RE: [flexcoders] Text Character Spacing

[Gordon Smith]

Flex 2.0.1 added a "letterSpacing" style for components like Label and
Text.. These styles are listed in the LiveDocs for 2.0.1 at
http://livedocs.macromedia.com/flex/201/langref/index.html

 

You'd write

 



 

to get 10 extra pixels between each letter.

Thanks for the info.

 

I've looked at, but not sure exactly how to implement it.

 

I'll continue to look for examples.  At lease I know what

Look into flash.text.TextFormat.letterSpacing.  There might be an
equivalent style as well on text UIComponents.

It's rather late here, so I’ll update all source and posts with a proper
license or something similar tomorrow. Thanks for the input Daniel it’s
cleared some things up. I want people to be safe using it, at the same time
I want to of course protect myself from liabilities.

  As for copyrights vs. licenses

  If you own the code (which if you wrote it you probably do), then you own
the copyright.  A license is simply giving someone permission (limited or
otherwise) to use the copyrighted material.  If you give the copyright to
the public domain, then no one owns the copyright and thus there is no
reason why someone would have to license the copyrighted material.

  As far as practices and standards for people like us, we can talk the
issue into the ground on what we want, but the bottom line is that if
there's no licensing statement with the code, people aren't safe using it
(legally speaking).  If you want to be nice, include one.  If you're
paranoid, email the author.  Lastly, you don't need to be a lawyer to write
a license, especially if it's really simple.  For example, if you want to
let people use code as they see fit, simply state in plain English (or any
other language for that matter) something like "You can use this for
anything" or "I give this to the public domain."  If you're paranoid you
could include, "I am not responsible for any harm this code does to your
computer."  Done and done, no lawyer or standard needed.

  Lastly, if you're employed by a company you might not have the right to
give the copyright or licenses because (usually) anything you write on
company time is owned by the company.  (Don't ask me to define "on company
time.")  This is sometimes also true for freelance work, but not usually.

  Personally, I'd say look for the licenses, state what you want your code
used for in layman's terms or use a standard, and email the author if you're
confused.

  Most of them are not explicitly associated with any specific

  Sure would be nice if there could be some standard practice of

  Maybe there already is some presumed license or disclaimer

It was down to the cross domain I created one on the API server and

[flexcoders] Alex's Distortion effects

The example has the following code:

Do you run this or integrate into other code?

I love these distortion effects, but don't have a clue how to

even though paths to classes are correct. Can anyone help me? Thanks

Hi again,

I've got a simple save case working as far as I can tell (from
debugging the server java side, everything is OK after leaving the
HibernateAssembler.java updateItem() method.

But the result never gets back to the client... I have a responder
registered to the call like so:

call = service.commit();
call.action = "save";
call.addResponder(responder);

And my responder has both fault and result methods. I know the
responder is registered because I was getting faults for a long time,
and those were firing the fault handler. But now that I think I have
the save going successfully, I'm not getting anything back.

I've turned on FDS logging for messages, see the trace below. Seems
like the "ACK" message is being sent... 

Any ideas?

thanks,

RE: [flexcoders] Re: FDS DataService.commit() doesn't trigger responder result()...?

[Jeff Vroom]

I personally attach to the server after it is started.  It is a pain to
specify all of the jar files and keep that up to date in my case since
the jars change a lot (though I have gotten that to work too...).  

 

Unfortunately the exact way is dependent on the app server and I am
still using jrun (yeah, been meaning to switch for a while!)

 

For Jrun, I add this to the standard java command line args it uses:

 

  -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=2005

 

Then my eclipse debug target is created from the "Remote Java
Application" configuration.  I specify localhost and 2005 for server and
port.

 

Debug logging on the server is in WEB-INF/flex/services-config.xml.
Search for level=, change that to Debug.  Make sure that "Message.*" and
DataService.* are in the patterns.  I personally don't like the
"Endpoint.*" unless I'm debugging serialization problems since it is
pretty verbose and duplicates a lot of the Message.* stuff.

 

On the client, you can use the  in your MXML.  It goes
to flashlog.txt - same place as the "trace" statement output.

 

Jeff

No answer unfortunately, but I do have two questions...

1) how do you manage to debug your server side jave code? I am
running under JBoss and using Eclipse as my IDE for both Java and
FlexBuilder and I can't figure out how to set breakpoints in my Java
code or attach a debugger to the server.

2) how do you switch on the FDS logging?

not the response you were hoping for I am sure, but you would be
helping a fella out :-)

[flexcoders] Returning 'this' from an overridden method?

[David_Stafford]

Please pardon this simple-minded question from an AS3 novice.

My base class often returns 'this' from methods which makes it 
convenient to write code like:

  camera.move( 10, 12 ).rotateX( 45 ).rotateY( 90 );

The problem comes when code extends the base class and overrides one 
of these functions.  The compiler insists, correctly, that the return 
type of an overriding function must match the one in the base class.  
What I want to do is return the 'this' object that is of the type of 
the derived class.  Is this possible?

The following is a contrived example to demonstrate.  It won't 
compile because the overridden function in the derived class wants to 
return a type of MyCamera rather than Camera:


public class Camera
  {
  var x:int = 0;
  var y:int = 0;

  public function move( x:int, y:int ) :Camera
{
this.x += x;
this.y += y;

return( this );
}  
  }

public class MyCamera extends Camera
  {
  override public function move( x:int, y:int ) :MyCamera
{
super.move( x, y ); 

if( x < 0 )  x = 0;
if( y < 0 )  y = 0;

return( this );
} 
  }

Re: [flexcoders] Intellectual property or licensing of posted/blogged work

[Daniel Freiman]

I will now pass myself off as a legal expert despite the fact that I haven't
attended law school...so anyone with authority should overrule my opinion.

