void clearScreen() override
Clears the screen, called at the beginning of each frame when gui.mainLoop() is called.
BackendRenderTargetSDL(SDL_Renderer *renderer)
Default constructor.
void drawGui(const std::shared_ptr< RootContainer > &root) override
Draws the gui and all of its widgets.
void setClearColor(const Color &color) override
Select the color that will be used by clearScreen.
void drawVertexArray(const RenderStates &states, const Vertex *vertices, std::size_t vertexCount, const unsigned int *indices, std::size_t indexCount, const std::shared_ptr< BackendTexture > &texture) override
Draws a vertex array. This is called by the other draw functions.
void updateClipping(FloatRect clipRect, FloatRect clipViewport) override
Called from addClippingLayer and removeClippingLayer to apply the clipping.
void setView(FloatRect view, FloatRect viewport, Vector2f targetSize) override
Informs the render target about which part of the window is used for rendering.
Base class for render targets.
