[Mondrian] MORectangleShape>>mightHaveChildren
by Alexandre Bergel 09 Feb '09

09 Feb '09

Dear List, It appears that a rectangle shape in the Squeak version of Mondrian may or may not have children. Conceptually, when a rectangle cannot have children? I am trying to figure out whether this something we should keep.

Mondrian and events
by Alexandre Bergel 02 Feb '09

02 Feb '09

Dear list, I enhanced Mondrian to support announcement based event. Here an example: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= | view | view := MOViewRenderer new. view subscribe: MOMouseEnter do: [:ann | (ann element notNil and: [(ann element isKindOf: MORoot) not]) ifTrue: [MOPopup show: ann element printString] ifFalse: [MOPopup remove] ]. view subscribe: MOMouseDown do: [:ann | ann inspect]. view nodeShape: (MORectangleShape new width: 30; height: 40). view nodes: (1 to: 5). view open -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Two effects: - putting the mouse over a box display a popup window. - clicking on a box open an inspector I propose an extension. I think this respects what was done in VW. But maybe one wants to have different event handler regarding the objects inserted. For example: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= | view | view := MOViewRenderer new. view nodeShape: (MORectangleShape new width: 30; height: 40). view subscribe: MOMouseDown do: [:ann | ann inspect]. view nodes: (1 to: 5). view subscribe: MOMouseDown do: [:ann | Beeper beep]. view nodes: (5 to: 10). view open -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Nodes from 1 to 5 will open an inspector when clicked. Nodes from 1 to 10 will beep instead. Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

Mondrian and Squeak: tooltip
by Alexandre Bergel 01 Feb '09

01 Feb '09

Hi again, Tool tips are a kind of shape. I found that strange. In VW, a view answers to the message interaction, returning an event handler. I like this approach. Is there a reason why in Squeak it is so different? Cheers, Alexandre _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

Mondrian in Squeak
by Alexandre Bergel 01 Feb '09

01 Feb '09

Dear List, I've tried the following: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= | view builder | builder := MOFormsBuilder new. builder column; left; pref. builder row; left; row; left; row; left; pref. builder x: 1 y: 1 add: (MORectangleShape new). builder x: 1 y: 2 add: (MOLabelShape new). view := MOViewRenderer new. view node: #blah using: builder shape. view open -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= A shape is simply added to the builder. If you execute the following code, you will not get what you expect (a text 'blah' below a rectangle). If you manage if get the hand back (Cmd-.), then you will see that the message width is sent to an instance of MOLabelShape. This method does not exist, thus raising an exception. I have several questions: - How can a shape knows the width of the string it is supposed to display, if the shape does not know about what to display? The "what to display" is provided in the display:on: method. - In VW, the LabelShape>>width returns a widthBlock. This variable does not exist in Squeak. Is there a reason why? Is there something very different regarding labels from the Squeak and VisualWorks version? A more general question, tt seems that the strategy to compute width and height of label in VW differs in Squeak. Any reason for this? Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

Famix3 documentation
by Laval Jannik 29 Jan '09

Hi all, does a documentation exist for Famix3 ? I have found the documentation of Famix2: http://www.iam.unibe.ch/~famoos/FAMIX/Famix20/Html/famix20.html But there is no link for the Famix3. I have only found the link on the diagram of Famix3 beta 14. Tanks a lot. Jannik
