You might look at mx:RadioButtonGroup as an example of a non-visual component that contains visual sub-components. http://livedocs.adobe.com/flex/3/langref/mx/controls/RadioButtonGroup.html Although after reading the API description it sounds like it might have a special relationship with the compiler.

Re: [flexcoders] Re: Missing component in flexbuilder 3

That typically means that the custom component doesn't extend UIComponent or another Flex component based on UIComponent. If it already extend one of those types, I'm not sure why else it wouldn't show up. What SDK/Builder version are you using?

Re: [flexcoders] Strategies for switching between testing and deployment addresses
I'm too new at Flex to do anything fancy like reading files from the O/S
file system, so I use the Project compile option.
-locale en_US -define=CONFIG::debug,true
Then I have me some constants:
public static const DEBUGMODE:Boolean = CONFIG::debug;
public static const DEBUG_BASEURL:String = http://localhost/foo/;
public static const RELEASE_BASEURL:String =
http://www.somedomain.com/foo;;
And then in my wrapper for the HTTPService:
if ( SearchConstants.DEBUGMODE) {
baseURL = SearchConstants.DEBUG_BASEURL ;
}else{
baseURL= SearchConstants.RELEASE_BASEURL ;
}
All you have to do is change the compiler settings to debug, false and
-- voilà -- or wa-la if you like that better. There's still the
forgetting to change the compiler options issue, but it's probably a
good habit to examine the Compiler options before each compile, and this
approach inculcates a good habit.
Take this with a grain of salt; I'm new to Flex; my expertise, if I have
any at all, is not in Flex programming.

[flexcoders] ExternalInterface : debugging, DOM, Export Release Build
My browser-deployed Flex app, built in FB4, is using the ExternalInterface. The Flex app gets some search terms from the user, goes out to a webservice for some data, and then pushes some html markup out to a DIV in the HTML document using the ExternalInterface.call() method. I send the content across the bridge as a parameter to javascript function that appends a child to the target DIV. Nice and simple with the EI. However, I have a couple of questions about the logistics of developing this sort of application in FlashBuilder. When Export Release Build is chosen from the Project menu in FB4, it destroys and recreates the HTML deployment wrapper for the SWF. Is there any way for the developer to provide an HTML document template to FB, marked up with comments/metadata tags, such that only the Adobe browser-sniffing code and SWF-embed code gets overwritten but the rest of the HTML document (the user-portion) remains intact? Also, is it possible to set up a project in FB4 that uses the ExternalInterface, where you can step through code in the debugger and also see pushed content being rendered in the HTML document hosting the SWF? In debug mode it seems not possible to work with your actual HTML host document and its javascript functions-- or am I missing something obvious? I am pretty new to FB and that could easily be the case. Finally, will future versions of the ExternalInterface expose the DOM of the hosting document via ActionScript object wrappers? Thanks

[v] Title n [v]Category B [v] Title 1 [v] Title 2 [v] Title 3 . . .

A style sheet must control how the css classes in the passage excerpts are rendered. The grid might have as many as 100 rows, and each row could contain a couple of paragraphs of html text. Up to 1K each, but more typically around 100-200 characters. If I create an item-renderer using TextArea, will 100 TextAreas be created if the grid has 100 Title rows even if only 3 titles are expanded by the user?

[flexcoders] Dog woofs, Cat meows; can the same listener listen to either and how do you remove the eventlistener?
The question is at the very bottom. Here's the scenario:
Let's say I have a base class Animal, and subclasses Dog and Cat that
extend Animal.
Animal has a protected Speak() method which Dog and Cat each override:
when aDog instance and aCat Speak(), they each raise an event, a
CreatureSpeakingEvent.
class Dog extends Animal {
override protected class Speak() {
var sound:String = woof;
var eventObj:CreatureSpeakingEvent = new CreatureSpeaking (
CreatureSpeakingEvent, sound, true, false );
this.dispatchEvent(eventObj);
}
}
class Cat extends Animal {
override protected class Speak() {
var sound:String=meow;
var eventObj:CreatureSpeakingEvent = new CreatureSpeakingEvent (
CreatureSpeakingEvent, sound, true, false );
this.dispatchEvent(eventObj);
}
}
In the main class, which can instantiate either or both of these
animals, a listener is attached to the CreatureSpeakingEvent event:
var aDog = new Dog();
var aCat = new Cat();
aDog.addEventListener(CreatureSpeakingEvent, onCreatureSpeaking);
aCat.addEventListener(CreatureSpeakingEvent, onCreatureSpeaking);
The onCreatureSpeaking() function listens:
private function onCreatureSpeaking(e:CreatureSpeakingEvent) {
// is the following cast to the base-class Animal acceptable?
Animal (e.target).removeEventListener(CreatureSpeakingEvent,
onCreatureSpeaking);
}

