[flexcoders] Re: From DataGrid to Clipboard and Excel

[Tony Obermeit]

This isn't exactly what you asked about but it's close.

I use the method below to copy selected rows to clipboard.  In this use I
have a tab character to separate the columns, elsewhere I provide the user
the choice between tab and comma with a separate dialog.

private function syncCopyToClipboard():void
{
// Separator used between Strings sent to clipboard
// to separate selected cells.
var separator:String = "\t";
if (syncComma.selected) separator = ",";

// The String sent to the clipboard
System.setClipboard(" ");
var dataString:String = "";
var n:int = dgSyncGroupMembers.selectedCells.length;
if (n == 0)
{
Alert.show("You have not selected any rows, to select
all rows: click on the first row, scroll to the bottom and shift click on
the last row. Otherwise, select specific rows before you press the copy to
clipboard button.");
}
for (var i:int = 0; i < n; i++)
{
var cell:Object = dgSyncGroupMembers.selectedCells[i];
var data:Object =
dgSyncGroupMembers.dataProvider[cell.rowIndex];
var nameField:String =
dgSyncGroupMembers.columns[0].dataField;
var valuField:String =
dgSyncGroupMembers.columns[1].dataField;
dataString = data[nameField] + separator +
data[valuField] + "\n" + dataString;
}

// Write dataString to the clipboard.
System.setClipboard(dataString);
}

[SPAM] [flexcoders] Re: how to open pdf, word file using flex

[Tony]

Hello!

I have come up with another solution to view .pdf and .doc files. I have 
described it in my blog: 
http://tgeorgiev.blogspot.com/2010/05/viewing-word-documents-with-flex.html The 
idea is to convert the .doc to .pdf, and the .pdf to .swf using pdf2swf and 
then you could write your own logic to display the file or use a library like 
FlexPaper.

Best,
Tony Georgiev

[flexcoders] re: Flex and Reporting

[Tony Obermeit]

If you have details of where to download this, I'd appreciate you forwarding
them to the list.  I found the code in google code but it seemed I had to
download each .mxml file individually.  I'd like to download the entire
source as one bundle.

I'm keen to use this as it appears to answer the printing questions I've
posted recently.  If anyone has working examples of printing a textarea
using FlexReport, I'd love to see the code.

Regards

Tony

You might wonna look at this:

I have not used it yet, but I am planning to use it for my current app.

[flexcoders] Re: Print examples?

[Tony Obermeit]

Thanks Rick, that helped.  I had not been adding the argument to addObject
that specified a scaling. (In this case i used MATCH_WIDTH).

However, I'm printing a text area and the scaling didn't do what I expected,
it just truncated anything that was wider than the page width.  What I'm
hoping for is a component that will wrap the text within a paragraph
according to the page width.  And be able to change / specify a single font.

Any further advice greatly appreciated.

Tony

If you want to print a sub-set of you text... You are going to need to
select the appropriate text ­ transfer to a temporary container and use the
temporary container as an argument for the PrintJob.addObject(). Remember
that in order to print what you see ­ you must see what to print. This is
essentially the context of the first paragraph in livedocs...

[flexcoders] Printing simple documents in flex

[Tony Obermeit]

I need to generate a fairly basic document in flex that is easy for the user
to print.  I don't consider generating a PDF to a new window / tab to be
easy in this context.

I've found reference to an open source api: Flex Report (
http://www.kemelyon.com/bts/) but the site hasn't been updated for a while.
The examples show there look quite good.

What I'd like to be able to do is create a document, add text to it
(selecting an overall font and size optionally), have the text automatically
wrap if the paragraph extends beyond the page margins and have a button that
says "print".

Any / all advise appreciated

[flexcoders] re: Books - Flex

[Tony Obermeit]

2 books that I've found to be a big help are:

Adobe Flex, Training from the Source, by Adobe Press

Programming Flex, O'Reilly, Kazoun and Lott

I basically learned flex by going through the Training from the Source book,
it teaches you, sort of tutorial style, how to build a multi media shopping
cart application

The programming flex book is useful as a more detailed reference

Also there is much free online documentation from Adobe themselves that is
great

http://coldfusion-in-idea.blogspot.com/

There is a plug in for cold fusion for IntelliJ.  I also read on another
blog that the developers who work on cold fusion mostly use Intellij.  Not
sure if that is true or not.

