Sencha Touch v2 toolbar title alingment - sencha-touch

Question

When I create a toolbar like below the title is misplaced to the right of the last button, any ideas how to fix it?
{
xtype: 'toolbar',
docked: 'top',
title: 'Chat',
items: [{
xtype: 'button',
text: 'Places',
ui: 'back',
id: 'backToPlaces'
},
{
xtype: 'spacer'
},
{
xtype: 'button',
text: 'People',
ui: 'forward',
id: 'toProfiles'
}

Answer 1

I was also fighting with the toolbar. Then I discovered the navigationbar.
The title is in the center. With a button aligned left and right. (see align property)
{
docked: 'top',
xtype: 'navigationbar',
title: 'Chat',
items: [
{
xtype: 'button',
ui: 'back',
action: 'back',
text:'BACK',
itemId: 'backButton'
},
{
xtype: 'button',
ui: 'decline',
action: 'cancel',
text:'Cancel',
itemId: 'cancelButton',
align : 'right'
}
]
}

Answer 2

just after answered this, i found the "centered" attribute and looked at creation of title element of sencha, so just forget this above and use in your config:
var myToolbar = new Ext.Toolbar({
docked : 'top',
title: {
title: 'my Title',
centered: true
},
items : []
});

Answer 3

In Sencha 2 there is no "special" title element, it is created as simple element in the "items". So i future, you can just add it at right place direcly by placing the config to your docked bar:
var myToolbar = new Ext.Toolbar({
docked : 'top',
items : [{
xtype: 'spacer',
},{
xtype: 'title',
title : 'Hello World'
},{
xtype: 'spacer',
}]
});
Only with spacer it is in the middle.

Answer 4

It is clearly stated in the docs that NavigationBar is a private class for internal use by the framework http://docs.sencha.com/touch/2-0/#!/api/Ext.navigation.Bar and the centered attribute metioned by anj does not work as expected (at least in the latest release).
According to this post http://www.sencha.com/forum/showthread.php?161082-PR3-Toolbar-title-position-broken-when-spacers-control-button-positioning&p=691928 it is simply a bug that the title is not centered and we should wait for next release. In the meantime you might use navigationbar if you need to.

Answer 5

If you want to leverage something similar to how titles in Toolbar behaves of Ext.navigation.Bar. see the Ext.TitleBar http://docs.sencha.com/touch/2-0/#!/api/Ext.TitleBar
This class handles things like long titles for you by automatically adding ellipses and the title is always centered horizontally.

Answer 6

There is no longer a NavigationBar component which is public. It is simply used internally by NavigationView. You should never use this.
Instead, you should use Ext.TitleBar. This allows you to center the title config and also use the align property on items (normally buttons) to align them to the left or right.
It also has built in support when the title is too long, or any items are too wide. It will automatically limit the length of all items to a certain width, and add ellipse to the title if needed.
Here is a simple example:
var titleBar = Ext.create('Ext.TitleBar', {
docked: 'top',
title: 'Navigation',
items: [
{
iconCls: 'add',
iconMask: true,
align: 'left'
},
{
iconCls: 'home',
iconMask: true,
align: 'right'
}
]
});
Ext.Viewport.add(titleBar);
