[news.eclipse.tools.gef] Draw2D - AbstractLayout.isObservingVisibility()

[Felix Noz <fnoz@xxxxxx>]

Hello,

I'm new to Draw2D and I need a layout that observes the visibility of 
the children of a figure.
The children must be laid out vertically with streched horizontal axis. 
Unfortunately both Flow- and ToolbarLayout don't observe visibility. So 
what's the best solution:
subclassing those layouts?
writing a complete new layout?
remove invisible children and add them again when visible?