I use Intellij for java / jsp / html / groovy and am thrilled with it.
Haven't tried it yet for flex but am tempted to.  What is missing in flex
builder for me is a pane that shows me the list of methods in my 
component.

[flexcoders] flex validator for form items dependent on each other

[Tony Obermeit]

I've used the  component and extended it with my own action
script code.  This has worked quite well for me when validating a single
form item.

Now I have two items that are dependent on each other.

Soft quota ( values allowed 3, 7, 10)

Hard quota (values allowed 3, 7 , 10)

But, the hard quota must always be equal too or larger than the soft quota.
I'd like to implement this in a validator.  How do i reference other items
in a validator?

thanks

[flexcoders] Newbie HELP

[Tony]

Ok.  I have been working through a Friends of Ed book called
Foundation Flex for Designers.  In chapter 8, the idea is to build a
external xml file controlled photo gallery.  Screen will be split
horizontally with one side being thumbnails of the larger pictures
stored externally to the application.  The other side (right side) is
supposed to display the targeted picture in full dimensions. I have
not got to the right side yet.  I am to the point where thumb nails
should be showing up in the thumbnail pane.  But I keep getting an
error upon runtime out of flex.  Can any one help???  I have put a zip
file in the files area of this group that contains a folder for the
picture assets and xml file plus all the flex files.  Can someone tell
me what I did wrong??

The next step will be to create a basic css file.  But my thumb nails
should still be showing up in the pane (or is it "pain").

respectfully,

Re: [flexcoders] Re: Styling List ItemRenderers

[Tony Fendall]

What I normally do, is extend the list component and
add a bunch of public properties or styles to it.
eg. public var titleColor:uint;

Then in my item renderer class, I override the
commitProperties function, and in there grab the
properties and styles I need from the list.
eg.
var tmp:CustomList = this.owner.parent as CustomList;
this.setTitleColor( tmp.titleColor );

Hopefully that makes sense.

One other thing you might want to do if you use this
approach, is to cause the item renderers to re-request
their styling information if the styles change at
runtime. This can be done by adding a function to your
CustomList like this one (note, this funciton came
from inside a custom DataGrid of mine, but should be
easy to translate to other list types)

public function invalidateItemStyles():void
for (var rows:int = 0; rows < listItems.length;
rows++)
{
var rowArray:Array = listItems[rows];

for (var cols:int = 0; cols < rowArray.length; cols++)
{
var colItem:UIComponent = rowArray[cols] as
UIComponent;

if (colItem)
colItem.invalidateProperties(); // refresh
}
}
}


Hope that helps

[flexcoders] apply style sheet to as3 - only application?

[Tony]

hi there.

i can apply a stylesheet no problem, to a mxml application.
however, in an as3 only application, i cant seem to figure out how
to do this.

i can TextFormat using a stylesheet, when its text, no problem.

just cant figure out how to do it for the whole app.  mainly i want a background
gradient and some background alpha changes.

thanks for any help

[flexcoders] Re: Recovering from videodisplay errors? [Solved]

[Tony]

Ok, Here is the solution:
if (videoDisplay.state=="connectionError"){
  videoDisplay.close();
}
videoDisplay.play();

You could also listen for stateChange on the player checking for a
connection error and solve the issue at that time.  I think that is
the best way to go.

Anyone ever able to answer this?
I am getting the dreaded connectionError! and cannot recover from it also.

I can capture the error just fine. One the

Anyone have a solution for this one.

Re: [flexcoders] Flickr: Sandbox issue with unavaiable.gif

[Tony Alves]

Interesting, because it does have a cross domain.
http://l.yimg.com/crossdomain.xml

Maybe it using http://l.yimg.com/www.flickr.com/ 
<http://l.yimg.com/www.flickr.com/images/photo_unavailable.gif> as the 
root of the domain.

Try to set up the |loadPolicyFile()| method for the above crossdomain.

Re: [flexcoders] Converting app to use modules

[Tony Alves]

Scott,
I may get corrected on this one, but take it for what it is worth.
I thought you had to create an instance of manager classes in the main 
application even if you did not use them there.

So you would put something like the following into your MainView.mxml :
private var dragManager:DragManager;

I do this out of habit, but not sure if it solves anything.

HTH,
Tony

This is one of the most fun I have had on flexcoders in a long time.

