CHnExtBmpIconHolder Class Reference

class CHnExtBmpIconHolder

This is an extended version of CHnIconHolder which holds a CGulIcon that does not own the bitmaps and CLiwBitmapBuffer objects that do.

Such class was needed because some of the bitmaps for icons are obtained from CLiwBitmapBuffer objects and there is no way to transfer ownership of that bitmaps from them. It is not possible to make copies of that bitmaps either, because some of them are not CFbsBitmaps but CAknBitmaps.
