enum QGL::FormatOption▲
flags QGL::FormatOptions
This enum specifies the format options that can be used to configure an OpenGL context. These are set using QGLFormat::setOption().
|
Constant |
Value |
Description |
|---|---|---|
|
QGL::DoubleBuffer |
0x0001 |
Specifies the use of double buffering. |
|
QGL::DepthBuffer |
0x0002 |
Enables the use of a depth buffer. |
|
QGL::Rgba |
0x0004 |
Specifies that the context should use RGBA as its pixel format. |
|
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::DeprecatedFunctions |
0x0400 |
Enables the use of deprecated functionality for OpenGL 3.x contexts. A context with deprecated functionality enabled is called a full context in the OpenGL specification. |
|
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. |
|
QGL::NoDeprecatedFunctions |
DeprecatedFunctions << 16 |
Disables the use of deprecated functionality for OpenGL 3.x contexts. A context with deprecated functionality disabled is called a forward compatible context in the OpenGL specification. |
The FormatOptions type is a typedef for QFlags<FormatOption>. It stores an OR combination of FormatOption values.
