I want to display a custom widget (basically a glorified Image
control) in place of the icons in a Tree component. I've not been able
to get satisfactory results (yet), here's what I've done:
1) First, I tried creating a custom ItemRenderer, but discovered that

One of the beauties of Flash's display list API is the ability to
treat almost all visual elements as the universal DisplayObject and
not be concerned with whether they're a simple shape or whether
they're a complex, multi-state movie clip.
But, when it comes to Flex framework widgets, like
So, I've been doing some contract work lately that requires that I use
Flash instead of Flex (the deliverables have to be FLAs that they can
hand off the designers to re-skin, publish, etc.). Surprise, surprise,
I'm finding the Flash IDE to be a little less than ideal.

KEY_UP event.

So, it appears that if you apply the [Bindable] metadata to a
property, Flex inserts quite a bit of logic that may not be obvious
(and certainly doesn't appear to be documented). I haven't checked the
generated AS yet, but I get the impression it does these things for you:

I'm thinking about adding an auto-save feature to our RIA so that
users can navigate away from the app and not lose any data. The common
AJAXy approach (e.g. Gmail) is to periodically send updates back to
the server. But I'd like to avoid hitting the server with that regular
network traffic if I
I'm always a bit surprised when I'm building a Flex app and remember
that there are no common cursors provided... considering that the web
browser provides common cursors (which those AJAX people get to use
for their RIAs!) and the OS provides common cursors (which those

I've got a font that we've embedded into our app that doesn't have
numerals in it. Would it be possible, using the unicode range features
of font embedding, to embed the letters from one font with the
numerals of another font (and assign them the same family)?

In our app, we call FileReference.browse for the user to select a

click event handler for a button.
Okay... I'm about to throw my laptop across the room. I am burning

in 3).

I'm wanting to globally capture the keyboard in my Flex app. I want to
be notified of every keyboard event that happens as long as the Flash
Player has the focus... regardless of whether the event happens when a
UIComponent has keyboard focus or not.
Here's what I'm doing:

I noticed that the purchase option is for Mac/Win... is the license
a dual-OS license? I.e., can I install it on my Windows desktop *and*
my MacBookPro with a single license?
If so, I'd go out and purchase it today! (Can't afford to buy two
licenses, though!)
Actually, I'm trying to avoid each DisplayObject tracing its way back
to the root (which, at any given time, it may not be able to do
depending on where it is in the DisplayList, on or off the stage, etc.).
Here's a more succinct way to ask my question:
Given that the display list is a classic
Anyone out there using the Flex SDK with Textmate? I've fallen in love
with Textmate as an editor and am frustrated each time I go back to
Flex Builder, so I'm exploring what it'd take to get Textmate married

my time is spent in
Is it possible to dispatch an event to all objects on the display
list? In my particular case, I'd like to have some additional
enter_frame like events that all display objects receive (but I
don't want it tied to enter_frame because the event doesn't
necessarily happen every frame).
