QTreeWidget ui was not declared

[hacquerqop]

hey this is my code and It says that 'ui' was not declared

Dialog::Dialog(QWidget *parent) :
QDialog(parent),
ui(new Ui::Dialog)
{
ui->setupUi(this);

ui->treeWidget->setColumnCount(2); //and it says there is a problem there too about ->treeWidget must point to class/struct/pointer
AddRoot("hello", "world");
}

Dialog::~Dialog()
{
delete ui;
}


void AddRoot(QString name, QString description)
{
QTreeWidgetItem *itm = new QTreeWidgetItem (ui->treeWidget);

itm->setText(0, name);
itm->setText(1, description);
ui->treeWidget->addTopLevelItem(itm);

}

Did you add a QTreeWidget class instance into your Dialog.ui file named "treeWidget" when you used Qt Designer to define your dialog's UI?

And use CODE tags when posting source code. See my signature block below.
