[FIXED] How to clear QLineEdit without triggering signal

Issue

QLineEdit triggers a signal on .clear() or .setText() method. So every time those methods are used to stop LineEdit from emitting the signal I need to .blockSignals(True) and then .blockSignals(False). I wonder if there is a way around it?

from PyQt4 import QtCore, QtGui    
app = QtGui.QApplication([])

class LineEdit(QtGui.QLineEdit):
    def __init__(self, *args, **kwargs):
        super(LineEdit, self).__init__()
        self.setText('Some Text')
        self.textChanged.connect(self.printMessage)
        self.show()
    def printMessage(self):
        print 'Triggered!'

line=LineEdit()
line.clear()
sys.exit(app.exec_())

Solution

Have you considered QLineEdit::textEdited? It doesn't emit signals when the text is changed programatically.
