I saw that capability (widget in canvas) mentioned, just never had occasion to use it so it never got Celtk-ized. And at this point you may really have to fork Celtk to take it forward in re use of Tk widgets since I am concentrating on Cello for widgets.

But, hey, stop whining, how hard would it be to whip up a find-definitions dialog using Celtk? I once did a killer inspector using Cello. Do the classic incremental thing, just get ACL to pop up a list of definitions using as much standard mop as possible. Costanza has done some work on a portable MOP, maybe contrib to that as you go (since moppery will be needed to replicate the ACL IDE). Needless to say, a Slime-killer is something I would love to do just to piss off the Yobbos, and if I end up switching to LW for enough work it might just happen. Not yet, tho. kt kt

Thanks, Thomas. That did the trick. Frank Am 29.12.2006 um 14:16 schrieb Thomas F.

An issue arising out of > the Lisp API to Tk? Follow the bouncing API.... It's a Tk thing -- canvasses are their own weird little world where you manually place canvas-items instead of letting a layout manager place widgets. canvas-windows just bridge the gap. You could automatically make the canvas-window if you try to place a widget in a canvas, but it seems like it might just make things uglier.

[cells-devel] Celtk: Why can I place a label but not a rectangle with :parent-x and :parent-y ?
by Frank Goenninger 30 Dec '06

30 Dec '06

Hi all you Celtk users: In my quest to design a beautiful GUI for my app I try to place my widgets in the app window. Therefore I try the following (part of Celtk-based code): (defmodel app-window (window) () (:default-initargs :width (c-in 1000) :height (c-in 600) :kids (c? (the-kids (mk-rectangle :tk-fill "grey" :height 100 :width 200 :parent-y 100 :parent-x 100))))) ... which results in an error saying :PARENT-Y :PARENT-X :HEIGHT are invalid initargs to make-instance of class #<STANDARD-CLASS CTK:RECTANGLE>. The valid initargs are :DISABLEDWIDTH :ACTIVEWIDTH :WIDTH :TAGS :STATE :DISABLEDSTIPPLE :ACTIVESTIPPLE :STIPPLE :DISABLEDOUTLINESTIPPLE :ACTIVEOUTLINESTIPPLE :OUTLINESTIPPLE :DISABLEDOUTLINE :ACTIVEOUTLINE :OUTLINE :OFFSET :DISABLEDFILL :ACTIVEFILL :TK-FILL :DASHOFFSET :DISABLEDDASH :ACTIVEDASH :DASH :DECORATIONS :COORDS :COORDS-TWEAK :L-COORDS :ID-NO :USER-ERRORS :ON-KEY-UP :ON-KEY-DOWN :ON-COMMAND :TIMERS :TK-CLASS :MD-NAME :ID :VALUE :AWAKEN-ON-INIT-P :FM-PARENT. [Condition of type PROGRAM-ERROR] Hm - now, that means I can't really say I want a specific height for a rectangle?! Also, I can't place this rectangle... Trying this with a label works Ok. How can that be? Any pointers really appreciated. Frank

[cells-devel] Celtk: Button as kid of a canvas ...
by Frank Goenninger 28 Dec '06

28 Dec '06

Hi all: being too lazy for searching in the code of Celtk I wonder if there is a way to have a button as a kid of a canvas - same of for an entry widget ... I figure that the kid would be configured differently compared to being a kid of a frame... Anyone done that before? Thx for any pointers... Best wishes - Frank

ok, bring it back on list then. there are useful infos in these mails... (or not :) > We? Parallel project? You and Thomas? C4? Other_________? > > Is it open source?

What > are you using it for, if you can say? oh, i tought you heard about it, its at: http://common-lisp.net/project/computed-class/ it's rewritten from scratch. has a little different nomenclature, but i'm planning to rename "computed-state" to "cell" after talking with the others, to bring the two projects closer. of course you're welcome to contribute/use/join the list/etc... > I do not mind at all.

"the model" is an UML-like data model integrated with CLOS. you write something like UML (semantically) and get a working app with persistency and a web gui. we is a small startup, working on http://common-lisp.net/project/cl-wdim/ if you don't mind we may bring this back to the list. but i didn't want to shamelessly advertise the project on the cells list... -- - attila "- The truth is that I've been too considerate, and so became unintentionally cruel... - I understand. - No, you don't understand!

I just added variables.lisp to CVS just so folks can find it, and at the same time modified cells.lpr /not/ to show it. From there, the macro: (defmacro def-c-variable (v-name cell &key ephemeral owning unchanged-if) (declare (ignore unchanged-if)) (let ((c 'whathef)) ;;(gensym))) `(progn (eval-when (:compile-toplevel :load-toplevel) (define-symbol-macro ,v-name (c-variable-accessor ',v-name)) (setf (md-slot-cell-type 'null ',v-name) (when ,ephemeral :ephemeral)) (when ,owning (setf (md-slot-owning 'null ',v-name) t))) (eval-when (:load-toplevel) (let ((,c ,cell)) (md-install-cell nil ',v-name ,c) (awaken-cell ,c))) ',v-name))) So this: (def-c-variable *kenny* (c-in nil)) Expands to this: (progn (eval-when (:compile-toplevel :load-toplevel) (define-symbol-macro *kenny* (c-variable-accessor '*kenny*)) (setf (md-slot-cell-type 'null '*kenny*) (when nil :ephemeral)) (when nil (setf (md-slot-owning 'null '*kenny*) t))) (eval-when (:load-toplevel) (let ((whathef (c-in nil))) (md-install-cell nil '*kenny* whathef) (awaken-cell whathef))) '*kenny*) Obviously still experimental. :) ken

[cells-devel] CVS: Missing file variables.lisp ?!
by Frank Goenninger 13 Dec '06

13 Dec '06

Hi Kenny, I just updated Cells from CVS and found a file "variables.lisp" mentioned in the ACL project file ("cells.lpr"). This is not to be found in the ASDF project file cells.asd. As I think the .asd and the .lpr should be equal in meaning I think you introduced variables.lisp recently but just did not check it into CVS. Or am I wrong? Thx for info. Cheers, Frank

[cells-devel] Celtk: Error "Slot CTK::PACKING is missing from ..."
by Frank Goenninger 11 Dec '06

11 Dec '06

Hi all: Another Celtk challenge for me: The slot CTK::PACKING is missing from the object SENDREQUEST-PUBLISH-RB-GROUP of class #<STANDARD-CLASS CTK::MENU-RADIO-GROUP> during operation SLOT-VALUE [Condition of type PROGRAM-ERROR] is resulting from this piece of code: (mk-row () (mk-stack () (mk-menu-radio-group :id :sendrequest-publish-rb-group :selection (c-in nil) :kids (c? (the-kids (mk-menu-entry-radiobutton :label "Request/Reply" :value :request/reply) (mk-menu-entry-radiobutton :label "Publish" :value :publish) )))) (mk-stack () (mk-row () (mk-label :text "Timeout: " :width 10) (mk-entry :id :timeout-entry :width 6) (mk-label :text "s"))) menu-radio-group inherits from menu-entry which inherits from tk-object. I can't locate the source of this error ... Thanks for any hints! Best, Frank

[cells-devel] Celtk: strange error for mk-entry after CVS update ...

Any ideas? Thx! Frank
