2525C symbol highlight/ selection

CarlosColón-Maldonado

I've taken the long road towards getting to the bottom of this on my own, but I'm running into a brick wall, especially now that the release version of Runtime makes no difference on these two issues:

1. The original intent of implementing 2525C symbol highlighting appeared in the prereleased version, though it did not work, but now it seems to have vanished from the API altogether. Is it going to be available eventually? If it is available now, what am I doing wrong (code below)?

    Message msg = messageProcessor.createMessageFrom(index);
    if (msg != null) {
     msg.setProperty(MessageHelper..MESSAGE_ACTION_PROPERTY_NAME,
       "highlight");
     messageProcessor.processMessage(msg);
    }

2. In order to have a better interactivity with the above, I'd like to be able to highlight the symbol that I choose by mouse-clicking to it. I am familiar with your sample app the makes a simple selection to polylines that are stored on a GraphicsLayer being managed by a HitTestOverlay with the use of HitTestListeners. I figured that, since the GroupLayer, now called MessageGroupLayer, creates GraphicsLayer types for each message type it handles, I could use something like below to determine symbols within a mouse-click region. Problem? The method GraphicsLayer.getGraphicIDs(x,y,tol) throws a null exception every time. Help?

    Layer[] layers = messageGroupLayer.getLayers();
    List<Graphic> selected = new ArrayList<Graphic>();
    for (Layer layer : layers) {
     if (layer.getClass() == GraphicsLayer.class) {
      float x = (float) screenPoint.getX();
      float y = (float) screenPoint.getY();
      GraphicsLayer gLayer = (GraphicsLayer) layer;
      try {
       int size = gLayer.getGraphicIDs().length;
       int[] list = gLayer.getGraphicIDs(x, y, 100);
       for (int id : list) {
        if (gLayer.isGraphicSelected(id))
         selected.add(gLayer.getGraphic(id));
       }
      } catch (Exception e1) {
       System.err.println("Cannot collect graphics: "
         + e1.getLocalizedMessage() + "\n");
       e1.printStackTrace();
      }
     }
    }
    System.out.println("Hit test: " + selected.size());

I would like to confirm that this issue has been solved in version 10.1.1 as follows:

Code:

@Override public void onMouseClicked(MouseEvent mouseEvent) {     for(Layer l : msgGroupLayer.getLayers()){      if(l instanceof com.esri.map.GraphicsLayer){       GraphicsLayer gl = (GraphicsLayer)l;       gl.setSelectionColor(Color.WHITE);       int[] ids = gl.getGraphicIDs(mouseEvent.getX(), mouseEvent.getY(), 0);       for(int i : ids){        gl.select(i);       }      }              }     super.onMouseClicked(event); }

To obtain the associated Message objects from the selected 2525C symbols, the message processor will have to be used to obtain them with the graphic objects from the graphics layer.

Unfortunately, the Java tool kit code does not allow the flexibility of desired behavior once the selected graphics are set as selected and highlighted with the desired color out-of-box. Therefore, the HitTestOverlay and associated objects will have to be re-created and modified to achieve it.

Thanks for the support.
