You can add "[Solved]" to the topic yourself, just hit the edit link to the right of the first post in the thread and adjust the title. You also may add a tag "solved".

Do you mean that you solved the issue, or that you still want somebody to look at it?

i meant that i still want someone to look at it. i really need an example for this topic.

Here is a code snippet that should get you going. At first, i thought you wanted a context menu on the actual list dropping down, but after re-reading, I figure that you want to extend the menu on the line edit part. Here is some code doing that. Note that it only works for editable comboboxes. For non-editable ones, it will crash.
The header that goed with it is trivial, so not shown.
@
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
qDebug() << "Current context menu policy:" << ui->comboBox->contextMenuPolicy();ui->comboBox->setContextMenuPolicy(Qt::CustomContextMenu); m_deleteAction = new QAction(tr("Delete item"), this); connect(m_deleteAction, SIGNAL(triggered()), this, SLOT(deleteItem())); connect(ui->comboBox, SIGNAL(customContextMenuRequested(QPoint)), this, SLOT(contextMenuRequest(QPoint)));
}
MainWindow::~MainWindow()
{
delete ui;
}void MainWindow::deleteItem()
{
qDebug() << "we should delete this item";
}void MainWindow::contextMenuRequest(QPoint pnt)
{
QMenu* menu = ui->comboBox->lineEdit()->createStandardContextMenu();
menu->addSeparator();
menu->addAction(m_deleteAction);
menu->popup(pnt);
connect(menu, SIGNAL(aboutToHide()), menu, SLOT(deleteLater()));
}

thank you Andre. the code works perfectly :)
i hope this topic helps others. i had a minor problem. the menu was displayed at the top left corner of the screen. see the below code for the fix.
replace the first line of code with the second line of code.
@menu->popup(pnt);
menu->popup(QCursor::pos());@Edit: I am using vista

Code worked for me without modification (windows 7), but I am glad you got it sorted.
