\section{\class{wxColour}}\label{wxcolour}
|
|
|
|
A colour is an object representing a combination of Red, Green, and Blue (RGB) intensity values,
|
|
and is used to determine drawing colours. See the
|
|
entry for \helpref{wxColourDatabase}{wxcolourdatabase} for how a pointer to a predefined,
|
|
named colour may be returned instead of creating a new colour.
|
|
|
|
Valid RGB values are in the range 0 to 255.

\section{\class{wxColourDatabase}}\label{wxcolourdatabase}
|
|
|

|
set of named colours (such as ``BLACK'', ``LIGHT GREY''). The
|
|
application may add to this set if desired by using {\it Append}. There
|
|
is only one instance of this class: {\bf wxTheColourDatabase}.
