Is there a way to minimize ext.window?

Code:
function window1(){
     Ext.state.Manager.setProvider(new Ext.state.CookieProvider());
     win1 = new Ext.Window({
         width:100,
         height:100,
         title:"1",
         id: "win1",
         closable: true,
         x: 150,
         y:10
      });   
      
      win1.show();
        
}
tnx,
