How to create a displayfield in Sencha Touch

Sencha Touch has, unlike Ext JS,  no displayfield component. That is somewhat unhandy, when you are used to it. But searching on the forum of Sencha I found a satisfying solution to solve this. Thanks to the effort of Sencha user Mike Suiter from Omaha I have put the following class definitions in my applications.


Ext.define('Ext.ux.DisplayField', {
    extend: 'Ext.field.Field',
    xtype: 'displayField',
    requires: ['Ext.ux.DisplayFieldComponent'],
    config: {
        component: {
            xtype: 'displayFieldComponent'
    setValue: function(value) {
        return this;


Ext.define('Ext.ux.DisplayFieldComponent', {
    extend: 'Ext.Component',
    xtype: 'displayFieldComponent',
    config: {
        cls: 'x-field-input'
    getTemplate: function() {
        return [
                reference: 'displayElement',
                tag: 'div',
                style: 'padding:10px'}

How to put this in your application

In my applications root folder (apps) I have a folder called ux. In this folder I have placed all my third party components and plugins. So my app folder has a structure as shown below. It contains 2 applications: Someapp and Anotherapp. It can even be that one app is an Ext JS app and the other a Sencha Touch app.

  • apps
  • Someapp
  • controller
  • view
  • panel
  • somepanel
  • dataview
  • some files
  • model
  • somemodel.js
  • store
  • somestore.js
  • Anotherapp
  • this apps structure...
  • ux
  • Ext.ux.DisplayField
  • Extus.Display.FieldComponent

Put the 2 components DisplayField and DisplayFieldComponent in the root of the ux folder. Now put the following in your app.js.

    enabled: true,
    disableCaching: false,
    paths: {
        Someapp: 'Apps/Someapp',
        Anotherapp: 'Apps/Anotherapp',
        'Ext.ux': 'Apps/ux'

  ... more requirements ...

(line 6): Only put here the other app if you would like to share classes from that other project. If I build an Ext JS application and a tablet version using the same models and stores f.e. then I don't define them twice. Another useful usage is that in this way you can share base classes that you use in every project. So the other app can also be a library of your most used classes for every project.

How to use it

The usage is very simple and not different to the usage of a text field. It is in fact an extension of the Ext.field.Field class.

  xtype: 'displayField',
  label: 'Nice label',
  itemId: 'somefield'
  value: 'some initial data'

You can change the content of the field by using the setValue method.

panel.down('#somefield').setValue('Some other data');

Don't forget that somefield is the itemId of that field. Below you see a sample of usage on an iPhone in a Ext.sheet component.
