Manages the rendering contexts available in the component.
The manager is responsible for the memory it allocates. External code should not delete it.
nkGraphics::RenderContextManager::~RenderContextManager | ( | ) |
Destructor.
const std::unordered_map<void*, RenderContext*>& nkGraphics::RenderContextManager::getRenderContextMap | ( | ) | const |
RenderContext* nkGraphics::RenderContextManager::getRenderContextOf | ( | nkWinUi::GraphicsWindow * | win | ) | const |
Retrieves the context associated to a window.
win | The window which context is needed. |
RenderContext* nkGraphics::RenderContextManager::getActiveRenderContext | ( | ) | const |
RenderContext* nkGraphics::RenderContextManager::getDefaultRenderContext | ( | ) | const |
RenderContext* nkGraphics::RenderContextManager::createRenderContext | ( | const RenderContextDescriptor & | contextDesc | ) |
Creates a render context. Depending on the description, the context will be rendering to a window, or a texture. Based on the description, the window / texture will be created on-the-fly or taken from user specified pointers.
contextDesc | The description of the context to create. |
RenderContext* nkGraphics::RenderContextManager::createRenderContextAndWindowFromConfig | ( | ) |
Creates a render context and its window, from the configuration currently set. See ConfigManager.
void nkGraphics::RenderContextManager::activateContextOf | ( | nkWinUi::GraphicsWindow * | win | ) |
Activates a context and prepares the rendering pipeline for all its defined parameters.
win | The window from which the context should be activated. |
void nkGraphics::RenderContextManager::activateContext | ( | RenderContext * | context | ) |
Activates a context and prepares the rendering pipeline for all its defined parameters.
context | The context to activate. |
void nkGraphics::RenderContextManager::eraseFor | ( | nkWinUi::GraphicsWindow * | win | ) |
Erases and frees the memory of a context.
win | The window from which the context should be deleted. |
void nkGraphics::RenderContextManager::erase | ( | RenderContext * | context | ) |
Erases and frees the memory of a context.
context | The context to free. |
