Thanks for your response.
I think "featureunhighlighted" event sould be triggered in my case,
but I don't know for other cases.
Anyway I found a way to workaround the problem by writing my own
control for highlighting. I started from an example found on the web.
Here it is :
OpenLayers.Control.OverRejet = OpenLayers.Class(OpenLayers.Control,
{
layer: null,
defaultHandlerOptions: {
'delay': 2000,
'pixelTolerance': 1,
'stopMove': false
},
initialize: function(layer, options)
{
this.layer = layer;
this.handlerOptions = OpenLayers.Util.extend(
{}, this.defaultHandlerOptions);
OpenLayers.Control.prototype.initialize.apply(
this, arguments
);
this.handlers = {
feature: new OpenLayers.Handler.Feature(
this,
this.layer,
{
'over': this.over,
'out' : this.out
},
{}
)};
},
draw: function() {
return false;
},
activate: function() {
this.handlers.feature.activate();
},
deactivate: function() {
this.handlers.feature.deactivate();
},
over: function(feature) {
var rejet = feature.rejet;
if (rejet != null) {
rejet.showTooltip();
}
},
out: function(feature) {
var rejet = feature.rejet;
if (rejet != null) {
rejet.hideTooltip();
}
});
Then I configure this control for my layer :
var highlightControl = new OpenLayers.Control.OverRejet(layer);
map.addControl(highlightControl);
highlightControl.activate();
This does what I needed so no more problem for me ;)

Olivier
