Hi, when i change
class A(QtGui.QMainWindow):
....
def setupUI(self):
self.lineEdit = QtGui.QLineEdit()
self.b = B()
self.b.c.clicked.connect(self.handleLetter)
...
def handleLetter(self):
self.lineEdit.setText("Hello")
there is no compilation or running error. But, lineEdit text doesn't
change, nothing happening.
