~BackendRenderTargetGLES2() override
Destructor.
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 drawGui(const std::shared_ptr< RootContainer > &root) override
Draws the gui and all of its widgets.
BackendRenderTargetGLES2()
Default constructor.
void clearScreen() override
Clears the screen, called at the beginning of each frame when gui.mainLoop() is called.
void setView(FloatRect view, FloatRect viewport, Vector2f targetSize) override
Informs the render target about which part of the window is used for rendering.
void updateClipping(FloatRect clipRect, FloatRect clipViewport) override
Called from addClippingLayer and removeClippingLayer to apply the clipping.
void setClearColor(const Color &color) override
Select the color that will be used by clearScreen.
Base class for render targets.
Definition BackendRenderTarget.hpp:48
Wrapper for colors.
Definition Color.hpp:72
Namespace that contains all TGUI functions and classes.
