javascript - EXTJS 5 树网格自定义行 css

Question

我有一个树形网格，我想更改父行和子行的 css(在我的例子中是背景颜色)。我做了一些 css 类并使用了 viewConfig.getRowClass 方法，但它不适用于悬停和选择。

这是我的问题的 fiddle :https://fiddle.sencha.com/#fiddle/jl1

这是我的树状网格:

var tree = Ext.create('Ext.tree.Panel', {
    renderTo: Ext.getBody(),
    title: 'TreeGrid',
    rootVisible: false,
    width: 300,
    height: 250,
    store: store,

    viewConfig: {
        getRowClass: function(record, index) {
            if (record.get('name').indexOf('Group') != -1) {
                return 'row-parent';
            }
            return 'row-child';
        }
    },

    columns: [{
        xtype: 'treecolumn',
        text: 'Name',
        dataIndex: 'name',
        width: 150
    }, {
        text: 'Description',
        dataIndex: 'description',        
        width: 150
    }]
});

这是我的 CSS:

.row-parent .x-grid-cell {    
    background-color: #c1ddf1 !important;
}
.row-parent .x-grid-row-over .x-grid-cell {
    background-color: #3da5f5 !important;
}
.row-parent .x-grid-row-selected .x-grid-cell {
    background-color: #ff0 !important;
}

.row-child .x-grid-cell {
    background-color: #e2eff8 !important;
}
.row-child .x-grid-row-over .x-grid-cell {
    background-color: #85c4f5 !important;
}
.row-child .x-grid-row-selected .x-grid-cell {
    background-color: #ff0 !important;
}

你知道为什么选择和悬停 css 不起作用吗？

提前致谢 =) !
