Item insertion problem in QTreeWidget

[anuj]

Hi Experts,
I am inserting items in QTreewidget at top level using below function :
InsertFile(QString filepath)
{
QTreeWidgetItem *NewItems=new QTreeWidgetItem(ui->treeWidget);
NewItems->setText(0,filepath);
ui->treeWidget->addTopLevelItem(NewItems);
//ui->treeWidget->update();
}
After insert some item in Qtreewidget when i call this function another time then
files are not inserted at top level of tree.
File is inserted below the existing item and there is one row gap between them

My problem is how remove the empty row.And Insert item continue.
![enter image description here][1]

If i delete item from Qtreewidget , item is remove but index is not free.
QTreeWidgetItem *item;
QList<QTreeWidgetItem *> list;
list = ui->treeWidget->selectedItems();
if(list.count())
{
ui->treeWidget->selectedItems().clear();
item=list.takeFirst();
delete item;
}

Most probably InsertFile(QString filepath) is called with empty string.

QTreeWidgetItem *item;
QList<QTreeWidgetItem *> list;
list = ui->treeWidget->selectedItems();
if(list.count())
{
    ui->treeWidget->selectedItems().clear();
    item=list.takeFirst();
    delete ui->treeWidget->takeTopLevelItem(ui->treeWidget->indexOfTopLevelItem(item));
}

QTreeWidgetItem *item;
QList<QTreeWidgetItem *> list;
list = ui->treeWidget->selectedItems();
if(list.count())
{
    ui->treeWidget->selectedItems().clear();
    item=list.takeFirst();
    delete ui->treeWidget->takeTopLevelItem(ui->treeWidget->indexOfTopLevelItem(item));
}
