[PyQt] Application not hiding from taskbar

I figured out how to solve my little conundrum. My solution is so ugly
I'm ashamed but I can't figure out why self.hide() doesn't hide my
window in the first place. Here's the final code:

    def hideEvent(self, event):
        if ph.is_windows():
            self.hidden = True
    def showEvent(self, event):
        if ph.is_windows() and self.hidden:
            self.hidden = False

Kind regards,
