What you see happens because you're not using the existing instance of Signals
, but you're creating a new one each time the button is clicked.
In your case, you could add a reference to the instance as an argument when you create the new window, so that you can correctly connect to its signal.
class Signals(QWidget):
# ...
def windown2(self):
self.ggpp = Main(self)
self.ggpp.show()
class Main(QWidget):
def __init__(self, signals):
super(Main, self).__init__()
self.signals = signals
self.signals.asignal.connect(self.coso1)
self.setGeometry(500,150, 600, 300)
vbox1 = QVBoxLayout()
self.buttom1 = QPushButton("Click")
self.buttom1.clicked.connect(self.signals.do_something)
vbox1.addWidget(self.buttom1)
self.setLayout(vbox1)
def coso1(self, sig):
print("self.combo.currentText()>>>>>" + sig)