Generally speaking, if the owner (which is usually the author) publishes the
code on the web, then you are allowed to look at it.  They showed it to the
public, the public gets to see it.  (It's the same theory that while a
billboard is still copyrighted, you can't tell people not to look at it.)
You can even tell other people about it and where it is (although you can't
necessarily give them a copy yourself).

As far as using it in your own projects, that depends entirely on the
license.  Sorry, there is no standard.  However, many blogs and most adobe
products/solutions/projects (including many you mentioned) are pretty
explicit on what you can do.  I assume if you publish things on this list
then you're ok with people using them as they see fit, but that's a personal
assumption, not a legal one.  Maybe there was something in the signup that i
missed which said this list is in the public domain, but I don't remember
it.

[flexcoders] Printing High Res Images

[zgaff]

Hi Everyone,

   Does anyone know how to print a high res images in flex 2. What I 
mean is if I have and image that is 1200 DPI by 1200 DPI and my printer 
has a resolution of 600 DPI my image should print out a 2 inchs by 2 
inchs. I set the size for my display the printout is incorrect.

Thanks for any assistants

[flexcoders] Putting a Rectangle around a "selected" line in a List component

[Michael]

I'm fairly new at this and am trying to extend a List component so 
that a rectangle will appear round the selected line (and around the 
roll-over) instead of a solid color.

I'm assuming that the focusRect property that is inherited from the 
InteractiveObject is the one I need to deal with, but I can't seem to 
figure out how to use it.

Are there any examples out there that I could see??

[flexcoders] Re: Intellectual property or licensing of posted/blogged work

[Engkee Kwang]

Just to expand on the original post, there are at least 3 issues I 
can see with the lack of clarity on posted work.

1. The first relates to copyright and as pointed out, the US law 
appears to be pretty clear. If that is the case, then minimally, it 
would be appropriate to include in the software some attribution to 
the original author, in some forms, likely to include but not limited 
to name, email address, etc. Even if not required, it would be good 
common courtesy and for that, we would need to have some verbages 
included with the posted work.

2. The second relates to licensing or financial terms. While software 
folks may be inclined to make the most liberal interpretation, I 
don't think corporate lawyers would agree.

3. The third relates to plagiarism. Intentionally or not, if I were 
to avail myself to posted source code, there is a high likelihood 
that even if I were to then recreate similar functionality, there 
will be a high degree of similarity to posted work.

Bottom line is that I can imagine companies producing commercial 
software would be very uncomfortable with the degree of ambiguity and 
subjectivity.

Re: [flexcoders] Intellectual property or licensing of posted/blogged work

[Ben Stucki]

Dan,

That's one of the best descriptions of copyrights and licensing I've seen in a 
while. I used to release code under Creative Commons, but I am now recommending 
the MIT license to anyone releasing code. It's short, legally sound and widely 
accepted. Here's the link.

http://www.opensource.org/licenses/mit-license.php

P.S.  Engkee, I've got an updated Reflection component being released under the 
MIT license soon. Working on the examples now.

As for copyrights vs. licenses 

If you own the code (which if you wrote it you probably do), then you own the 
copyright.  A license is simply giving someone permission (limited or 
otherwise) to use the copyrighted material.  If you give the copyright to the 
public domain, then no one owns the copyright and thus there is no reason why 
someone would have to license the copyrighted material.

As far as practices and standards for people like us, we can talk the issue 
into the ground on what we want, but the bottom line is that if there's no 
licensing statement with the code, people aren't safe using it (legally 
speaking).  If you want to be nice, include one.  If you're paranoid, email the 
author.  Lastly, you don't need to be a lawyer to write a license, especially 
if it's really simple.  For example, if you want to let people use code as they 
see fit, simply state in plain English (or any other language for that matter) 
something like "You can use this for anything" or "I give this to the public 
domain."  If you're paranoid you could include, "I am not responsible for any 
harm this code does to your computer."  Done and done, no lawyer or standard 
needed.

Lastly, if you're employed by a company you might not have the right to give 
the copyright or licenses because (usually) anything you write on company time 
is owned by the company.  (Don't ask me to define "on company time.")  This is 
sometimes also true for freelance work, but not usually.   

Personally, I'd say look for the licenses, state what you want your code used 
for in layman's terms or use a standard, and email the author if you're 
confused.

[flexcoders] Semi-noobie architectural style question

[rumpleminzeflickr]

Hi there,

I have a main app, with a lot of sub custom components.

I've created a singleton class that i'm using as a controller. 

what I want to know is, do I have to define access to that singleton 
class in every custom component, or is there some way to 'pass' the 
instance of it down the line and make it available to all.

Sorry if this is a dumb question, I tried searching without an answer 
so far :(

[flexcoders] Using History in a wrapper

[Jack Park]

The templates call for a URL: history.html
My question has to do with behaviors in a servlet environment. Here's the
story.

