Hello, As my paste on irc lisp, did not have any answer, I turning again to this more specialized mailing list. I have this MClim problem. The application runs fine on Linux with SBCL 1.0.13, xorg-x11-server 1.3.0.0-9.fc7, a recent version of MClim. But doesn't on my Mac (Darwin PowerPC) with MacOS 10.5 (leopard), SBCL 1.0.16, cvs version of MClim, Xquartz 2.1.5 - (xorg-server 1.3.0-apple22)(2.1.5). I have tried to create the smallest as possible application where the problems occurs (attached). Just compile the file and launch mini::(start) On Linux, I have the desired behaviour: a circle blinks (red/green/red/...) on the display pane and at the bottom of the window application, the "quit" button is displayed and works. On the Mac, the circle blinks correctly but the "Quit" button never shows up. For a while the application is killable with C-c C-c (under Slime), but after a while there is no way to kill it than to stop Lisp and restart everything (even /the/ <http://www.lispworks.com/reference/HyperSpec/Body/s_the.htm> X server). Note that this application used to work on Mac OS 10.3 (Panther) with older versions of everything. I suspect the X server to behave differently from before. But now I don't see how to make the application work. This is too bad, as I usually use a similar application for my Lisp undergraduate course. If anyone has an idea, it will be welcomed.

[mcclim-devel] mcclim dialogs
by Paul Bowyer 16 Jun '11

16 Jun '11

Hello mcclim developers: I'm in the throws of learning common lisp and mcclim and I've been able to piece together some working code that functions fairly well by reading from various mcclim specification documents, brief tutorials, and by looking at the various examples that come with mcclim. I have a question regarding the proper way to set up a simple dialog for entering values using mcclim. I've tried using the "accepting-values" macro directly, but I haven't been able to control the position or the size of the dialog when it appears, although I do get usable information from it. From reading the specifications, I've tried using the various position control parameters, but they seem to have no affect. I've tried defining an application frame with a pane derived from "accept-values" but I haven't been successful getting that to run. Does someone have a simple example of either, or both, of these methods of setting up a dialog with mcclim that they would be willing to share? I'm using SBCL-1.0.48 with slime, if that has any importance. Thanks, Paul

[mcclim-devel] BUG in RECORDING.LISP > DEFINE-INVOKE-WITH
by Richard and/or Dorrit 10 Jun '11

When compiling with SBCL 1.0.49, discovered the dynamic-extent declaration at the end of this has two typos, where the dynamic extent is declared for #'continuation and #'constructor, rather than for the gensym'd names for them. So the second version of this code is with this issue fixed. (defmacro define-invoke-with (macro-name func-name record-type doc-string) `(defmacro ,macro-name ((stream &optional (record-type '',record-type) (record (gensym)) &rest initargs) &body body) ,doc-string (setq stream (stream-designator-symbol stream '*standard-output*)) (with-gensyms (constructor continuation) (multiple-value-bind (bindings m-i-args) (rebind-arguments initargs) `(let ,bindings (flet ((,constructor () (make-instance ,record-type ,@m-i-args)) (,continuation (,stream ,record) ,(declare-ignorable-form* stream record) ,@body)) (declare (dynamic-extent #'constructor #'continuation)) (,',func-name ,stream #',continuation ,record-type #',constructor ,@m-i-args))))))) ;;; here's the versioned with the repaired dynamic-extent declaration: (defmacro define-invoke-with (macro-name func-name record-type doc-string) `(defmacro ,macro-name ((stream &optional (record-type '',record-type) (record (gensym)) &rest initargs) &body body) ,doc-string (setq stream (stream-designator-symbol stream '*standard-output*)) (with-gensyms (constructor continuation) (multiple-value-bind (bindings m-i-args) (rebind-arguments initargs) `(let ,bindings (flet ((,constructor () (make-instance ,record-type ,@m-i-args)) (,continuation (,stream ,record) ,(declare-ignorable-form* stream record) ,@body)) (declare (dynamic-extent #',constructor #',continuation)) (,',func-name ,stream #',continuation ,record-type #',constructor ,@m-i-args)))))))
