menu and grid

[wehtam]

Hello
In my grid I have a tbar like this :

tbar : [ new Ext.form.ComboBox({
				fieldLabel: 'Zone géographique',
				store: new Ext.data.SimpleStore({
				fields: ['id', 'libelle'],
				data : Ext.dataZoneGeoOffresSpeciales.Zone  // from states.js
				}),
				displayField:'libelle',
				valueField: 'id',
				id : 'zone',
				hiddenName: 'IdZoneGeoOffresSpeciales', 
				typeAhead: true,
				labelStyle: 'width:170px;',
				mode: 'local',
				triggerAction: 'all',
				emptyText:'Choisir...',
				selectOnFocus:true,
				forceSelection: true,
				 width: 250,
				allowBlank:false
				}),{
            text:'Nouvelle offre spéciale',
            tooltip:'Ajouter une nouvelle offre spéciale',
            iconCls:'add',
			handler: addCate
        }]

I would like call a function when I select a value in may combobox, how can I do that ?
Thanks

ComboBox has a change or select event that you want to subcribe to.

add something like

listeners:{
  change:function(combo, ewVal, oldVal) {
    // do something
  }
}

to the config of your ComboBox.
