Saw a post on flexcoders yesterday regarding some one wanting formatter support on NumericStepper. Played around with NumericStepper code base for around an hour yesterday night and this is what I got – <FormattedStepper>, an extended control from <mx:NumericStepper> with a formatter property which can be set to NumberFormatter or CurrencyFormatter. The control can be used as a regular NumericStepper too. I have attached a sample application and full source code also. This is version 0.0.1, may have a lot of bugs, but for starters, it works!

Sample Usage:

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" xmlns:xm="com.*" backgroundGradientColors="[#000000, #000000]"> <mx:CurrencyFormatter id="formatter" currencySymbol="$" alignSymbol="left"/>
<xm:FormattedStepper id="fs" formatter="{formatter}" minimum="1000" maximum="2000" stepSize="2"/>

I met Avinash, Kislay and Amrit from sungard last sunday at the flex users meet organized by Mrinal and Abdul. John Koch, the APAC develper relations manager of Adobe was the main guest. Raghu, I and Sameer joined in from the flex team. Amidst a conversation, Amrit pointed out that he couldnt drop a text into a specific charecter location while doing a drag drop to a text area from a list or a similar source. The dropped text gets appended to the beginning or the end of the text. Seemed to me that some simple tricks would solve this issue.

There is a UITextField instance inside the TextArea control which is protected, Hence I had to extend the TextArea control to actually prototype this capability. So, here is a hacky first draft of the drop-at-cursor-location capability into a TextArea. Currently doesnt work with htmlText, that will come soon though. Thanks Sameer for the drag and drop tips.

How does it work?

Simple! After subclassing TextArea, on mouseUp, call the getCharIndexAtPoint() method of UITextField to find out the charecter index at the cursor position. Now, appending a text at that position is very simple.
