Thank you Axel and Wolfgang for convincing me.
Perhaps, later, an CGA extention that allows for fully
dynamic layout (including changing parents, etc.)
could be developed later. It would clearly require a
lot more from it's backends.

The HBox and VBox you presented, David, seem to be overly simplified. For each widget in a box Gtk needs to know if the widget expands, stays its natural size or pads excess space. I guess other toolkits work differently.
You're right about that. Qt, what I'm most used to, defines this information to be an attribute of the object, which makes a lot of sense. Here is what I wrote earlier about that: http://article.gmane.org/gmane.comp.lang.haskell.gui/461
I think we should start with the easiest layout mechanism, which I suppose is the grid.
HBox and VBox are probably the first think I am going to implement in the example. If we have a clear-cut definition of a grid, I'll do that too. David J. Sankel
