Three pushButtons in a shape of one

[hkvm]

There's no reason why three separate buttons would look weird. Simply put them in layouts with layoutSpacing set to 0 and there won't be a space between them.

If you're still not happy with how this looks, you'd have to subclass QPushButton and reimplement the paintEvent and do all the drawing yourself, but without a lot of work it would probably look even more weird than this.
