Hi Tracy,
This is an interesting idea...but you have me at a bit of a
loss....I was already heading down part of the same path you laid out
here...here is my renderer code thus far:
First, the column from my ADG:
<mx:AdvancedDataGridColumn id="groupedHVR1" dataField="Hvr1M"
headerText="HVR1 Mutations" headerWordWrap="true" textAlign="left"
wordWrap="true" editable="false" width="100" showDataTips="true"
itemRenderer="renderers.GeneralRenderers.AminoAcidRenderer" />
now the AminoAcidRenderer.mxml:
<?xml version="1.0" encoding="utf-8"?>
<mx:Label xmlns:mx="http://www.adobe.com/2006/mxml";
implements="mx.core.IFactory" truncateToFit="true"
width="100%" height="100%" paddingLeft="2" paddingRight="2">
<mx:Script>
<![CDATA[
import mx.utils.ObjectProxy;
override public function set text(value:String):void
{
if (value != null && value != " " && value != "")
{
value = String(value.replace("G",'<font
color="black">G</font>'));
value = String(value.replace("A",'<font
color="green">A</font>'));
value = String(value.replace("T",'<font
color="red">T</font>'));
value = String(value.replace("C",'<font
color="blue">C</font>'));
super.htmlText = value;
}
else
{
super.htmlText = value;
}
}
public function newInstance():*
{
return new AminoAcidRenderer();
}
]]>
</mx:Script>
</mx:Label>
But, alas, there are a couple of problems here. First, the
string.replace() only affects the first occurrence of the pattern and
not every occurrence (I wonder if a regex would remedy that?). Then
although the substitution gets done for those patterns that are found,
the htmlText isn't getting rendered...and I wonder if it's due to the
function set text instead of function set htmlText, which I tried and
literally got nothing.
I've also looked at the TextRange that someone else suggested but
not sure how to possibly use that as it needs a begin/end index and the
letters are sporadic from one string to the next.
How would I setup the labelFunction to parse the string to get the
letters?
Thanks in advance!

I suggest that you use a labelFunction feeding a renderer that uses
htmlText. The label function would simply parse the strings to get
the letters, and wrap them in a Font tag specifying the color. This
would be very easy.

Have a look into TextRange.