I am having trouble with an override, getting Method marked override
must override another method.
No problem at all doing this:
in the BASE CLASS:
protected function foo(): void{}
in the SUBCLASS
override protected function foo(): void{}
But the error given above occurs here:
in the BASE CLASS
protected function onResult(e:ResultEvent, token:Object=null):void {}
in the SUBCLASS
override protected function onResult(e:ResultEvent,
token:Object=null):void {}
I don't see why it's not working. All of the requirements set out here
seem to be satisfied:

It appears that you cannot override a function with optional parameters?
protected function foo(a:String, s:String=null): void {}
Isn't the signature considered the same if you do this?

[flexcoders] question about inheritance and events and overriding methods
Let's say I have a class MYHTTPSERVICEBASE which extends
mx.rpc.http.HTTPService. This base class of mine checks whether it is
being run in debug mode or release, and sets the base URL to localhost
or the remote host. Then I have individual http service classes that
extend MYHTTPSERVICEBASE.
I want my http service layer to dispatch messages that my GUI layer will
be listening for:
publicfunction execute() : void {
myResponder = new AsyncResponder(onResult, onFault);
this.resultFormat= HTTPService.RESULT_FORMAT_TEXT;
var token: AsyncToken = this.send();
token.addResponder(myResponder);
}
privatefunction onResult(e:ResultEvent, token:Object=null):void {
// Got Data? then instantiate and dispatch a bubbling event
object that encapsulates the data
// the GUI layer will be listening for this event
}
Questions:
Can the event object be dispatched from within the MYHTTPSERVICEBASE?
Will the GUI hear it if it's dispatched from the base class?
In a class that extends MYHTTPSERVICEBASE, can I override the onResult()
method that has been registered with the Responder by the base class?
Thanks for the help!

I'll take a crack at it.
Can the event object be dispatched from within the MYHTTPSERVICEBASE?
Sure. I think there may be a separate underlying question here
though. Are you asking how? Maybe you can clarify?
Will the GUI hear it if it's dispatched from the base class?
First of all, if the service classes you're talking about aren't on a
display list (it's very likely they are NOT) then an event doesn't
bubble in the traditional sense. Nothing will hear the event unless
it specifically has added an event listener to your service object.
So if you want any view component to hear the event being dispatched
by your service object, the view component will need to add an event
listener to your service object. Depending on the framework you're
using, there may be some other mechanism whereby the view can hear
about a command's completion. Something else you can do (though some
architecture developers will cringe) is dispatch the event off the
stage, the system manager, or the base application from your command
and then the view would add an event listener to whichever object that is.
In a class that extends MYHTTPSERVICEBASE, can I override the
onResult() method that has been registered with the Responder by the
base class?
Yes. In the case of your sample code, if you override onResult in
your class that extends MYHTTPSERVICEBASE, it is the overriding
function that is passed into the responder. That is, when you
reference onResult, you're referencing the most extended onResult
function, not just the onResult function in the class from which
onResult is referenced.
I hope that makes sense. It's very likely I misinterpreted your
questions.