I call the history file simply with /history rather than history.html. This
means that my template line of code reads:

   AC_FL_RunContent(
   "src", "/swf/FirstFlex",
   "width", "100%",
   "height", "100%",
   "align", "middle",
   "id", "FirstFlex",
   "quality", "high",
   "bgcolor", "#869ca7",
   "name", "FirstFlex",
   "flashvars",'historyUrl=/flex/history%3F&lconid=' + lc_id + '',
   "allowScriptAccess","sameDomain",
   "type", "application/x-shockwave-flash",
   "pluginspage", "http://www.adobe.com/go/getflashplayer";
   );

where the affected line was:
   "flashvars",'historyUrl=history.html%3F&lconid=' + lc_id + '',

Right now, I feel a bit dense. I'd like to know how others are painting the
history iframe through a servlet. That's because the contents of
FirstFlex.swf are not appearing even though the servlet log trace clearly
states that the swf, itself, was served.

[flexcoders] About a warning message when using an RSL

[arcencie1978]

Hi guys,

I've just succeeded in making a flex library project

and come up with a myLibrary.swc.

Yet my problem is that the warning message

pops up every time a sub-application is being loaded...

Is it just the way that RSL works or am I missing something???

What is strange is that when I run the application in the Flex 
builder

there's no warning message!

But if I run the application in the bin folder or on some web page,

this bothersome warning message just pops up on and on...

For your refrence, I set the RSL URL at the Library path for my 
project like myLibrary.swf. Isn't this what it is supposed to be?

Please correct me if I am missing something...

Thank you very much~!! 

[flexcoders] Re: How can I test a UIComponent to see if it is user editable?

[dougmccune]

I don't think there's a good answer to this question. There's no way
to figure out via AS whether a component MIGHT dispatch a given event.

I did a search on livedocs to try to find all classes that dispatch a
change event. This only seems to include base classes, so subclasses
of any of these controls won't show up, so you'd hve to figure those
out. Also note that this doesn't mean that some classes might dispatch
other events that signify change that aren't specifically the same
"change" event. And these change events don't necessarily mean "user
input" either. All it means is that the component dispatches an event
called "change".

Here's the livedocs search:
http://livedocs.macromedia.com/cfusion/search/index.cfm?loc=en_us&term=site%3Alivedocs.macromedia.com%2Fflex%2F201++%22change%3DNo+default%22&action=Search

And here are the classes that come up:
mx.controls.RadioButtonGroup
mx.controls.sliderClasses.Slider (which means HSlider and VSlider as well)
mx.controls.ColorPicker
mx.containers.Accordion
mx.containers.ViewStack
mx.controls.DateChooser
mx.controls.NumericStepper
mx.controls.Button
mx.controls.DateField
mx.controls.PopUpMenuButton
mx.controls.ComboBox
mx.controls.TextInput 
mx.controls.TextArea
mx.controls.Tree
mx.controls.listClasses.ListBase (so that would mean all list controls
like List, TileList, DataGrid, etc)

So your best bet is probably to put together a more complete list of
each component you want to define as having "user input" and then just
check against that list using the "is" test as already mentioned. But
I think the basic answer to your question is no, there's no good way
to do this.

[flexcoders] FDS2 stuck when resultset is too large

[Carlos Rovira]

Hi,

One of the teams here working on a large FDS2 application found a strange
problem. When the resultset retrieved from FDS2 pass a number of rows the
dataservice hangs. It always happens when the rows pass a fixed limit.

It seems like FDS waits for a new request and if you throw a new request
just after the large-row-request (another fill), the first one ends without
problem.

Anyone could bring some explanation about this issue?.

Thanks.

[flexcoders] Poor man's PUSH technology (aka reload data using timer)

[oneproofdk]

I am building a internal app for my company, where we would eventually
pursue FDS for it's push capabilities - updating the users view when
backend data changes.

Until then, I'm thinking about making a function that will get
triggered by a timer, e.g. every 60 seconds, it should retrieve data
from the server and then compare it to the data currently displayed in
the app [Binded]. Then if data has changed, it should update the
specific data in the ArrayCollection.

Any pointers to how I could accomplish this ?

Im thinking a function "dataTimer" that would call a function
"getData", that function would then compare each row in the dataset to
the data currently "in memory" in the app. If there's a difference, it
would update the data OR completely replace the currently used
dataset. (only I guess that would make the app flicker?)

Any help is greatly appreciated.

Thanks,
Mark

Re: [flexcoders] Semi-noobie architectural style question

You could store it as a member of your Application.
Then you are able to access it by parentApplication.controller

  Hi there,

I have a main app, with a lot of sub custom components.

I've created a singleton class that i'm using as a controller.

what I want to know is, do I have to define access to that singleton
class in every custom component, or is there some way to 'pass' the
instance of it down the line and make it available to all.

Sorry if this is a dumb question, I tried searching without an answer
so far :(

Re: [flexcoders] Re: Tutorial zoom in a linechart

[Brendan Meutzner]

I would guess that performance on rendering the chart would be faster
passing it a smaller dataset to work with... setting the minimum and maximum
would still require that the chart filter out non-visible data... just a
guess though...

This is the correct behaviour. The derived class is MyCamera and any
reference to this, either in the derived class or it's parent will be
working with an object of class MyCamera not Camera.

Make the return type Camera, then it will work. You will be returning an
object reference of class Camera, but in fact it is an object reference to
an object of class MyCamera. You can then cast it elsewhere as a 'MyCamera'
in the application.

The problem is that you are trying to change the signature of the method
that you are overriding.

