Creating inherited objects from TGraphic

2004-06-12 11:39:10 AM
Is there any good online materials to assist in the process of developing a
new object from TGraphic. My objective is to build a new Bitmap object. I
though about inheriting the TBitmap object and that seems to be easier but
the internal implementation is not known to me and I need to build my own
that I can understand.
Words of wisdom would be greatly appreciated.
