Sencha: set image as background to a panel

Question

I want to set a background image in sencha to a panel:

EDIT

Ext.define('components.NewPanel', {
extend: 'Ext.Panel',
style: {
    background:'#ffffff',
    backgroundImage: 'url(icon.PNG)',
    backgroundSize: '10% 85%',
    backgroundRepeat: 'no-repeat',
    backgroundPosition: 'bottom left',
},

initialize: function () {

    var newIcon=Ext.create('Ext.Img', {
        src: "image1.png",
        cls: "img",
        scope: this,
        listeners: {
                    tap: {
                        fn :function (img, evt) {
                            Ext.Msg.alert("This is a test");
                        },// function
                    }// tap
        }//listeners
    });//create
    this.add([newIcon]);
},
config: {
    layout: {
        type: 'fit'
    }
}

});

But nothing is displayed. What to do? any help is appreciated.

Solution 1

You can do as bellow

   Ext.define('MyApp.view.WelcomePanel', {
    extend: 'Ext.form.Panel',
    alias: 'widget.WelcomePanel',

    config: {
        style:"background-color:white;",
        itemId:'WelcomePanel',
        fullscreen:true,
        layout: 'card',
        html:'<div align="center" style="background-color:white;" ><img src="http://src.sencha.io/http://yoursite.com/splash.png" ></div>',
        items: [
                {xtype:'MainPanel', docked:'top'},

        ]
    }

});

Solution 2

I had to set the background of the panel body to transparent, because otherwise that white background prevented my image from showing. Try adding this:

bodyStyle: 'background: transparent;',

Solution 3

Use bodyStyle config

Ext.create('Ext.panel.Panel', {
        border: false,
        bodyStyle: {
        'background': 'url(wall.jpg) !important'
         }
        //another config
        ....
    })