[flexcoders] Re: Tutorial zoom in a linechart

[g_odds]

That seems like a reasonable answer, yeah.  I'm doing it using the
min-max setting and it seems to work fine with big datasets. 
Admittedly it all starts to get a bit slow when there are 3 or more
series (each has thousands of data points) but it has other
side-effects that are desirable in my application.

I'll post a link to it when my boss lets me.

Re: [flexcoders] Poor man's PUSH technology (aka reload data using timer)

[Adam Royle]

Hi Mark,

Although I have no experience with this process, the following came to my mind 
when pondering the same issue as yours.

My plan was to keep a history table which tracks all of the updates and 
additions to data (would be simply recording row ids - not the entire row), and 
records a timestamp of when it was changed. This functionality would be coded 
into the server-side code. You would also need a sessions table to track a 
"last synced" timestamp for each user, which would be updated with the current 
timestamp on each sync of the data.

Every 60 seconds or so you would poll the server and it would return all of the 
rows that were either changed, added or deleted since the "last synced" 
timestamp. Once that data is delivered back to flex, simply loop through the 
data on the client side and replace the rows where the id's match, add a row if 
it's new, and delete the row if it's deleted.

You'd probably also want a cron cleaning up the history table periodically, 
depending on how many users there are and how frequently data is updated.

>From my perspective, this would be a pretty fast operation all up. You could

I hope that gives an insight to how I would tackle the problem. Any others want 
to give feedback on this method?

Cheers,
Adam

  Subject: [flexcoders] Poor man's PUSH technology (aka reload data using timer)


  I am building a internal app for my company, where we would eventually
  pursue FDS for it's push capabilities - updating the users view when
  backend data changes.

  Until then, I'm thinking about making a function that will get
  triggered by a timer, e.g. every 60 seconds, it should retrieve data
  from the server and then compare it to the data currently displayed in
  the app [Binded]. Then if data has changed, it should update the
  specific data in the ArrayCollection.

  Any pointers to how I could accomplish this ?

  Im thinking a function "dataTimer" that would call a function
  "getData", that function would then compare each row in the dataset to
  the data currently "in memory" in the app. If there's a difference, it
  would update the data OR completely replace the currently used
  dataset. (only I guess that would make the app flicker?)

  Any help is greatly appreciated.

  Thanks,
  Mark

Thanks Jeff, you're a star.  I'll have a go at this.  

For debugging I have been looking at the Eclipse wtp all-in-one

just downloaded it from Eclipse and was planning on rebuilding today.
 If I turn anything useful up I'll let you know.

[flexcoders] Re: Poor man's PUSH technology (aka reload data using timer)

[oneproofdk]

Hi Adam.

Thanks for your reply - I like your idea about keeping the "pushed"
data to a minimum. My original idea was to get the entire dataset and
then loop through it and compare - your idea is way better.

I'm really in need of some examples of a timer function, and perhaps
some code to make the comparing of data. Anyone that can help me out
there ?

Thanks again,

To anyone at Adobe who's listening:

I'm working on a Flex2 project for Scholastic
http://scholastic.com <http://scholastic.com> and we are
running into a wall in terms of getting our Flex Builder
licenses transfered to the Macintosh platform. We purposely
bought Windows versions knowing that it "wouldn't be a
problem" to transfer the license when the Mac version became
available.

This licensing situation that we and others have experienced
is completely unacceptable. John Dowdel, do you think that
you can help us out a bit, or escalate the issue, as you did
for others experiencing these problems? Or maybe Ted Patrick,
you could let others there know that this is a major issue
for people, and it should be addressed.

Here are the issues that we are currently facing:

1. In order to transfer the license you have to be the
authorized purchaser of the software and Adobe won't accept a
request form the actual end user of the license. To make it
worse Adobe won't tell us who that person is. At a rather
large organization (10,000 + employees) like Scholastic,
finding this "authorized person" is really difficult to do.
2. Even if we do find the person above, we are told that the
process will take five days from the approved request before
Adobe will issue the Mac license number.
3. Currently there's no way for us to extend the trial
version until this is worked out. We either have to install
the trial on another computer or just wait it out.

It's a pitty that such a great piece of software has so many
barriers and red tape to actually use it.

Thanks very much for you attention to this issue.

selectedItem gives you a reference to the node.

 

Probably what you are seeing is because the event is just an Object containing
the xml, so some propeties are not visible.  Cast/convert the result into an xml
object:

var oItem:Object = event.currentTarget.selectedItem;

var xmlItem:XML = XML(oItem)

 

xmlItem will be the node.

I have a Tree that's populated based on e4x XML, which is generated by
PHP from querying the backend. I have a structure like this:










I'd like to be able to double click on an item in the Tree and change
to the necessary viewStack page, which will allow the user to edit the
info. The viewStack page will depend on whether the user clicked on a
project or experiment. 

So far I've tried using onChange(event),
event.currentTarget.selectedItem, which only gives me certain
attributes. I just want to be able to somehow know which XML node
 or  was clicked so I can open the right window.

I've been reading about ItemRenderers, will I need to use one?
I'm familiar with eventListeners but I'm still unsure about how to get
the appropriate XML node based on a click.

Thanks for any help.

Sounds great.
Could you also try and find out if there are plans to
just automate the whole
process ?
It strikes me that converting license betwen platforms
shouldn't really
require a human in the loop, if it's only done once.

