QSurface Class▲

  • Header: QSurface

  • CMake:

    find_package(Qt6 REQUIRED COMPONENTS Gui)

    target_link_libraries(mytarget PRIVATE Qt6::Gui)

  • qmake: QT += gui

  • Inherited By: QOffscreenSurface and QWindow

Detailed Description▲

The size of the surface is accessible with the size() function. The rendering specific attributes of the surface are accessible through the format() function.

Member Type Documentation▲

 

enum QSurface::SurfaceClass▲

The SurfaceClass enum describes the actual subclass of the surface.

Constant

Value

Description

QSurface::Window

0

The surface is an instance of QWindow.

QSurface::Offscreen

1

The surface is an instance of QOffscreenSurface.

enum QSurface::SurfaceType▲

The SurfaceType enum describes what type of surface this is.

Constant

Value

Description

QSurface::RasterSurface

0

The surface is composed of pixels and can be rendered to using a software rasterizer like Qt's raster paint engine.

QSurface::OpenGLSurface

1

The surface is an OpenGL compatible surface and can be used in conjunction with QOpenGLContext.

QSurface::RasterGLSurface

2

The surface can be rendered to using a software rasterizer, and also supports OpenGL. This surface type is intended for internal Qt use, and requires the use of private API.

QSurface::OpenVGSurface

3

The surface is an OpenVG compatible surface and can be used in conjunction with OpenVG contexts.

QSurface::VulkanSurface

4

The surface is a Vulkan compatible surface and can be used in conjunction with the Vulkan graphics API.

QSurface::MetalSurface

5

The surface is a Metal compatible surface and can be used in conjunction with Apple's Metal graphics API. This surface type is only supported on macOS and iOS.

QSurface::Direct3DSurface

6

The surface is a Direct 3D 11 and 12 compatible surface and can be used in conjunction with the DXGI and Direct3D APIs. This surface type is only supported on Windows.

Member Function Documentation▲

 

[explicit protected] QSurface::QSurface(QSurface::SurfaceClass type)▲

Creates a surface with the given type.

[virtual] QSurface::~QSurface()▲

Destroys the surface.

[pure virtual] QSurfaceFormat QSurface::format() const▲

Returns the format of the surface.

[pure virtual] QSize QSurface::size() const▲

Returns the size of the surface in pixels.

bool QSurface::supportsOpenGL() const▲

Returns true if the surface is OpenGL compatible and can be used in conjunction with QOpenGLContext; otherwise returns false.

QSurface::SurfaceClass QSurface::surfaceClass() const▲

Returns the surface class of this surface.

[pure virtual] QPlatformSurface *QSurface::surfaceHandle() const▲

Returns a handle to the platform-specific implementation of the surface.

[pure virtual] QSurface::SurfaceType QSurface::surfaceType() const▲

Returns the type of the surface.
