Roassal - view shape rectangle - view shape line - returned class
by Ben Coman 06 Aug '12

06 Aug '12

In experimenting to understand ROMondrianExample>>attachPointOn: I broke into the execution as follows: "forEach: [:cls | self haltOnce." now if I highlight and inspect 'view shape line' I get a ROLine. but if I highlight and inspect 'view shape rectangle' I get a ROMondrianViewBuilder rather than the expected something like ROBox. This seems wrong that these are not consistent. cheers, -ben

Roassal - idea for compound shapes
by Ben Coman 06 Aug '12

06 Aug '12

I think the following would be the start of a good example of how Roassal works... | view rawView el1 el2 edge line | rawView := ROView new. el1 := ROElement new. el1 extent: 50@50. el1 + ROBox red + ROCircle yellow + ROLabel @ RODraggable. rawView add: el1. rawView open ...except that it would be nice if the ROLabel could be centred. In addition, being able to place the ROLabel in various "offset" locations, I think that would satisfy a lot of my composition requirements - for example building a transformer compound symbol with two overlapping circles and two labels for "equipment tag" and "power size". To that effect it would be great if ROLabel or similar could have a callback mechanism to get different attributes from the model. Alternatively I guess I could make a new subclass of ROShape that draws such that directly. cheers -ben

migrating to Roassal - custom shapes
by Ben Coman 05 Aug '12

05 Aug '12

Referring to the attached graph, what is the best way to approach the following in Roassal. Currently with Mondrian I produce a produce a custom shape using the forms builder in #mondrianShape, which is a method of my ModelRoot class. Referring to the attached graph, as an example this shows the class name "Substation" above the instance "SS1" and has a space for contained items to be displayed within it. >>mondrianShape | builder | builder := MOFormsBuilder new. builder column; center; fill; pref; grow. builder row; center; pref; fill; grow; row; center; pref; fill; grow; row; center; pref; fill; grow. builder x: 1 y: 1 add: ( MORectangleShape new text: #strippedClassName; textAlignment: #left; borderColor: Color white ) . builder x: 1 y: 2 add: ( MORectangleShape new text: #localName; textAlignment: #left ) . builder x: 1 y: 3 add: ( MORectangleShape new ) . builder x: 1 y: 3 add: ( MOChildrenShape new ) . ^builder shape In conjunction with the use of MOChildrenShape above, class ModelRoot also has method #addSubViewTo: which descends through contained classes - for example instance "primary" inside "T1" inside "SS2" inside "Figure 8..." >>addSubViewTo: aMOViewRenderer aMOViewRenderer node: self using: self mondrianShape forIt: [ self children do: [ :child | child addSubViewTo: aMOViewRenderer. ] ] My initial issues in migrating this to Roassal are: 1. Roassal appears to not provide any methods that have "using:" in them. 2. Roassal appears to not support MOFormsBuilder It may be that I am accessing to much internal methods. The code above was the result of evolutionary hacking as I was learning Mondrian. I would be happy to re-architect if someone can advise best practice for Roassal. cheers -ben

some Roassal use cases
by Ben Coman 05 Aug '12

05 Aug '12

Just to give you an idea of where I would like to end up... referring to the attached [1] & [2]. I am looking to be able to generate a first layout from data by applying a layout, but then mostly move nodes around and draw links manually - then save and load these layouts. I imagine that similar might be useful for software analysis wanting to intuitively arrange a few nodes to annotate together for printing purposes - saving different zoomed in "views" of the system under analysis. One thing I am contemplating is whether one of my "busbar" shapes could be defined to have several regularly spaced attachpoints, with the attachpoints themselves optionally visible - either full time or when hovering over a shape. Also I'd like to be able to group shapes that a layout can act on as a whole. A little different from the MOFormsBuilder, it would just be offsets relative to each other, to the point where interactively you could multi-select nodes and "Group" them to be acted on by a layout as a whole. I've also marked a couple of other ideas on these attached files.

migrating to roassal - MOArrowedOrthoVerticalLineShape
by Ben Coman 05 Aug '12

05 Aug '12

I am usings the code to produce the attached image. view shape: (MOArrowedOrthoVerticalLineShape new). view edges: inheritance from: #superclass to: #yourself. How do I achieve that with Roassal? And just to document something I got working... previously to hide lines while keeping the layout I was using... view shape: (MOStraightLineShape new color: Color white). view edgesFrom: [ :xx | xx - 1 ]. and now... (view edgesFrom: [ :xx | xx - 1 ] ) do: [ :edge | edge - ROEdge ] . cheers -ben

Quest for Hierarchical Data
by Mircea Filip Lungu 05 Aug '12

05 Aug '12

Hello Moosers, As you already know, Dennis is working on the hierarchical graph data structure and its great associated visualization in Pharo :) We have been testing his code on software systems which have an inherently hierarchical structure with low level relationships propagating up along the package structure, but also thought we would try it on a different type of hierarchical data. The two contributions (the HG data structure & the visualization) are after all independent of the domain model. Do you know of any data sources that have the following two properties? 1. There exists a set of relationships between low level, leaf entities 2. The low level, leaf entities can be aggregated along containment relationships One example would be trade relationships existent between companies, can be aggregated to regions, countries, continents... If you are aware of such a data set, we'd offer a beer for the information :) Cheers! M.

Roassal nested edges
by Ben Coman 05 Aug '12

05 Aug '12

Just interested in learning more about the internals of Roassal. I see this comment in ROElement>>positionRelativeTo: anElement "Return the position of myself against the position of one of my parent, anElement. The returned position is relative to it." "This method is useful to draw edges that are nested" How do nested edges fit into the architecture ?
