python - How to bind a function to an Action from Qt menubar?

Question

I'm using Python3 and PyQt5, make my widgets and windows in Qt Designer. What is more, I do not generate .py files from a .ui. I simply load it using next code:

class MainWindow(QMainWindow):

def __init__(self):
    super(MainWindow, self).__init__()
    uic.loadUi('UI/Qt/source/MainWindow.ui', self)

So, I wanted to know, how do I bind menu bar actions to functions.

Is there any way I can do something like this?

self.getActionByName("actionTest_Action").connect(self.do_something)

Answer 1

It is not necessary to use findChild when using loadUi since this method adds the object to the attributes of the class using the objectName as a name, for example in this particular case a cleaner code than the other answer is:

class MainWindow(QMainWindow):
    def __init__(self):
        super(MainWindow, self).__init__()
        uic.loadUi('UI/Qt/source/MainWindow.ui', self)

        self.actionTest_Action.triggered.connect(self.test)

    def test(self):
        print("Test")
