Hi guys,

I'm using Roassal to build a visualization that looks like the following:

http://www.xconomy.com/wordpress/wp-content/images/2012/11/skeuo-calendar.png

I create two ad-hoc layouts (i.e., extending the ROGridLayout) to individually layout days inside months and months inside years.

I have a piece of code that looks something like:

view shape rectangle withText.

view nodes: nodes forEach: [ :aGroupOfObjects | | innerNodes |

innerNodes := do something with aGroupOfObjects.
...
view shape rectangle size: 25; withCenteredText.
...
view nodes: innerNodes.
view layout: ROMonthLayout new.
]

view layout: ROYearLayout new.

view edges: ...

Notice that I want the both the outer node (i.e., the month container) and the inner nodes (i.e., days) with labels.

The problem is that when I set both nodes with labels the view takes time to be generated and interactions become impossible (i.e., the whole image actually becomes slow and you can no longer drag around shapes in the view).

I explored the issue a little bit and discovered that it might be something related to ROShape>>chainedDrawOn:for: and the way Roassal handles shapes with "nested" shapes (i.e., when 'next' is not a RONullShape .

I inspected one of my outer nodes and discovered that I have a chain such that 'outerNode next' is a ROLabel and the ROLabel has a ROChildrenShape as next and the next of the ROChildrenShape is a RONullShape .

Have you ever experienced such a problem? Do you know how can I handle that? Do you see any potential problem in the snippet I posted above?

Cheers and thanks in advance,
Roberto
