How can i make my qtip decide on his own to Left or Right tip attribute

$('a.tooltip').each(function(){
    
    $(this).qtip({
        content: { url: 'includes/qtip.php?'+$(this).attr('rel')+' #'+$(this).attr('div'), text:'loading...'  },
        show: { delay: 400},
        hide: { fixed: true, delay: 200 },
        position: {
            corner: {
                target: 'bottomLeft',
                tooltip: 'right'
            }
         },
         style: {
             name: 'light',
             width: 700
         }
    });
});

Which I love wen the .tooltip item is on the right panel of my website, but if not can't see it complete,

How can I make it tooltip:'right' when it's somewhere else? I mean, how can I know?

The solution in my similar to yours case was:

position : {
    adjust : {
        screen : true
    }
}
