[mcclim-devel] [bug] Asynchronous ID-CHOICE-ERROR -- CLX or McCLIM?
by Nikodemus Siivola 23 Aug '08

23 Aug '08

This may be a CLX issue, or a problem in the CLX backend -- I would not know, but the test-case is pure CLIM. After the error future attempts to RUN-FRAME-TOP-LEVEL result in similar errors. Backtrace follows, self contained test-case attached (RUN-FRAME-TOP-LEVEL, then "Stress" -- it may take a while, but eventually it breaks for me.)

[mcclim-devel] Gadget based accepting-values
by Clinton Ebadi 04 Jul '08

04 Jul '08

Greetings, Attached is a patch, accepting-values-gadgets-1, that makes accepting-values capable of working of with gadget based views. The (probably) uncontroversal part is exporting the CLIM 2.2 (from the Franz user guide) gadget views and the related constants. I added view-gadget-initargs support to gadget-view so gadgets can be created properly. The code merely stashes all the provided initargs into a slot and does no sanity checking. Should this somehow verify that the initargs are valid for the related gadget class? If so, what would be the cleanest way? I also caught the lack of a +check-box-view+ and added it. To the frame-manager protocol class I added the CLIM 2.2 frame-manager-dialog-view method which (for now) defaults to a textual rather than gadget based view. I noticed the XXX comment attached so I am unsure if this is an OK place to add it. accepting-values-stream now returns the frame manager dialog view as its stream-default-view. The Franz user guide says that this ought to be setfable; to which class should I add the slot and accessor? To accepting-values itself I moved the final cleanup of the input editor records into a generic, finally-finalize-query-record, so that accept-present-default methods that don't contain a text editing field can actually work. There are a few quick hackish methods for accepting from a text-field-view/gadget-dialog-view (the assumption being that they contain an input editing record so just calling them with +textual-dialog-view+ will work). I also reworked the accept-present-default for text-field-view to always call the textual-dialog-view method even if the width is not set. Also attached is avg.lisp which is a work in progress I'd like someone a bit more knowledgeable about CLIM to look at which implements gadget based accepting-values methods as per the Franz user guide. This is loosely based upon the public domain code found in [1]. If it looks ok I can split it up into the appropriate files in McCLIM and submit a patch. It seems to work well enough, but I am unsure if I have implemented things well. The most suspect bit is line 225 where I set the cache-test of the updating-output-record to return t always. I was having problems with a new gadget being created every time the value changed. gui.lisp contains a small test frame for testing whether the gadgets actually work.

[mcclim-devel] McClim up and running
by christopher melen 12 Jun '08

12 Jun '08

OK so I have McClim up and running on my Mac (PPC with OS X 10.4.9). I've tried it with two Lisps so far, OpenMCL (now Clozure CL) and SBCL. Some observations - 1. SBCL works best. I had some problems with the listener under OpenMCL, especially when I tried to change the path (complained that it was 'not of type LIST'). 2. I have to run it with Apple's X11 - which is not a problem for me, as I use it frequently, but I was wondering if anyone's got it running without it. I had to set the DISPLAY environment variable in my .bash_profile to 127.0.0.1:0.0. So I have to run it from the terminal or an xterm, not from Emacs Slime (my preferred set-up). 3. When an app starts (for instance, the listener, or Gsharp) it takes a while to 'come alive'. Menus aren't usable for about a minute. After that it's OK, though, and I can restart an app (in the same Lisp session) without issue. I think I've only encountered this problem with SBCL. 4. I have also tried to get McClim running on my Windows box. I can compile it for Clisp (native Cygwin version, haven't tried the Win32 port), but when I try and run the Listener or any of the demos it just hangs (even with Cygwin's X11 running). I have also tried using the Win32 port of SBCL, but for some reason CLX won't compile on that. Might give ACL a go, if I can get ASDF to work properly with it. 4. I am hoping to use McClim to build the gui for my current project. I am keen to use it because of the fact that it's Lisp all the way through, unlike other Lisp-based gui kits (Ltk, cells-gtk, lispbuilder, for example) which, while perhaps slicker, feel a bit superficial (just wrappers for Tcl/Tk, Gtk, etc.). I have been tempted to fork out for ACL or LispWorks, but then there are licensing issues when it comes to redistributing my application. So I really want to stick with McClim. Any thoughts/comments much appreciated. Thanks, Chris __________________________________________________________ Sent from Yahoo! Mail. A Smarter Email http://uk.docs.yahoo.com/nowyoucan.html

Hi, On http://common-lisp.net/project/mcclim/, under "Recent News", the recent "St. George's Day" release is shown as having occurred in 2007 rather than 2008. -- Scott

Clozure CL is also supposed to be good, so I'd be > interested in hearing the specifics of the error you got (backtrace?). With Clozure CL the only command that works in the listener's Filesystem menu is 'Up Directory'; everything else gives me this - Error: value PATHNAME is not of the expected type LIST. While executing: CCL::FRAME-SUPPLIED-ARGS, in process repl-thread. > You can set the environment variable for Emacs (M-x setenv)... I'd tried that, but it still errored, asking if I wanted to use the local unix display. > It is normal for McCLIM apps to be slightly sluggish at first, because > the CLOS caches need to be filled the first time generic functions are > called. Successive invocations of the program should start up > faster. A pause of an entire minute is highly unusual, however. Which > version of SBCL is that? When I run it with Clozure CL there's no delay at all. Only with SBCL. I'm running version 1.0.2. > How does it hang? Does it take up all available CPU time or block? > McCLIM works on CLISP on Unix, so the implementation itself should > not be a problem. Yes, CPU on the Windows machine is 100% at that point. I'll have a go on my laptop, which runs Vista, see if that's any better. Thanks, Chris __________________________________________________________ Sent from Yahoo! Mail.

[mcclim-devel] cl-jpeg dependency with ASDF-install (bug?)
by christopher melen 13 May '08

When I try to ASDF-install McClim (on Mac OS X) it complains that it can't install a dependency, cl-jpeg. This library appears to be no longer available. __________________________________________________________ Sent from Yahoo! Mail. A Smarter Email http://uk.docs.yahoo.com/nowyoucan.html

[mcclim-devel] Small patch for pixie look sliders
by Clinton Ebadi 06 May '08

06 May '08

Greetings, When testing a small program I noticed that the value-changed callbacks in pixie look sliders were not being called. I compared the handle-event methods for the concrete gadget and pixie looks, and I think the attached patch is the correct fix (and just copied from (handle-event <slider-pane> <pointer-button-release-event>)). -- Jessie: i thought your beard took the oxygen from the air and made it breathable for you
