Render target implementation that makes use of modern OpenGL.
Definition: BackendRenderTargetOpenGL3.hpp:40
void setView(FloatRect view, FloatRect viewport, Vector2f targetSize) override
Informs the render target about which part of the window is used for rendering.
BackendRenderTargetOpenGL3()
Default constructor.
void updateClipping(FloatRect clipRect, FloatRect clipViewport) override
Called from addClippingLayer and removeClippingLayer to apply the clipping.
~BackendRenderTargetOpenGL3()
Destructor.
void drawGui(const std::shared_ptr< RootContainer > &root) override
Draws the gui and all of its widgets.
void drawVertexArray(const RenderStates &states, const Vertex *vertices, std::size_t vertexCount, const 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 setClearColor(const Color &color) override
Select the color that will be used by clearScreen. This will be called when gui.mainLoop() is called.
void clearScreen() override
Clears the screen, called at the beginning of each frame when gui.mainLoop() is called.
Base class for render targets.
