Hi,
I'm trying to create a control that only triggers an action whit Ctrl
+ click. But the control gets triggered with and without pressing the
Ctrl key.
Here is a minimum example, adapted from the Openlayers Click Event
example. Any ideas?
Thanks.
var MyControl = OpenLayers.Class(OpenLayers.Control, {
initialize: function(options) {
OpenLayers.Control.prototype.initialize.apply(this, arguments);
this.handler = new OpenLayers.Handler.Click(
this, {
'click': this.trigger
},
{
'single': true,
'double': false,
'pixelTolerance': 10,
'stopSingle': false,
'stopDouble': false,
'keyMask': OpenLayers.Handler.MOD_CTRL
}
);
},
trigger: function(e) {
var lonlat = map.getLonLatFromViewPortPx(e.xy);
alert("You clicked near " + lonlat.lat + " N, " +
lonlat.lon + " E");
}
});
var map;
function init(){
map = new OpenLayers.Map('map');
var ol_wms = new OpenLayers.Layer.WMS( "OpenLayers WMS",
"http://vmap0.tiles.osgeo.org/wms/vmap0?";,
{layers: 'basic'} );
map.addLayers([ol_wms]);
map.zoomToMaxExtent();
var click = MyControl();
map.addControl(click);
click.activate();
}
