Hey everyone,
Recently I had to use the FViewport::ViewportResizedEvent delegate. It is declared in the following way:
/** delegate type for viewport resize events ( Params: FViewport* Viewport, uint32 ) */
DECLARE_MULTICAST_DELEGATE_TwoParams(FOnViewportResized, FViewport*, uint32);
/** Send when a viewport is resized */
ENGINE_API static FOnViewportResized ViewportResizedEvent;
The question here is: what is the magical uint32 variable and what should it be called. The only instance where the event is being broadcast is from the UnrealClient.cpp - FViewport::UpdateViewportRHI
if ( !bDestroyed )
{
// send a notification that the viewport has been resized
ViewportResizedEvent.Broadcast(this, 0);
}
So what is the uint32 argument?
Not a huge issue just curiosity.
Thank you!