Gmail does help with a lot of the issues, that is why I changed to a

[flexcoders] error in AIR application

[Tony Alves]

I am getting an error on a line in my AIR application:
ReferenceError: Error #1069: Property _bindings not found on 
components.EmployeeListPanel and there is no default value.
   at 
mx.binding::BindingManager$/setEnabled()[E:\dev\flex\sdk\frameworks\projects\framework\src\mx\binding\BindingManager.as:65]


I am sure this is a timing issue, but it works using it in a Flex 
builder 2 application.  Any thoughts?
I am thinking that in the Air application all components are loaded 
immediately.  Just a guess.

I am using Flex 3 Beta 2

   /**
*  Set isEnabled for all bindings associated with a document.
*
*  @param document The document that contains the bindings.
*/
   public static function setEnabled(document:Object, 
isEnabled:Boolean):void

   {
*if (document && document._bindings)*
   {
   var bindings:Array = document._bindings as Array;
  
   for (var i:uint = 0; i < bindings.length; i++)

   {
   var binding:Binding = bindings[i];
   binding.isEnabled = isEnabled;

That is off the board.  Do you think it will be possible to get rid of

Hi,

I also found another workaround for the rollover. I added a timer
to the dispatch method and it will wait the determined amount of
milliseconds before firing the open event.

This improves usability greatly.

Hi,

I slapped this together. There are a lot of things that could be
improved but, you be the judge.

One thing is it doesn't quite 'slide' like the apple example does
but, that would be another component that used a canvas and funky
depth management.

Plus whenever you use rollOver, there are bound to be issues.
MouseDowns are much better but, this uses rollOver. For the time I
put into it about 1 1/2 hours it's close.

The Image is actually the content that could be whatever you want.
The gray part is the custom titleBar that was made with an inline

You can put "id" in the "Value Name" TextInput, then type the numeric

This allows a change of the column in the ArrayCollection you will be

I have tried the method you suggest, but it did not act the way I

I extended the datagrid to find the value I am looking for based on the 
value and the name of the value.  Let us know if you see a disadvantage 
to doing this.

Re: [flexcoders] Re: NEW FLEX WEBSITE: ManureMail.com

[Tony Alves]

Randy,

I second that sentiment!  Flex kicks ass!
I am still struggling with the 100% Flex site structure.  Will it be too 
much out of the gate?  Will users get turned off everytime they see a 
site using flash/flex, because so many developers are going to use it 
when there was no need for it?  These are the unknowns.
I think your site is a good example of having a Full Flex solution.  
Little site content, lots of data centric needs (eCommerce).
Oh, the struggles of a web application developer.

Re: [flexcoders] Does anyone know what the cause of this problem is

[Tony Alves]

If using Flex Builder:
ctrl-shift-F
search the whole workspace for "_accountID".

Re: [flexcoders] Making custom class data global

[Tony Alves]

Don,

I currently use a similar method of authenticating my users in Flex and 
store user access information.
My method might not be the best, but it works well for my configuration. 
I am using modules and other components that check login information.
Here it is:
I store all user data in an object that is a singleton.
I instantiate this class in the main application on initialization and 
set the data once there is a valid login.  I then access this class in 
any of my modules, components, etc throughout the application.  I have 
no problem with the binding, so far.
When the class is instantiated, you always go after the data in a 
getInstance method for the users data.  Every component now sees the 
same exact reference data.

I use this method, because my Flex applications may be authenticated 
already in another Flex application or Web Form and I have an 
initialization process in each application that checks for 
authentication the same exact way.  I extended Application to 
authenticate a user.  The process checks for a valid user login.  If the 
user is logged in already, a call is made to populate the user data into 
the singleton.  If not, the application loads a login module. Once a 
valid login is accomplished, the user data is populated.

There are plenty of examples out there of using a singleton class if you 
do not have one.

Regards,
Tony

[flexcoders] Using [Event...] in Custom Classes

[Tony Alves]

Jurgen,
I believe the problem here is that you are setting up a metadata tag on 
your class in actionscript which is not needed and I think it was said 
that Event meta tags are ignored by the compiler in ActionScript 
classes.  Someone here can clear that up for us.  I am not sure why, but 
it is only needed on MXML when setting up an event.  Because you are 
extending your class as an EventDispatcher, you only just need to 
dispatch the event you are setting up.

package components
{
import flash.events.Event;
public class MyClass extends EventDispatcher
{
public static const MY_EVENT:String = "myEvent";
   
private function myFunction():void
{
dispatchEvent(new Event(MyClass.MY_EVENT));
}
}
}

THEN you can instantiate a MyClass variable and add an event listener:
var mine:MyClass = new MyClass();
mine.addEventListener(MyClass.MY_EVENT,someHandlerFunction);

The code assist is trying to show you the events on the event dispatcher 
and there really is just the two by default (activate and deactivate).
Don't ask me why though.  I always set up my Event types as constant 
vars on my class, so I know I need to access them off my class name.
This should work the same way for custom Events also.