[flexcoders] Tree XMLListCollection woes

[durnelln]

Hi all,

I am trying to dynamically build and display a sorted tree, i.e. 
create branches/leaves purely in actionscript.  I *thought* that 
using XML would make this easy due to its hierarchical nature and 
Flex's e4x extensions (which should allow me to easily locate nodes 
in the tree etc without having to code a load of recursion).  An 
example of the kind of structure I am trying to build looks something 
like this:












I am using an XMLListCollection as my tree data provider as this 
provides the sorting capabilities I need to retain the sort order as 
I add new nodes.  As new group objects come in the plan is to turn 
them into XML and add them to the tree in the appropriate location 
(based on their parent attribute).  The groups may come in in any 
order so I make use of the sort ability of the XMLListCollection.

After going round in circles for a couple of days trying to get it to 
work, I found the following article on Peter Ent's blog:

http://weblogs.macromedia.com/pent/archives/2006/10/tree_control_da.cf
m

This has proven invaluable (thanks Peter!).  However I am still 
having problems.  In Peter's example he adds top-level nodes via the 
XMLListCollection's addItem method but child nodes via the 
appendChild method of the underlying XML/XMLList object.  Now, while 
this allows me to build a tree, the child nodes added directly to the 
XML are not sorted according to the XMLListCollection's sort order - 
only the top-level nodes are sorted.

Does anyone know how I can build this tree whilst maintaining the 
sort order?  I do not want to hard-code any particular sort function 
as I want the sort field and direction etc. to remain configurable.

Alternatively, is there any way to add child nodes directly through 
the XMLListCollection object?  It surprises me that a collection 
designed for hierarchical XML data doesn't seem to support this (or 
e4x for that matter).  Why should it be necessary to access the 
underlying XML data directly to add child nodes (causing the sort 
order to break)?

Somebody please help - this is driving me nuts!

Nick.

RE: [flexcoders] Intellectual property or licensing of posted/blogged work

[Matt Chotin]

I believe most of Ely's examples he includes a license or says on his
blog that it's Creative Commons.

 

I don't know what the law states, but I believe most people when posting
will specify rules if they especially don't want you to incorporate.
Full-blown components should include a license, and if not I'd recommend
mailing an author before including their code to confirm that your use
is allowed.  If there is no license included I can't imagine you'd get
in trouble for reading the code in the meantime, but check with your
legal reps to be sure.

and forth I have to do with legal on our own licenses)

Re: [flexcoders] Returning 'this' from an overridden method?

[shaun]

Hi David,

I to am an AS3 novice. Wrote my first(trivial) action script file about 
an hour ago. :)

A couple of ideas. Not sure if they will be of much help to you, but 
incase you hadnt considered them already..

. you could return the value returned by the call to super.
   ie)
   Camera c = super.move;
   //// some local x,y stuff
   return c;

. you could use an interface as the return value. eg) interface ICamera 
would define the move and rotate methods and return an ICamera and your 
Camera classes would implement ICamera.

I realise that these options do not do what you asked for, but you might 
find one of these is an acceptable alternative.

HTH.

Re: [flexcoders] Re: Poor man's PUSH technology (aka reload data using timer)

[Adam Royle]

This is some code I have written for a similar project... It simply runs 
through the dataProvider searching for a matched id. If it finds the id, then 
it replaces the row, otherwise it adds a new row at the end of the 
dataProvider. Since you want to track add, update and delete, you'll probably 
need to specify another field that is returned with the data, such as 
_row_status (0=new,1=updated,2=deleted), and modify the script likewise.



public var dataProvider:ArrayCollection = new ArrayCollection();

public function onUpdateData(result:Array):void
{
 var i:Number, j:Number, row:Object, item:Object, id:Number, found:Boolean;

Re: [flexcoders] Semi-noobie architectural style question

[Troy Gilbert]

That's usually the point of the singleton pattern, that it provides a global
access point for a variable (as well as enforcing a single instance of a
class). Essentially, singleton hijacks a language's type system to use it to
deliver globals.

Of course, in languages like C++ I kinda consider this on par with using
globals and normally prefer something like a monostate object where many
would use a singleton. But, since ActionScript doesn't actually have global
objects, singleton is pretty useful for attaining that.

Perhaps I've missed the guts of your question, but if you create a class
that follows the singleton pattern, you'd have a "getInstance()" static
method. To access your instance you just need to import your singleton class
wherever you need it and then use MyClass.getInstance() to access the
singleton. You'd have to import the class regardless if you wanted to
*access* the singleton, so I'm not quite sure where the disconnect is in
your question...

dual-platform.

[flexcoders] Building the FDS HibernateManager class in Eclipse

Hi,

I am trying to debug the FDS HibernateAssembler.  I have put the

HibernateType
java files into my own package and adjusted dependencies accordingly.  

I am unable to build because of the following problem.  The
HibernateManager.getSession() method contains the following line of code:

if (!syncSession && DataServiceTransaction.getCurrentUserTransaction()
!= null)
syncSession = true;

I get the following two build errors:
1)
The project was not built since its build path is incomplete. Cannot
find the class file for javax.transaction.UserTransaction. Fix the
build path then try building this project
2)
The type javax.transaction.UserTransaction cannot be resolved. It is

I can't find anything which seems to contain the UserTransaction code
or interface.  Anyone know what I need to do to my Eclipse project
dependencies to have this compile?

Re: [flexcoders] is there a way to run Applet in Flash

[Troy Gilbert]

The only way is to fake it by having the surrounding HTML webpage float an
IFRAME over your Flash applet. Same technique folks use for displaying web
pages inside of a Flash app.

