Flex DataGrid 删除标题鼠标悬停突出显示 [英] Flex DataGrid Remove Header MouseOver Highlighting

问题描述

我想删除鼠标悬停在 DataGrid 标题上时出现的突出显示.

I want to remove the highlight that occurs when mouse over occurs on the headers of a DataGrid.

推荐答案

也许以下 hack 会对某人有所帮助.我只是想从数据网格标题 (flex 3) 中删除翻转和选择.

Maybe the following hack will help someone. I simply wanted to remove the rollover and selection from datagrid header (flex 3).

我做了什么:

1) 创建一个新的 DataGridHeader 子类并覆盖 drawHeaderIndicator 和 drawSelectionIndicator

1) Create a new subclass of DataGridHeader and override drawHeaderIndicator and drawSelectionIndicator

package
{
 import flash.display.Sprite;

 import mx.controls.dataGridClasses.DataGridHeader;
 import mx.controls.listClasses.IListItemRenderer;

 public class MyDataGridHeader extends DataGridHeader
 {
  public function MyDataGridHeader()
  {
   super();
  }

  override protected function drawHeaderIndicator(indicator:Sprite, x:Number, y:Number, width:Number, height:Number, color:uint, itemRenderer:IListItemRenderer):void
  {

  }

  override protected function drawSelectionIndicator(indicator:Sprite, x:Number, y:Number, width:Number, height:Number, color:uint, itemRenderer:IListItemRenderer):void
  {

  }
 }
}

2) 创建 DataGrid 的一个新子类 - 假设 MyDataGrid 并在构造函数中执行以下操作:

2) Create a new subclass of DataGrid - lets say MyDataGrid and in constructor do the following:

public function MyDataGrid()
  {
   super();
   this.mx_internal::headerClass = MyDataGridHeader;
   ....
  }

这将强制 DataGrid 使用您的 DataGridHeader.

This will force DataGrid to use your DataGridHeader.
