javascript - Extjs 在色域中隐藏 alpha 条和文本

Question

我正在使用this从色域选择器中选取颜色。但是我不希望阿尔法栏可用且可见。如何在我的概览中隐藏这一点？这似乎是一个简单的问题，但我真的不知道答案。

如果您重写该类，或将其扩展到您自己的组件中并将构造函数更改为以下内容:

constructor: function (config) {
    var me             = this,
        childViewModel = Ext.Factory.viewModel('colorpick-selectormodel');

    // Since this component needs to present its value as a thing to which users can
    // bind, we create an internal VM for our purposes.
    me.childViewModel = childViewModel;
    me.items = [
        me.getMapAndHexRGBFields(childViewModel),
        me.getSliderAndHField(childViewModel),
        me.getSliderAndSField(childViewModel),
        me.getSliderAndVField(childViewModel),
        /* remove this one as it is the alpha field */
        //me.getSliderAndAField(childViewModel),
        me.getPreviewAndButtons(childViewModel, config)
    ];

    me.callParent(arguments);
},
