Polylines widths and click events

[Marc Lacoursière]

Hello!

I have a mapping application that draws polylines having a width of 2
pixels. My current goal would be to allow users to select them easily.
Here is how I register the click events:

google.maps.event.addListener(path, 'click', function() {
Ext.Msg.alert('click on track');
});

It's working very well, except that the user has to click precisely on
the little line to make it work. As a programmer, I can consider
myself as a power clicker, but I sometimes have a hard time to aim
effectively. That's far from being user friendly.

Is there a way I could still draw thin lines but have a wider click
area?

Thank you very much, I love the new API!

Hi Marc,

I suggest rendering a thicker, virtually-transparent polyline underneath.  If you set strokeOpacity to 0.01 and strokeWeight to eg. 5, the line should be clickable but not visible.  I haven't tried this though, so I'd be interested to hear if this works for you.

Cheers

Ben

I have tried it at 25 strokeWeight... it works very well for now.

var path = new google.maps.Polyline({
path: trackpoints,
strokeColor: "#FF0000",
strokeOpacity: 1.0,
strokeWeight: 2
});

path.setMap(map);

var widePath = new google.maps.Polyline({
path: trackpoints,
strokeColor: "#FF0000",
strokeOpacity: 0.01,
strokeWeight: 25
});

widePath.setMap(map);

google.maps.event.addListener(widePath, 'click', function() {

Ext.Msg.alert('click on track');
});

Thanks Ben!
