Layout issues

[Scott Palmer]

I found my original problem.  One of my components called requestLayout on some of it's children in response to layoutChildren.  I changed that to a direct call to layoutChildren and that did the trick.

I'm still struggling with odd sizing behaviour - when I remove content from within a container the container still seems to think it counts as far as the layout bounds go.  It's odd as I can see the container shrink because it knows some of the content has been removed, but there is another bit of content that is clearly defining the size of the parent even though it has been removed from the parent.

Then I switched to listening to the pane's width and height properties and then call a custom relayout() method. That works perfectly. Furthermore, by using binding to such properties combined with the calculation features, it now is a breeze to get stuff laid out.

It's like something is always in the list of "dirty" nodes and is forcing a re-layout.   I don't understand this.  I've googled but I can't find a decent tutorial for implementing custom containers or custom layouts.
