Wait for a trigger

I'm writing a PyQt application which needs to get some input before loading the main window. I have set up the following class (minimized):

class MyInput(QWidget):
    def __init__(self):
        super(MyInput, self).__init__()
        self.thing = False

        mybutton = QPushButton('Press me', self)
        mybutton.clicked.connect(self.set_data)

    def set_data(self):
        self.hide()
        self.destroyLater()
        self.thing = True

    def get_thing(self):
        self.show()
        return self.thing

Later, I have this function:

def ask_thing():
    mi = MyInput()
    return mi.get_thing()

Now, when I call ask_thing(), I want mi.get_thing() to wait for the button to be pressed before returning the value (or return False if it is closed). However, self.show() seems to run separately and lets the code continue executing, hitting the return statement and leaving the function.

How can I wait for input?

Maybe you have to consider changing from QWidget to QDialog. Then change the function show to exec_, which will execute the widget waiting user's interaction.
