void | RenderingSurface::transferRenderingWindow (RenderingWindow &) |
RenderingWindow is a RenderingSurface that can be "drawn back" onto another RenderingSurface and is primarily intended to be used as a kind of cache for rendered imagery.
CEGUI::RenderingWindow::RenderingWindow | ( | TextureTarget & | target, |
RenderingSurface & | owner | ||
) |
Constructor for RenderingWindow objects.
target | The TextureTarget based object that will be used as the target for content rendering done by the RenderingWindow. |
owner | The RenderingSurface object that will be our initial owner. This RenderingSurface is also the target where our cached imagery will be rendered back to. |
void CEGUI::RenderingWindow::draw | ( | ) | [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 from CEGUI::RenderingSurface.
const RenderingSurface& CEGUI::RenderingWindow::getOwner | ( | ) | const |
Return the RenderingSurface that owns the RenderingWindow. This is also the RenderingSurface that will be used when the RenderingWindow renders back it's cached imagery content.
const Vector3f& CEGUI::RenderingWindow::getPivot | ( | ) | const |
Return the rotation pivot point location for the RenderingWindow.
const Vector2f& CEGUI::RenderingWindow::getPosition | ( | ) | const |
Return the current pixel position of the RenderingWindow. The origin is at the top-left corner.
Return a pointer to the RenderEffect currently being used with the RenderingWindow. A return value of 0 indicates that no RenderEffect is being used.
const Quaternion& CEGUI::RenderingWindow::getRotation | ( | ) | const |
Return the current rotation being applied to the RenderingWindow.
const Sizef& CEGUI::RenderingWindow::getSize | ( | ) | const |
Return the current size of the RenderingWindow in pixels.
const TextureTarget& CEGUI::RenderingWindow::getTextureTarget | ( | ) | const |
Return the TextureTarget object that is the target for content rendered to this RenderingWindows. This is the same object passed into the constructor.
void CEGUI::RenderingWindow::invalidate | ( | ) | [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 from CEGUI::RenderingSurface.
Mark the geometry used when rendering the RenderingWindow back to it's owning RenderingSurface as invalid so that it gets regenerated on the next rendering pass.
This is separate from the main invalidate() function because in most cases invalidating the cached imagery will not require the potentially expensive regeneration of the geometry for the RenderingWindow itself.
bool CEGUI::RenderingWindow::isRenderingWindow | ( | ) | const [virtual] |
Return whether this RenderingSurface is actually an instance of the RenderingWindow subclass.
Reimplemented from CEGUI::RenderingSurface.
generate geometry to be used when rendering back the RenderingWindow to it's owning RenderingSurface.
void CEGUI::RenderingWindow::setClippingRegion | ( | const Rectf & | region | ) |
Set the clipping region that will be used when rendering the imagery for this RenderingWindow back onto the RenderingSurface that owns it.
region | Rect object describing a rectangular clipping region. |
void CEGUI::RenderingWindow::setPivot | ( | const Vector3f & | pivot | ) |
Set the location of the pivot point around which the RenderingWindow will be rotated.
pivot | Vector3 describing the three dimensional point around which the RenderingWindow will be rotated. |
void CEGUI::RenderingWindow::setPosition | ( | const Vector2f & | position | ) |
Set the two dimensional position of the RenderingWindow in pixels. The origin is at the top-left corner.
position | Vector2 object describing the desired location of the RenderingWindow, in pixels. |
void CEGUI::RenderingWindow::setRenderEffect | ( | RenderEffect * | effect | ) |
Set the RenderEffect that should be used with the RenderingWindow. This may be 0 to remove a previously set RenderEffect.
void CEGUI::RenderingWindow::setRotation | ( | const Quaternion & | rotation | ) |
Set the rotation quaternion to be used when rendering the RenderingWindow back onto it's owning RenderingSurface.
rotation | Quaternion object describing the rotation. |
void CEGUI::RenderingWindow::setSize | ( | const Sizef & | size | ) |
Set the size of the RenderingWindow in pixels.
size | Size object that describes the desired size of the RenderingWindow, in pixels. |
void CEGUI::RenderingWindow::update | ( | const float | elapsed | ) |
Peform time based updated for the RenderingWindow.
elapsed | float value describing the number of seconds that have passed since the previous call to update. |
