Set Default Selected item for QCombox from QTreeWidget ( QTreeWidget is inside QCombobox )

[frsdot]

Hello,

I have set a qTreeWidget inside a QCombo box, it works well. But I am unable to add the default selected item ( say second item with column one's data).

Here is the code snippet

cmb = new QComboBox();
QTreeWidget *treeWidget = new QTreeWidget(cmb);
cmb->setModel(treeWidget->model());

treeWidget->setColumnCount(2);
QTreeWidgetItem *topLevelItem = NULL;

QTreeWidgetItem *parentItem = topLevelItem;

for( int row =0; row < 2; row++)
{

QPointer<QPushButton> SendBtn= new QPushButton("Send");

QTreeWidgetItem* item = new QTreeWidgetItem();
treeWidget->addTopLevelItem(item);

treeWidget->setItemWidget(item, 0, txtLabel); // Set lable
treeWidget->setItemWidget(item, 1, SendBtn); // Set push button.

}

treeWidget->header()->hide();
cmb->setView(treeWidget);

cmb->setModelColumn(0); // Set default text of selected item to column 1 i.e label data ?????????????
cmb->setCurrentIndex(1); // Select first row ???????????

Similarly when I use the signal slot mechanism to select an item from QTreeWidget and set inside QCombo box selected item , it does not work either for combo box.

connect(cmb, SIGNAL(activated(int)), this, SLOT(getComboIndex(int)));

void TestWidget:: getComboIndex(int index)
{
cmb->setModelColumn(1);
cmb->setCurrentIndex(index);
}

cmb = new QComboBox(this);

This does not work either. Moreover , I modified the code so that combo box is created in designer and I reference that combo box.

In the event
void TestWidget:: getComboIndex(int index)
{
cmb->setModelColumn(1);
cmb->setCurrentIndex(index);
}
treeWidget->currentIndex() --> This does return me a model index whose row and column correspond to the value selected from tree widget. But setting it in combo box seems to be an issue.
