◆ LoadCanvasFromStream()

virtual CanvasAssetHandle * UiSystemToolsInterface::LoadCanvasFromStream ( AZ::IO::GenericStream &  stream,
const AZ::ObjectStream::FilterDescriptor &  filterDesc 
)
pure virtual

Load a canvas but do not init or activate the entities The CanvasAssetHandle is an opaque pointer only valid to be passed to the methods below.

◆ ReplaceCanvasEntity()

virtual void UiSystemToolsInterface::ReplaceCanvasEntity ( CanvasAssetHandle *  canvas,
AZ::Entity *  newCanvasEntity 
)
pure virtual

Replace the canvas entity with a new one. The old canvas entity is not deleted. The client is responsible for that.

◆ ReplaceRootSliceSliceComponent()

virtual void UiSystemToolsInterface::ReplaceRootSliceSliceComponent ( CanvasAssetHandle *  canvas,
AZ::SliceComponent *  newSliceComponent 
)
pure virtual

Replace the slice component with a new one. The old slice component is not deleted. The client is responsible for that.
