Questions about Spark DataGrid (Header Font Styles, Header Gradient)

Question

Just starting out in 4.5 SDK, and just a tad confused on the Spark DataGrid.
1) Trying to set the font style for just the header, but don't see those properties in the designer....as they appear to apply to every part of the DataGrid.
2) Want to set a linear gradient for the header utilizing two specific colors, alphas and ratios.  Not sure where to set them now.
I think that is it for now.  From what I have done with it so far, I love it....just obviously not as much user documentation as the MX DataGrid.
Thanks in advance!

Answer 1

You can do per column header renderers by setting the headerRenderer property on the column. But if you want to swap out all the headers, the header renderer has to be specified in the skin. One neat trick you can do is subclass the DataGridSkin and replace the "headerRenderer" declaration. This also works with the other skin parts.
<?xml version="1.0" encoding="utf-8"?>
<skins:DataGridSkin xmlns:fx="http://ns.adobe.com/mxml/2009"
                xmlns:s="library://ns.adobe.com/flex/spark"
                xmlns:mx="library://ns.adobe.com/flex/mx"
                xmlns:skins="spark.skins.spark.*">
    <fx:Declarations>
        <!-- See DataGridSkin for other possible parts -->    
        <fx:Component id="headerRenderer">
            <s:CustomGridHeaderRenderer />
        </fx:Component>
    </fx:Declarations>
</skins:DataGridSkin>
