Casts for events

kshegunov

Hello,
Is there a special method for downcasting QEvents to more concrete types? I was thinking something like qobject_cast and qgraphicsitem_cast? Should I simply stick to dynamic_cast instead?

Thanks!

Qt uses reinterpret_cast and static_cast made safe by checking QEvent::type so I suppose that's the way to go

Yes, this is what I do usually. The point is there are multiple event types that map to the same class, for example QMouseEvent and QHoverEvent. Meaning you have to check all possible types (i.e. a big switch) before doing the cast. But fair enough, if there isn't anything like qobject_cast, there isn't.
