Re: [flexcoders] Re: Alternating colors for AdvancedDataGrid

[Everson Alves]

Hello,  I found a solution extending ADG. I'll post here if anyone need it
too.

Just override drawRowBackgrounds and use alternatingItemColors properties.

CODE:
override protected function drawRowBackgrounds():void
  {

  var rowBGs:Sprite = Sprite(listContent.getChildByName("rowBGs"));
  if (!rowBGs)
  {
  rowBGs = new FlexSprite();
  rowBGs.mouseEnabled = false;
  rowBGs.name = "rowBGs";
  listContent.addChildAt(rowBGs, 0);
  }

  var color:Object;
  var depthColors:Boolean = false;

  var colors:Array = getStyle("alternatingItemColors");

  color = getStyle("backgroundColor");
  if (!colors || colors.length == 0)
  return;

  StyleManager.getColorNames(colors);

  var curRow:int = 0;

  var i:int = 0;
  var actualRow:int = verticalScrollPosition;
  var n:int = listItems.length;

  var alternateRoot:int = verticalScrollPosition;

  while (curRow < n)
  {
  if (listItems[curRow][0])
  {
  var d:int = getDepth(listItems[curRow][0].data);
  if(d == 1){
  alternateRoot++;
  }
  drawRowBackground(rowBGs, i++, rowInfo[curRow].y, rowInfo[curRow].height,
colors[alternateRoot % colors.length], actualRow);
  }
  else
  {
  drawRowBackground(rowBGs, i++, rowInfo[curRow].y, rowInfo[curRow].height,
uint(color), curRow);
  }
  curRow++;
  actualRow++;
  }

  while (rowBGs.numChildren > i)
  {
  rowBGs.removeChildAt(rowBGs.numChildren - 1);
  }
  }
