Member Type Documentation▲
enum QClearBuffers::BufferType▲
flags 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.
Property Documentation▲
buffers : BufferType▲
Specifies the buffer type to be used.
Access functions:
-
buffers() const
-
void setBuffers( buffers)
Notifier signal:
-
void buffersChanged( buffers)
clearColor : QColor▲
Specifies the clear color to be used.
Access functions:
-
clearColor() const
-
void setClearColor(const &color)
