Hi all,
I finally succed, i've solve my problem by making my own object. I extended
the Control Class and had a new control call tooltips.
Here is the new class :
/*
*
* Purpose: extends OpenLayers API (toolTips)
* Add New Control ToolTips
* Author: Van De Casteele Arnaud
* Date: february 2008
* Version: 0.1
*
*/
/**
* @requires OpenLayers/Control.js
*/
/**
* Class: OpenLayers.Control.MousePosition
*
* Inherits from:
* - <OpenLayers.Control>
*/
OpenLayers.Control.ToolTips = OpenLayers.Class(OpenLayers.Control, {
/**
* Property: element
* {DOMElement} The DOM element that contains the toolTips Element
*/
element: null,
/**
* Property: text color
* Can be a text as black or hexadecimal color as #000000
* {String}
*/
textColor: "black",
/**
* Property: bold text
* {String}
*/
bold : false,
/**
* Property: Opacity
* {String}
*/
opacity : 100,
/**
* Property: background color
* Can be a text as white or hexadecimal color as #FFFFFF
* {String}
*/
bgColor: "white",
/**
* Property: Padding of the div
* {String}
*/
paddingValue : "2px",
/**
* Property: lastXy
* {<OpenLayers.LonLat>}
*/
lastXy: null,
html : null,
/**

*
* Parameters:
* options - {DOMElement} Options for control.
*/
initialize: function(options) {
//Extend with new arguments
var newArguments = [];
OpenLayers.Util.extend(this, options);
OpenLayers.Control.prototype.initialize.apply(this, arguments);
},
/**

destroy: function() {
if (this.map) {
this.map.events.unregister('mousemove', this, this.redraw);
