• I could make app to show/hide toolbar using createToolBar and visible setting below.

  // create button for show toolbar
  var showtoolbar = Titanium.UI.createButton({
  title:'show toolbar',
  width:200,
  height:40,
  top:80
  });

  // create toolbar
  var toolbar1 = Titanium.UI.createToolbar({
  items:[left,flexSpace, flexSpace,backbtn,flexSpace, flexSpace,right],
  bottom:0,
  borderTop:true,
  borderBottom:false,
  opacity:0.5,
  barColor:'#000',
  visible:false
  });
  win3.add(toolbar1);

  // create hidetoolbar
  var hidetoolbar = Titanium.UI.createButton({
  title:'Hide Toolbar',
  width:200,
  height:40,
  top:150
  });

  // event listener for hidetoolbar button
  hidetoolbar.addEventListener('click', function()
  {
  toolbar1.visible = false;
  });
  win3.add(hidetoolbar);

  var hidden=false;

  // event listener for showtoolbar button
  showtoolbar.addEventListener('click', function()
  {
  if (!hidden)
  {
  win3.hideNavBar();
  hidden = true;
  }
  else
  {
  win3.showNavBar();
  hidden = false;
  }

  toolbar1.visible = true;
  

  });
  win3.add(showtoolbar);
  win3.showNavBar();

  But I would like to use setToolbar(). How can I use it?
  Please advise me.

• After I created new window(w/o tab) and I tried Kitchen Sink source below from Window_toolbar.js.

  //
  // SINGLE BUTTON ON LEFT
  //
  var b1 = Titanium.UI.createButton({
  title:'One Button - Left',
  width:200,
  height:40,
  top:10
  });
  b1.addEventListener('click', function()
  {
  var b = Titanium.UI.createButton({
  title:'Button',
  style:Titanium.UI.iPhone.SystemButtonStyle.BORDERED,
  enabled:false
  });
  b.enabled = false;
  win.setToolbar([b]);
  });
  win.add(b1);

  But this did not show toolbar.
  Why does this happen?
  Do I need to have tab group like Kitchen Sink?

  So I have to use createToolBar. It showed toolbar. But I don't know how to disable this toolbar.
  How can I disable this toolbar?

  Please advise me.

• to hide the toolbar try something like Ti.currentWindow.setToolbar(null,[animated;TRUE});
