btw. here is the adapted code example for anyone who might be interested in it:
layer = new OpenLayers.Layer.Vector("layer");
map.addLayers([layer]);
drag = new OpenLayers.Control.DragFeature(layer);
map.addControl(drag);
//drag.activate();
drag.onComplete = function(f) {
drag.deactivate();
click.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) {
drag.activate();
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]);
