change tab with a button

You must Login before you can answer or comment on any questions.

Hello people,

Platform: iOS

I have in my app one tabbar:

var win1 = Titanium.UI.createWindow({  
    url:'home.js',
    titleid:'XY',
    barColor: '#0B72B5'
});
var tab1 = Titanium.UI.createTab({  
    icon: 'YX',
    title:'XY',
    window:win1
});
var win2 = Titanium.UI.createWindow({  
    url:'inhalt.js',
    titleid:'XY',
    barColor: '#0B72B5'
});
var tab2 = Titanium.UI.createTab({  
    icon: 'YX',
    title:'XY',
    window:win2
});
tabGroup.addTab(tab1);  
tabGroup.addTab(tab2);  
 
tabGroup.open();
Is it possible when a tab is opened, a button on the side of the tabbar to create responsive and you can navigate by clicking the button in the tabs?

With best regards

  • no, the problem is - that the tabgroup defined in app.js - but the content is in home.js. i need a connection to the var of app.js to change it.

    thanks for answer!

  • ok, so you need to acces tabGroup from win1, is that correct? In that case, you can pass tabGroup itself as an argument of win1, so it will be available in home.js

    app.js:

    var tabGroup = Ti.UI.createTabGroup();
 
var win1 = Titanium.UI.createWindow({  
    url:'home.js',
    titleid:'XY',
    barColor: '#0B72B5',
    tabGroup: tabGroup
});
    then, in home.js 
    var win = Ti.UI.currentWindow;
 
var tabGroup = win.tabGroup;
 
//then use in your button event listener, like
 
btn.addEventListener('click', function(){
 //set the active tab by its index number
    tabGroup.setActiveTab(tabIndex); 
});
    Just note that using multiple execution context is considered a bad practice, I suggest you to move your code to commonJS.
