BackendRendererOpenGL3(ContextLoadFuncType contextLoadFunction)
Initializes the backend renderer. This will initialize GLAD to use (modern) OpenGL.
TGUI_NODISCARD std::shared_ptr< BackendTexture > createTexture() override
Creates a new empty texture object.
TGUI_NODISCARD unsigned int getMaximumTextureSize() override
Get the maximum allowed texture size.
BackendRendererOpenGL3(SDLContextLoadFuncType contextLoadFunction)
Helper constructor so that you can pass SDL_GL_GetProcAddress without needing to cast the type.
Base class for the backend renderer, which is responsible for creating text and texture objects.
Definition BackendRenderer.hpp:45
Namespace that contains all TGUI functions and classes.
