newLISP Graphics & Sound / Does TK have a pulldown widget?
October 21, 2002, 12:28:39 AM
I have searched the Welch TK book after a widget "pulldownlist" (in autolisp called "popup_list") which is in windows a popular interface element (example: IE URL-adress field without typing, only picking). Does TK support this?



When not I would have a problem to port interfaces to newlisp TK.



Thats another wish for the demo-files section. Such a demo should show every supported widget with a small example how to do it. There a user could look for the typ of widget he is searching, and if it is supported to see how.



PS: I have problem to reach the follwing sites:

Whither newLISP? / infix reader macro from clisp to newLisp?
October 19, 2002, 02:07:17 AM
In the common lisp world there is a reader makro to evaluate mathematical expressions in clisp:



http://www-2.cs.cmu.edu/afs/cs/project/ai-repository/ai/lang/lisp/code/syntax/infix/0.html">http://www-2.cs.cmu.edu/afs/cs/project/ ... fix/0.html">http://www-2.cs.cmu.edu/afs/cs/project/ai-repository/ai/lang/lisp/code/syntax/infix/0.html



Would it be possible to port this to newLisp?



Why did I asked? Because in my real worlds project in the alisp world I use a autodesk runtime extension called "geomcalc.arx" to evaluate such expressions from a oracle database. When I want to port it to the outside world of acad, it has to be replaced with something other. The best I found until now, was the infix-reader macro.