I saw a demonstration somewhere of a Flash app that had transparency. I
believe the Flash player allows for a transparent background (I guess that's
how all of those annoying integrated page ads work), so you could probably
float your Flash app over your Java applet as well!

[flexcoders] Resources to Flex Application Architecture articles?

[Private Romeo]

Hi everybody,

 

we are looking for (online) resources related to how to best structure
(larger) Flex applications. Most of the great training and tutorial material
available tends to focus on how to construct more complex controls, how to
implement special effects or how to solve DataGrid/Binding related issues,
however, what we are seeking is material as to potential best practices
about how to structure an Flex app best.

 

Should AS code be used inline primarily? Or is a code-behind pattern a
better choice?

Should we ultimately keep the primary MXML application file small and work
with complex custom controls, or should we keep custom controls usage low?

 

Are there any good technical articles out there? Any links? Any hints?

 

Thanks for your support.

 

 

Re: [flexcoders] Semi-noobie architectural style question

The singleton pattern is dangerous, as are global variables.
The problem is, you can't reuse any of the singleton's users without using
the singleton.

[flexcoders] Object.addEventListener vs.. adding them inline via MXML

[Mike Anderson]

Hello All,

I have a problem, and maybe I am overlooking something here...

What I need to do, is attach multiple functions, to an Event for a
particular Component.

Using inline MXML, this is easy - you just separate out each function,
with a semi-colon and list them one after another.

BUT, I am trying NOT to put my functions within the MXML - I am using
Code-Behind, and I need to add my Event Listeners within the
ActionScript - using the Object.addEventListener() method.

Thing is, how do I add several functions using this type of methodology?
Or can it even be done?

Thanks in advance for any help you can offer regarding this,

Mike

Until then, I'm thinking about making a function that will get

from the server and then compare it to the data currently displayed in
the app [Binded]. Then if data has changed, it should update the
specific data in the ArrayCollection.

Any pointers to how I could accomplish this ?

Im thinking a function "dataTimer" that would call a function
"getData", that function would then compare each row in the dataset to
the data currently "in memory" in the app. If there's a difference, it
would update the data OR completely replace the currently used
dataset. (only I guess that would make the app flicker?)

Any help is greatly appreciated.

[flexcoders] Re: Object.addEventListener vs.. adding them inline via MXML

[dougmccune]

You can make as many calls to addEventListener as you want. So you can
add 2 or more event listeners that get triggered for the same event.

So something like:
myButton.addEventListener(MouseEvent.CLICK, myFunction1);
myButton.addEventListener(MouseEvent.CLICK, myFunction2);
myButton.addEventListener(MouseEvent.CLICK, myFunction3);

All three of the above functions would get called when the event
triggers. You can remove each of these separately as well by using
removeEventListener and specifying the particular function you want
removed.

[flexcoders] Re: Returning 'this' from an overridden method?

[dougmccune]

Just from first glance I'd suggest not following the design pattern of
returning the object from the function like you're doing. It seems
like the only reason you're doing it is to make it so you can write a
bunch of statements all on one line. In terms of someone else reading
your code, I think it would make a lot more sense if they saw this:

camera.move(10, 12);
camera.rotateX(45);
camera.rotateY(90);

It turns 1 line into 3 lines, but I think it's far less confusing and
this follows the same design pattern that most other Actionscript
classes follow. Methods like move, rotate, etc are used often in
various classes and usually they do what they're supposed to do and
return void. In my experience I've never really seen an OOP class that
returns itself very much.

So that's not a direct answer to your question, merely a coding
suggestion.

I will now pass myself off as a legal expert despite the fact that I
haven't attended law school...so anyone with authority should overrule
my opinion.

Generally speaking, if the owner (which is usually the author) publishes
the code on the web, then you are allowed to look at it.  They showed it
to the public, the public gets to see it.  (It's the same theory that
while a billboard is still copyrighted, you can't tell people not to
look at it.)  You can even tell other people about it and where it is
(although you can't necessarily give them a copy yourself). 

As far as using it in your own projects, that depends entirely on the
license.  Sorry, there is no standard.  However, many blogs and most
adobe products/solutions/projects (including many you mentioned) are
pretty explicit on what you can do.  I assume if you publish things on
this list then you're ok with people using them as they see fit, but
that's a personal assumption, not a legal one.  Maybe there was
something in the signup that i missed which said this list is in the
public domain, but I don't remember it.

RE: [flexcoders] Re: Object.addEventListener vs.. adding them inline via MXML

[Mike Anderson]

Hey Doug,

Well, that's simple enough.  Probably so simple, that I simply
overlooked doing it that way.

Real quick, would it be possible to also do it this way?

Object.addEventListener( "click", [funct1, funct2, funct3] );

I know I could just try it, but from a methodology point of view, it
would be nice to know if this was a valid way to do it.

Thanks!

You can make as many calls to addEventListener as you want. So you can
add 2 or more event listeners that get triggered for the same event.

So something like:
myButton.addEventListener(MouseEvent.CLICK, myFunction1);
myButton.addEventListener(MouseEvent.CLICK, myFunction2);
myButton.addEventListener(MouseEvent.CLICK, myFunction3);

All three of the above functions would get called when the event
triggers. You can remove each of these separately as well by using
removeEventListener and specifying the particular function you want
removed.

Re: [flexcoders] Re: Object.addEventListener vs.. adding them inline via MXML

[Michael Schmalle]

Object.addEventListener( "click", [funct1, funct2, funct3] );


No,

1. as3 is strongly typed which means the method expects a function when it
is getting an array.
2. addEventListener wouldn't even know what to do with an array.

