Dear All
I'm building a iPhone application that uses google maps in a UIWebView
I created a class that gets the iPhone screen touch events and
converts these to google maps javascript.
It works fine exept for one thing.
My map contains markers from a KML parsing through geoXml.
When I click on the iPhone display, I want to fire a map "click" event
to the map so :
- I can open an infowindow if the click was over a marker
- I can update the position of the center marker if the click was on
the map
Here is what I do :
1) I add a click listener to the map
GEvent.addListener(map, "click", function (overlay, latlng)
{ MapClickHandler(overlay, latlng); } );
2) I create the handler as follow :
function MapClickHandler(overlay, latlng)
{
// the map has been clicked (not a marker)
// if a marker was clicked (latlng would be null)
if(latlng)
{
// update current lat/long
Lat = latlng.y;
Long = latlng.x;
// Display new position marker
UpdateCurrentPositionMarker();
// the map has been moved
zoom = map.getZoom();
// reload the kml now
reloadKml();
}
}
3) when the iphone screen is clicked, I call this javascript :
The following javascript converts the pixel coordinates to latlng and
fires a click event to the map.
function iPhoneScreenClicked(pixX, pixY)
{
var newCenterPixel = new GPoint(pixX, pixY);
var newCenterLatLng = map.fromContainerPixelToLatLng
(newCenterPixel);
// trigger an event to the map with a unknown overlay !
GEvent.trigger(map, "click", undefined, newCenterLatLng); <<<
PROBLEM HERE
}
Unfortunatelly this does not work since the parameter overlay is lost
as soon as I pass something as a parameter in the function.
I tried different ways, unfortunatelly never gets a working solution
GEvent.trigger(map, "click", , newCenterLatLng); << WORKS BUT RESULTS
IN JS ERROR
GEvent.trigger(map, "click", '' , newCenterLatLng); << OVERLAY IS
LOST
I was thinking about a function that could retrieve an overlay at a
given latlng so I can update my function to :
function iPhoneScreenClicked(pixX, pixY)
{
var newCenterPixel = new GPoint(pixX, pixY);
var newCenterLatLng = map.fromContainerPixelToLatLng
(newCenterPixel);
GEvent.trigger(map, "click", map.getoverlay(newCenterLatLng),
newCenterLatLng); <<< HOW TO DO THAT ?
}
Any help would be greatly appreciated, I'm stuck for 3 days on this !
thanks to all
