## Enumeration Type Documentation

## ◆ anonymous enum

anonymous enum

Constants for use with wxGLCanvas. Most of the constants must be followed by a value. This is indicated by "(F)". Instead of these flags, the use of wxGLAttributes and wxGLContextAttrs is preferred since wxWidgets 3.1.0.

Note
  Not all implementations support options such as stereo, auxiliary buffers, alpha channel, and accumulator buffer, use wxGLCanvas::IsDisplaySupported() to check for individual visual attributes support.

Enumerator
WX_GL_RGBA | Use true color (the default if no attributes at all are specified); do not use a palette.
WX_GL_BUFFER_SIZE | (F) Specifies the number of bits for colour buffer.
WX_GL_LEVEL | (F) 0 for main buffer, >0 for overlay, <0 for underlay.
WX_GL_DOUBLEBUFFER | Use double buffering if present ("on" if no attributes specified).
WX_GL_STEREO | Use stereoscopic display.
WX_GL_AUX_BUFFERS | (F) The number of auxiliary buffers.
WX_GL_MIN_RED | (F) Use red buffer with most bits (> MIN_RED bits)
WX_GL_MIN_GREEN | (F) Use green buffer with most bits (> MIN_GREEN bits)
WX_GL_MIN_BLUE | (F) Use blue buffer with most bits (> MIN_BLUE bits)
WX_GL_MIN_ALPHA | (F) Use alpha buffer with most bits (> MIN_ALPHA bits)
WX_GL_DEPTH_SIZE | (F) Specifies number of bits for Z-buffer (typically 0, 16 or 32).
WX_GL_STENCIL_SIZE | (F) Specifies number of bits for stencil buffer.
WX_GL_MIN_ACCUM_RED | (F) Specifies minimal number of red accumulator bits.
WX_GL_MIN_ACCUM_GREEN | (F) Specifies minimal number of green accumulator bits.
WX_GL_MIN_ACCUM_BLUE | (F) Specifies minimal number of blue accumulator bits.
WX_GL_MIN_ACCUM_ALPHA | (F) Specifies minimal number of alpha accumulator bits.
WX_GL_SAMPLE_BUFFERS | (F) 1 for multi-sampling support (antialiasing)
WX_GL_SAMPLES | (F) 4 for 2x2 antialiasing supersampling on most graphics cards
WX_GL_FRAMEBUFFER_SRGB | Used to request a frame buffer sRGB capable. Since 3.1.0
WX_GL_MAJOR_VERSION | (F) Request specific OpenGL core major version number (>= 3). This attribute should be followed by the major version number requested. It has no effect under macOS where specifying WX_GL_CORE_PROFILE will result in using OpenGL version at least 3.2 but can still be used there for portability. Since 3.0.3
WX_GL_MINOR_VERSION | (F) Request specific OpenGL core minor version number. This attribute has the same semantics as WX_GL_MAJOR_VERSION but is for the minor OpenGL version, e.g. 2 if OpenGL 3.2 is requested. Since 3.0.3
WX_GL_CORE_PROFILE | Request an OpenGL core profile for the context. If the requested OpenGL version is less than 3.2, this attribute is ignored and the functionality of the context is determined solely by the requested version. Since 3.0.3
wx_GL_COMPAT_PROFILE | Request a type of context with all OpenGL features from version 1.0 to the newest available by the GPU driver. In this mode the GPU may be some slower than it would be without this compatibility attribute. Since 3.1.0
WX_GL_FORWARD_COMPAT | Request a forward-compatible context. Forward-compatible contexts are defined only for OpenGL versions 3.0 and later. They must not support functionality marked as deprecated by that version of the OpenGL API. Since 3.1.0
WX_GL_ES2 | Request an ES or ES2 ("Embedded Subsystem") context. These are special subsets of OpenGL, lacking some features of the full specification. Used mainly in embedded devices such as mobile phones. Since 3.1.0
WX_GL_DEBUG | Request debugging functionality. This tells OpenGL to prepare a set where some logs are enabled and also allows OGL to send debug messages through a callback function. Since 3.1.0
WX_GL_ROBUST_ACCESS | Request robustness, or how OpenGL handles out-of-bounds buffer object accesses and graphics reset notification behaviours. Since 3.1.0
WX_GL_NO_RESET_NOTIFY | With robustness enabled, never deliver notification of reset events. Since 3.1.0
WX_GL_LOSE_ON_RESET | With robustness enabled, if graphics reset happens, all context state is lost. Since 3.1.0
WX_GL_RESET_ISOLATION | Request OpenGL to protect other apps or shared contexts from reset side-effects. Since 3.1.0
WX_GL_RELEASE_FLUSH | Request OpenGL to flush pending commands when the context is released. Since 3.1.0
WX_GL_RELEASE_NONE | Request OpenGL to avoid flushing pending commands when the context is released. Since 3.1.0
