我找不到配置按钮 "Cerrar" 侦听器以转到 class 方法的方法 "Cerrar"。

我尝试了所有的范围,但没有成功。

有人可以帮我吗?

我一直在研究这段代码,并设法让按钮点击处理程序使用下面的侦听器代码调用正确的函数,但感觉不太对,通常你可以确定按钮的范围 this 传递父组件的范围,但它似乎对我不起作用。

我会继续研究范围方法,但与此同时,您应该可以使用以下两种方法之一:

// method 1
xtype: 'button',
...
listeners: {
    click: function() { this.up('panel').Cerrar(); }
}

// method 2
xtype: 'button',
...
listeners: {
    click: function() { this.ownerCt.ownerCt.Cerrar(); }
}
