Detailed Description

A thread-safe subclass of RenderEventHandler.

Allows to receive RenderEvents from a differnet thread then the render thread. The producer thread calls the PutEvent() method to push new events into the event handler, these events will be stored in a

Inherits CoreGraphics::RenderEventHandler.

◆ HandleEvent()

bool CoreGraphics::ThreadSafeRenderEventHandler::HandleEvent ( const RenderEvent & e )

protectedvirtual

called when an event should be processed, override this method in your subclass

Handle an event.

This method is called in the consumer thread context from the HandlePendingEvents() method for each pending event. Override this method in your subclass to process the event.

Reimplemented from CoreGraphics::RenderEventHandler.

◆ HandlePendingEvents()

void CoreGraphics::ThreadSafeRenderEventHandler::HandlePendingEvents ( )

handle all pending events (called by consumer thread)

Process pending events.

This method should be called frequently by the consumer thread. Pending events will be deqeued from the internel event queue and the HandleEvent() method will be called once per event.

◆ PutEvent()

bool CoreGraphics::ThreadSafeRenderEventHandler::PutEvent ( const RenderEvent & e )

virtual

called by RenderDevice when an event happens

Put an event into the event handler.

This method is called by the render thread's RenderDevice. Events are queued until the consumer thread processes them by calling HandlePendingEvents().

Reimplemented from CoreGraphics::RenderEventHandler.
