Dynamically changing size of textbox in list

Question

All- I have been having a bit of a problem solving this.
Perhaps you can help?
I have created a window that opens and displays a dictionary.
At the top of the window is a line of link buttons (A-Z). Below, is
a list component (I have tried both the list and tile list
components). When the end-user selects a link button, data from a
corresponding xml file loads into an item renderer containing two
text fields (one for the word, and one for the definition) which
gets displayed in the list component. Since each letter will have a
different number of word entries, and each word entry will have
various lengths of text, I need the the text box containing the
definition to dynamically resize, thereby resizing the item
renderer. Once this happens, I need the list to distribute the item
renderer evenly.
I have successfully loaded the text, wrote script to handle
the resize and have the list displaying the item renderers.
However, on the letters that have more than one word entry, the
list box displays the item renderers oddly. Some will have a gap
between the entries large enough to get another item renderer in.
However, when I click around on different letters, the multiple
entried ones will sometimes load correctly. When I go back to the
ones that did not, they will load correctly. Sometimes requiring
several tries. Any ideas as to what might be causing this? Any
simpler ways to accomplish my task? Thanks. -David

1) You need to make sure you override measure() to provide an
accurate
height for your renderer
2) you need to set the List's variableRowHeight property to
true.
