Enum documentation

enum class Magnum::Platform::AbstractXApplication::GLConfiguration::Flag: UnsignedLong

Context flag.

Includes also everything from GL::Context::Configuration::Flag except for Flag::Windowless, which is not meant to be enabled for windowed apps.

QuietLog new in Git master

Print only warnings and errors instead of the usual startup log listing used extensions and workarounds. Ignored if Flag::VerboseLog is set.

Corresponds to the --magnum-log quiet command-line option.

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::QuietLog.

Corresponds to the --magnum-log verbose command-line option.

GpuValidation new in Git master

Enable GPU validation, if available. Has a precedence over Flag::GpuValidationNoError.

Corresponds to the --magnum-gpu-validation on command-line option.

GpuValidationNoError new in Git master

Enable a context without error reporting, if available. Ignored if Flag::GpuValidation is set.

Corresponds to the --magnum-gpu-validation no-error command-line option.

Typedef documentation

typedef Containers::EnumSet<Flag> Magnum::Platform::AbstractXApplication::GLConfiguration::Flags

Context flags.

Function documentation

GLConfiguration& Magnum::Platform::AbstractXApplication::GLConfiguration::setFlags(Flags flags)

Set context flags.

Returns Reference to self (for method chaining)

Default is no flag. To avoid clearing default flags by accident, prefer to use addFlags() and clearFlags() instead.

GLConfiguration& Magnum::Platform::AbstractXApplication::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::AbstractXApplication::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::AbstractXApplication::GLConfiguration::version() const

Context version.

GLConfiguration& Magnum::Platform::AbstractXApplication::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::Version::None, i.e. any provided version is used.