[flexcoders] HTTPService Responder ResultEvent -- how to know when the JSON data sent via HTTP are complete?
I started learning FlashBuilder/Flex by diving in and writing an AIR application against SQLite with asynchronous connections and Responder objects. The responder's resultsHandler is passed a flash.data.SQLResult object that exposes a complete status property. Lovely. Now I am trying to rewrite that AIR application as a browser-deployed Flex app using an HTTPService against a RESTful webservice that returns JSON data. The webservice is working, and the Flex HTTPService is pulling the JSON string down, but there doesn't seem to be anything analogous to the complete property that was available with the asynch data connection in the AIR app. Not so lovely. The result-handler specified in the HTTPService responder has two parameters, the ResultEvent and the AsyncToken. The ResultEvent exposes a statusCode property. The result-handler can be called more than once. The ResultEvent.statusCode = 200 each time the handler is called. How do you know when the remote data are complete? I will keep googling as I'm sure this question must be commonplace, but so far I haven't found the answer. Thanks for the help.
Re: [flexcoders] HTTPService Responder ResultEvent -- how to know when the JSON data sent via HTTP are complete?
Jeff,
Thanks for the reply. I am confused by the behavior of my Flex app. The status
bar says Transferring data from localhost... and that status message never
goes away. But, as you suggested, the data are complete: I pop the raw JSON
string returned by the webservice into a TextArea, and it's all there, a string
literal representing an array of objects:[{...},{...},{...}], and the
string literal decodes into a well-formed ActionScript array.
Is there something my results-handler has to do to clear that status message?
Tim
Maybe I’m missing something here,
but to my understanding when the result event of your HTTP service fires, your
call IS complete. You should have access to the json string that was
pulled back from the service. Is there something else you need that the
json string doesn’t’ supply?

[flexcoders] possible to derive rowIndex from DataGrid's rightClick event?
In an AIR app, I'd like to be able to know what row of a DataGrid the user has right-clicked on.* The rightClick event of the DataGrid is a MouseEvent and does not expose rowIndex (unlike the rowClick event which is of type ListEvent). Is there a way to derive the rowIndex in the grid's rightClick eventhandler? Thanks *I'm hoping to make a CheckBoxDataGrid interactive in two ways -- normal check-box multi-selection mode, which is working fine, but also a right-click-on-single-row mode, where the row is not selected but is temporarily the subject of the user's attention -- possibly for a context-menu.
[flexcoders] padding P element with CSS in htmlText of TextArea
While I've been able to apply some CSS styles (e.g. fontFamily, fontSize, fontWeight, fontStyle, letterSpacing) to the content of p elements and to indidivual class selectors in the htmlText of a TextArea in an AIR application (FB4 beta2), attempts to set other styles, such as padding and margin, have not worked. Are padding and margin not implemented? If not, will they be? CSS + HTML are a powerful duo. I hope Adobe has plans to exploit this capability fully for the TextArea in AIR applications. For many text-presentation purposes CSS support would be entirely adequate, and typographic control would offer far more precision and granularity than is actually needed while introducing unnecessary complexity. Not that typography isn't a very slick feature, but please don't let CSS+HTML fall by the wayside. Regards Tim
Re: [flexcoders] Flex 3: AIR Local Database
The answer to your question about large scale is yes, AIR + SQLite can handle large datasets but with some caveats. I have a SQLite database that is several hundred megabytes. The main tables contain 4 million rows, 275000 rows, and 3500 rows. Queries that join these tables, when the query makes use of indexes, execute in under 100 milliseconds. Snappy. However, some things in the AIR implementation of SQLite are causing index optimizations with the LIKE() operator not to work, both in regular statements and in prepared statements. I am not sure what these things are because the differences between the AIR implementation of SQLite and SQLite proper haven't been documented. They could be things like overloading certain core SQLite functions, or compiling statements/prepared statements with one of the functions that cause the optimizer not to use an index. As a result of these mysterious things, if you run a query like SELECT * from MEMBERSHIP where MEMBER_LASTNAME LIKE 'Johns%' the query will do a full table scan. Do a more complex column value starts-with query that involves joins, and the table scan can translate to very poor performance. For example, when I execute my query at the SQLITE3.EXE command-line, where the index IS used, the query executes in under 100ms but the identical query takes 45-50 seconds in AIR. Also, to keep the front-end responsive when working with large datasets, you will have to use asynchronous data connections not synchronous connections. The coding is somewhat more complicated but also I found the AIR debugger to be less than robust when working with asynchronous connections and data events. However, everything worked OK with Responders, so I'd recommend the use of responder objects over the event-dispatch architecture. I have no experience to offer you with concurrency issues and SQLite. My AIR + local-db application is single-user. Regards TR jwc_wensan wrote: In all the articles I have read and some examples, it only talks about using SQLite as the database on the users' PC/Mac. Is that the only database that can be used locally? Can that database handle a large-scale commercial AIR app with tens of thousands of records? Also, since the AIR app is installed on the users PC/Mac, is there any reason to use mx:Modules? If the user needs/requires that data remain local, is AIR the best solution? Does Flex 4 solve any issues? Thoughts, options, suggestions? Thanks in advance, Jack
[flexcoders] where to get official answer to question about AIR's SQLite implementation and LoadableExtensions mechanism support?
A simple function I need does not exist in the SQLite engine core but the SQLite gurus are telling me to write my own function in C and load it at runtime as a loadable extension. (I have good reasons, BTW, for not wanting the function to execute in the client--it really belongs in the back-end.) http://www.sqlite.org/cvstrac/wiki?p=LoadableExtensions The LoadableExtensions mechanism is disabled by default, and Adobe in its implementation of SQLite may not have enabled the LoadableExtensions mechanism; or if it is enabled, a developer does not know whether it is officially enabled or an undocumented use-at-your-own-risk feature. Where would one get an official answer to the LoadableExtension supported/not-supported question? I've tried the AIR forum at Adobe but my question was not answered there. Thanks

