTreeWidget * treeWidget = item->treeWidget();

    if(treeWidget == 0)
        return index;

    QTreeWidgetItem * parent = item->parent();

    if(parent)
        return computeModelIndex(parent, 0).child(parent->indexOfChild(item), column);

    return treeWidget->model()->index(treeWidget->indexOfTopLevelItem(item), 0);
}

//elsewhere
QModelIndex index = computeModelIndex(item, 9);
if(index.isValid())
    mTreeWidget->scrollTo(index);