Maybe an adobe flex expert can explain this better than I, but that is 
my understanding.

Regards,
Tony

P.S. ( you were borrowing (some call it hijacking) another thread and I 
think it was getting missed.)

Jurgen Wrote: >>>>>>>>>>>>>>>>>>>>>>>
There seems to be an issue using a custom class' event metadata in an
addEventListener statement. Here is an example:

package com.example
{

import flash.events.EventDispatcher;

[Event(name="myEvent", type="flash.events.Event")]

public class MyClass extends EventDispatcher
{

// class code

private function myFunction():void
{
dispatchEvent(new Event("myEvent"));
}

}

}

When using an instance of that class and creating an addEventListener in
code (not using it with MXML tags) Flex Builder's code assist lists the
event, but splits it apart and shows it as Event.MY_EVENT.

That of course throws a compiler error.

Is this by design and how would we work with an event in a custom class
using the [Event...] metatag?

I haven't checked to see if this is different with a custom event. I'll
check on that next, but I wanted to see if anyone has run into this
problem before.

Thanks,

Jurgen

[flexcoders] Re: Overriding getters/setters getting compile error

Sorry, if it sounded like I meant it was a scoping problem. They just
cannot have the same name for compiler purposes.  I was just pointing
out that you had duplicate property names. Coming from the .NET world
this is very normal for me.  I should have just said "You have a
duplicate property name problem" :)

[flexcoders] Re: user configuration file

[Tony Obermeit]

For the flex application, the configuration of which URLs to access  
etc can come from a single, server side configuration.  That can be  
done however you need to with your server side language.  To pass  
these configuration values in to your swf file, you need to  
dynamically generate the html which calls your swf.  Make sure the  
generation creates javascript variables which have the configuration  
values.  The flex application can read these values. I don't recall  
the syntax to do this but there have been relatively recent posts  
that show how.

[flexcoders] Re: User authentication

[Tony Obermeit]

I've been following this thread with great interest as I need to  
solve same issue.

My understanding is we can set credentials on the HttpService but I  
don't want this to be the username / password entered by the user,  
that is a separate layer.  I want to protect my calls to the  
HttpService even if the user has not logged in, an "anonymous"  
access.  But I don't see how a HTTPS connection solves my issue.   
HTTPS will ensure the communication between the client (browser /  
flash) and the http server is encrypted but it doesn't control what  
the client does with the data it gets back.  If I can implement the  
hashing or encryption logic mentioned in flash, doesn't that mean a  
hacker can implement the exact same code in javascript and then be  
able to access the same secure http call my flash application can?   
If the swf file includes the key used to hash / encrypt, then the swf  
file could be decompiled or otherwise inspected to find the key?

Thanks again guys for perservering with this thread.

Thanks again for your help Ray and Peter..

I am actually a little lost. All I want is to guarantee that the user  
name
and password that will go from Flex HTTPService to my JSP web-service  
will
not be intercepted. And I'm also lost about how will I maintain the  
session
with the HTTPService. Cookies dont seem to be possible, URL rewriting is
possible mas I'll have to see how will I do that. At the moment of the
login, my service will have to pass me a key or something like that. (as
someone already mentioned) That I will use along with the other  
services...
I'm lost. lol

[flexcoders] Re: Flex Security Best Practices

[Tony Obermeit]

I'm interested in anything you find

One of the solutions I'm looking for is something that lets me set  
credentials on the HttpService object without hard coding the  
credentials in my swf file.

Mobile 5.0 and Flashlite 2.1

is there a way to convert a flex app's swfs into flashlite apps?

or am i simply crazy?

[flexcoders] Flex access to cookies

I need to access the cookies already created in the browser in order  
to determine if the user has been authenticated using oracle single  
sign on.

