QTreeWidgetItem

[raphaelf]

Hello everybody
QT:4.1.1

I have a QTreeWidget where i can see my database and the tables of this.
I was able to implement it. But i get a item there that i dont need (Please see picture).
I dont need the selected one (picture).

Can somebody see what is wrong on my code:

ui.tree->clear();
		ui.tree->setObjectName(QLatin1String("ui.tree"));
        ui.tree->setHeaderLabels(QStringList(tr("database")));
       // ui.tree->header()->setResizeMode(QHeaderView::Stretch);
 
		QTreeWidgetItem *root = new QTreeWidgetItem(ui.tree);
		root->setIcon(0, QIcon(QString::fromUtf8(":/images/images/database.jpg")));
		root->setText(0, "inventar");
 
		QTreeWidgetItem *tables = new QTreeWidgetItem(root);
		tables->setIcon(0, QIcon(QString::fromUtf8(":/images/images/new.png")));
 
	QSqlQuery select("select * from sysobjects where xtype = 'U' order by name");
	while(select.next())
	{
		QStringList tabelle = select.value(0).toStringList();
		new QTreeWidgetItem(tables, tabelle, 0);
 
	}

ui.tree->clear();
		ui.tree->setObjectName(QLatin1String("ui.tree"));
        ui.tree->setHeaderLabels(QStringList(tr("database")));
       // ui.tree->header()->setResizeMode(QHeaderView::Stretch);
      
		QTreeWidgetItem *root = new QTreeWidgetItem(ui.tree);
		root->setIcon(0, QIcon(QString::fromUtf8(":/images/images/database.jpg")));
		root->setText(0, "inventar");
		
		QTreeWidgetItem *tables = new QTreeWidgetItem(root);
		tables->setIcon(0, QIcon(QString::fromUtf8(":/images/images/new.png")));
		        
	QSqlQuery select("select * from sysobjects where xtype = 'U' order by name");
	while(select.next())
	{
		QStringList tabelle = select.value(0).toStringList();
		new QTreeWidgetItem(tables, tabelle, 0);
		
	}

Don't create the "root" element.

of course
thanks..
Wysota how could i set a icon for every items in my list (parent tables):

while(select.next())
	{
		QStringList tabelle = select.value(0).toStringList();
		new QTreeWidgetItem(tables, tabelle, 0);
 
	}

while(select.next())
	{
		QStringList tabelle = select.value(0).toStringList();
		new QTreeWidgetItem(tables, tabelle, 0);
		
	}

how to set a icon for every items in my list (parent tables)

Exactly the same way you set the icon for the root/table item.

QTableWidgetItem* item = new QTreeWidgetItem(tables, tabelle, 0);
item->setIcon(..);

QTableWidgetItem* item = new QTreeWidgetItem(tables, tabelle, 0);
item->setIcon(..);
