avoid flickering in refresh panel

[crosemffet]

hello and thanks again for your support.
after certain operation I need to refresh the panel content.
actually I'm using:
$('#p_central').panel('refresh','myLocations.php');
works like a charm, but the problem is refresh operation produces a flickering in the content.
any way to refresh smoothly..?

The code below shows how to custom the loading action.

Code:

$('#p').panel({
	onBeforeLoad: function(param){
		var target = this;
		var state = $.data(target, 'panel');
		var opts = state.options;
		state.isLoaded = false;
		opts.loader.call(target, param, function(data){
			var content = opts.extractor.call(target, data);
			$(target).panel('clear');
			$(target).html(content);
			$.parser.parse($(target));
			opts.onLoad.apply(target, arguments);
			state.isLoaded = true;
		}, function(){
			opts.onLoadError.apply(target, arguments);
		});
		return false;
	}
})

jarry, thanks for your reply. it works like a charm, the refresh go smoothly, the only problem is the panel title and panel icon breaks. I can't understand the reason. I'm uploading 2 images, the first is before using your script, and the second one is after using your script. you can notice the problem in the panel. maybe you can help me to find a solution.
here's my code, in case you need it to understand the situation,

<div id="p_north" data-options="region:'north',href:'_homeNorth.php'" style="height:40px;overflow:hidden"></div>
<div id="p_south" data-options="region:'south',collapsible:false,loadingMessage:'',href:'_homeSouth.php'" style="height:30px;overflow:hidden"></div>
<div id="p_west" data-options="region:'west',collapsible:false,loadingMessage:'',href:'_homeWest.php'" title="'.$textotg[50].'" style="width:300px;overflow:hidden"></div>
<div id="p_central" data-options="region:'center',title:'Main Title',loadingMessage:'',href:'_homeCentral.php',tools:[{iconCls:'icon-reload',handler:function(){$('#p_central').panel('refresh');}}]" style="overflow:hidden"></div>

thanks you in advance,
