Can't type in QlineEdit if the keyPressEvent is on

I am having a problem with the QLineEdit, if i enable the keyPressEvent in the code then i am not able to type anything in the QLineEdit.

class SearchBox(gui.QLineEdit):
    def __init__(self, parent=None):
        super(SearchBox, self).__init__(parent)

        self.setWindowTitle("Explorer")
        self.setGeometry(500,500,400,40)
        font = gui.QFont()
        font.setPointSize(15)
        self.setFont(font)

    # if i disable this function then it works..
    def keyPressEvent(self, event):
        if event.key() == core.Qt.Key_Escape:
            self.close()
        if event.key() == core.Qt.Key_Enter:
            print self.text()
            self.close()

can someone please help me with this.. thanks.

If you don't call the keyPressEvent of the base class how is it supposed to know that some key was pressed?

def keyPressEvent(self, event):
    if event.key() == core.Qt.Key_Escape:
        self.close()
    if event.key() == core.Qt.Key_Enter:
        print self.text()
        self.close()
    else:
        super(SearchBox, self).keyPressEvent(event)

This is also mentioned in the documentation:

If you reimplement this handler, it is very important that you call the base class implementation if you do not act upon the key.
