Flex 3 DataGrid列宽问题 [英] Flex 3 DataGrid Column Width Problem

问题描述

我正在拉xml数据以确定哪些列是可见的，每列的宽度。我的datagrid的宽度可以改变它在HDividedBox的一边。可见性部分起作用，但设置宽度会导致头痛。代码：

  for（循环通过从XML中检索列数据）
 {
 newData [i ] = dg.columns [Number（columnsOrder [i]） -  1]; 
 newData [i] .visible =（Number（columnsVisibility [i]）== 1）; 
 newData [i] .width = Number（columnsWidth [i]）; 
 trace（newData [i] .headerText +w：+ newData [i] .width.toString（）+v：+ newData [i] .visible.toString（））; 
} 
 dg.columns = newData; 
 dg.invalidateList（）; 
  

在跟踪中，前两个项目的宽度是正确的，但是它显示为20 连续一个...

 日期w：240 v：true 
标题w：184 v：true 
请求者w：20 v：true 
批准者w：20 v：true 
类别w：20 v：false 
状态w：20 v：false 
优先级w：20 v：false 
  

当我输出Number（columnsWidth [i]）时，它显示为正确的值，所以在宽度的分配中发生了奇怪的事情。

现在已经看了几个小时，并尝试了多个事情来尝试修复它没有用。

解决方案

我的数据网格的宽度可以改变它的一个HDividedBox的一面。

那就是问题。

当DataGrid的宽度不固定时，我面对与Flex 2和Flex 3 DataGridColumn宽度完全相同的问题。我唯一的解决方法是修复DataGrid的宽度或切换到AdvancedDataGrid或其他类似的组件。

I'm pulling xml data to determine which columns are visible, and the widths of each column. My datagrid's width can change sinces its on one side of a HDividedBox. The visibility part works, but setting the width is causing headaches. Heres the code:

for(loop through column data retrieve from XML)
{ 
    newData[i] = dg.columns[Number(columnsOrder[i]) - 1];
    newData[i].visible = (Number(columnsVisibility[i]) == 1);
    newData[i].width = Number(columnsWidth[i]);
    trace(newData[i].headerText + " w:" + newData[i].width.toString() + " v:" + newData[i].visible.toString());
}
dg.columns = newData;
dg.invalidateList();

In the trace the width is correct for the first two items, however, its showing up as "20" for ever consecutive one...

Date w:240 v:true
Title w:184 v:true
Requestor w:20 v:true
Approved By w:20 v:true
Category w:20 v:false
Status w:20 v:false
Priority w:20 v:false

When I output Number(columnsWidth[i]) it shows up as the correct value so something weird is happening in the assignment of the width.

Been looking at this for a few hours now, and have tried multiple things to try to fix it to no avail.

解决方案

My datagrid's width can change sinces its on one side of a HDividedBox.

That's the problem right there.

I faced the exact same problem with Flex 2 and Flex 3 DataGridColumn width's whenever the width for the DataGrid was not fixed. The only solution I had was to fix the width of the DataGrid or switch to AdvancedDataGrid or other similar components.
