PySide2 Spacebar press

[SGaist]

if key in [Qt.Key_0, Qt.Key_1]:
    print("smothering")

[Caeden]

@SGaist but where? I would need an event for this, seeing as the keyboardpress event doesnt trigger from it

[jsulm]

@Caeden https://doc.qt.io/qt-5/qkeyevent.html#key

[Caeden]

@jsulm When I print(dir(MainWindow)) there is no QEventKey

[jsulm]

@Caeden The event is right here: def keyPressEvent(self, event)

[Caeden]

@jsulm Yes, but the event isn't triggered when I press the spacebar.

def keyPressEvent(self, event) -> None:
        """Key press"""

        print('hi')

this does not print 'hi' when I press the spacebar. Spacebar is the key i'm after and it does not trigger this event

[jsulm]

@Caeden One moment. In which exact widget do you want to enter space? Which widget has focus when you press space? MainWindow is a container widget containing other widgets, right?

[Caeden]

@jsulm I just want it to accept a spacebar press. Here is my ui code, its automatically generated so doesnt look amazingly neat
I believe that I have one QWidget on my main window, because on linux for some reason background-color: black; makes it appear black on Qt Designer, but shows as a white background. It worked fine on windows before, but anyway, thats irrelevant because I'm just using a widget instead

@jsulm When I do

 def event(self, _event):
        print('hi, {}, {}'.format(_event, self.num))
        self.num += 1

and press spacebar it seems that when I press spacebar it counts it as <PySide2.QtCore.QEvent object at 0x7f600b1b9b40>. How do I turn this into an event function?

[jsulm]

@Caeden said in PySide2 Spacebar press:

event function?

Event is not a function it is an object.

_event.key()

should do.
