Implementation of CEGUI::Renderer interface using DirectFB.

Member Function Documentation

GeometryBuffer& CEGUI::DirectFBRenderer::createGeometryBuffer ( )

virtual

Create a new GeometryBuffer and return a reference to it. You should remove the GeometryBuffer from any RenderQueues and call destroyGeometryBuffer when you want to destroy the GeometryBuffer.

Returns: GeometryBuffer object.

Implements CEGUI::Renderer.

Texture& CEGUI::DirectFBRenderer::createTexture ( )

virtual

Create a 'null' Texture object.

Returns: A newly created Texture object. The returned Texture object has no size or imagery associated with it.

Implements CEGUI::Renderer.

Texture& CEGUI::DirectFBRenderer::createTexture	(	const String &	filename,
		const String &	resourceGroup
	)

virtual

Create a Texture object using the given image file.

Parameters

filename	String object that specifies the path and filename of the image file to use when creating the texture.
resourceGroup	String objet that specifies the resource group identifier to be passed to the resource provider when loading the texture file filename.

Returns: A newly created Texture object. The initial content of the texture memory is the requested image file.

Note: Due to possible limitations of the underlying hardware, API or engine, the final size of the texture may not match the size of the loaded file. You can check the ultimate sizes by querying the Texture object after creation.

Implements CEGUI::Renderer.

Texture& CEGUI::DirectFBRenderer::createTexture ( const Size & size )

virtual

Create a Texture object with the given pixel dimensions as specified by size.

Parameters

size	Size object that describes the desired texture size.

Returns: A newly created Texture object. The initial contents of the texture memory is undefined.

Note: Due to possible limitations of the underlying hardware, API or engine, the final size of the texture may not match the requested size. You can check the ultimate sizes by querying the Texture object after creation.

Implements CEGUI::Renderer.

TextureTarget* CEGUI::DirectFBRenderer::createTextureTarget ( )

virtual

Create a TextureTarget that can be used to cache imagery; this is a RenderTarget that does not lose it's content from one frame to another.

If the renderer is unable to offer such a thing, 0 should be returned.

Returns: Pointer to a TextureTarget object that is suitable for caching imagery, or 0 if the renderer is unable to offer such a thing.

Implements CEGUI::Renderer.

void CEGUI::DirectFBRenderer::destroyGeometryBuffer ( const GeometryBuffer & buffer )

virtual

Destroy a GeometryBuffer that was returned when calling the createGeometryBuffer function. Before destroying any GeometryBuffer you should ensure that it has been removed from any RenderQueue that was using it.

Parameters

buffer The GeometryBuffer object to be destroyed.

Implements CEGUI::Renderer.

void CEGUI::DirectFBRenderer::destroyTexture ( Texture & texture )

virtual

Destroy a Texture object that was previously created by calling the createTexture functions.

Parameters

texture Texture object to be destroyed.

Implements CEGUI::Renderer.

void CEGUI::DirectFBRenderer::destroyTextureTarget ( TextureTarget * target )

virtual

Function that cleans up TextureTarget objects created with the createTextureTarget function.

Parameters

target A pointer to a TextureTarget object that was previously returned from a call to createTextureTarget.

Implements CEGUI::Renderer.

RenderingRoot& CEGUI::DirectFBRenderer::getDefaultRenderingRoot ( )

virtual

Return the default rendering root for the renderer. The default rendering root is typically a RenderingRoot that targets the entire screen (or rendering window).

Returns: RenderingRoot object that is the default RenderingSurface provided by the Renderer.

Implements CEGUI::Renderer.

const Vector2& CEGUI::DirectFBRenderer::getDisplayDPI ( ) const

virtual

Return the resolution of the display or host window in dots per inch.

Returns: Vector2 object that describes the resolution of the display or host window in DPI.

Implements CEGUI::Renderer.

const Size& CEGUI::DirectFBRenderer::getDisplaySize ( ) const

virtual

Return the size of the display or host window in pixels.

Returns: Size object describing the pixel dimesntions of the current display or host window.

Implements CEGUI::Renderer.

const String& CEGUI::DirectFBRenderer::getIdentifierString ( ) const

virtual

Return identification string for the renderer module.

Returns: String object holding text that identifies the Renderer in use.

Implements CEGUI::Renderer.

uint CEGUI::DirectFBRenderer::getMaxTextureSize ( ) const

virtual

Return the pixel size of the maximum supported texture.

Returns: Size of the maximum supported texture in pixels.

Implements CEGUI::Renderer.

void CEGUI::DirectFBRenderer::setDisplaySize ( const Size & size )

virtual

Set the size of the display or host window in pixels for this Renderer object.

This is intended to be called by the System as part of the notification
process when display size changes are notified to it via the
System::notifyDisplaySizeChanged function.

Note: The Renderer implementation should not use this function other than to perform internal state updates on the Renderer and related objects.

Parameters

size	Size object describing the dimesions of the current or host window in pixels.

Implements CEGUI::Renderer.
