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.

Why don't you pass a reference of the main windows to your's subclass?
Because i am newbie :)
I am so pleased with all of your replies. This answer solve my problem.
I have one question more. Why this is useless:
class A(QtGui.QMainWindow):
....
def setupUI(self):
self.lineEdit = QtGui.QLineEdit()
self.b = B()
...
def handleLetter(self):
self.lineEdit.setText("bla bla") # ---> Notice:
Difference is here
class B(QtGui.QWidget):
....
def setupUI(self):
self.C = C()
...
class C(QtGui.QPushButton):
def __init__(self, parent, letter):
self.clicked.connect(A.handleLetter) # ---> Notice: Another
difference
I get this error:
self.clicked.connect(A.handleLetter)
AttributeError: 'function' object has no attribute '__pyqtSignature__'
