    id:'tab-win',
    init : function(){
        this.launcher = {
            text: 'tab exemple',
            iconCls:'accordion',
            handler : this.createWindow,
            scope: this
        }
    },

    createWindow : function(){
        var desktop = this.app.getDesktop();
        var win = desktop.getWindow('tab-win');
        if(!win){
            win = desktop.createWindow({
                id: 'tab-win',
                title:'Tab Window',
                width:740,
                height:480,
                iconCls: 'tabs',
                shim:false,
                animCollapse:false,
                border:false,
                constrainHeader:true,

                layout: 'fit',
                items:
                    new Ext.TabPanel({
                        activeTab:0,

                        items: [{
                            title: 'Tab Text 1',
                            header:false,
                            html : '<p>Something useful would be in here.</p>',
                            border:false
                        },{
                            title: 'Tab Text 2',
                            header:false,
                            html : '<iframe id="sampleframe" name="sampleframe" width="90%" height="400px" frameborder="2" src="../package/canvas/canvas.html" style="border: 0px solid #cecece;"></iframe>',
                            border:false

OK RESOLVED

we should add a new declaration for the new item ("TabWindows()") like that :

getModules : function(){
		return [
			new MyDesktop.GridWindow(),
            new MyDesktop.TabWindow(),
			new MyDesktop.TabWindows(),
            new MyDesktop.AccordionWindow(),
            new MyDesktop.BogusMenuModule(),
            new MyDesktop.BogusModule()
		];
	},
