Hi Arved, Nice to hear from you again. As you can see Keiron is doing most of the work, so he probably has some ideas for you. From my point of view, if you could look a bit at the LayoutManger classes (I've put a couple more in there) and the interfaces I'm starting to define with the Area classes, and make some comments it would help. The LayoutManager interface is still pretty simple. There are a few things bothering me though and I'd appreciate your feedback. One question is how much intelligence to put in the Area classes themselves and how much in the LayoutManagers which are creating them. For example, does the Area know how to calculate its own IPD and BPD when child areas are added, or does the LM tell it this? In the old scheme, the FO set dimensions on the Areas (in general). I always thought the Area classes should have done it. But now that we've moved layout intelligence into the LM classes, maybe its logical that they do the fancy calculations and set the results on the Area.
I think we also need some input on Property (ie. trait) management on the areas (or on the LM?). Keiron has started to specify some interfaces. Also maybe we need to look at the class hierarchy some. I've already noticed I'm doing a bunch of "casting" in the LM code, which isn't usually a good sign. My short-term goal is to get just enough LM code in place to get a feel for how it should work and to stabilize interfaces with the Area classes. I don't want to attack the more complicated cases yet, though I've got some ideas for float management in the back of my mind.
