Detailed Description

Provided to generate an appearance object with better readability and understandability.

A window has an appearance. This appearance can be specified when a window is being created. To determine the appearance of a window there is a structure named nana::appearance with a bool member for each feature with can be included or excluded in the "appearance" of the windows form. But in practical development is hard to describe the style of the appearance using the struct nana::appearance. If a form would to be defined without min/max button and sizable border, then

nana::form form(x, y, width, height, nana::appearance(false, false, false, true, false));

This piece of code may be confusing because of the 5 parameters of the constructor of nana::form. So the library provides a helper class for making it easy. For better readability and understandability Nana provides three templates classes to generate an appearance object: nana::appear::decorate, nana::appear::bald and nana::appear::optional. Each provide an operator that return a corresponding nana::appearance with predefined values.
