To add SuperScript or SubScript in Label – Flex 4

Sometimes we need to do some rich text formatting in a Label which may include “SuperScript” and “SubScript”.

Flex 4 and spark controls offer a very strong and easy way to implement this through “Text Layout Framework” .  Flex 3 can also use the same provided we have included the swc of TextLayoutFramework.  This is pre-included in Flash Builder 4.

The property we use is baselineShift of textFlow object of RichText controls.

A very similar example of how to use this in button is given at :

But to use this for a Label where we don’t need the user interaction to achieve the same we need to set the “baselineShift”.

Auto-Scrolling Issue in ADG while drag/drop

As the title suggests, this is an article about the issue that you may encounter while using SDK 3.x  and AdvancedDataGrid.

Unlike other list based components like TileList , DG etc, vertical scroll bar doesnt moves automatically to the last of the  row item while drag/drop onto the ADG. 

This can be an issue when you have a situation [and most of the time , it can be ] when you have only few visible rows and you want to drag and drop a row /item somewhere in that ADG , not necessarily between the current visible set , you expect that Scroll should move till the last row on its own.  In ADG it does not happens , because of one bug which have been already logged here.   — if you want to vote/keep a watch on to it.

Workaround is :

Please override the function showDropFeedback and then

change this line
if (collection)


if (collection)
if (dragScrollingInterval == 0)
dragScrollingInterval = setInterval(dragScroll, 15);

Hope this helps somebody facing this issue.
