QTreewidgetitem not shown in QTree Widget

[A Former User]

Hi All,

I have a Qtreewidget named treewidget in my UI. I am adding another qtreewidget named temptree that will copy selective items from treewidget to temptree. The code is compiling fine but I am unable to see any item in temptree. Following is my code:

in the constructor I have set temptree->hide();
And in the fuction to copy treewidget to temptree:
@void ImageVideoManagerWidget::on_pushButton_clicked()
{
temptree = new QTreeWidget();
ui->verticalLayout->addWidget(temptree);
ui->widget_2->setLayout(ui->verticalLayout);
temptree->setMaximumSize(520,550);
temptree->setMinimumSize(520,550);
temptree->setIndentation(10);
temptree->setColumnCount(5);
temptree->setColumnWidth(0,120);

QStringList list;
list<<"Image"<<"TimeStamp"<<"Source"<<"Width"<<"Height";
temptree->setHeaderLabels(list);
temptree->clear();

//ui->slidertree->show();

// ui->slidertree->clear();
int time = ui->timeslider->value();
qDebug()<<time;
QTreeWidgetItem *item;

int j=0;
int flag=0,ok;
//settree_show();
settree_hide();

   // int time = ui->timelabel->text().toInt(&ok,10);
for( j=0;j<ui->treeWidget->topLevelItemCount();j++)
{
    item = ui->treeWidget->topLevelItem(j);
    qDebug()<<"here in loop 1";
    if(time<=item->toolTip(1).toInt())
    {
        flag = 1;
        qDebug()<<"here in loop 1"<<item->toolTip(1)<<flag;
        break;
    }
}
qDebug()<<"here out loop 1"<<item->childCount();
if (flag ==1)
for( j=0;j<item->childCount();j++)

{
    //qDebug()<<"here in loop 2"<<item->child(j)->toolTip(1);
    if(time<=item->child(j)->toolTip(1).toInt())

    {   qDebug()<<"here in loop 2"<<item->child(j)->toolTip(1);
        flag=2;
        item=item->child(j);
        break;
    }

}
qDebug()<<"here out loop 2"<<flag;
if (flag ==2)
for(int k=0;k<item->childCount();k++)
{
    qDebug()<<"in loop 3"<<item->child(k)->toolTip(1).toInt();
    if(time<=item->child(k)->toolTip(1).toInt())
    {
    flag =3;
    qDebug()<<"here in loop 3"<<item->child(k)->toolTip(1);
    item=item->child(k);
    break;
    }
}

j=0;
if (flag ==1)
    {
    qDebug()<<"here in loop 4";
    if(time==item->toolTip(1).toInt())
    temptree->insertTopLevelItem(0,item);
    }
else
for(int i=0;i<item->childCount();i++)
{

   if(time==item->child(i)->toolTip(1).toInt())
   {
       //ui->image_view->setText(item->child(i)->text(1));

    temptree->insertTopLevelItem(0,item->child(i));
    //temptree->setHidden(false);
    qDebug()<<"here in loop 5";
   }
}

temptree->show();
qDebug()<<"here out loop 5";

}@

Can some one please help me in deciphering where the error is??
