Open window within a window to retain top navbar

No matter what I try, I can't preserve the top navbar so users can go back. I'm new to windows and modal and can't get it to not load over the entire page and navbar.

// create main day window
        var dayWindow = Titanium.UI.createWindow({
            id: 'win1',
            title: 'Schedule',
            backgroundColor: '#fff',
            barColor: '#414444',
            fullscreen: false
        });
 
       var webview = Titanium.UI.createWebView({url:'http://www.appcelerator.com'}); 
       var window = Titanium.UI.createWindow(); 
       window.add(webview); 
       window.open({modal:true});
 
        return dayWindow;

you need to either use a navigationController OR open the windows using a tabGroup to get the effect you are looking for.

When you use "modal" it will create a completely new navigation bar and you will have to create your own left and right buttons to take the appropriate action

//in app.js

// this sets the background color of the master UIView (when there are no windows/tab groups on it)

Titanium.UI.setBackgroundColor('#000'); // create tab group

var tabGroup = Titanium.UI.createTabGroup(); // // create base UI tab and root window //

var win1 = Titanium.UI.createWindow({

title:'app.js',

backgroundColor:'#fff'

});

var tab1 = Titanium.UI.createTab({

icon:'KS_nav_views.png',

title:'Tab',

window:win1

});

var button= Ti.UI.createButton({ title:'open new window' })

button.addEventListener('click',function(){

var win= Ti.UI.createWindow({

    title:'new window',
    url:'new.js'
})
 tab1.open(win);

})

win1.add(button);

tabGroup.addTab(tab1);

// open tab group tabGroup.open();

//create a fiel named new.js and in new.js

var wind= Ti.UI.currentWindow;

Window was being created over the existing one. I changed it to simply load into the current window.

var win = Titanium.UI.currentWindow;
