Description

This class provides common functionalities that are extended by TGroupIconResource and TGroupCursorResource.

Resources of type RT_GROUP_ICON and RT_GROUP_CURSOR represent a .ico or .cur file, respectively. However, data isn't contained in a single resource, but it's scattered over several different resources. That is, a .ico file contains an icon, which is made of several different images (for different sizes and color depth); when it is represented as a resource, however, the RT_GROUP_ICON resource only contains information about the single images, which are contained each in a different resource of type RT_ICON. The single resources are pretty unuseful alone, since they only consist of raw image data: they must be accessed in the contest of the RT_GROUP_ICON resource, which provides information about them.

TGroupIconResource and TGroupCursorResource provide a way to handle resources of these types as if they were .ico or .cur files. This class implements common functionalities, since icons and cursors are very similar.
