Sencha touch :: how to create a panel for previewing a website inside iFrame

I need to allow some website previews inside sencha. I see two different possibilities:

  • opening a SafariMobile app to display a link
  • creating a panel with an iFrame inside the html property.

because I don’t know how to reach 1. I started with 2. but ran into some troubles:

a) the contents of my iFrameis are not scrolling. if I try to scroll through the contents, the entire viewport scrolls, including my buttons at the bottom-tabPanel!

b) the displayed website loads without any css or images

here is my previewPanel code:

app.views.WebsitePreview = Ext.extend(Ext.Panel, {
    layout: 'card',
    scroll: 'vertical',
    styleHtmlContent: true,
    fullscreen: true,

    initComponent: function(){      
        this.html = '<iframe width="100%" height="100%" src="'+ this.theLink + '"></iframe>',
        var toolbarBase = {
            xtype: 'toolbar',
            title: 'Vorschau ' //+ this.childData.childUsername,
        };


        if (this.prevCard !== undefined) {
                toolbarBase.items = [
                {
                    xtype: 'button',
                        ui: 'back',
                    text: 'zurück', //this.prevCard.title,
                    scope: this,
                    handler: function(){
                        this.baseScope.setActiveItem(this.prevCard, { type: 'slide', reverse: true });
                    }
                }
            ]
       };

        this.dockedItems = toolbarBase;
        app.views.WebsitePreview.superclass.initComponent.call(this);
    }
});

Ext.reg('websitepreview', app.views.WebsitePreview);

thnx for your help!
