Detailed Description

Qt includes.

class DtDrawerColl:

Abstract base class of drawer collections. Concrete subclasses can be chained together using the decorator pattern. This allows the user to mix various subsets of drawers. For example, basic drawers which work on all o/s + drawers for windows basic drawers + true type fonts ttf + windows

The drawer collection owns any component with which it is constructed, and will delete it upon destruction.
