/#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <QToolButton>
MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);
    setFixedSize(1333,768);


        QComboBox *comboBox = new QComboBox(this);
        comboBox->addItem(tr("Automatic"));
        comboBox->addItem(tr("Manual"));
        comboBox->addItem(tr("Off"));

        QComboBox *iconComboBox = new QComboBox;
        iconComboBox->addItem(QIcon(":/icons/engranaje.png"), tr("Automatic"));
        iconComboBox->addItem(QIcon(":/icons/s_mano.png"), tr("Manual"));
        iconComboBox->addItem(QIcon(":/icons/s_off.png"), tr("Off"));

        connect(comboBox->tr(),SIGNAL(triggered()),this,SLOT(slotTest())); //<-- how can i make this?
}
//************************************************
void MainWindow::slotTest(){

}

The QComboBox provides signals such as currentIndexChanged() and currentTextChanged() that you can use for this purpose. The parameters passed are either the index of the element in the combobox or the item text.

You would do something like:

connect(comboBox, SIGNAL(currentTextChanged(QString)), this, SLOT(comboboxItemChanged(QString)));

I hope that helps.
