Does anyone have a non-trivial OverlayView WITHOUT using an "idle"
event listener ????
Google has refused to make it automatic like the "redraw" method in V2
with "force=false".
I cannot imagine doing anything useful in an OverlayView without an
"idle" event listener. It is the most efficient way to update the
OverlayView at the completion of a "drag" or a "pan" or a "zoom". Any
realistic OverlayView will have to insert or remove elements depending
on the change in the visible portion of the map. I suppose a really
trivial OverlayView might not bother to update the view.
But, if an "idle" method is not defined, the API will not attempt to
call it. The "excess overhead" argument has no merit.
if (this.idle) this.idle();
One simple statement in the API could eliminate explicitly defined
"idle" event listeners for every OverlayView. Event listeners waste
resources & cause memory leaks. Adding a single statement to the API
will save resources & reduce memory leaks without any impact on an
OverlayView without an "idle" method. The "onAdd" method is analogous
& optional. If it does not exist, it is not called.
Google - please reconsider your decision.
