GetFontShaderResource()

virtual FSlateShaderResource * FSlateShaderResourceManager::GetFontShaderResource ( int32  InTextureAtlasIndex, FSlateShaderResource *  FontTextureAtlas, const class UObject *  FontMaterial  )

inlinevirtual

Reimplemented in FSlateRHIResourceManager.

GetResourceHandle() [1/2]

FSlateResourceHandle FSlateShaderResourceManager::GetResourceHandle ( const FSlateBrush &  Brush )

virtual

Reimplemented in FSlateNullShaderResourceManager.

GetResourceHandle() [2/2]

FSlateResourceHandle FSlateShaderResourceManager::GetResourceHandle ( const FSlateBrush &  Brush, FVector2f  LocalSize, float  DrawScale  )

virtual

Creates a handle to a Slate resource A handle is used as fast path for looking up a rendering resource for a given brush when adding Slate draw elements This can be cached and stored safely in code. It will become invalid when a resource is destroyed It is expensive to create a resource so do not do it in time sensitive areas

Parameters

Brush	The brush to get a rendering resource handle
LocalSize	The unscaled size of the draw element using this brush. This size is used to rescale vector graphics only
DrawScale	The scale of the draw element using this brush. This scale is used to rescale vector graphics only

Returns

The created resource handle.

GetResourcePath()

FString FSlateShaderResourceManager::GetResourcePath ( const FSlateBrush &  InBrush ) const

inlineprotected

GetShaderResource()

virtual FSlateShaderResourceProxy * FSlateShaderResourceManager::GetShaderResource ( const FSlateBrush &  Brush, FVector2f  LocalSize, float  DrawScale  )

pure virtual

Returns a texture associated with the passed in name. Should return nullptr if not found

Implemented in FSlateNullShaderResourceManager, and FSlateRHIResourceManager.

GetTextureAtlasProvider()

virtual ISlateAtlasProvider * FSlateShaderResourceManager::GetTextureAtlasProvider ( )

pure virtual

Returns the way to access the texture atlas information from this resource manager

Implemented in FSlateNullShaderResourceManager, and FSlateRHIResourceManager.