1.  Which flash object / class do I use to access the cookies?

2. Anyone have tips / code to share that they've used to authenicate  
user with oracle sso?

[flexcoders] Slideshow problem: Preloading a hidden image resets its visible property

[Tony Wu]

Hi I am creating a slideshow that display images from a RSS feed. It has
two images overlapping each other.  The logic is simple: When one image
is shown, I preload the next image in the hidden second image, then I
flip them on a timer with fade in/out effects.

The problem I have is: For the hidden image, although the image.visible
property is set to false. when preloading a new image 
image.load(newImageURL), the image will become visible (not hidden) -
although I can reset it to invisible right away, however, this produce a
quick screen flicker. I guess when loading anew  image,  Flex is
recreating a brand new object while discarding original properties.

How can I keep the image hidden? Or is there a better approach with
doing fade in/out in picture slideshow?

Thanks for your time and efforts.

RE: [flexcoders] Flash 8.5 Release -- Vote of Confidence

[Tony Pujals]

Hey, this wasn’t a troll! ;-)  No
one has any insight or opinion on this…?  Let me add that I’m extremely
pleased with beta 2 and at this point I’ve pretty much made up my mind to
use it for the project, but if Flash 8.5 ends up being significantly late (eg,
later than July), I will probably be roasted over coals…. So … if
anyone has any reason to believe that I’m being way too optimistic
(foolish), I’d really like to hear sooner than later.

I want to follow up and mention that I'm aware
FileRerence before I get
a lot of suggestions to use it ;-), but I had
other reasons why I wanted
to create a form within an iframe.

In any case, I'm particularly intrigued by the
idea of displaying
content in an iframe managed by an mxml component,
as C. Conraets & B.
Deitte have demonstrated in their articles. What I
did have working of
my page preview inside of a panel looked pretty awesome
-- but for now I
have to live with opening a separate browser
window.

I also forgot to mention that the FireFox
version does occasionally
display the iframe -- flickering like it's
updating umpteen times per
second.

Subject: ExternalInterface and IFrame

I wanted to create an "dialog" as an
html form in an iframe rather than
opening a separate browser window for uploading
image files. I also
wanted to create an html page preview using an
iframe as well.

I spent an entire Sunday working at this and none
of my efforts have
succeeded satisfactorily. I researched the web and
came across Crostophe
Coenrats' article, and after modifying it for Flex
2 / AS3, I still
didn't get no satisfaction. A little more research
and I found Brian
Deitte's update for AS3 as well and tried his
solution, and still no
joy. I tried every variation I could think of,
working with fscommand,
navigateToURL, and of course, ExternalInterface.

It appears that it doesn't matter which strategy
you use. In all cases,
I came close to achieving what I wanted. The
problem even in the
simplest case is that clicking in the iframe, then
clicking outside of
it, causes the iframe to disappear until something
causes the iframe to
refresh with IE, and nada for FireFox (I'm using
IE 6 and FireFox
1.5.0.1 on Windows XP SP2, and of course, Flash
8.5).

Here's a distilled set of the code primarily based
on Conraets/Deitte's
work:


Test.mxml
=

http://www.adobe.com/2006/mxml"
layout="absolute">

  
    http://" />
    
    
  
  
  
    
  




iframe.js
=
function loadIFrame(id, uri) {
    var f =

[flexcoders] RE: ExternalInterface and IFrame

[Tony Pujals]

I want to follow up and mention that I'm aware FileRerence before I get
a lot of suggestions to use it ;-), but I had other reasons why I wanted
to create a form within an iframe.

In any case, I'm particularly intrigued by the idea of displaying
content in an iframe managed by an mxml component, as C. Conraets & B.
Deitte have demonstrated in their articles. What I did have working of
my page preview inside of a panel looked pretty awesome -- but for now I
have to live with opening a separate browser window.

I also forgot to mention that the FireFox version does occasionally
display the iframe -- flickering like it's updating umpteen times per
second.

I wanted to create an "dialog" as an html form in an iframe rather than
opening a separate browser window for uploading image files. I also
wanted to create an html page preview using an iframe as well.

I spent an entire Sunday working at this and none of my efforts have
succeeded satisfactorily. I researched the web and came across Crostophe
Coenrats' article, and after modifying it for Flex 2 / AS3, I still
didn't get no satisfaction. A little more research and I found Brian
Deitte's update for AS3 as well and tried his solution, and still no
joy. I tried every variation I could think of, working with fscommand,
navigateToURL, and of course, ExternalInterface.

