[mcclim-devel] Newbie problems with "accepting-values" / no method for CLIM:STREAM-CURSOR-POSITION

[Peter Braroe]

Hello!

Well what I was trying to do was to run the example as I didn't trust my
own code!  So from SLIME i (as described in the documentation) invoked:

(clim-demo::accepting-interval)

The same thing didn't work when trying directly when loading CMUCL from
the command line... The above code is same as in the 0.9.1 distro. 

Perhpas this has something to do with the multiprocessing? Forgive my
naivete but I am a newbie to LISP. I tried to do
(mp::startup-idle-and-top-level-loops) but that doesnt seem to work
(just says "no value") with SLIME so i have googled and instead set the
elisp variable slime-multiprocessing to t. I don't know if this is the
same or how to chech which processes are active - is there some kind of
"top" for LISP? Any pointers to good documentation here? I have found
clim-ug.pdf and expect to do some serious weekend reading.

Are you guys using slime? what I basically want to do as a first step is
to create a command called "tree-draw" which draws a tree diagram of my
data from the slime command line. 

What is the best way to create a window so I can do some simple stuff
like (clim:draw-line* *my-sheet* 200 10 10 150) to make my tree diagram.
I wan't the tree drawing to use data created by running previous
commands from the slime command line. 

Later I want to create a full app with a root window and child windows
for different graphs, status info, configuration dialogs and other
things. Any ideas on where I can find sources for a more full bodied app
to look at and lean from? 

Thanks for your help so far!

PS CLIM seems cool, a lot more elegant than programming in Java for
instance. But it seems a bit hard to get into due to lack of newbie
style documentation - I am happy to write together the feedback and
collection of "non-obvious but simple" stuff that an beginner needs to
know for publication somewhere suitable! Good idea?








What works for me:
gadget-test
calculator
