MOHorizontalDominanceOrderLayout

Hi Doru, You recently worked on MOHorizontalDominanceOrderLayout. This break #testCoverageLayout. Just try: view nodes: (1 to: 100). view edges: (1 to: 100) from: #yourself to: [:x | x + 1]. view layout: (MOHorizontalDominanceOrderLayout new) Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

Hello, I would like to know what are the tools provided by SmallDude? I know there is the 'side by side duplication' view, is there other visualizations ? What kind of metrics are available ?

Quadtree in Mondrian
by Alexandre Bergel 14 Aug '10

14 Aug '10

Hi! Thanks to Simon, there is a MOQuadTree class and its tests in Mondrian. Quadtree is a tree data structure that is used to partition a two dimensional space by recursively subdividing it into four quadrants or regions. We could imagine plenty of new caches using quad trees. I haven't seen any complain about speed anymore. However, I feel you restraint _yourself_ from pushing Mondrian to its limits :-) If you experience any slowdown, please keep a description of what you have done before changing your visualization. QuadTree are probably the way to go if we want to reach 1,000,000 nodes :-) Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

no overrides
by Tudor Girba 13 Aug '10

13 Aug '10

Hi, Please try to avoid overrides in your packages. It makes integration impossible. Overrides can be useful when you do not have access to the base code. But, in the case of Moose you do have access. Please, raise the point and discuss about it if you are unsure of the change. You will be surprised how often it is actually easy to change the base code, or it is easy to find another solution. Do not use overrides just because it's comfortable because in the slightly longer run they harm more than they help. Cheers, Doru -- www.tudorgirba.com "What we can governs what we wish."

Grease and Mondrian
by Alexandre Bergel 12 Aug '10

12 Aug '10

Hi! Currently, Mondrian works only on Pharo (I do not have much interest in seeing it in Squeak, even though I am not against). Should Mondrian use Grease? I have the feeling that we should not over-engineer Mondrian based on an assumption that is not verifiable currently (that Mondrian will be ported to a different Smalltalk). I will remove from Mondrian all reference of Grease. Cheers, Alexandre [*] http://blog.fitzell.ca/2010/01/easing-compatibility-with-grease.html -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

Error handling in mondrian
by Alexandre Bergel 11 Aug '10

11 Aug '10

Hi! The new version of Mondrian should make some of us happy. Before displaying the view, using the #open method, the view is rendered in a non displayed form. This means that if there is an error in your script, you will have a debugger instead of a freeze of the image. This is something I should have done at least 1 year ago. But at least, now this is done. If you have a scenario that freezes the image, please let me know. This is really annoying. Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

children shape
by Tudor Girba 10 Aug '10

10 Aug '10

Hi Alex, I would need your help in introducing the ChildrenShape. Without this, the FormsBuilder is highly underutilized. The problem I have is that currently the drawing of the nested graphs is handled on the Figure side, while it should be handled by the Shape. So, I would need your help to move this behavior while still preserving the caching logic. The ChildrenShape should then override the display:on: to display these elements. Would you have time to look into this? For example, the following code should define a umlClassShape: | builder childrenShape titleShape umlClassShape | childrenShape := MOChildrenShape new. titleShape := MORectangleShape new text: 'Title'; fillColor: Color transparent. builder := MOFormsBuilder new. builder column; center; fill; pref; grow. builder row; center; pref; fill; grow; row; center; fill; pref; grow. builder x: 1 y: 1 add: titleShape. builder x: 1 y: 2 add: childrenShape. umlClassShape := builder asShape. view nodeShape: umlClassShape. view nodes: (1 to: 3) forEach: [:each | view nodes: (1 to: 10) ] Cheers, Doru -- www.tudorgirba.com "Not knowing how to do something is not an argument for how it cannot be done."