It appears that it doesn't matter which strategy you use. In all cases,
I came close to achieving what I wanted. The problem even in the
simplest case is that clicking in the iframe, then clicking outside of
it, causes the iframe to disappear until something causes the iframe to
refresh with IE, and nada for FireFox (I'm using IE 6 and FireFox
1.5.0.1 on Windows XP SP2, and of course, Flash 8.5).

Here's a distilled set of the code primarily based on Conraets/Deitte's
work:


Test.mxml
=

http://www.adobe.com/2006/mxml";
layout="absolute">

  
http://"; />

f.style.visibility = "visible";
top.frames["testFrame"].location.href = uri;

RE: [flexcoders] Extending MXML components (change from 1.5 to 2)

[Tony Pujals]

Thank you very much for the response –
you have no idea how timely it is for us internally. I’ve been a strong
advocate for Flex 2. Unfortunately, I can’t say more on a public list,
but I would be very interested in having a private dialog about some of the barriers
that are affecting our direction.

 

Best regards,

 

Tony

Extending MXML components (change from 1.5 to 2)



 



Tony,

 

Yes, we absolutely intend to continue supporting extending MXML
with MXML, with the constraint that only one set of children be specified
anywhere in the chain of derived components or the component instantiation. 

 

What you’re seeing is a bug in beta 2 – the framework
incorrectly raises the “multiple sets of children in base and derived
components” error in cases where the superclass (A.mxml in your example)
in fact has no children.

 

This will be fixed for beta 3; the workaround in beta 2 is to
insert the following  code into the superclass, e.g. A.mxml:

 



/**

 * 
This namespace is used for undocumented APIs -- usually implementation

 * 
details -- which can't be private because they need to visible

 * 
to other classes.

 * 
APIs in this namespace are completely unsupported and are likely to

 * 
change in future versions of Flex.

 */

namespace
mx_internal = "http://www.adobe.com/2006/flex/mx/internal";

 

override
mx_internal function
setDocumentDescriptor(desc:mx.core.UIComponentDescriptor):void

{

  
if (mx_internal::_documentDescriptor &&
mx_internal::_documentDescriptor.properties.childDescriptors)

  
{

 
if (desc.properties.childDescriptors)

 
{


throw new Error("Multiple sets of visual children have been specified for
this component (base component definition and derived component
definition).");

 
}

  
}

  
else

  
{

 
mx_internal::_documentDescriptor = desc;

 
mx_internal::_documentDescriptor.document = this;

  
}

}

In Flex 1.5,
you could create an MXML component and then extend it with another custom
component. For example, this would work:

 



A.mxml









 

 



B.mxml





   




 

 



Test.mxml





   




 

 

 

 

How was this
useful? Well, for example, for an HTML page editor, we had an Element.mxml
component subclassed by ImageElement.mxml and TextElement.mxml.

 

This does not
work with any of the Flex 2 alpha/betas. Flash 8.5 displays this diagnostic:

 

Error:
Multiple sets of visual children have been specified for this component (base
component definition and derived component definition)

It’s
not that the error message isn’t clear, per se, but since this is
different behavior, I’m curious …. Can you only extend mx
components but not you’re own, or this only possible with ActionScript
components and not mxml….?

 

Thanks,

 

Tony

RE: >< [flexcoders] Starting a Project Now! FLEX 1.5 or 2.0?

[Tony Pujals]

Regarding the comment on Flash penetration
below, I don’t know how representative this is of the entire browser
market, but my experience with getting users to upgrade has been positive to
date. The other day I was giving a demo and speaking to a person over the phone
who was prompted to update his flash player version; he immediately did so
without problem, restarted his browser and within a moment was ready to proceed
with the demo.

 

Personally, I’ve never seen a user
balk when the browser prompted him/her to upgrade Flash. It certainly isn’t
the same proposition that updating the Java plugin is. I can’t speak
officially, but I don’t see upgrading to Flash 8.5 being a reason to be
reluctant to exploit the new player and all that Flex 2.0 brings to the table.
I have an impression that quite a few users never upgrade Flash for the same
reason they don’t upgrade Acrobat reader. They simple haven’t been
prompted to do so for any of the content they have accessed, or didn’t
feel the content was compelling enough to tempt them.

 

I’m sure some people might be put
off by it, and I realize there are admins out there who actively prohibit ActiveX
(and upgrades), but if it really is a huge showstopper, I’d really like
to hear some evidence of that. It would be good to factor that into our
internal decision making processes, but for now I would say that from an
engineering and product management perspective, we’re not the only ones
eagerly awaiting the 8.5 release.

