setIcon not working in QTreeWidgetItem?

[vinayaka]

Hai,

for(int i=0; i<3; i++)
       {
            QStringList strings;
            strings << QString("Wit Name");
            QTreeWidgetItem *parent = new QTreeWidgetItem(strings);
            ui->firstTreeWidget->addTopLevelItem(parent);
            parent ->setIcon(0,QIcon(QString::fromUtf8(":/images/heart.ico")));
            QTreeWidgetItem *child = new QTreeWidgetItem;
            parent->addChild(child);
            ui->firstTreeWidget->setItemWidget(child, 0, new QLineEdit(ui->firstTreeWidget));
       }

for(int i=0; i<3; i++)
       {
            QStringList strings;
            strings << QString("Wit Name");
            QTreeWidgetItem *parent = new QTreeWidgetItem(strings);
            ui->firstTreeWidget->addTopLevelItem(parent);
            parent ->setIcon(0,QIcon(QString::fromUtf8(":/images/heart.ico")));
            QTreeWidgetItem *child = new QTreeWidgetItem;
            parent->addChild(child);
            ui->firstTreeWidget->setItemWidget(child, 0, new QLineEdit(ui->firstTreeWidget));
       }
