Overiding Maximize method

Hi all

On the navigation bar of an iView, there is functions to maximize, minimize, refresh, personalize etc. How can I overide the maximize method. I assume it should be similar to the refresh method:

protected void doRefresh(

IPortalComponentRequest arg0,

IPortalComponentResponse arg1) {

super.doRefresh(arg0, arg1);

}

What can I do to overide maximize method?

Thanx in advance
