Virginie,
FWIW:
I've taken a similar approach to Aaron, but with one caveat:
context.removeLayer did not appear to work for me when I wanted to
remove GridCoverage layers (for normal layers it works fine). In that
case of removing GridCoverage layers, the best I could come up with was
to trash the entire context and rebuild.
HTH,

I've done quite a bit of layer inter-changing and I have never managed
to get any of the removeAll() functions to work. I ended up creating
a hash-map to store my layers, then looking them up either
individually and taking the from the context, or just using this
function to remove them all (layers is a java.util.HashMap):
if(layers!=null){
Collection colVal=layers.values();
Iterator itVal=colVal.iterator();
while(itVal.hasNext()){
//remove one layer at a time
context.removeLayer((MapLayer)itVal.next());
}
//clean out the Hashmap for the new layers
layers.clear();
}

behavior of a StyledMapPane
Hi Peter!
I've made a class that extends StyledMapPane and I have overridden
the method protected void mouseSelectionPerformed(final Shape
area). When I click or draw a rectangle on the map (zoom in), I
would like to remove all the layers and add new layers (created
with the new bounding box). I manage to calculate the new
coordinates but don't manage to remove the layers. I use
separately the methods removeAll() or
getRenderer().removeAllLayers() but it doesn't work.
Could you help me to remove the old layers and to add new ones?
Thanks!
Virginie

If you make a new class that extends StyledMapPane, you can
override the
method:
protected abstract void selectionPerformed(int ox, int oy, int px,
int py);
I think that should accomplish what you want.
As a side note to any developers that may be listening, I would
love it
if the selectionPerformed method could also provide the original
mouse
event (e.g. protected abstract void selectionPerformed(MouseEvent
oEvent, int ox, int oy, int px, int py)). I would extend
MouseSelectionTracker myself, but it is not declared public.

Hi All !
The data displayed in my StyledMapPane result from a WMS request. I
would like to remove the default behaviour of the zoom by making
a new
request with the new bounding box etc.
I have added a zoomChangeListener, the code written in the
zoomChanged
method doesn't work: mapPane.getRenderer().removeAllLayers();
and then I add new layers to the mapPane.
Someone could help me ?!
Thanks!
