Great! Posted another news item.
Just another note: Though all the posts so far have 'micah' in the corner, it is
possible for anyone in the pgui project to post a news item. I wrote a mini-howto on
it a while back if you're interested, but basically it just involves creating a file
in the /home/groups/p/pg/pgui/news directory of the Sourceforge shell server.

Well, I'm definitely interested in any code you've written, so send patches or stick
it in the CVS once you get a login.
I know the current field widget is quite limited, as it was originally intended just
to be a temporary fix until I could write something better. Unfortunately, since I
wrote it around last August it has stuck. I have this grand vision of a widget
(actually, more like a layout method) that can act as a text field, word processor,
web browser, etc. Basically a layout system similar to what LaTeX uses: Each word (a
group of one or more strings that can't be separated) is placed in a divnode, and
these divnodes are stacked horizontally to fill a line. Lines are linked together to
form paragraphs, and so on. This divtree can be placed inside a widget that supplies a
scrolling container and editing facilities, and presto, a SuperText widget!
It might be possible to get word-wrapping and multiline editing working in the current
field widget, but it feels like a bad design at the core.
I'm currently doing driver work under SMARTDATA's priority list, but in my "free time"
outside of that I could start work on the text layout engine. Or maybe I just write a
detailed description of what I have in mind so others can help on it?

Just text. That was one of the many options I recently moved into separate 'Set'
functions that once were parameters to the primitive.
PicoGUI doesn't have filled polygons yet.

For rectangles and frames?
Sounds useful. I know many of the themes could take advantage of that.

Yep, stuff like arcs and polygons definitely belong in the server.
No reason they aren't yet except lack of time.

Ah. Stupid bug... I had them in pgfx.c as "pgMoveto" and "pgLineto"
Fixed in the CVS now.
