FBColorAndAlpha class.
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

) |
Constructor.
Explicitely construct a vector by specifying its RGBA values. Should the Alpha value not be relevant, just set it to 1.0.
Constructor.
A vector can be built from any python object with supports the tuple interface and is of a lenght of 4.

Returns the ith component Corresponds to python: print color[1].
pIndex | Index of the components to get (0:Red, 1:Green, 2:Blue) |
Sets the ith components Corresponds to python: color[1] = 0.5.
pIndex | Index of the components to set (0:Red, 1:Green, 2:Blue) |
pComponentValue | Value of component to set |
