RE: [Dynapi-Widgetdev] DynBuilder managers & modules issue

[Pascal <pb...@oi...>]

A layout manager would be a child it self (of the document, or another
layer)  It would listen to it's parent's resize event, and when that happens
invoke an event on the child-layers/widgets it contains.

So I think it's basically a two-way direction.. listen for actions to act
on, and then invoke corresponding actions on it's children.  I think this
means that widgets should have methods for stuff like  redraw() or repaint()
which redraws the widget for the (new) x,y and w,h values.
