[ltk-user] Bold font for label
by syll-dev＠laposte.net 17 Jan '12

17 Jan '12

Hello I can't set the "bold" style to a label's font : (with-ltk () (make-instance 'label :text "..." :font '(:weight :bold) :pack '(:side :left))) (I've a similar error with 3 instead of :bold for example) -> "Tcl/Tk error: expected integer but got "BOLD)" How does it work ?

[ltk-user] tk-princ changed
by Daniel Herring 14 Nov '11

14 Nov '11

I bumped into problems with SVN revision 261. It added tkescaping to tk-princ, where there previously was none. This change broke part of treeview-heading. A patch to make treeview-heading work with the new tk-princ is attached. example: (tk-princ "{stuff}") old result: "{stuff}" new result: "\{stuff\}" new code for old result: (tk-princ '("stuff")) The docstring for tk-princ says "Like princ (format ~a), but convert a lisp list to a Tk list." but the code is now very different. Should the docstring change to match the new code, or should the code be reverted to match the docstring? Thanks, Daniel

[ltk-user] nothing happens at ltktest
by claudio romanini 01 Oct '11

01 Oct '11

hello to all I'd like to study LTK, but I got stuck at the very start I run "(load "e:/lisp/ltk/ltk-0.96/ltk")" ok, "(in-package :ltk)" ok, and then "(ltktest)": after a slight pause Emacs prints 0 and returns the prompt; no errors, then, but the problem is that nothing else happens! same thing if i run "(ltk::ltk-eyes)" I checked paths, etc (or so I think), and don't know what to do; in particular, I tried to modify ltk.lisp as follows: (defvar *wish-pathname* ; #+freebsd "wish8.4" ; #-freebsd "wish" "wish.exe") (defvar *debug-tk* t) my configuration: Windows Vista, ActiveState tcl/tk 8.5, the LispBox suite (CCL, Emacs, Slime), ltk-0.96 thanks in advance Claudio ____________________________________________________________ FREE 3D EARTH SCREENSAVER - Watch the Earth right on your desktop!

[ltk-user] problems with create-text
by Andre RsFiveTwo 13 Sep '11

13 Sep '11

Hi, I'm trying to create an animation with words based on the (ltktest) function in the library (rotate). For that I'm storing the words in a plist. The code to maintain the words is: (defvar *initial-word-energy* 100) (defvar *words* '()) ; list of words in the form (:text :x :y :energy) (defun make-word (text x y display-item) (list :text text :x x :y y :display-item display-item :energy *initial-word-energy*)) (defun add-word (word) (push word *words*)) Then I created a button that will add words to the plist and to the canvas: (enter-text-button (make-instance 'button :master controls :text "Enter text" :command (lambda () ;;store word in *words* (let* ((text (text user-text-entry)) (x (random (read-from-string (cget drawing-canvas-reference :width)))) (y (random (read-from-string (cget drawing-canvas-reference :height)))) ;;put text in canvas (display-item (create-text drawing-canvas-reference x y text)) (word (make-word text x y display-item))) ;;store new word (add-word word) ;;clear entry widget (setf (text user-text-entry) "") (focus user-text-entry) (finish-output))))) The idea is that a word will store the position, the text, other things and the visual representation of the text. In the animation part (same code as rotate in the library) I move the words, and here is the problem. If I try the move changing the coordinates of the updated values of x and y of the word the text apearing in the canvas 'jumps' in the first move, afterward it move normally. The other alternative is to use itemmove, which works. but I would like to just manipulate x and y of the word and transpose it to the created text item in the canvas. ;;move display item [do not work] ---> (set-coords *drawing-canvas-reference* (getf word :display-item) (list (getf word :x) (getf word :y))) [works] ----> (itemmove *drawing-canvas-reference* (getf word :display-item) atract-x atract-y) So, I would like to understand better why there seems to be a difference in the values of x an y for the element stored and the element displayed, although they have been created with the same values. If possible, I would like to know how can I query the created text element about it's x and y values. Sorry for the long message. Any help is appreciated. Thanks, André

[ltk-user] [IDEA] Update ltk to Tk 8.5.
by Krzysztof Drewniak 13 Sep '11

13 Sep '11

Tk 8.5 adds lots of new widgets, and the ttk extension which allows "themed" widgets for a native look-and-feel. I think it would be a good idea to update ltk for the new framework. I am willing to help write the code once the weekend rolls around. Thanks, Krzysztof Drewniak -- X-Real-Email-With-Antispam: krzysdrewniak at gmail dot com pgp key on keyserver.ubuntu.com 2388E924

[ltk-user] how to read properties of widgets
by Andre RsFiveTwo 02 Sep '11

02 Sep '11

Hi, I'm starting to use the ltk library to build a twitter client and I'm liking it a lot. I'm having trouble trying to read the properties of widgets. I know for to set them, using configure, but I can't read them back. More specifically, I'm trying to read the width and height of a canvas. Any help would be appreciated. Thanks, André

[ltk-user] configuring widgets
by norman hochstetler 18 Aug '11

18 Aug '11

Hi Again, Still delighted with Ltk but having problem getting general widgets configured for background color, font, etc. Certain ones seem to work fine, others complain configuration pairs not workable. Could you send me an example script which will (for instance) provide background color and font for a scrollable listbox ? Would much appreciate. Thanks in advance. Norm Hochstetler
