ExtJS的隱藏colorfield

Question

阿爾法酒吧和文字我使用this從colorfield選擇挑選顏色。但是，我不希望alpha欄可用和可見。我如何從我的概述中隱藏這個？這似乎是一個簡單的問題，但我真的不知道答案。

如果重寫類，或將其延伸到自己的組件和改變構造函數如下：

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); 
},
