I think what it comes down to is there simply is no beginner level guide written (or even tutorial that I can find) which says "here's how to create an application." Because, at root level, that's what new developers are asking - I have an interface in my head, how do build it and I get it to run? One suggestion I do have is an extension of the requests to include the file-selector as a component in McCLIM - create a library of "standard interface components" that people can quickly bolt together, and then they will have only to define the tricky, application specific parts of the code. Thinks like menu bars, file-selectors, tabbed windows, scrollable windows, status bars, slidable controllers, button palettes, example configuration dialogs, etc. would be really nice to have available as bolt on components. These would also form a very good basis for a graphical UI designer ala glade or QT Designer. For each of these, a sort of mini API can be defined, and how they are implimented internally can change without bothering user code. This is probably way beyond the CLIM spec, but it would be an excellent way to lower the barrier of entry. And as people create new components, if appropriate they can be added to the available library until it's only a special case presentation like a spreadsheet grid or a mathematical document or an image editing display/interaction that would need to be custom written - most of the rest of the graphical components could be gotten from "standard" or even previous custom objects contributed to the library. And a graphical CLIM interface builder could possibly go a long way towards helping people create "correct" code or at least avoid errors. Does this make sense to anyone else?

Re: [mcclim-devel] Axiom
by C Y 29 Apr '05

I note, to my surprise, the screenshots page on Axiom only has the TeXmacs screenshots. I'll try to get this sucker working tonight and make some of the browser. Basically, as far as I can remember, it was a text browser with the ability to imbed images and send commands to Axiom. A breakthrough for its time but rather dated now - it should be pretty simple (in theory) to mock up something like it. (Sinking feeling as this gets filed under famous last words...)

[mcclim-devel] Axiom
by C Y 28 Apr '05

28 Apr '05

There has been some discussion going on on the Axiom list about graphics, and Tim Daly made the following interesting remark: "I've looked at McClim which is a path I'd dearly love to take but so far I've not gotten it to work. If someone could reproduce the first page of the browser (a few buttons, an image) in McClim that might be enough to get me over the hurdle. A pure lisp solution is preferred." How difficult would this be to create (assume current McCLIM skills = <very small quantity>) ? I would like to take a stab at this (or if somebody with actual skill does that would be even better) because if Axiom impliments a GUI in McCLIM it would (IMHO) do a world of good for both Axiom and McCLIM. I have gotten McCLIM to work before (though not on GCL) and if it's not insanely difficult I'd like to take a shot at it. CY __________________________________________________ Do You Yahoo!?

I should mention the browser is not the most complicated thing in the world graphically, as it dates from a rather earlier period in interface history. (A few buttons, objects, etc.) I can't produce a screenshot right now because my last install went wonky :-(.

[mcclim-devel] A couple of Beagle changes
by Duncan Rose 27 Apr '05

27 Apr '05

The following patch (generated with 'cvs diff -u beagle', which I hope is correct) should modify Beagle so that the following are 'fixed' (i.e. as fixed as they ever get when I do things which is not very ;-) + rectangular tiles + line dashes + patterns (not stencils though) + dispatch repaint when mirror transform is set now untransforms the mirror region by the mirror transformation to hopefully speed things up a little (still veeery slow when the output history is large) beagle/image.lisp can be removed from Beagle, and the lisp-bezier-path.lisp file needs adding. Thanks, -Duncan

[mcclim-devel] clim-debugger
by Peter Mechlenborg 26 Apr '05

26 Apr '05

Hi all I finally took some time off to do a bit on the debugger again. It can be found here: http://www.daimi.au.dk/~metch/lisp/clim-debugger.lisp Changes: - A "more button" have been added, so more stack-frames can be viewed if 20 isn't enough. - Scroll-bars have been added, thanks to Elliott Johnson. There's still a small problem though. The scroll-bars do not remember their position when a stack-frame or "more" is pressed. I don't know how to fix this, couldn't find anything in the specs and Clouseau didn't help either. Do anyone of you know how to do this? - Frame variables are viewed with Clouseau when pressed. What do you think? Have fun, -- Peter

[mcclim-devel] Drawing graphs & scaling
by Thibault Langlois 22 Apr '05

22 Apr '05

Hello, I would like to be able to scale a graph: (defmethod plot ((object tree) stream) (with-scaling (stream 0.7) (draw-graph (list (root-node object)) #'draw-node-colors :stream stream))) where draw-graph is directly inspired from an example in allegro CLIM manual: (defun draw-graph (root-nodes draw-node-function &rest keys) (apply #'format-graph-from-roots root-nodes #'(lambda (node s) (multiple-value-bind () (with-output-as-presentation (s node 'node) (funcall draw-node-function node s)))) #'(lambda (n) (if (visible-p n) (children n))) keys)) and draw-node-colors draws a node using draw-rectangle*. The problem is that when the scaling factor is not 1 the nodes are not correctly placed (although they are correctly scaled) with respect to arcs. Any ideas ? Thanks. Thibault

[mcclim-devel] How to change color of a text field
by Paolo Amoroso 21 Apr '05

21 Apr '05

How can I change the color of the text displayed in a text field? Does the CLIM specification allow this? Paolo -- Lisp Propulsion Laboratory log - http://www.paoloamoroso.it/log