[flexcoders] launching popup TitleWindow from a reused mxml component
I posted a question the other day about how to prevent a popup from being dragged outside the bounds of the application window. Since I'm fairly new at Flex, some obvious things are not immediately obvious to me. I think my popup window can be dragged outside the main application window because this in my method call below: PopUpManager.addPopUp(popwin, this, true); actually refers to an isntance of my (reusable) mxml component which is launching the popup, not to the main application window. If the parent DisplayObject referred to by this is not the main application window, is the default behavior that the popup can be dragged outside the main application window? Thanks
[flexcoders] PopupWindow dragging and enforcing main app window bounds
First, thanks to Tracy for answering my question about the columns array of the
DataGrid.
My question relates to dragging popup-windows.
It's possible to drag a popup window outside the main application
window's bounds, and if the user happens to release the
mouse button at the wrong moment, the popup window can no longer be
grabbed.
My popup is defined in ActionScript like this:
public class MyPopupWindow extends TitleWindow { ... }
and is instantiated like this:
var popwin = new MyPopupWindow();
var isModal:Boolean=true;
PopUpManager.addPopUp(popwin, this, isModal);
How would I get a reference to the main application window's bounds?
MyPopupWindow instances could be popped up from deep inside nested containers.
Do I keep getting parents of parents until there are no more parents to get?
If I pass this rectangle to the MyPopupWindow constructor, can MyPopupWindow
use those values to prevent itself from being dropped outside those confines,
in the
stopDragging() method that it inherits from Panel, and relocate itself? What
properties contain its its current location relative to the main window's
bounds?
Or do I need to implement this in the class instance that invokes the
PopUpManager.addPopUp method?
Thanks
RE: [flexcoders] how to wait for more than one httpserivice/remoteobject result to finish?
You don't really get much in the way of thread control in Flex, but a neater
way might still be to create something of a pseudo-barrier.
At the time each object is fired, you would also add a token to the barrier,
latching it and increasing the counter on that token. Each event listener
could then call off to the barrier, passing the same token fired as a property
of the event to decrease against that token on the barrier - at the point all
tokens are unblocked (ie, reach 0) you can open the barrier. Your other code
would sleep (I was almost going to say spinwait... hm, no :) until the barrier
is unlatched.
This could avoid you needing to write a handler for each event - the problem
with the below example is what happens when you need three, or four, of seven
events to be waited on. Just something to give some thought to anyway.

[flexcoders] Re: Question about event.label
For Menu controls, if the data provider is an Array of Strings, Flex
uses each String value as the label. When a menu item is clicked, the
item's label is passed to the ItemClickEvent's label property. It would
be necessary to use name-value pairs, in the dataProvider, if you used
the Menu's labelField or labelFunction properties.

RE: [flexcoders] Any suggestion for server (java) side run-time styling solution?
I'm a bit puzzled that you mention the need to compile in changes. Surely a SWF can load in an external css file? If so, could the swf not typically be made to access a CSS file (via whatever method) specifically for that user via their credentials, or via a token? This would allow run-time loading, and the ability to store, modify and retrieve it however you like on the server-side.

Hi, We read the documentation about loading styles from out side but unfortunately they all discuss loading swf compiled files. While it is possible to let an editor edit the style on the server and then run the compiler on the server to generate a swf file, it looks like redundant complexity. The server is a cluster and it'll require additional set-up for every server. Does anyone have a different solution? Just to clarify - the requirement is to have the client load the style in run-time. This style should be manageable on a management interface running on a java server.

