Inheritance diagram for SoFloatElement:
This is the superclass of elements where the new element data replaces the old data, and where the data the element stores is a simple single precision floating point value.
This element is like a convenient light-weight version of the SoReplacedElement. It differs from the SoReplacedElement in that the set() and get() methods are already implemented, since it is known that subclasses will still contain just a single float value.

Destructor. |
|
This static method returns the class type. Reimplemented from SoElement. Reimplemented in SoGLLineWidthElement, SoGLPointSizeElement, SoLineWidthElement, SoPointSizeElement, and SoListenerGainElement. |
|
This static method returns the state stack index for the class. Reimplemented from SoElement. Reimplemented in SoGLLineWidthElement, SoGLPointSizeElement, SoLineWidthElement, SoPointSizeElement, and SoListenerGainElement. |
|
Initialize relevant common data for all instances, like the type system. Reimplemented from SoElement. Reimplemented in SoGLLineWidthElement, SoGLPointSizeElement, SoLineWidthElement, SoPointSizeElement, and SoListenerGainElement. |
|
This function initializes the element type in the given SoState. It is called for the first element of each enabled element type in SoState objects. Reimplemented from SoElement. Reimplemented in SoGLLineWidthElement, SoGLPointSizeElement, SoLineWidthElement, SoPointSizeElement, and SoListenerGainElement. |
|
This function returns If the application programmer's extension element has a matches() function, it should also have a copyMatchInfo() function. Implements SoElement. |
|
This function creates a copy of the element that contains enough information to enable the matches() function to work. Used to help with scenegraph traversal caching operations. Implements SoElement. |
|
This function is for printing element information, and is used mostly for debugging purposes. Reimplemented from SoElement. |
|
Static method for setting the value of an element in the given state at the given stack index. |
|
Static method for setting the value of an element in the given state at the given stackIndex. |
|
Static method to fetch the value of the element of this type from the given state at the given stack index. |
|
Set element value. Reimplemented in SoGLLineWidthElement, and SoGLPointSizeElement. |
|
The element's value. |
