[Qt-interest] not able move across elements in QTreeWidget

[Sujan Dasmahapatra]

Andre  I am loading only 2 items they're text, one item is a child of
another. trying to move my cursor between them  selecting them but when
after some time this causes to get stuck and i cannot move anymore.I need to
close the application and restart again. same thing is happening again.

See the code snippet below.
I can see the items are loaded in the treewidget but the move moments are
not free.

///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
QList <QTreeWidgetItem  *> item;
item.append(new QTreeWidgetItem(this));
item[0]->setText(0,"part1");
QTreeWidgetItem *partname = new QTreeWidgetItem(item[0]);
partname->setText(0,"child");
item[0]->addChild(partname);
//////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
