I have a different answer than Jesse (which may mean I am wrong - heh).
I would make a CompositeCommand that does all the work you want to in
one go ... the map will only have a chance to respond when the composite
command is finished its work.
This is the point where Jesse either says "you are wrong jody" or "that
is a good idea".

Hello,
we have built a widget that replaces some of the functionality
provided by the LayersView. It's basically a combo box with the
current layers, and which sets the visibility for all layers to be
false, except the one chosen by the combo. Furthermore, on selecting,
the map should zoom to the layer's bbox. Like this (in pseudo):
1) User selects layer on combo?
2) for each layer
if layer is not selected layer -> setVisible( false )
else setVisible( true )
map refreshes here!
3) map.setBbox( selectedLayer.getBbox() )
map refreshes again!
This all works fine. However, there are two events (or more) being
triggered: layer visibility (implies a map refresh), jump to bbox
(another map refresh).
Is there a way to temporarily disable map refresh? As in
1) map.setFiringEvents( false );
2) Turn layers' visibility on/off
3) map.setBbox( selectedLayer.getBbox() )
4) map.setFiringEvents( true );
5) map.refresh()
Thanks in advance,
Ugo
