Flex DataGrid 列宽

发布于 2024-08-02 12:44:58 字数 478 浏览 3 评论 0原文

在我的 Flex 应用程序中，我将列的宽度和可见性存储在 xml 文件中。当应用程序加载时，它从 xml 文件中读取并将列值设置为适用：

for(i = 0; i < columnsOrder.length; i++){
    newOrder[i] = myDG.columns[Number(columnsOrder[i]) - 1];
    newOrder[i].visible = (Number(columnsVisiblity[i]) == 1);
    newOrder[i].width = Number(columnsWidth[i]);
}
myDG.columns = newOrder;
myDG.invalidateList();

问题似乎是设置可见性（它正确设置了可见字段，但弄乱了宽度）...我尝试在设置后设置它宽度（循环外部）以及循环之前的宽度。如果我不对可见性做任何事情，它会正确调整列的大小。

有什么想法吗？

In my flex app I store the widths and visiblility of columns in an xml file. When the app loads it reads from the xml file and sets he columns values as applicable:

for(i = 0; i < columnsOrder.length; i++){
    newOrder[i] = myDG.columns[Number(columnsOrder[i]) - 1];
    newOrder[i].visible = (Number(columnsVisiblity[i]) == 1);
    newOrder[i].width = Number(columnsWidth[i]);
}
myDG.columns = newOrder;
myDG.invalidateList();

The problem appears to be setting the visibility (it sets the visible field correctly but messes up the width)... I've tried setting it after setting the width (outside of the loop) and before the loop as well. It resizes the columns properly if I don't do anything with the visibility.

Any ideas?

在类文件顶部添加导入语句：

import mx.core.mx_internal;

然后使用 mx_internal 命名空间删除，删除列的所有者，更改宽度，然后重新分配父级：

public static function resizeColumn(col:DataGridColumn, size:int):void
    {
        var owner:* = col.mx_internal::owner
        col.mx_internal::owner = null;

        col.width = size;

        col.mx_internal::owner = owner;
    }

这应该可以解决问题（好吧，在咒骂几天后，它为我们做到了）

Add an import statement at the top of your class file:

import mx.core.mx_internal;

Then remove using the mx_internal namespace, remove the owner of the column, change the width and then reasign the parent:

public static function resizeColumn(col:DataGridColumn, size:int):void
    {
        var owner:* = col.mx_internal::owner
        col.mx_internal::owner = null;

        col.width = size;

        col.mx_internal::owner = owner;
    }

This ought to do the trick (well, it did for us after a couple of days of swearing)