 

My 2 cents only….

Hello people,

Thanks for all the input on this topic. I am fine
with the Flash
Player 8.5 issue as I will be controlling access
to this first project
and can supply the users with the correct player.

The second project will not launch until the end
of the year at best.

Now as far as the "High" cost of
"FLEX". We are already a member of
the enterprise solutions and the development
program with Adobe and We
have already made the choice to partner with Adobe
on various other
software, So I do not think we should have a
problem with FES.

Although I would like to see a bundle created with
FES, Media Server2,
ColdFusion, and Breeze. LOL

RE: [flexcoders] Re: Muliple flex apps on tomcat

I second Dave’s recommendation
regarding pre-compilation. Our team ran into the same issues with OutOfMemoryErrors
thrown on our linux servers (never on any of the Windows machines). The
solution was to deploy pre-compiled SWFs.

You can run many web apps
that serve SWF content.  However, I would
seriously avoid the JIT compilation in favor of
pre-compiling your SWF
files.  That SWF compiler leaks pretty
heavily in 1.5.  

In nay case, you should be able to do what you are
trying here.  I am
curious why you want to run these as seperate web
apps?  Whats the value?

I would really encourage you to look into
pre-compiling the SWFs.

Hi Everybody,

If its a hack, workaround or the way its suppose
to work does not 
matter as I have found a solution that works.

Just as the documentation for the PopUpManager
suggests, the solution 
is to put a independent layer underneath the layer
containing the 
components and then disable this layer. This
disabling will 
eventually intercept all user input and discard
them as it is 
disabled.

Thanks anyways for the help everybody.

Cheers,
Pedro

RE: [flexcoders] Re: Capture events a la the underlying transparent window from PopUpManager

[Tony Pujals]

I basically posted the same question on
2/14/06 (“Mouse Event Filtering”) and nobody was able to provide a
solution.

 

I found this link that explained the
grisly situation with Flash event capturing (http://senocular.com/flash/tutorials/buttoncapturing/).
I had to move on for a while working on a rich text editor that worked around
Flash’s also grisly text selection timing problems (which you have to
deal with if you want to implement something like a text styles toolbar, and
you want to refresh the selected text, but need to do it after Flash finishes
its updating several frames later).

 

Anyway, I’m working on a slight
variation of the delegation method discussed in the article, but I’m not happy
that I have to do something that the framework should be doing for me, which is
checking to see if a mouse event occurs within the bounds of the topmost
component of a container’s children, and invoking the mouse handler
there.

 

If I come up with a reliable and generic
enough solution, I’ll be happy to post it … but it would be nice if
someone with experience/knowledge in this area could at least indicate if this
is a problem that has been addressed with Flex 2.0….

 

-Tony

Sorry, I really don't remember how this worked in
Flex 1.5, but can
you try setting event.bubbles to false (in the
mouseDown handler)?

RE: [flexcoders] Actionscripting and dispatching Events

[Tony Pujals]

Without looking at your code or knowing specifically where the references 
stored in currentGroup originated ... I would nevertheless suspect that you are 
working with Flex 1.5 and having an issue with the "this is not this this"  
scoping problem. You might want to read these:

http://www.macromedia.com/devnet/flash/articles/eventproxy.html
http://www.erikbianchi.com/archives/flash_platform/


Essentially, when you are adding your event listeners, add a delegate to ensure 
that on callback the listener will be using the correct scope when 
dereferencing the event parameters.

Where you might have code like this:

  controller.addEventListener("changeGroup", function(event) {
// warning: grp may be in wrong scope...
var grp = event.group;
// do something...
  });

Change it to this:

  controller.addEventListener("changeGroup",
  mx.utils.Delegate.create(this, function(event) {

var grp = event.group;
// do something...
  }));
  


Or if your code looked like this:



  controller.addEventListener("changeGroup", callbackFunc);

  
Change it to this:

  var callbackDelegate;
  ...

  callbackDelegate = mx.utils.Delegate.create(this, callbackFunc);

  controller.addEventListener("changeGroup", callbackDelegate);
  ...

  Controller.removeEventListener("changeGroup", callbackDelegate);



Good luck.

-Tony

Subject: [flexcoders] Actionscripting and dispatching Events

Hey coders, I am running into a problem with dispatching events in AS.

