How to show different popups on click and on mouseover? - popup

Question

The SelectFeature method in Control class provides a way of adding and removing popups on the Vector layer by listening to events featureselected and featureunselected respectively. Below shows a sample code that I obtained from an example in the openlayers website:
// create the layer with listeners to create and destroy popups
var vector = new OpenLayers.Layer.Vector("Points",{
eventListeners:{
'featureselected':function(evt){
var feature = evt.feature;
var popup = new OpenLayers.Popup.FramedCloud("popup",
OpenLayers.LonLat.fromString(feature.geometry.toShortString()),
null,
"<div style='font-size:.8em'>Feature: " + feature.id +"<br>Foo: </div>",
null,
true
);
feature.popup = popup;
map.addPopup(popup);
},
'featureunselected':function(evt){
var feature = evt.feature;
map.removePopup(feature.popup);
feature.popup.destroy();
feature.popup = null;
}
}
});
vector.addFeatures(features);
// create the select feature control
var selector = new OpenLayers.Control.SelectFeature(vector,{
hover:true, # this line
autoActivate:true
});
The code above will allow a popup to be shown upon mouseover on the Geometry object (icon or marker on the map). If the line hover:true is removed, the popup will be shown only upon a mouse click on the Geometry object.
What I want, is to be able to display one type of popup (example, an image plus a title) upon mouseover and another type (example, detailed description) upon a mouse click. I am not sure how this could be done. Some help would be much appreciated. Thanks.

Also, there another way, it's rather hack than correct usage of API, but seems to work. You can overwrite over and out callbacks.
var selectControl = new OpenLayers.Control.SelectFeature(vectorLayer, {
callbacks: {
over: function(feat) {
console.log('Show popup type 1');
},
out: function(feat) {
console.log('Hide popup type 1');
}
},
eventListeners: {
featurehighlighted: function(feat) {
console.log('Show popup type 2');
},
featureunhighlighted: function(feat) {
console.log('Hide popup type 2');
}
}
});
Here's working example: http://jsfiddle.net/eW8DV/1/
Take a look on select control's source to understand details.
