QAbstractScrollArea::setHorizontalBarPolicy updates the listWidget in bad Way

[leonardoMB]

listWidget->setHorizontalScrollBarPolicy(Qt::ScrollBarAsNeeded);

Currently my code is like this and and I Have a splitter, but if I move the split to the point that I don't need more the scroll, the list is updated in the sense that if I were at the line 450, the list goes up to the line 1. How avoid such behavior?

The widget below does not display the behaviour you describe.

#include "widget.h"

#include <QListWidget>
#include <QSplitter>
#include <QTextEdit>
#include <QVBoxLayout>

Widget::Widget(QWidget *parent)
    : QWidget(parent)
{

    QListWidget *list = new QListWidget(this);
    list->setHorizontalScrollBarPolicy(Qt::ScrollBarAsNeeded);  
        // ^^^ this is the default in many styles anyway
    QString entry;
    for (int row = 0; row < 10; ++row) {
        entry.append("word ");
        list->addItem(QString("Row %1 %2").arg(row).arg(entry));
    }

    QTextEdit *edit = new QTextEdit(this);

    QSplitter *splitter = new QSplitter(this);
    splitter->addWidget(list);
    splitter->addWidget(edit);

    QVBoxLayout *layout = new QVBoxLayout(this);
    layout->addWidget(splitter);
}

Widget::~Widget()
{
}

Before

After stretching horizontally

Row 2 stays where it was after the horizontal scroll bar disappears.

@ChrisW67 You are right, I was setting an ItemUpdate after the Splitter resize through setResizeMode(QListWidget::Adjust), it was causing my bad behavior, after removing no problem was encountered
