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

[cells-devel] Cells , Cello, Celtk: No more in CVS on common-lisp.net ?
by Frank Goenninger 10 Dec '06

10 Dec '06

Hi Kenny, all, I just logged into common-lisp.net. Now I wonder where the CVS repositories of said modules have gone to? Or, to put it in other words, how can I access the respective repositories? (I had to reinstall my hard disk and unfortunately lost my CVS client's parameters ...) TIA for info. Regards, Frank

[cells-devel] big day
by Ken Tilton 04 Nov '06

04 Nov '06

Big day. The pivotal md-value slot is rechristened value, and oh waht a relief it is. Turns out CL does not have it reserved. Who knew? Also big: I just took the trouble to carve out a Celtk3D.lpr (make your own damn ASD!) that does not include the widgets, including esp. the canvas widget and all its items. Just astonishing how huge those are. Loads must faster than Celtk. The idea is that Cello, as it was and is now conceived, makes all its own widgets. I thought for a while that I would mix Tk widgets with Cello widgets inside the Togl, but as soon as I started doing that I noticed that that kinda doubled the effort, and that Cello widgets look vastly better than OS native widgets. (And I happen to think native look-and-feel is not so relevant any more and certainly not for the apps I have in mind.) kt

[cells-devel] Anyone remember how we fixed keystrokes not getting picked up in Tk text fields?
by Ken Tilton 18 Oct '06

18 Oct '06

Not sure if the problem got served here -- just checked the archives and do not see anything -- but in the past year I went back and forth with someone for a few days before we finally got text fields in the ltktest-ci demo to reliably notice keystrokes. I notice that ltktest-ci does not now reliably capture keystrokes. Possibly because the fix was an adjustment to the *event-loop-delay* (var name?). I actually do not remember the fix either. Can anyone remind me? Thx, kt

[cells-devel] Interesting changes to Cells
by Ken Tilton 17 Oct '06

17 Oct '06

No, it ain't Cells4. One is a bug fix to ruled-then-input cells: "ensure current" used to be satisfied by a cell being flagged as input. Of course a ruled-then-input will not be valid initially, so the test is now that something is c-validp as well as inputp. The more exciting change (no, i did not run the Cells regression test, but my hairy application seems to work) is one I have seen coming for a while: Supose have something like: (make-kid 'ct-button :enabled (c? (some #'non-empty (kids (fm-other :thing))))) This button is part of a fixed application GUI and it keeps an eye on the kids of :thing. Now thing happens to be a component inside a little workspace, and other user controls allow them to switch the target being worked on in the workspace. A change to the target pretty much rebuilds the entire contents of the little workspace pane, including making a new widget with the name :thing. Well, this used to work without skulduggery because fm-other used to record dependencies everywhere it went in searching for :thing. Maybe that is something I should reinstate (I just realized). Anyway, the fix I came up with today seems Deeply Sensible, so let's see how it pans out: If :thing itself goes away (going back to the above example) at some point c-quiesce will disconnect the kids cell as a dependency of the button enabled cell. The fix is to flag any caller (dependent, such as enabled) as ":uncurrent", a new state between :unevaluated and :valid. I don't like dirty words or variable names, cll notwithstanding. And dirty is vague where uncurrent says what it means and means what it says. What we are saying is that a dependency on cell X of instance Y implies a dependency on the existence of Y. That just seems like a very safe thing to say, so let's see if this works as well as a kazillion kids dependency that would arise from a dependent modelspace search. kt

[cells-devel] Celtk: Added new cell slot to class window: decoration
by Frank Goenninger 28 Sep '06

28 Sep '06

Hi all: I just committed to CVS a small addition to the window class: Decoration. Setting this slot to :none creates a window without a title bar and without any borders. Useful to create Splash screens or to create windows for tooltips ... Enjoy! Regards Frank
