I downloaded it last night. I am *very* impressed. It's much less =
primitive than you make it out to be. Very readable code. No doubt about =
it, I'm going to have to use inheritance.=20

I read the warning in the README before running the code. Good thing I =
did, because SVGA modes cause my machine to lock up (I hope someone can =
find Robert a "safe" SVGA test). I changed the resolution to mode 18 and =
it worked just fine - except for the colors, of course. You might want =
to set that as the default video mode.

After going your code examples, I see what Ralf was trying to get =
through my thick skull. :)

I've been unsure exactly how to approach inheritance. All the GUI =
libraries I've looked at use it extensively, and your code is an =
excellent source. Thanks for posting it! [Sound of code being pilfered]

One small nit - multiple assignments on a line are confusing, because =
they look like a C-like comparison is going on.

Bravo!


[WinMan Status]

I've been hammering away at WinMan for the last couple of evenings, =
retrofitting it with a new graphic engine. It's 98% done - I just need =
to take care of some mouse droppings, and junk left on the screen after =
the menus are erased. Visually, there's nothing new to see. Internally, =
it's a whole new ballgame, with support for all the graphic modes, =
color, better font handling and the like. The graphic kernel is based on =
BitBlt, so it's much more rational. Like Irv's code, though, =
optimizations should be added later, for you folks with 386s.


[Win32Lib Status]

Sorry, all - I've been spending all my time on WinMan. If there is a bug =
that's hanging you up, drop me a note and I'll try to take care of it =
ASAP. I'm going to be sticking to WinMan for a while.


[Minor Complaint for Rob]

Here's a nit about the Euphoria error message:

   Subscript value <n> is out of bounds, reading from a length-<n> =
sequence.

always confuses me, because it initially looks like there is a negative =
length to the sequence. I *think* that there are other similar messages =
that also use a leading hypen before numbers.

Thanks!

I changed the video mode to 18, and it worked just fine. Modes > 19 =
cause my machine freeze up, so thanks for the warning - but could you =
default it to mode 18?
