typedef ConstBaseIterator < EventMap > | Iterator |
Class that represents a surface that can have geometry based imagery drawn to it.
A RenderingSurface has a number of queues that can be used for rendering; normal window rendering will typically be done on RQ_BASE queue, things that are overlaid everything else are rendered to RQ_OVERLAY.
CEGUI::RenderingSurface::RenderingSurface | ( | RenderTarget & | target | ) |
Constructor for RenderingSurface objects.
target | RenderTarget object that will receive rendered output from the RenderingSurface being created. |
void CEGUI::RenderingSurface::addGeometryBuffer | ( | const RenderQueueID | queue, |
const GeometryBuffer & | buffer | ||
) |
Add the specified GeometryBuffer to the specified queue for rendering when the RenderingSurface is drawn.
queue | One of the RenderQueueID enumerated values indicating which prioritised queue the GeometryBuffer should be added to. |
buffer | GeometryBuffer object to be added to the specified rendering queue. |
void CEGUI::RenderingSurface::clearGeometry | ( | const RenderQueueID | queue | ) |
Clears all GeometryBuffers from the specified rendering queue.
queue | One of the RenderQueueID enumerated values indicating which prioritised queue is to to be cleared. |
void CEGUI::RenderingSurface::clearGeometry | ( | ) |
Clears all GeometryBuffers from all rendering queues.
|
virtual |
Create and return a reference to a child RenderingWindow object that will render back onto this RenderingSurface when it's draw member function is called.
The RenderingWindow returned is initially owned by the RenderingSurface that created it.
target | TextureTarget object that will receive rendered output from the RenderingWindow being creatd. |
|
virtual |
Destroy a RenderingWindow we own. If we are not the present owner of the given RenderingWindow, nothing happens.
window | RenderingWindow object that is to be destroyed. |
|
virtual |
Draw the GeometryBuffers for all rendering queues to the RenderTarget that this RenderingSurface is targetting.
The GeometryBuffers remain in the rendering queues after the draw operation is complete. This allows the next draw operation to occur without needing to requeue all the GeometryBuffers (if for instance the sequence of buffers to be drawn remains unchanged).
Reimplemented in CEGUI::RenderingWindow.
const RenderTarget& CEGUI::RenderingSurface::getRenderTarget | ( | ) | const |
Return the RenderTarget object that this RenderingSurface is drawing to.
|
virtual |
Marks the RenderingSurface as invalid, causing the geometry to be rerendered to the RenderTarget next time draw is called.
Note that some surface types can never be in a 'valid' state and so rerendering occurs whenever draw is called. This function mainly exists as a means to hint to other surface types - those that physically cache the rendered output - that geometry content has changed and the cached imagery should be cleared and redrawn.
Reimplemented in CEGUI::RenderingWindow.
bool CEGUI::RenderingSurface::isInvalidated | ( | ) | const |
Return whether this RenderingSurface is invalidated.
Note that some surface types can never be in a 'valid' state and so will always return true.
|
virtual |
Return whether this RenderingSurface is actually an instance of the RenderingWindow subclass.
Reimplemented in CEGUI::RenderingWindow.
void CEGUI::RenderingSurface::removeGeometryBuffer | ( | const RenderQueueID | queue, |
const GeometryBuffer & | buffer | ||
) |
Remove the specified GeometryBuffer from the specified queue.
queue | One of the RenderQueueID enumerated values indicating which prioritised queue the GeometryBuffer should be removed from. |
buffer | GeometryBuffer object to be removed from the specified rendering queue. |
|
virtual |
transfer ownership of the RenderingWindow to this RenderingSurface.
Transfer ownership of the given RenderingWindow to this RenderingSurface. The result is \e generally the same as if this RenderingSurface had created the RenderingWindow in the first place.
window | RenderingWindow object that this RenderingSurface is to take ownership of. |
|
static |
Event fired when rendering of a RenderQueue completes for the RenderingSurface. Handlers are passed a const RenderQueueEventArgs reference with RenderQueueEventArgs::queueID set to one of the RenderQueueID enumerated values indicating the queue that has completed rendering.
|
static |
Event fired when rendering of a RenderQueue begins for the RenderingSurface. Handlers are passed a const RenderQueueEventArgs reference with RenderQueueEventArgs::queueID set to one of the RenderQueueID enumerated values indicating the queue that is about to start rendering.
