Hi,
I am using the latest uDig stable version 1.1.1 and I want to have the
following scenario:
I have a map with 4 layers:
Layer4 - Lines
Layer3 - Points type C
Layer2 - Points type B
Layer1 - Points type A
I want to select (with the typical selection Bounding Box) points on Layer 1
and layer 3.
Using the shift key I can select multiple layers (on this case Layer 1 and
layer 3) but when I use the selection tool only the features on the last
selected layer are selected.
I made a plug-in that goes through all the layers and select the features on
the defined bounding box. I can also restrict the selection to the layers
that are visible.
How can I restrict the selection to the selected layers (on this case layer
1 and 3)?
Here it is the code to select the features in all layers:
Envelope ev;
Coordinate start;
--------- on mouse pressed ----------
start=getContext().pixelToWorld(e.x, e.y);
ev.init();
ev.expandToInclude(start);
--------- on mouse released ----------
Coordinate end=getContext().pixelToWorld(e.x, e.y);
ev.expandToInclude(end);
for(int layerInd = 0; layerInd <= map.getMapLayers().size() - 1;
layerInd++)
{
ILayer layer = map.getMapLayers().get(layerInd);
if(layer.isVisible())
{
Filter filter = layer.createBBoxFilter(ev, null);
command =
getContext().getSelectionFactory().createSelectCommand(layer, filter);
getContext().sendASyncCommand(command);
}
}
Thanks,
Rui Alves
