Detailed Description

The QSurface class is an abstraction of renderable surfaces in Qt.

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.

ConstantValueDescription
QSurface::Window0The surface is an instance of QWindow.

enum QSurface::SurfaceType

The SurfaceType enum describes what type of surface this is.

ConstantValueDescription
QSurface::RasterSurface0The surface is is composed of pixels and can be rendered to using a software rasterizer like Qt's raster paint engine.
QSurface::OpenGLSurface1The surface is an OpenGL compatible surface and can be used in conjunction with QOpenGLContext.
