Detailed Description

Base class for state attributes.

Member Typedef Documentation

GLMode is the value used in glEnable/glDisable(mode)

typedef unsigned int osg::StateAttribute::GLModeValue

GLModeValue is used to specify whether a mode is enabled (ON) or disabled (OFF).

GLMoveValue is also used to specify the override behavior of modes from parent to children. See enum Value description for more details.

typedef unsigned int osg::StateAttribute::OverrideValue

Override is used to specify the override behavior of StateAttributes from parent to children.

See enum Value description for more details.

A vector of osg::StateSet pointers which is used to store the parent(s) of this StateAttribute.

typedef std::pair<Type,unsigned int> osg::StateAttribute::TypeMemberPair

Simple pairing between an attribute type and the member within that attribute type group.

Member Enumeration Documentation

Type identifier to differentiate between different state types.

Values of StateAttribute::Type used to aid identification of different StateAttribute subclasses. Each subclass defines its own value in the virtual Type getType() method. When extending the osg's StateAttribute's simply define your own Type value which is unique, using the StateAttribute::Type enum as a guide of what values to use. If your new subclass needs to override a standard StateAttribute then simply use that type's value.

list values which can be used to set either GLModeValues or OverrideValues.

When using in conjunction with GLModeValues, all Values have meaning. When using in conjunction with StateAttribute OverrideValue only OFF,OVERRIDE and INHERIT are meaningful. However, they are useful when using GLModeValue and OverrideValue in conjunction with each other as when using StateSet::setAttributeAndModes(..).

Enumerator
OFF 

means that associated GLMode and Override is disabled.

ON 

means that associated GLMode is enabled and Override is disabled.

OVERRIDE 

Overriding of GLMode's or StateAttributes is enabled, so that state below it is overridden.

PROTECTED 

Protecting of GLMode's or StateAttributes is enabled, so that state from above cannot override this and below state.

INHERIT 

means that GLMode or StateAttribute should be inherited from above.
