Thanks a lot,
It is a first step of what I want.
Excellent!
But, with this builder, it seems you need to have
twice the element on different layers to have a link between them.
And I would like to define my own edges between two layers like in a tree graph, could
you add it, please ?
I could add it, but well… my time is limited. The RTLayerBuilder is just a simple example
on how to define a builder. RTLayerBuilder is extremely simple. Actually, there is just
one important method (ie. longer than 2 lines of code):
-=-=-=-=-=-=-=-=-=-=-=-=
RTLayerBuilder >> renderIn: aView
| elementsLayer topLayer currentLayer |
"We draw the nodes"
elementsLayer := objectLayers collect: [ :objects | self elementsWithInteractionOn:
objects ].
elementsLayer do: [ :l | RTHorizontalLineLayout new horizontalGap: horizontalGap; on: l.
aView addAll: l ].
RTVerticalLineLayout new verticalGap: verticalGap; alignCenter; on: elementsLayer.
"We draw the edges from one layer to the layer above"
2 to: elementsLayer size do: [ :i |
topLayer := elementsLayer at: (i - 1).
currentLayer := elementsLayer at: i.
currentLayer do: [ :currentElement |
| aboveElements |
aboveElements := topLayer select: [ :el | el model = currentElement model ].
view addAll: (RTLine edgesFrom: currentElement toAll: aboveElements) ]
]
-=-=-=-=-=-=-=-=-=-=-=-=
I wrote this in 5 mn, and indeed, it can be improved. I recommend you to try to write you
own builder to make it fit with you needs.
By the way, how can I move the camera in the view ?
Have you tried RTCamera>>#translateBy:
Try this:
-=-=-=-=-=-=-=-=-=-=-=-=
| v menu |
v := RTView new.
v add: (RTEllipse new size: 50) element.
menu := RTMenuBuilder new view: v.
menu menu: '<-' callback: [ v canvas camera translateBy: -10 @ 0. v
signalUpdate ].
menu menu: '->' callback: [ v canvas camera translateBy: 10 @ 0. v signalUpdate
].
menu menu: 'V' callback: [ v canvas camera translateBy: 0 @ 10. v signalUpdate ].
menu menu: '^' callback: [ v canvas camera translateBy: 0 @ -10. v signalUpdate
].
v

Vincent, does this LayerBuilder solves your question?

Hi Vincent,
I am not sure to understand what you need exactly.
I just created a new builder, called RTLayerBuilder.
A simple example:
-=-=-=-=-=-=-=-=-=-=-=-=
| b |
b := RTLayerBuilder new.
b addLayer: 'ABC'.
b addLayer: 'BCA'.
b addLayer: 'DEFA'.
b open
-=-=-=-=-=-=-=-=-=-=-=-=
It gives:

By being a builder, you can enjoy all the facilities for defining shapes and
interaction:
-=-=-=-=-=-=-=-=-=-=-=-=
| b |
b := RTLayerBuilder new.
b shape circle
size: 20; withText.
b verticalGap: 30.
b horizontalGap: 40.
b addLayer: 'ABC'.
b addLayer: 'BCA'.
b addLayer: 'DEFA'.
b open
-=-=-=-=-=-=-=-=-=-=-=-=

https://www.iam.unibe.ch/mailman/listinfo/moose-dev Hi,
I would like to display a some elements by layers with Roassal.
Each element has a layer number (from 1 to 6 in the exemple) and is linked to elements
from other layers (green lines).
So each line of the visualization contains elements of one layer.
I have tried with all the treeLayout but I don't get a representation by the wanted
layers.
So I asked Usman and he tells me to use userDefinedEdges:.
So I defined virtual edges from all elements from a layer to all the elements to the next
layer.
And I get:
<image001.png>
All the nodes are on the good line but the linked between them (in green) are horribly
crossed.
Which virtual nodes should I add to make it works ? Or should I create/use a layout ?
Thanks for your answers,
Cheers,
Vincent
