Box-in-Box view for compartment [message #172789]

Mon, 18 February 2008 09:43

Eclipse User

Hello all,
I have requirement where we are required to display recursively the
compartment contaning the nodes which has child compartment with
node..something like a treeViewer

I would like to display compartments in Box-in-Box view appraoch
|------------------------------|
| comp1 |
| |------comp2------------| |
| | ----- ----- | |
| | |comp3| |comp4| | |
| | | | | | | |
| | |-----| |-----| | |
| | |comp5| | |
| | |-----| | |
| |----------------------- |
| |
|------------------------------|

Please let me know what is best approach to achieve this ? Or is there any
better layout for recursive compartment?

Hello BG,

Just Define NodeMapping containing ChildReference referensing this NodeMapping
as "referencedChild".

Another way to visualize tree-like structure is by using "Visualize containments
as links" GMF feature: http://www.eclipse.org/gmf/new/gmf-new-1.0.php

Hello Mr Shatalin,
Thanks for reply,I am following the same " Endless/recursive hierarchies"
the output also appearing fine.But it appears as stack one over the other
Rather i would it to be something similar
"http://www.eclipse.org/gmf/new/gmf-new-1.0.php" .Mindmap example .To
achive this what layout do i need to choose ?.As i have nested hireachy
upto 10(Compartments).I tried with ListCompartmentEditPart, it comes in
row ...

Cuurently iam using the ShapeCompartmentEditPart....? Do i need write some
editpolices or do i need createFigure method ResizableCompartmentFigure
result = (ResizableCompartmentFigure) super.createFigure()........;.

Also i have another query.
When i tried to pull a box [element] from one compartment it comes out ?
But same thing doesn't happen the Mindmap example ?

In this example sub-nodes probably were manually layed-out.

That was my suggestion.

> Cuurently iam using the ShapeCompartmentEditPart....? Do i need write
You should probably take care on layout process (popup menu/Arrange all)

> But same thing doesn't happen the Mindmap example ?
I think the reason is: in your model corresponding nodes can be created on
top of diagram.
AFAIR it is not possible to change this behavior without manual code modification
for now.

hi alex,

this "Visualize containments as links" but I it's not described there
how I can model it?

Just leave TopNodeReference.containmentFeature blank and use this containment
feature to define reference-only link.

Hello Mr Shatalin,
Iam now using the ArrangeAll request to arrange the compartments
i.e
ArrangeRequest arrangeRequest = new
ArrangeRequest(ActionIds.ACTION_ARRANGE_ALL);

//DiagramEditor diagramEditor1 = (DiagramEditor)
getActEditorPart();
DiagramEditPart diagramEditPart =
diagramEditor.getDiagramEditPart();

SelectInDiagramHelper.activateDiagram(diagramEditPart.getDia gramView());
List<?> l = diagramEditPart.getChildren();

Command arrangeCmd = diagramEditPart.getCommand(arrangeRequest);
arrangeCmd.execute();

But is just arranging the first compartment. Is does not arrange the inner
compartments.

I want something similar to happen like combination of
"selectall/arrangeall".How can i achieve this ?.

Regards
BG

Hi Alex,

I have a tricky situation in modelling and desinging Parent - Child
relationship.

The root of my model has the 1-1 containment reference with Type A, it
cant hold Type B and Type C.

"Type A" which shares 1-* containment reference with "Type B" and "Type B"
has 1-* containment reference with "Type C"

I dont want the Box in Box view depicting the "Type B" - "Type C"
relationship , i want them to be depicted as links.

The idea is to have OpenDiagram bevahior for "Type A" and within that I
will model elements "Type B" and "Type C" as separate diagram elements and
use links to connect "Type B" and "Type C"

Is this possible to achieve this in GMF and depicted diagramatically ?? If
yes can you provide some insight to it or any pointers will help.

Reagrds,
Kamesh

Hello Kamesh,

Try modeling Type B -> Type C containment as a link, but you can face some
future problems. It definitely works then diagram element (Type A) can not
contain "phantom" node (Type C) but you can see some propbelms in your situation.
I suggest you to try it and then fix an errors in generated code.

Hi Alex,

Whats the problems that could potentially occur ? Can you please explain
wht are they ?

Whats the best practice in this situation to model this kind of
relationships so that we can express it neatly in the GMF.

Hello Kamesh,

I suppoose destination Type B instance to jump into resource root on deleting
the link representing containment.
You can face some other problems - I never tested this situation myself.
Feel free to file a bugzill arequests to correct these issues.

Hi Alex,

I am now terribly confused, how am suppose to define the Containment as
Links.

I have attached the Models for your reference - the link part is dirty (
where the confusion exists)

Can you please clarify the Containment Links in this context . I am not able
to follow how to do it from the newgroups post .

I hope we can then post it as an article in the GMF Wiki to help others like
me.

Please let me know am doing something wrong or is there a trouble with my
model.

Regards,
Kamesh

Hello Kamesh,

you have to:
1. Stecify 2 top-level nodes for "State", "City" leaving "containmentFeature"
blank
2. Create 2 link mappings with "targetFeature"s set to: "states", "cities"

As a result you should be able to:
- create new Countries on diagram
- create new States on diagram and connect existing Countries with newly
created States by first type of the link
- create new Cities on the diagram and connect existing States with newly
creates Cities by second type of the link