If you cast your service call result to a [Bindable] collection, and bind the collection to the ComboBox's dataProvider, the ComboBox should display populated.

If not, the data will get pushed to the ComboBox; when it arrives. -TH --- In flexcoders@yahoogroups.com, flexaustin flexaus...@... wrote: So I have a tabNavigator with 3 tabs.

The issue that I have a combobox on tab#3 of the tabNav. and when I set creation=all and tab#3 is selected the combobox is empty. If set the creationpolicy=auto the data shows up in the combobox. I assume that what is happening is that tab#3 is getting created imeediately before the data arrives.

[flexcoders] Re: TileList Item Spacing
There isn't a horizontaGap or verticalGap between the tiles in a TileList. So, you'd have to use an itemRenderer to fake it. Add a transparent container to the itemRenderer, that contains the itemRenderer content; centered within the transparent container. You can then adjust the perceived gaps with padding, and/or by adjusting the rowHeight/columnWidth of the TileList. -TH --- In flexcoders@yahoogroups.com, wwwpl ww...@... wrote: I need to increase the spacing horizontally and vertically between the items in my TileList.

You'll need to adjust the individual series columnWidthRatios and offsets so that series 0 and series 1 start at the same x position, and (obviously) series 1-4 take up the space of 5 series columns. You'll need to have an itemRenderer for series 0. Override updateDisplayList() and set the unscaledWidth to be wide enough to span series 1-4.

[flexcoders] Re: Image Loader COMPLETE event wont fire for some images
Well, probably a question better answered by Alex. I suspect that the
transparency is adding to the file size and hitting the size limit.
But, at this point, it's just a guess. Try cropping the image down to
see if you get to a point that it works.

[flexcoders] Re: Possible to change the Fill Color for ColumnSeries on itemRollOver?
Ha, yeah if it works you get extra points. :) I tried using the chart's
itemRollOver event, but ran into a snafu trying to drill down and change
the fill of the BoxItemRenderer. It seems to have a getStyle method,
but no setStyle(). Got past that, but the stroke style got me. Would
probably be best to extend the Chart and handle the item roll-over
there; with styles. Someone else can do that though.

[flexcoders] Actionscript on JSR223
Does anyone happen to know of any JSR223 (Java platform scripting) implementation(s) of ActionScript for dynamic use? I'm currently looking through a lot of our business data validation logic which is implemented in two places arguably unnecessarily - both on the front-end in AS and then again on the back-end in Java. The scripting.dev.java.net project page still seems to be absent of any AS interpreters. It would seem far more logical to be able to just implement this once in a single language. Two options I can see are using a Java-AS convertor, or to write this all in AS and validate the data again on the back-end against the same code. The latter would be preferable, mostly due to the stigma around here about generated code. Though much of this code might work as javascript if we dropped the typing on data, that's far from an ideal solution. Any project suggestions here would be appreciated.

It's been a year since my last question and this one seems like an interesting problem. First to give you some background, I'm making a stats page for a game. The game consists of three rounds and each round consists of five clicks. Each click can either add or subtract points from your score. So after each round I'd like to show a line chart to plot out the value of the users' points (y axis) against each click (x axis). Since the second round starts with the points from the first and the third from the second, the graph of the entire game (all three rounds) is continuous. In order to graphically distinguish which clicks came from a certain round, I would really like to have the line be broken up into three colored segments. I couldn't find a good solution so I tried to hack my own by simply drawing three individual segments head to tail. However, this doesn't work for two reasons: the line needs to be continuous and it needs to show data tips. The three segments at a glance appear to be continuous, but I set the line to be curved so it's smooth. Back-to-back lines don't curve corners and all of a sudden a smooth line has a sharp angle. Secondly, since the ending point of the first or second round is the starting point of the next round, hovering over that point on the chart displays two data tips; one for each round (displaying the same point values). Does anyone know of anything built in to simply say starting at x-value X change line color to #xx? Thanks!

In the past, resizing with Image using img.resize((height, width),
Image.ANTIALIAS) (where img is mx.controls.Image) has worked - I'm sure
there'd be a similar method for BitmapData. Of course, if you're not
specifying antialiasing and the method call doesn't assume it by default,
then yeah, you're going to get horrible image quality on downsize as a
typical algorithm will pick nearest-neighbor to the new target pixel.

