[ltk-user] LTK and ECLS
by Marko Kocić 15 Aug '08

15 Aug '08

Hi all, Has anybody been able to use some of the recent versions of ECLS with LTK? After I load ltk, when I try either (ltk:ltktest) or (ltk::ltk-eyes), only empty Tcl window is displayed. After closing it I got the following error in REPL: > (ltk::ltk-eyes) Read or write operation to stream #<output stream "\"c:/Tcl/bin/wish85.exe\" \"-name\" \"LTK\""> signaled an error. Explanation: Invalid argument. Broken at SI:BYTECODES.No restarts available. Broken at SI:BYTECODES. >> It works ok in SBCL though. Regards, Marko

[ltk-user] images
by Simon Friedberger 19 Jul '08

19 Jul '08

Hello everybody! I read in the docs that images and bitmaps can be created on canvas and that can be passed appropriate objects. Now I wonder: What are those objects? How do I e.g. put an icon I have in a file on a button? Or put a jpeg in a canvas. Something like that. A little example would be appreciated. Thanks Simon

What is the format for image-setpixel data argument? Shouldn't this be documented?

[ltk-user] PATCH a much better patch that works on 8.4 and 8.5
by Johan Ur Riise 27 Apr '08

27 Apr '08

Here I leave activate-tile on the outside of the with-ltk form in tile-test. In stead, I have deferred the renaming of widgets, using the same technique as is used with require-tile, pushing a lambda to the init hook. Works beautifully with tile-test on both tcl 8.4 and 8.5, and also with my own application. The "unless" in require-tile _could_ be a premature optimization, but it could also be a hint to the next generation programmers that this is only for an ancient wish, and could be removed. So forget my last pathc, but the one adding ttk:: is needed diff --git a/ltk-tile.lisp b/ltk-tile.lisp index 0d8c39c..7fb9914 100644 --- a/ltk-tile.lisp +++ b/ltk-tile.lisp @@ -32,15 +32,21 @@ (defparameter *tile-widgets* '(button check-button entry label radio-button scrollbar )) ;;; checkbutton combobox dialog notebook paned progressbar treeview menubutton separator +(defun tclversion () + (send-wish "senddatastrings [info tclversion]") + (read-from-string (first (ltk::read-data)))) + (defun require-tile () - (send-wish "package require tile")) + (unless (> (tclversion) 8.4) + (send-wish "package require tile"))) (defun activate-tile () (pushnew #'require-tile *init-wish-hook*) - (dolist (widget *tile-widgets*) - (let ((w (make-instance widget))) - (unless (search "ttk::" (widget-class-name w)) - (setf (widget-class-name w) (concatenate 'string "ttk::" (widget-class-name w))))))) + (pushnew (lambda () (dolist (widget *tile-widgets*) + (let ((w (make-instance widget))) + (unless (search "ttk::" (widget-class-name w)) + (setf (widget-class-name w) (concatenate 'string "ttk::" (widget-class-name w))))))) + *init-wish-hook*)) (defun theme-names () (send-wish "senddatastrings [ttk::style theme names]") -- 1.5.4.3

[ltk-user] Ltk on Vista
by christopher melen 12 Apr '08

12 Apr '08

I know there's been a problem with Ltk on WinXP, but I've just tested it on Vista and it seems to run fine. Here's my setup - Sony PCG-7Z2M Laptop Windows Vista Home Premium Clisp-Win32 ActiveTCL 8.4.18.0 I'm going to test again when I've set up Cygwin on that machine, so that I've got a decent asdf-friendly environment (just loaded ltk.lisp for that quick test). Will also test with SBCL. By the way thanks Peter on an absolutely terrific program. Best, Chris ___________________________________________________________ Yahoo!

[ltk-user] Ltk gui freezing on windows
by Jonathan Johansen 08 Apr '08

08 Apr '08

Hi All, I have recently tried to use Phil Armitage's lisp editor ABLE (of course written with Ltk). However on my windows XP desktop, it didn't work very well. It would start up, but when I pressed a key (such as Ctrl-n), it froze. It didn't take any extra resources, it just didn't respond. Anyway, to cut a long story short, I found this tcl/tk bug report: http://sourceforge.net/tracker/index.php?func=detail&aid=1779265&group_id=1… Then I (with the help of Phil) figured out a workaround (mostly through sheer luck). I put a call to ltk:do-msg before the user gets a chance to press anything, and to avoid freezing the application, you have to dismiss the message box with a press of enter (clicking OK is not OK). So like it says in the bug report above, it seems that an enter will stop it freezing. Being 'lazy', I don't want to have to customise every single tcl/tk/ltk application I want to run on this computer, so is there a way to include an extra 'enter' or #\Newline in key places in the Ltk code to avoid this happening? They could all use #+win32 because I think it only seems to happen to that type of OS :(. Anyway, now I'm going to start learning to use ABLE! Cheers, Jonathan

13 Mar '08

As mentioned in my previous mail to the list, I have been looking at using scrolled-frame. Attached, you will find a patch against ltk-0.91 (downloaded this evening to make sure). I hope that the list accepts attachments and that Yahoo webmail will not mangle it.
