[flexcoders] Re: ProgressEvent.bytesTotal not populated?
Do you have a way to make sure the Content-Length response header is coming across correctly? I ran into a similar problem with a flex app (in browser) and found it was related to the fact that I was using a server-side proxy that wasn't passing the Content-Length response header from the source server back to the flash player... Not sure if this will apply to your situation with an AIR app... -James --- In flexcoders@yahoogroups.com, Battershall, Jeff [EMAIL PROTECTED] wrote: I've built at AIR app that supports application update, but I'd like to show the user the progress of the updater download.

[flexcoders] Re: Updating Properties of a Component's Root State
Thanks for the idea! I'll test this myself but seems like this is a
solution for modifying an explicitly defined state property rather
than the default state... I've also been experimenting with
manually setting some properties of the move transition that is
responsible for sending the component back to it's original location.

Give an id to each state override that you need to modify. e.g.:

Then you can do:
setXOverride.value = 100;

[flexcoders] Re: Determining textHeight and textWidth when htmlText contains images...
Hmmm... yeah, I actually did create such a button and while the images had clearly loaded and were displayed the textHeight still didn't take them into account... I also tried getting an actual reference to the sprite representing the img tag within the html using the getImageReference method of the textArea's textField member. The height and width of the sprite were way larger than the actual height and width of the image for some reason... not sure why. Unless anyone has any other ideas I think I'll resort to regular expressions to parse through img tags and just use mx:Image... (In my particular use case I'm either getting a single image link or some text so that will do for me...). Alex I appreciate the help so far. -James --- In flexcoders@yahoogroups.com, Alex Harui [EMAIL PROTECTED] wrote: Never actually tried it with images.

[flexcoders] Re: variableRowHeight=true in List messing up height of last row
Alex,
Thanks for the suggestion! I've still on the learning curve for
custom actionscript components and haven't used the TextField class a
whole lot but did manage to cobble this together which seems to have
solved my initial problem. (Now I've got some others to deal with...
the widths are behaving strangely... can't seem to get them to
consistently take a certain percentage of the space...)
If you have a moment, I'd love your input on whether this
(particularly the measure method) is what you had in mind.
Thanks!

I would override measure() and see what you're getting for the

due
to fact that flow-based text is hard to measure.
A custom measure() routine would probably be better. Renderers have
their explicitWidth set when they are measured and you'll need to use
that to fix the widths of the text widgets to get an accurate height.
If it were me, I'd use a UIComponent with two TextFields and a custom
measure() method.

Subject: [flexcoders] variableRowHeight=true in List messing up height

I'm adding simple chat functionality to an application I'm working on
and have the following List displaying messages:
mx:List width=100% height=85% id=lstMessages
itemRenderer=org.MessageRenderer
variableRowHeight=true dataChange=handleDataChange(event)
dataProvider={messages}
/mx:List
here's the event handler:
private function handleDataChange(e:FlexEvent):void{
lstMessages.scrollToIndex(lstMessages.rowCount -1);
}
the MessageRenderer is as follows:
mx:HBox xmlns:mx=http://www.adobe.com/2006/mxml
http://www.adobe.com/2006/mxml width=100%
mx:Text text={data.fromName} width=20% id=lblUser

mx:Text text={data.message} id=lblMessage width=80%
color={data.color}/
/mx:HBox
What I'm finding is that with variableRowHeight=true the last row in
the List is always rendered with virtually no height such that none of
the message text shows up. You can only see that it's there by
mousing over it to see that it does display a few pixels of height (a
border or padding perhaps?). When a new message is added, the
previously squashed row displays normally and the new row is now
vertically challenged.
With variableRowHeight=false each row displays normally (except that
text wrapping in the messsages doesn't work which is why I have it set
to true in the first place...). I tried adding a call to
lstMessages.invalidate() in handleDataChange but it had no effect.
One other item of note--with only a single message in the list it
seems to display OK.
Any ideas?

Re: [flexcoders]How do States and Transitions relate?
I'm no expert in states and transitions but as I understand it you
define states if you want to add or remove children from a
component, change properties etc. The transitions define any
animations that take place going from one state to another.
Just taking a quick look at your MXML below I'm not sure you want
the AddChild, RemoveChild and SetProperty tags in your sequence
tag. I believe only effect tags should go there... Might want to
have another look at the documentation

[flexcoders] Animation of Reparenting?
I'm working on a custom component that will have a cluster of circles around it (drawn with the graphics object). I'm going to have several instances of this component in my flex app and want to be able to animate the movement of a circle that is a child of one instance to another instance of a component. From a DOM perspective this circle will change parents from one instance of my component to another. I'm pretty new to flex and would really appreciate some guidance on how to animate (apply effects) to the reparenting of one of these circles from one instance of my custom component to another. Ideas? As I've thought about this, two possible solutions are coming to mind but since I'm a rookie, I'm not sure if either one will work. 1) Re-design the custom component so that these circles aren't actually children of the component but siblings on the same parent canvas. This way I don't have to reparent the circles just move them around... 2) Animate the movement of one child circle from one instance to a location near the destination instance then destroy the circle and create another in it's place but now as a child of the destination instance. Hope this makes sense!
[flexcoders] Short-circuiting logical operators in AS3?
I'm fairly new to AS3 coming from a javascript background. I noticed
that I get an error when running the if statement below because
dataProvider[i].data doesn't exist.
if ( true || val == dataProvider[i].data) {
selectedIndex = i;
return;
}
In javascript the double OR operator (||) short-circuits such that
it wouldn't evaluate the second part of the term in the if expression
after finding the first term true. This doesn't seem to be the case
with AS3. Does AS3 support short circuiting logical operator? Is
there another way to get short-circuiting statements in AS3? (I know
I could rewrite the If statement as a two nested ifs...) anything I'm
missing as a newcomer? This is not a big deal of course, just curious...
