Member Type Documentation

enum QClearBuffers::BufferTypeflags QClearBuffers::BufferTypeFlags

This enum type describes types of buffer to be cleared.

Constant	Value	Description
Qt3DRender::QClearBuffers::None	0	No buffers will be cleared
Qt3DRender::QClearBuffers::ColorBuffer	(1 << 0)	Clear color buffers
Qt3DRender::QClearBuffers::DepthBuffer	(1 << 1)	Clear depth buffer
Qt3DRender::QClearBuffers::StencilBuffer	(1 << 2)	Clear stencil buffer
Qt3DRender::QClearBuffers::DepthStencilBuffer	DepthBuffer | StencilBuffer	Clear depth and stencil buffers
Qt3DRender::QClearBuffers::ColorDepthBuffer	ColorBuffer | DepthBuffer	Clear color and depth buffers
Qt3DRender::QClearBuffers::ColorDepthStencilBuffer	ColorBuffer | DepthStencilBuffer	Clear color, depth and stencil buffers
Qt3DRender::QClearBuffers::AllBuffers	0xFFFFFFFF	Clear all buffers

The BufferTypeFlags type is a typedef for QFlags<BufferType>. It stores an OR combination of BufferType values.
