I patched the code (my local checkout, although I'd like to see this
contributed) as follows:
/**
* Add an overlay to this map.
*
* @see GOverlay
* @see GMarker
*
* @param overlay
*/
public void addOverlay(GOverlay overlay)
{
overlay.setGMap2(this);
overlays.add(overlay);
}
/**
* Remove an overlay from this map.
*
* @see GOverlay
* @see GMarker
*
* @param overlay
*/
public void removeOverlay(GOverlay overlay)
{
overlays.remove(overlay);
}
(I added the removeOverlay method)
Then, I was able to do this, which works great:
mapPanel.addClickListener(new ClickListener() {
private static final long serialVersionUID =
-7743409010362331350L;
@Override
public void clickPerformed(ClickEvent clickEvent,
AjaxRequestTarget target) {
double lat = clickEvent.getPoint().getLat();
double lng = clickEvent.getPoint().getLng();
latLbl.setModelObject(lat);
lngLbl.setModelObject(lng);
map.removeOverlay(mMarker);
// when they click, it should remove the old one, and add
the new one in the clicked location
GLatLng point = new GLatLng(lat, lng);
map.addOverlay(mMarker = new GMarker(point));
map.setCenter(point);
if (target != null) {
target.addComponent(latLbl);
target.addComponent(lngLbl);
target.addComponent(mapPanel);
}
}
});

With GMap2, how do I remove an overlay in a click event?
I need to be able to do this:
mapPanel.addClickListener(new ClickListener() {
private static final long serialVersionUID =
-7743409010362331350L;
@Override
public void clickPerformed(ClickEvent clickEvent,
AjaxRequestTarget target) {
double lat = clickEvent.getPoint().getLat();
double lng = clickEvent.getPoint ().getLng();
latLbl.setModelObject(lat);
lngLbl.setModelObject(lng);
//map.removeOverlay(memberDot); // this is the GMarker in
it's original location
// when they click, it should remove the old one, and add
the new one in the clicked location
map.addOverlay(new GMarker(new GLatLng(lat, lng)));
if (target != null) {
target.addComponent(latLbl);
target.addComponent(lngLbl);
target.addComponent(mapPanel);
}
}
});
Thank you!
