The last version of Mondrian should be in a usable state very soon. PERT diagram can be trivially modeled in Mondrian. What I can suggest, is to download the last version of Mondrian. Have a look at the class MOReadme. It contains few examples. Do not hesitate to get in touch with me privately for help. Cheers, Alexandre On 23 Feb 2009, at 22:26, David Röthlisberger wrote:

Hi Cédrick,

...

As I need to draw a PERT diagram, I decided to give Mondrian a try.

I had a version (ported by Lukas [1]) used in OB which I started to use and read doc (code doc :) ). And I saw that Alexandre (Bergel) is working on improving another version [2].

So, which one to use (knowing that I use OB) ? I think there are differences...

I will port the visualizations used in OB to the latest version Alex is working on, as soon as he finished his work. Thus in the long run, OB will use Alex' version of Mondrian which is (imo) still loosely based on the version Lukas originally ported from VW.

So I suggest you to use the latest version of Mondrian on Squeaksource for new projects. Alex can tell you more about its status.

David

I've loaded the mondrian form squeaksource and I'm trying it. I find it quite different for the one used in OB.

Yes, but very close to the VW version. We have a number of scripts and visualization made in VW that we would like to reuse. Moreover, in my opinion, the new version is simpler to use (and probably faster to render). The incantation to install the latest version of Mondrian in Pharo: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= ScriptLoader new installer ss project: 'Mondrian'; install: 'MondrianLoader'. ScriptLoader perform: #loadMondrian -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

I'll continue to try it as I'm reading Micheal Master thesis. I'm trying on a simple graph first with tasks and node, but also I'd like a special kinf of shape. Alex, I didn't found the way to compose shape. Is it possible already ?

Yes, you can compose them using MOFormsBuilder. There are numerous example in MOReadme, MONewFormsBuilderTest, and MOFormsBuilderTest (but some of them go red). An example that you can run with: MOReadme new flagExample -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= | builder view | builder := MOFormsBuilder new. "Assuming you want a grid made up of 3 columns and 2 rows" builder column; fill; column; fill; center; column; fill. builder row; fill; row; fill; row; fill; "For the German flag" row; center; "The EU text" row; pref. "For the French flag" "We draw a German flag" builder x: 1 y: 1 w: 3 add: (MORectangleShape new width: 30; height: 7; fillColor: Color black). builder x: 1 y: 2 w: 3 add: (MORectangleShape new width: 30; height: 7; fillColor: Color red). builder x: 1 y: 3 w: 3 add: (MORectangleShape new width: 30; height: 7; fillColor: Color yellow). builder x: 1 y: 4 w: 3 add: (MOLabelShape new text: [:aNumber |'EU ', aNumber printString]). "We draw a French flag" builder x: 1 y: 5 add: (MORectangleShape new width: 10; height: 20; fillColor: Color blue). builder x: 2 y: 5 add: (MORectangleShape new width: 10; height: 20; fillColor: Color white). builder x: 3 y: 5 add: (MORectangleShape new width: 10; height: 20; fillColor: Color red). view := MOViewRenderer new. view popupText: [:aNumber | 'my value is ', aNumber printString ]. view draggable. "Let's make nodes draggable, yeah!" view nodeShape: (builder shape). view nodes: (1 to: 27). view edges: (1 to: 27) from: #yourself to: [:each | each * each]. view layout: (MOCircleLayout new). view open -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

I also wonder if we could imagine a SVGRenderer to use in conjunction with seaside :) ? What do you think ?

Yeah, that would be nice!

ps: David, concerning the graph button bar in OB, I'll suggest showing it only in the comment view.

It depends... I seldom press the comment button, except if there is a comment in it, which is rare. Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.
