Subject Re: s:Spacer (was Re: Missing Spark components)
Date Thu, 01 Mar 2012 20:05:33 GMT
Wow, the thread on this simple topic has gotten quite large.

One of the main complaints against how Spark was originally written was
that it was too inconvenient.   That is the main reason the ship date for
Flex 4 got delayed.  We need to find a good balance point between
ease-of-use and strict compositability.

I'm against having a SkinnableSpacer class, but I'm all for having a Spacer
class.  It would just be a subclass of Rect with no extra properties or
anything.  There are two main reasons why I think we should have it: 1)
people coming from MX expect it, and 2) semantically it's different from a
Rect.

While it's true that someone can easily write their own Spacer class to
achieve this, but lots of people don't use Rect, which is more
light-weight.  Plus, I think this case is really common and something we
should support.

I think it should be a subclass of Rect for performance reasons...if people
need something else, they will figure it out.  If people want a Skinnable
or fancier spacer, they can create a simple custom class for their own
purposes.