Subject: [flexcoders] Bitmap downsampling
Hi,
I'm having a lot of trouble with down-sampling a bitmapData.
I tried the smoothing option first
public function produceResizedBitmapData(image:DisplayObject,
transform:Matrix):BitmapData
{
var temp:BitmapData = new BitmapData(image.width, image.height, true,
0x00FF);
temp.draw(image);
var clone:BitmapData = new BitmapData(image.width*transform.a,
image.height*transform.d, true, 0x00FF);
clone.draw(temp, transform, null, null, null, true);
temp.dispose();
return clone;
}
except the quality was poor, once the image was of a certain size.
For example scaling a 2500px image down to 200px.
I've tried using clevrLib plus a pixelBender bilinear sampler but no go.
I've noticed it works in picnik so it must be possible.
Can anyone push me in the right direction.

This app initializes the text component with some htmlText using a

Everything's fine. Now change to an embedded font, and note the

The reverse happens if I initalize the field with an embedded font

[flexcoders] Re: htmlText truncation when changing from embedded to device font
One other thing that you could try would be to create the TextArea
dynamically each time with AS, set the styleName, set the text and
addChild(). You would have to removeChild() each time as well. Not
sure if this would solve your problem, but maybe it's worth a try.

[flexcoders] Re: Time Difference between two columns in DataGrid using itemrenderer
Hi Don,
The itemRenderer's data Object contains BOTH fields for that row in
the dataProvider. You can start by trying to pass the date strings into
a DataFormatter and cast as Date, or try DateField.stringToDate(). If
the format of the date string isn't compatible, and you can't change
what the server sends, you might have to parse the string manually and
create a Date object from scratch. Once you have the two date strings
converted to Dates, you're ready to compare them. There are a few
utilities that you'll be able to find through a search, that work with
comparing dates. I found this very quickly (looks like it rounds to
full days though):
private function calcuateDays( start:Date, end:Date ) :int
{
var daysInMilliseconds:int = 1000*60*60*24;
return ( (end.time - start.time) / daysInMilliseconds );
}
You'd probably want to use a Number instead of int, and round the number
as desired. And, probably search anyway.

Not out of the box. But, you could extend Legend and assign a custom LegendItem to legendItemClass. LegendItem is a UIComponent, so it would be easy to extend and add mouse event listeners/handlers.

[flexcoders] Re: Extending Custom Panel with RadioButtons - Help
Ok, so take maps out of the RadioButtonPanel AS component and make the
startLocation RadioButtonGroup public. Next create a Event in the
component, that will be dispatched when the radio buttons are clicked:
After the import statements add:
[Event(name=changeMap,type=flash.events.Event)]
Then in changeStartType(), replace the if statement with:
var event:Event = new Event( changeMap );
dispatchEvent( event );
Now you can listen for the event:
wallyk:RadioButtonPanel changeMap=handleChangeMap( event )/
The event handler would then perform the changes, from outside of the
component:
private function handleChangeMap( event:Event ):void
{
if (event.currentTarget.startLocation.selectedValue == address){
start_txt.text = Enter Starting Address;
}else{
start_txt.text = Choose Your Airport;
}
}
It makes sense to do it this way because the content of the panel could
change and you might want to re-use your component..

2) Add this function:

test.invalidateSize();
}
3) On the ComboBox change event, execute callLater(updateTextSize);
Note: If you use embedded fonts, a boldface font must be available for

Hi all,
I've seeing some strange behaviour with a mx:Text component using
htmlText.
It seems that when the fontFamily of the text component is changed at
runtime from an embedded font to a device font (or vice versa), the
content is truncated, and the HTML formatting lost. However, when
changing from one device font to another (or one embedded font to
another), it works just fine.
Take this example (view source enabled but without the actual font
files included - any OTF should work fine):
http://dev.nx.sg/lab/fontchange/FontChange.html
This app initializes the text component with some htmlText using a
device font (_sans in this case). Once loaded, try changing the font
to another device font (e.g. Courier New or Myriad) with the dropdown.
Everything's fine. Now change to an embedded font, and note the
truncation and loss of formatting.
The reverse happens if I initalize the field with an embedded font -
changing to another embedded font works fine but changing to a device
font ends up truncating again.
Anyone got any ideas how to make this work?
Thanks,
Toby.
