[mcclim-devel] Problems in reading with :timeout
by Tomi K Neste 06 May '05

06 May '05

Oops.. accidently sent this to rpgoldman only :-| Just tried on SBCL with recent McCLIM and :timeout 0 works fine >0 values still seem to be blocking forever. Looks like clim-internals:stream-input-wait keeps continuously calling clim-internals:event-queue-listen-or-wait with wrong TIMEOUT. Or maybe not, it's all (still) bit over my head The :timeout 0 => NIL still seems to a problem on CMUCL, but that's on a few months old version of McCLIM, so maybe it's fixed and irrelevant by now anyway. I really should update my CMUCL stuff on that laptop... I'm trying to figure out how to do some simple animation, like a clock or process browser that should keep on updating every few seconds. So I thought the way to go would be specializing the READ-COMMAND or READ-FRAME-COMMAND and use the :timeout where approriate. I also thought about using different thread for the pane updating, but I'm not sure if that would be a smart thing to do. So I'm wondering if there's a canonical way to accomplish something like that, some sources perhaps? BTW, big thanks to all McCLIM developers, fascinating stuff :-)

Re: [mcclim-devel] resizeable panes

Off the top of my head, something like this within your layout should world: (vertically () top-pane (make-pane 'clim-extensions:box-adjuster-gadget) bottom-pane) The idea is that you insert it a layout between the panes you want it to resize. This should work fine for a horizontal layout also, the box-adjuster-gadget takes its orientation from its parent.

[mcclim-devel] Problems in reading with :timeout
by Tomi K Neste 04 May '05

04 May '05

I'm having some newb confusion about the timeout value in stream input functions, (read-gesture ...) etc. (read-gesture :timeout 0) always just returns NIL, while timeout values >0 don't seem to have any effect at all. For example, in the Listener (read-gesture :timeout 1) keeps blocking until some gesture is given. Another source of confusion is the :input-wait-handler. From reading the spec I got the idea that it should be called "continously" when there isn't any input in the given stream, but it looks like the function is never executed. Are these real problems or am I just missing something obvious?

Hi all. I've just been trying to build scigraph with the latest cvs McCLIM and cmucl 19a, and I've been hitting a variety of problems. Has anybody else seen any trouble with recent cvs McCLIM?

[mcclim-devel] interactor-pane scrolls off the bottom
by tim＠tenkan.org 02 May '05

02 May '05

If you say (define-application-frame foo () () (:pane (make-pane 'interactor-pane :width 400 :height 300))) (clim:run-frame-top-level (clim:make-application-frame 'foo)) You get a window. Hit RET a few times in that window, and the prompt will scroll off the bottom of it, never to return. Is it meant to work that way? -- -Tim

Here is a screenshot: http://mathshield.sourceforge.net/axiomstartuppage.png I'm guessing this is well withing McCLIM's abilities, at least to build a mockup of. I believe bold text and buttons are clickable. CY P.S. - sorry if this is a dupe, I don't think my other response made it.

[mcclim-devel] Command translator question
by Duncan Rose 01 May '05

01 May '05

I'm trying to define a presentation command translator which will invoke 'describe presentation' on specific types. Unfortunately it doesn't work (or at least, works in a way that I'm not expecting so if it's working it's not doing what I want ;-) Looking at the translators defined in the Listener and in builtin-commands.lisp hasn't helped. Here's the translator: (define-presentation-to-command-translator port-select-to-command ; name (t ; from-type com-describe ; command-name - maybe com-describe-presentation? global-command-table ; command table containing command :gesture :select ; activate on :select (left-button click) ;; :tester ... :documentation "Invoke the 'describe presentation' command on the selected presentation" :pointer-documentation ((object stream) (format stream "Describe ~A" object)) :menu t ; command should appear in popped-up menus ;; :priority ... :echo nil) ; don't echo the command when it is invoked ;; arglist must be a subset (using string-equal) of: ;; (object presentation context-type frame event window x y) (object) ;; body of translator; returns a list of the arguments to the command ;; named by command-name. (list object)) In case I was providing the wrong 'from-type' I changed it to T (all types, I hope). I've written this using the Beagle back end but it doesn't work for me when run under CLX either... Any suggestions would be appreciated, I'm obviously missing something... I've attached the complete code for context in case it's helpful. -Duncan