You could, if you had your own subclass override addEventListener to do that
but, you could also just create a stack of functions in an array if they
were all going to the same event and loop through them to save code lines.

It's personal choice when you get to this point.

Re: [flexcoders] Re: Object.addEventListener vs.. adding them inline via MXML

[Doug McCune]

Nope, I think the second parameter must be a function, trying to pass an 
array of functions should fail.


Also, just a note: it's better practice to not use the string of the 
event listener like "click" but rather the variable like 
MouseEvent.CLICK. They really do the exact same thing in practice, but 
it's possible that within MouseEvent the click event could be renamed in 
a future release to something like "mouseClick" and then your code 
wouldn't work.

[flexcoders] Validator: disable active validator

[fritzdimmel]

Hi!
I've a form with many controls (TextInputs, ...) to validate.
Everything works fine but I can't figure out, how to accomplish this:
I have, let's say, a TextInput, and the validation for this returns
false. The textinput gets a red border.
Now I want to have a possibility to disable the validator temporarliy.
So that the red border disappears until I'm re-enabling the validator.

How can I do this?
By setting Validator.enabled to false the red border (+ the error
message) still exists.

Thanks for any hints!

RE: [flexcoders] Re: Tutorial zoom in a linechart

Hi Graham. That would work just fine.  It forces the chart to do some
extra work, b/c it still has to process those out of bounds data values
far enough to decide they're out of bounds.  So be alert for performance
issues. But other than that, it should work fine.

Re: [flexcoders] Re: Object.addEventListener vs.. adding them inline via MXML

could be renamed in a future release to something like "mouseClick" and

then your code wouldn't work.

Or even worse, you write "cllck", and then for days even months, you think
your app isn't working or 'works' a certain way. Come to find out the event
wasn't even getting captured. :)

This is plain ole preventative maintainence.

That is the worse case for me, renaming events is small potatoes to that
error. ;-)

[flexcoders] 2nd datagrid - no headers, wrong size

[Mike_Robinson_98]

I've been spending a lot of time trying to overcome this issue without
any success. Hopefully someone out there has a suggestion.

I have datagrid within a vbox in a component. The grid takes up as
much space as is available (height='100%').

There is another state which does the following:
1) reduces the height of the 1st datagrid to a fixed value (344)
2) adds a 2nd datagrid (height='124') into the vbox as the lastchild.

The problem is when the state gets switched and the 2nd datagrid gets
added..
1) the headers are missing
2) the requested size is not honored

When looking at the state in design mode, the headers are present and
the size of the 2nd grid is correct.

Has anyone run into issues similar to this? Any resolutions? The code
is rather long, but I will post it if anyone is interested.

Thanks

RE: [flexcoders] Returning 'this' from an overridden method?

[Sho Kuwamoto]

The short answer is that there is no way to do what you want for the
time being. 
 
What you are looking for is a language feature called "covariant return
types". In certain languages (C++, Java) you can have your subclass
redefine the type that is returned by a method.
 
This would be a great thing to get into the AS language, but it is not
there now. There are further wrinkles when you consider how you would
extend properties in a similar way (I wrote about the issues at
http://kuwamoto.org/2007/01/22/covariant-property-types/).

Subject: [flexcoders] Returning 'this' from an overridden

Please pardon this simple-minded question from an AS3 novice.

My base class often returns 'this' from methods which makes it 
convenient to write code like:

camera.move( 10, 12 ).rotateX( 45 ).rotateY( 90 );

The problem comes when code extends the base class and overrides
one 
of these functions. The compiler insists, correctly, that the
return 
type of an overriding function must match the one in the base
class. 
What I want to do is return the 'this' object that is of the
type of 
the derived class. Is this possible?

The following is a contrived example to demonstrate. It won't 
compile because the overridden function in the derived class
wants to 
return a type of MyCamera rather than Camera:

public class Camera
{
var x:int = 0;
var y:int = 0;

public function move( x:int, y:int ) :Camera
{
this.x += x;
this.y += y;

return( this );
} 
}

public class MyCamera extends Camera
{
override public function move( x:int, y:int ) :MyCamera
{
super.move( x, y ); 

if( x < 0 ) x = 0;
if( y < 0 ) y = 0;

return( this );
} 
}

*Subject:* [flexcoders] Returning 'this' from an overridden method?

 Please pardon this simple-minded question from an AS3 novice.

My base class often returns 'this' from methods which makes it
convenient to write code like:

camera.move( 10, 12 ).rotateX( 45 ).rotateY( 90 );

The problem comes when code extends the base class and overrides one
of these functions. The compiler insists, correctly, that the return
type of an overriding function must match the one in the base class.
What I want to do is return the 'this' object that is of the type of
the derived class. Is this possible?

The following is a contrived example to demonstrate. It won't
compile because the overridden function in the derived class wants to
return a type of MyCamera rather than Camera:

public class Camera
{
var x:int = 0;
var y:int = 0;

public function move( x:int, y:int ) :Camera
{
this.x += x;
this.y += y;

return( this );
}
}

public class MyCamera extends Camera
{
override public function move( x:int, y:int ) :MyCamera
{
super.move( x, y );

if( x < 0 ) x = 0;
if( y < 0 ) y = 0;

return( this );
}
}

Re: [flexcoders] Re: Object.addEventListener vs.. adding them inline via MXML

[Doug McCune]

Mike,
Looks like you're speaking from personal experience :)
From now on I'll make my custom components dispatch "click" and "cilck" 
and "cllck" and "clik" etc etc. The "google suggest" approach to event 
dispatching.

