QGL::AlphaChannel | 0x0008 | Enables the use of an alpha channel. |
QGL::AccumBuffer | 0x0010 | Enables the use of an accumulation buffer. |
QGL::StencilBuffer | 0x0020 | Enables the use of a stencil buffer. |
QGL::StereoBuffers | 0x0040 | Enables the use of a stereo buffers for use with visualization hardware. |
QGL::DirectRendering | 0x0080 | Specifies that the context is used for direct rendering to a display. |
QGL::HasOverlay | 0x0100 | Enables the use of an overlay. |
QGL::SampleBuffers | 0x0200 | Enables the use of sample buffers. |
QGL::SingleBuffer | DoubleBuffer<<16 | Specifies the use of a single buffer, as opposed to double buffers. |
QGL::NoDepthBuffer | DepthBuffer<<16 | Disables the use of a depth buffer. |
QGL::ColorIndex | Rgba<<16 | Specifies that the context should use a color index as its pixel format. |
QGL::NoAlphaChannel | AlphaChannel<<16 | Disables the use of an alpha channel. |
QGL::NoAccumBuffer | AccumBuffer<<16 | Disables the use of an accumulation buffer. |
QGL::NoStencilBuffer | StencilBuffer<<16 | Disables the use of a stencil buffer. |
QGL::NoStereoBuffers | StereoBuffers<<16 | Disables the use of stereo buffers. |
QGL::IndirectRendering | DirectRendering<<16 | Specifies that the context is used for indirect rendering to a buffer. |
QGL::NoOverlay | HasOverlay<<16 | Disables the use of an overlay. |
QGL::NoSampleBuffers | SampleBuffers<<16 | Disables the use of sample buffers. |
The FormatOptions type is a typedef for QFlags<FormatOption>. It stores an OR combination of FormatOption values.
