You have to hook into the functions "OnMapLoading" and "OnMapLoaded":
//Save a copy, in case there are multiple hookups
mapLoadingCallBack = map.GetMapFrame().OnMapLoading;
mapLoadedCallBack = map.GetMapFrame().OnMapLoaded;
//Assign new functions
map.GetMapFrame().OnMapLoading = hijacked_onLoading;
map.GetMapFrame().OnMapLoaded = hijacked_onLoaded;
You can then implement your handler like this:
function hijacked_onLoading()
{
try {
//Perform you own stuff here...
} catch (e) {
}
//Call the previous owner
if (mapLoadingCallBack != null)
mapLoadingCallBack();
}