Or even worse, you write "cllck", and then for days even months, you 
think your app isn't working or 'works' a certain way. Come to find 
out the event wasn't even getting captured. :)


This is plain ole preventative maintainence.

That is the worse case for me, renaming events is small potatoes to 
that error. ;-)


Peace, Mike

Nope, I think the second parameter must be a function, trying to
pass an array of functions should fail.

Also, just a note: it's better practice to not use the string of
the event listener like "click" but rather the variable like
MouseEvent.CLICK. They really do the exact same thing in practice,
but it's possible that within MouseEvent the click event could be
renamed in a future release to something like "mouseClick" and
then your code wouldn't work.

Hey Doug,

Well, that's simple enough. Probably so simple, that I simply
overlooked doing it that way.

Real quick, would it be possible to also do it this way?

Object.addEventListener( "click", [funct1, funct2, funct3] );

I know I could just try it, but from a methodology point of view, it
would be nice to know if this was a valid way to do it.

Thanks!

You can make as many calls to addEventListener as you want. So
you can
add 2 or more event listeners that get triggered for the same event.

So something like:
myButton.addEventListener(MouseEvent.CLICK, myFunction1);
myButton.addEventListener(MouseEvent.CLICK, myFunction2);
myButton.addEventListener(MouseEvent.CLICK, myFunction3);

All three of the above functions would get called when the event
triggers. You can remove each of these separately as well by using
removeEventListener and specifying the particular function you want
removed.

[flexcoders] RemoteObject over HTTPS / SSL

[Piotrowski, John]

I have been working on this for a few days and I am stuck.  I have an
application that is using the Cairngorm Framework and I create 2
RemoteObjects.  I got these RemoteObjects to work by relying on the
default services-config.xml file on the server (which I don't have
access to) and by simply creating a Basic Project in Flex Builder 2 with
no compiler options and defining the endpoint
(http://SERVER/flex2gateway), destination (ColdFusion), and source (dot
path to cfc).

 

Now here is my problem.  One of my RemoteObjects needs to be over SSL
since it is handling the authentication for the application while the
other one does not and we would like to access the application by just
going to the standard http address (I was using dummy data when logging
in before since it wasn't over HTTPS).  We achieved this in the Past in
Flex 1.5 by creating the RemoteObject with the Protocol attribute set to
https and it was working in 1.5.  Since Flex 2 no longer supports the
protocol attribute, I tried changing the endpoint to
https://SERVER/flex2gateway.  I build the project and then open the HTML
file (in IE) the compiler creates in the bin folder and I get an error
Send Failed, Channel.Connect.Failed error NetConnection.Call.Failed:
HTTP: Status 500.  I get this error when trying to load the html or SWF
directly over HTTP and HTTPS and also in Firefox.

 

So, a co-worker sent me this link
(http://www.simb.net/client/index.cfm/2007/2/2/How-I-create-a-Flex-Proje
ct-with-ColdFusion) where it says to use a local services-config.xml
file and add the compiler option.  So I got one of the server admins to
send me the file and I created libs/services-config.xml in my project
and added -services "libs\services-config.xml" to my compiler arguments.
I first tried the normal http remoteobject method and it works just like
before, then I changed the endpoint to https like I did before using the
server's config file and I get the same behavior as before.

 

Next, I read that I probably have to create a channel definition for the
SecureAMFChannel.  So edited the current AMF channel definition to read:




https://{server.name}:{server.port}{context.root}/flex2gateway/";
class="flex.messaging.endpoints.SecureAMFEndpoint"/>

  

false

false



  false



  

  

 

I also made sure to change the name in the channels tag in the
destination declaration of the xml file.  Then I changed the endpoint in
my remoteObject declaration to https://SERVER/flex2gateway and I still
get the NetConnection error when loading the app over both http and
https and in both IE and FF.  Again ideally, we want to have 2 channels
one over SSL and one standard, but I can't even get SSL only to work.

 

So at this point I am thinking there must be something on the Server
that needs to be changed but I am not sure what to tell the admins to do
and no one else at my work is ready to publish a Flex 2 so I am the
first person to attempt to solve the SSL problem.

 

Any thoughts and thanks,

John

This leads me to another question - how would these dynamically-

In Flash, I was able to use the _parent pronoun from within the

[flexcoders] basic exception handling

[dantmcgowan]

All,
  When I am catching exceptions the catch seems to be ignored and the
actionscript error window pops up. For example if I have a simple
service like this:

http://example.com/someservice/";
useProxy="false"
method="GET">

And I have a try catch block like this with one statement inside. If I
comment out this statement no errors...so I know this statement is
causing the error:

   
try {
simpleService.send();
}
catch(errObject:Error) {
trace(" "+errObject.message);
}

The scenarios that throw errors (for example TypeError: Error #1034)
opens the actionscript error window and the trace does not appear.
What do I need to be doing so the exception is consumed in the catch
and no error window? Thanks,

Dan

RE: [flexcoders] basic exception handling

[Peter Farland]

Right, the requests made by HTTPService are asynchronous... so you have
to wait for events to be dispatched some time later. Any errors that
occur prior to actually sending the request are typically caught and
dispatched as fault events too so there shouldn't be a need for a
try/catch.
