I have a tool that gets map coordinates from a mouse click and then does some work. In code add a marker symbol at the location the person clicked. The user may click multiple times prior to exiting the tool. On exiting I would like the overlay to be cleared.
To add the points I'm doing this:
var disposable = await QueuedTask.Run(() =>
{
return mapView.AddOverlay(myPoint,
SymbolFactory.ConstructPointSymbol(ColorFactory.CreateRGBColor(255,255,0), 10.0, SimpleMarkerStyle.Cross).MakeSymbolReference());
});
Do I need to keep track of all the disposable vars (perhapse in an array) to do:
disposable.Dispose();
for each maker?
What I would like is a mapView.ClearOverlayAsync() command similar to the existing
mapView.ClearSketchAsync();.
Ideas?
