Question

在互联网上搜索后，我无法理解我的代码中的诀窍。我要做的是将一个表单面板放在一个按钮内。看起来很简单，但基本上不知道我错过了什么。我使用ext js 3.4。我在这里找到了这个很酷的代码：http://jsfiddle.net/ErnestoRR/bYMP5/。这基本上是我需要的，但它在ext js 4.0中。在这里，我发给你的是：

因为没有人回答我，我自己回答=）这是解决方案：

Ext.onReady(function() {

PanelMain = Ext.extend(Ext.Panel, {
    height: 300,
    width: 500,
    title: 'My Panel',

    initComponent: function() {
        Ext.applyIf(this, {

            tbar: {
                xtype: 'toolbar',
                items: [
                {
                    xtype: 'button',
                    text: 'Impresora',
                    menu: {
                        xtype: 'menu',
                        items: [{
                            xtype: 'container',
                            items: [{
                                xtype: 'form',
                                bodyPadding: 5,
                                items: [{
                                    xtype: 'textfield',
                                    fieldLabel: 'Titulo'
                                }, {
                                    xtype: 'textfield',
                                    fieldLabel: 'Comentario'
                                }, {
                                    xtype: 'combo',
                                    fieldLabel: 'Resolucion'

                                }, {
                                    xtype: 'button',
                                    text: 'boton'
                                }]
                            }]
                        }]
                    }
                }]
            }


        });

        PanelMain.superclass.initComponent.call(this);
    }

});

Ext.reg( 'panelmain', PanelMain ); // register xtype

var panel = new PanelMain({
    renderTo: Ext.getBody()
});

});
