## Detailed Description

A descriptor, used when creating a context along with its window.

See RenderContextManager::createRenderContext() for more information.

## Constructor & Destructor Documentation

## ◆ RenderContextDescriptor() [1/5]

nkGraphics::RenderContextDescriptor::RenderContextDescriptor | ( |  | ) |
| noexcept

Default constructor.

## ◆ RenderContextDescriptor() [2/5]

nkGraphics::RenderContextDescriptor::RenderContextDescriptor | ( | nkWinUi::Window * | window,
|  | bool | vsync = `false`
| ) |  |
| noexcept

On window constructor.

Parameters

  window | The window the context described should render to.
  vsync | Whether the context described should use vsync (true) or not (false).

Remarks
  The context will be considered as rendering on screen, and size will be derived from the window given.

## ◆ RenderContextDescriptor() [3/5]

nkGraphics::RenderContextDescriptor::RenderContextDescriptor | ( | Texture * | colorTarget | ) |
| noexcept

On texture constructor. The texture will be used as the color target.

Parameters

  colorTarget | The texture the context described should render to.

Remarks
  The context will be considered as rendering off screen, and size will be derived from the texture given.

## ◆ RenderContextDescriptor() [4/5]

nkGraphics::RenderContextDescriptor::RenderContextDescriptor | ( | Texture * | colorTarget,
|  | Texture * | depthTarget
| ) |  |
| noexcept

On textures constructor.

Parameters

  colorTarget | The texture the context described should render to.
  depthTarget | The texture the context described should use as a depth buffer.

Remarks
  The context will be considered as rendering off screen, and size will be derived from the color target given.

## ◆ RenderContextDescriptor() [5/5]

nkGraphics::RenderContextDescriptor::RenderContextDescriptor | ( | unsigned int | width,
|  | unsigned int | height,
|  | bool | forOffscreen,
|  | bool | vsync = `false`
| ) |  |
| noexcept

Automatic constructor.

Parameters

  width | The width of the context described, in pixels.
  height | The height of the context described, in pixels.
  forOffscreen | Whether the context described should be off-screen (true) or not (false).
  vsync | Whether the context described should use vsync (true) or not (false). This can only work when rendering to a window.

Remarks
  For on-screen contexts, a window will be created, while off-screen contexts will create a texture. In both cases, the associated depth will also be created.

## Member Function Documentation

## ◆ getWidth()

unsigned int nkGraphics::RenderContextDescriptor::getWidth | ( |  | ) | const

Returns
  The width set into the descriptor.

Remarks
  The value returned won't be derived from a potential window or texture. Rather, it will be directly mapped to the value provided to the automatic constructor.

## ◆ getHeight()

unsigned int nkGraphics::RenderContextDescriptor::getHeight | ( |  | ) | const

Returns
  The height set into the descriptor.

Remarks
  The value returned won't be derived from a potential window or texture. Rather, it will be directly mapped to the value provided to the automatic constructor.

## ◆ getWindow()

nkWinUi::Window* nkGraphics::RenderContextDescriptor::getWindow | ( |  | ) | const

Returns
  The window set into the descriptor.

## ◆ getColorTarget()

Texture* nkGraphics::RenderContextDescriptor::getColorTarget | ( |  | ) | const

Returns
  The color target set into the descriptor.

## ◆ getDepthTarget()

Texture* nkGraphics::RenderContextDescriptor::getDepthTarget | ( |  | ) | const

Returns
  The depth target set into the descriptor.

## ◆ getOffscreenContext()

bool nkGraphics::RenderContextDescriptor::getOffscreenContext | ( |  | ) | const

Returns
  Whether the descriptor has been set as offscreen (true) or not (false).

Remarks
  The value returned won't be derived from a potential window or texture. Rather, it will be directly mapped to the value provided to the automatic constructor.

## ◆ getVsync()

bool nkGraphics::RenderContextDescriptor::getVsync | ( |  | ) | const

Returns
  Whether the descriptor has been set to use vertical sync (true) or not (false).

Remarks
  The value returned won't be derived from a potential window or texture. Rather, it will be directly mapped to the value provided to the automatic or window constructor.
