Hi Andreas,
thank you for your help!
I have alreade tried to use the SelectFeature class. But a strange behaviour
appears when combing it with the DragFeature: i can click the feature only
once. If i don't use the DragFeature the SelectFeature works like expected. I
created a working example of that phenomena, see at the bottom. If you disable
the dragFeature the selectFeature works like expected, maybe this is even a
bug...?
Cheers,
Christoph
layer = new OpenLayers.Layer.Vector("layer");
map.addLayers([layer]);
drag = new OpenLayers.Control.DragFeature(layer);
map.addControl(drag);
drag.activate();
click = new OpenLayers.Control.SelectFeature(
[layer],
{
clickout: true, toggle: false,
multiple: false, hover: false,
toggleKey: "ctrlKey", // ctrl key removes from selection
multipleKey: "shiftKey" // shift key adds to selection
}
);
map.addControl(click);
layer.events.on({
"featureselected": function(e) {
alert('selected');
},
"featureunselected": function(e) {
alert('unselected');
}
});
click.activate();
ftr = new OpenLayers.Feature.Vector(new OpenLayers.Geometry.Point(1, 2)); // an
icon
layer.addFeatures([ftr]);
