  You have to append close button on the opened window.
  mapWin.setLeftNavButton(closeBtn);
  

  Also, you have to use tab object to launch tab, and i believe, i could be wrong, the title only shown on tabbed window.

  var tabGroup = Titanium.UI.createTabGroup();
  var Tab1 = Titanium.UI.createTab({window:rootWin,title:"Root Windows"});
  tabGroup.addTab(Tab1);
  tabGroup.open();
  

• Thanks for writing Daniel,

  I guess this is getting to the "root" of my question. Does the parent have to be a tabGroup? I would like to avoid tabs if possible. I can create a parent that is a window object, but it's children do not get the the navbar, I /believe/ that leftNavButton is only available when the window is the child of a tab.

  I tried with the first chunk of code and it fails for me, in fact the window doesn't even load.

  Whoops, looks like you meant:

  mapWin.LeftNavButton(closeBtn);
  

• There's many samples in KitchenSink you can refer to.

  You can hide tab with window.hideTabBar();
