The truncation algorithm simply chops characters until textWidth + truncationText.textWidth fits.
You could write a similar algorithm that adds “.” until you reach the desired width. Could be slow though. There are variants that use binary-subdivision to speed things up a bit, but it is still essentially looping. An alternative would be to always have a row of “.” as wide as the renderer and overlay the two text pieces over the row and use some white backgrounds behind the text so it covers the “.” That could be faster, and the “.”would always line up in the rows above and below, but the distance between the last char and first “.” would vary. In mx components, there is a Label component and a UITextFIeld that is usually used to display text in various components. In Spark, there is just Label so there would be less confusion about which one to use where, especially for less tech-savvy folks like skin designers using Flash Catalyst. Lots of folks use mx:Label in item renderers and pay the performance cost and have the same issue with styles. And now that Spark Label is everywhere, if you change its default styles the effects show up everywhere. Which is normally a good thing. And the way to get a subset of Labels to behave differently has not changed. Use CSS via a class selector and stylename, or subclass and use a custom type-selector.

I want to fill the distance between them with "....", for example: Car.........$40,000 House......$400,000 Any ideas how to do this? Also, there is the caveat that I draw the "..." in a way that matches the "..." from Flex truncating the first item. I am using Spark Label Components, which matters because I can't change the truncationText anymore without affecting all Labels in the app (who decided to change this on the flex team i have no idea or why!).
