该物业仍具有validateProperties旧值

问题描述

我有一个自定义渲染器（继承自 AdvancedDataGridItemRenderer ），而且我重写 validateProperties 和使用的价值在宽度属性，但我每次都让旧值！是不是 validateProperties 应该执行性能提交之后，（我打电话超）？这是我的code：

I have a custom renderer (inherits from AdvancedDataGridItemRenderer), and I'm overriding validateProperties and using the value of the width property, but I'm getting the old value every time! Isn't validateProperties supposed to execute after the properties were committed (I'm calling super)? Here's my code:

public override function validateProperties():void
{
    super.validateProperties();
    if ((AdvancedDataGrid(listData.owner).columns[listData.columnIndex].
            showDataTips)&&(textWidth>width))
        toolTip=listData.label;
    else toolTip=null;
}

谢谢！

推荐答案

我解决了它。诀窍是使用 validateSize 为宽度属性。 validateProperties 对于那些不属于任何其他团体对此有一个专门的 validateX 功能特性（如为 validateSize ， validateList ，等等）。

I solved it. The trick is to use validateSize for the width property. validateProperties is for properties that don't belong to any of the other groups for which there's a dedicated validateX function (such as validateSize, validateList, etc.).
