Enumerators | |
---|---|
ForwardCompatible |
Forward compatible context. |
Debug |
Debug context. Enabled automatically if supported by the driver and the Flag:: |
RobustAccess |
Context with robust access. |
ResetIsolation |
Context with reset isolation. |
NoError new in Git master |
Context without error reporting. Might result in better performance, but situations that would have generated errors instead cause undefined behavior. Enabled automatically if supported by the driver and the Flag:: |
QuietLog new in Git master |
Print only warnings and errors instead of the usual startup log listing used extensions and workarounds. Ignored if Flag:: Corresponds to the |
VerboseLog new in Git master |
Print additional information on startup in addition to the usual startup log that lists used extensions and workarounds. Has a precedence over Flag:: Corresponds to the |
GpuValidation new in Git master |
Enable GPU validation, if available. Has a precedence over Flag:: Corresponds to the |

Function documentation
GLConfiguration& Magnum:: Platform:: Sdl2Application:: GLConfiguration:: setFlags(Flags flags)
Set context flags.
Returns | Reference to self (for method chaining) |
---|
Default is Flag::
GLConfiguration& Magnum:: Platform:: Sdl2Application:: GLConfiguration:: addFlags(Flags flags)
Add context flags.
Returns | Reference to self (for method chaining) |
---|
Unlike setFlags(), ORs the flags with existing instead of replacing them. Useful for preserving the defaults.
GLConfiguration& Magnum:: Platform:: Sdl2Application:: GLConfiguration:: clearFlags(Flags flags)
Clear context flags.
Returns | Reference to self (for method chaining) |
---|
Unlike setFlags(), ANDs the inverse of flags
with existing instead of replacing them. Useful for removing default flags.
GL:: Version Magnum:: Platform:: Sdl2Application:: GLConfiguration:: version() const
Context version.
GLConfiguration& Magnum:: Platform:: Sdl2Application:: GLConfiguration:: setVersion(GL:: Version version)
Set context version.
If requesting version greater or equal to OpenGL 3.1, core profile is used. The created context will then have any version which is backwards-compatible with requested one. Default is GL::
GLConfiguration& Magnum:: Platform:: Sdl2Application:: GLConfiguration:: setColorBufferSize(const Vector4i& size)
Set color buffer size.
Default is {8, 8, 8, 8}
(8-bit-per-channel RGBA).
GLConfiguration& Magnum:: Platform:: Sdl2Application:: GLConfiguration:: setDepthBufferSize(Int size)
Set depth buffer size.
Default is 24
bits.
GLConfiguration& Magnum:: Platform:: Sdl2Application:: GLConfiguration:: setStencilBufferSize(Int size)
Set stencil buffer size.
Default is 0
bits (i.e., no stencil buffer).
GLConfiguration& Magnum:: Platform:: Sdl2Application:: GLConfiguration:: setSampleCount(Int count)
Set sample count.
Returns | Reference to self (for method chaining) |
---|
Default is 0
, thus no multisampling. See also GL::
bool Magnum:: Platform:: Sdl2Application:: GLConfiguration:: isSrgbCapable() const
sRGB-capable default framebuffer
GLConfiguration& Magnum:: Platform:: Sdl2Application:: GLConfiguration:: setSrgbCapable(bool enabled)
Set sRGB-capable default framebuffer.
Returns | Reference to self (for method chaining) |
---|
Default is false
. See also GL::
