Sencha Touch Horizontally Center Search Field in Navigation Bar - html

Question

This question is pretty downright dumb and I might have stumbled upon a bug but I need to center my searchfield in my navigation bar in Sencha Touch and I just can't make it work. This is my code:
Ext.define('Myapp.view.MyNav', {
extend: 'Ext.navigation.View',
xtype: 'mynav',
requires: [
'Ext.field.Search', 'Ext.Button'
],
config: {
fullscreen: true,
navigationBar: {
items: [
{
xtype: 'searchfield',
placeHolder: 'Search...',
listeners: {
keyup: function(field) {
}
},
align: 'right'
}
]
},
items: [
{
title: 'MyNav',
xtype: 'list',
fullscreen: true,
grouped: true,
store: {
fields: ['name', 'html'],
sorters: 'name',
data: [
{name: 'Alfa', html: '<p>alfa</p>'},
{name: 'Beta', html: '<p>beta</p>'},
{name: 'Gamma', html: '<p>gamma</p>'},
{name: 'Mupp', html: '<p>mupp</p>'},
{name: 'Tupp', html: '<p>tupp</p>'}
],
grouper: {
groupFn: function(record) {
return record.get('name')[0];
},
indexBar: true
},
},
listeners: {
select: function(view, record) {
var test = Ext.create('Ext.Panel', { fullscreen: true,
title: record.get('name'),
layout: {
type:'vbox'
},
items: [
{
xtype: 'panel',
html: record.get('html')
}
]
});
var mainnav = Ext.ComponentQuery.query('bookmarksmainnav')[0];
mainnav.setActiveItem(test);
}
},
itemTpl: '{name}'
}
]
}
});
Focus on the actual navigation bar thing, the other stuff is just code pasted (and I modified it somewhat), I'm pretty sure this is a bug though.
Thanks in advance!

Answer 1

you can try using a toolbar docked in the bottom of the page with the search field centered, I don't know why but the navigation bar ignores the centered property.
Something like this:
config: {
fullscreen: true,
navigationBar: {
},
items: [
{
xtype: 'toolbar',
docked: 'bottom',
items: [
{
xtype: 'searchfield',
placeHolder: 'Search...',
listeners: {
keyup: function(field) {
}
},
centered: true
}
],
},
{
title: 'MyNav',
xtype: 'list',
If you need the search field on the top of the screen you could try hiding the navigation bar with hidden: true and changing the docked property in the toolbar.
Hope it helps!

Answer 2

A better answer (for me) that just centres whatever you have added to the navigation bar, is:
this.getNavigationBar().leftBox.setCentered(true);
You will probably want to manage the centred-ness of the navigation bar for each page, though.

Answer 3

I used
layout: {
align: 'center',
pack: 'center',
type: 'hbox'
}
This would be just under the docked: 'bottom', line is the example above.

Answer 4

Whenever I find it difficult to center a desired field, I just add a spacer before and after, combined with a flex for the item I want to center, it never fails. In this case:
items: [
{
xtype: 'spacer',
},
{
xtype: 'searchfield',
placeHolder: 'Search...',
listeners: {
keyup: function(field) {
}
flex: 0.7
},
{
xtype: 'spacer',
},
