          @Gelo Check this example:
          https://www.tutorialspoint.com/pyqt/pyqt_signals_and_slots.htm

          In the similar way you connect to the currentIndexChanged signal and get the selected index text in the connected slot.

                @Gelo Sure but first you must become familiar with Qt's Signals and slots mechanism.

                  self.comboBox.currentIndexChanged.connect(self.selectionchange)
                  #
                  while(self.query.next()):
                  self.comboBox.addItem(self.query.value(0).toString())
