Hi,
You can move polygon rather than erasing it and create new. For
example you can make function moveCurrentMarker (which is almost the
same as highlightCurrentMarker) and running it on "drag" event:
google.maps.event.addListener(marker, "drag", function(){
currentMarker = marker;
moveCurrectMarker();
});
Code of moveCurrentMarker:
function moveCurrectMarker() {
var markerPoint = currentMarker.getPosition();
var mapNormalProj = overlayView.getProjection();
var mapZoom = map.getZoom();
var polyPoints = [];
var clickedPixel = mapNormalProj.fromLatLngToDivPixel
(markerPoint);
var polySmallRadius = 20;
var polyNumSides = 20;
var polySideLength = 18;
for(var a=0; a<(polyNumSides+1); a++){
var aRad = polySideLength * a * (Math.PI/180);
var polyRadius = polySmallRadius;
var pixelX = clickedPixel.x + polyRadius * Math.cos(aRad);
var pixelY = clickedPixel.y + polyRadius * Math.sin(aRad);
var polyPixel = new google.maps.Point(pixelX, pixelY);
var polyPoint = mapNormalProj.fromDivPixelToLatLng
(polyPixel);
polyPoints.push(polyPoint);
}
highlightCircle.setPaths(polyPoints);
}
There are still some problems with event 'mouseover' and 'click' -
when I dropped 'click' event the example still works. 'Mouseover'
event sometimes causes, that there are two polygons in the same place
in the same time - so opacity is higher (but only for the second :)
Cheers,
