Re: [OpenLayers-Users] Selecting a feature AND drawing a point]

Wed, 06 Feb 2008 02:12:48 -0800

Alright. I'll check it. What I'd like to know is if in your opinion it is the right way to do this. Or is better to place a marker? I suppose that with the marker the problem would be inverse, to pass the coords.

Which is for you the cleanest way to inform the suer he chosen that point?

Thanks

In the feature class there exists a 'geometry' class that contains a
LineString: pretty much [x1,y1,x2,y2,],[]..]; the start,end for each vertex
on the feature. these coordinates are in whatever coordinate system the base
layer is in, but you can use the map object and 'getViewPortPxFromLonLat()'
or something similar to construct a Pixel object....

Hi I was trying to :

1) selecting a feature

2) draw a point where i selected this feature

for 1) i do somewhat like this:

map.events.register('click', map, function (e) {

//build a Pixel using e.xy.x and y

//selection through ajax of my wfs feature

}

now, if i want to add a feature, i must add

	drawPoint.featureAdded = function(feature) {
	//feature is the geometry
}

What i don't understand is how to get from 'feature' the coordinates  
to build the Pixel object. In the documentation I saw there's a  
property, 'lastDown' who returns a pixel, but logging this properties  
I always get 'undefined'.

Anyone could help me?

Thanks
