Detailed Description

IlvPalette builder.

Library: xviews or winviews or mviews (mutually exclusive)

This class simplifies the process of building a new IlvPalette, starting from an existing palette, and limiting the parameters that need to be changed to just what the application needs .

Starting with a palette, the palette builder lets you change one or several palette settings, so one does not have to provide the entire set of palette parameters should only a few of them be changed.

If you need to create a new palette that is the exact copy of another one, but where, for example, the background and foreground colors are swapped and where the line width is changed, you can use the following code:

that is much more readable, less error-prone and shorter than the equivalent code:

A handy use case is when you want to create a set of IlvPalette objects that are based on a reference one:

Without the Builder, you would have to repeat a large number of parameters when invoking IlvDisplay::getPalette().
