Detailed Description

Event propagating image/canvas size changes upwards in the network. Image inports and outports within a processor must be in the same group for the event to be propagated.

As soon as the network adds or removes a connection, all the image sinks (processors that consume images) are responsible for pushing a new resize event to the network to make sure that all the image ports in the network above it have an up-to-date view on which image sizes to use. (

shouldPropagateTo()

bool inviwo::ResizeEvent::shouldPropagateTo ( Inport *  inport, Processor *  processor, Outport *  source  )

overridevirtual

Determine if the event should be propagated upwards to inport. Can be overloaded to limit the number or ports a event is propagated through.

Reimplemented from inviwo::Event.
