Long click event?

[Anna PS]

Hi there

I'm building a mobile application that involves routing. I would like to allow users to set markers on a map with a long-click (aka taphold, aka click and hold for >500ms) event.

You can see the interface here: http://cyclestreets.darkgreener.com/route.html

Currently I set markers on the 'dblclick' event: I previously used 'click' but found the usability was poor as it was much too easy to set markers accidentally, just by touching the screen as you moved the phone in your hands. 

Is there a way I could approximate a long-click event in the Google Maps v3 API? Perhaps doing something clever with timers? 

Long-click seems like a very handy event for mobile users, so it would be a great addition to the API. 

many thanks

Anna

Absolutely. I been doing it with something like:

google.maps.event.addListener(map, 'mousedown', function(){
clearTimeout(map.pressButtonTimer);
map.pressButtonTimer = setTimeout(function(){
doSomethingUseful();
}, 500);
});

clearTimeout() is essential. Note that you can often see 'if()'
statement with clearTimeout but that is not needed by Ecma standard.

map.pressButtonTimer is a variable name, not any API property.

Thanks, but this doesn't work for me: it fires on single clicks and
simply waits for 500ms before firing doSomethingUseful.

I really need a 'taphold' event: i.e. only fires if the user clicks
the map *and deliberately holds* it for 500ms.

That way, you can be certain the user hasn't just touched the map
while moving the phone between hands - they really mean to fire the
event.

I think this would be a really useful event for Google Maps.

Any ideas, anyone?

Something like this?

Did you try to implement this? It wasn't terribly difficult.
