Detailed Description

FBColorAndAlpha class.

Color and alpha vector.

This class creates a list like object, which can be modified using the list protocol method. But unlike lists, its length is fixed: it always contain 4 floating point values. Thus it does not support the any list methods that would affect its length. The values within can be changed, usually via the bracket operator.

    # Supported list protocol methods:
    color = FBColorAndAlpha()
    len(color)
    print color[0]
        color[0] = 1.0

Warning:

Slicing is not supported by this object.
