## Enumeration Type Documentation

anonymous enum

Constants for use with wxGLCanvas.

Note
  Not all implementations support options such as stereo, auxiliary buffers, alpha channel, and accumulator buffer, use wxGLCanvas::IsDisplaySupported() to check for individual 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 | Specifies the number of bits for buffer if not WX_GL_RGBA.
WX_GL_LEVEL | Must be followed by 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 | Specifies number of auxiliary buffers.
WX_GL_MIN_RED | Use red buffer with most bits (> MIN_RED bits)
WX_GL_MIN_GREEN | Use green buffer with most bits (> MIN_GREEN bits)
WX_GL_MIN_BLUE | Use blue buffer with most bits (> MIN_BLUE bits)
WX_GL_MIN_ALPHA | Use alpha buffer with most bits (> MIN_ALPHA bits)
WX_GL_DEPTH_SIZE | Specifies number of bits for Z-buffer (typically 0, 16 or 32).
WX_GL_STENCIL_SIZE | Specifies number of bits for stencil buffer.
WX_GL_MIN_ACCUM_RED | Specifies minimal number of red accumulator bits.
WX_GL_MIN_ACCUM_GREEN | Specifies minimal number of green accumulator bits.
WX_GL_MIN_ACCUM_BLUE | Specifies minimal number of blue accumulator bits.
WX_GL_MIN_ACCUM_ALPHA | Specifies minimal number of alpha accumulator bits.
WX_GL_SAMPLE_BUFFERS | 1 for multisampling support (antialiasing)
WX_GL_SAMPLES | 4 for 2x2 antialiasing supersampling on most graphics cards

WX_GL_CORE_PROFILE

Request an OpenGL core profile.

Notice that using this attribute will result in also requesting OpenGL at least version 3.0.

See WX_GL_MAJOR_VERSION and WX_GL_MINOR_VERSION for more precise version selection.

Since
  3.0.3

WX_GL_MAJOR_VERSION

Request specific OpenGL core major version number (>= 3).

This attribute should be followed by the major version number requested.

It has no effect under OS X 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

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
