- What I CAN do: Draw squares, hexes, grids in a window's presentation space.
- Vary the size or number of such figures when the window is resized (the
- entire presentation space is redrawn with graphics primatives when this
- happens). Create and manipulate scroll bars.
-
- What I WANT to do: Draw a fairly complex figure once in a virtual
- presentation space and use the window on the screen as a view into the
- complex figure.
-
- I think I have two questions, one how to do this in concept (presentation
- space, graphics segments, retained graphics...I don't understand them very
- well), the other what routines to call to accomplish it. The Technical
- Reference Library should answer the second one, but even having read
- _Programming Guide, Vol III_, understanding the first still eludes me. Any
- illumination would be greatly appreciated, be it in news or e-mail.

- P.S. - I am using G++-EMX and attempting to extend the API; if anyone who
- has the IBM OS/2 header files could send me the information on value sets
- or slider bars (and maybe even the index numbers for their functions? Or a
- way to figure that out without any of the *Set/2 tools), it would probably
- make my life a lot easier.