I have an EventDispatcher as part of a Controller object I created.  This 
EventDispatcher has 3 filter objects registered as listeners for a certain 
event.  Now, when I fire that event, I fire it like so:

eventDispatcher.dispatchEvent({type:"changeGroup", group:currentGroup});

Now currentGroup is another object of type Group, and has an associative array 
of arrays in it of different pieces of data used by the different filters.  

Now,through tracing, when before I dispatch this event, the object is 
intact(all its fields are there with no undefines), but when I dispatch the 
event, and trace its properties on the filter side, I'm getting undefined.  
I've tried this via casting to Group object, as well as just leaving it in its 
Object state.   In particular, an array inside the array is coming up as 
undefined.
The weird part of it is, on the filter side, when I trace the array's length, 
its there, but when I attempt to do anything else to it after that initial 
trace call, its all undefined. 

Am I doing anything blatantly wrong?

Many Thanks

Nick

RE: [flexcoders] Re: Mouse Event Filtering

Hi Matt, 

Yeah, I mention below that I tried this and got a partial solution to my 
problem. The issue is that once I do that, ALL the events are blocked and I 
don't know the correct way to ensure that the toolbar buttons themselves get 
passed mouse clicks But if the solution lies in pursuing this direction, 
then thanks for the tip.

Yes, that's exactly the similarity -- but an obscured component should not even 
have to be aware of a toolbar component above it. It should not receive a 
mouseDown event if the component above is handling it. It's only my toolbar 
canvas that seems to allow events to "pass through" to the TextArea below it -- 
the toolbar buttons don't.

As far as code, I'll create a streamlined example that should make it a little 
easier to see what I'm talking about  Thanks again, Doug.

[Tony Pujals]

Hey Doug - thanks for the input. This is a link to a screenshot that may help 
clear up the issue:
http://www.geocities.com/tonypujals/eventcapture.jpg

What the screenshot shows is that I dragged the toolbar over the TextArea 
component. Then, I dragged the toolbar just a little bit again ... which 
resulted in the highlighted text that you see displayed. In other words, the 
toolbar isn't handling events from other components when it shouldn't - the 
opposite is happening: other components are receiving events I don't want them 
to. When I mouse down and drag the toolbar, I want it to move without events 
propagating to components below it. I want the toolbar events to be consumed 
when they act upon the toolbar.

Also, what the picture doesn't show since Windows doesn't capture it in 
screenshots is that the mouse cursor over the toolbar is an i-beam cursor - 
which is what it should be when over text, but not over the toolbar. It is only 
an i-beam when it is not specifically over one of the toolbar buttons, just the 
toolbar gradient background Canvas.

Rather than using mouse handlers for the toolbar, I tried overriding the 
onMouseXXX methods of MovieClip in the hope perhaps that this would prevent 
some superclass behavior which forwards the mouse events to further processing, 
but it didn't help

Argh...

I should have pointed out I was talking specifically about the

Tony, I had a similar problem in Flex 1.5 with a custom TitleWindow 
component that was receiving events from objects underneath it.  
Never did find out exactly why that was happening; non-100% alpha 
value, perhaps?  Anyway, I solved it by wrapping a simple check 
around the event handler that makes sure the target property of the 
event is the current object: 

if (event.target == this) { // handle the event... }

It might be worth trying that somewhere, like in a delegate for the 
mouseMove event or in handleEvent().

Hope that's of some help.

RE: [flexcoders] Mouse Event Filtering

[Tony Pujals]

Well, the Flash asdocs really don't make this clear, but I initially had a 
suspicion that overriding a handler instead of registering a listener might be 
the answer. I didn't pursue that direction right away because the method 
signatures don't return a Boolean or some other value to indicate that an event 
was handled and no further processing is wanted.

In any case, I was able to achieve the glass pane effect that I wanted this 
morning with the following code:


options = { width: "100%", height: "100%"};
Canvas(createChild(Canvas, "_glassPane", options));
_glassPane.setStyle("backgroundColor", "#FF00FF");
_glassPane.alpha = 0;
_glassPane.visible = false;

MovieClip(_glassPane).onPress = function() {}


All of the above was required: without a backgroundColor being set, events 
weren't captured at all; The alpha, of course, was to make the glass pane 
actually invisible (there maybe other properties beside backgroundColor that 
also work for causing events to get caught, but I haven't experimented). The 
visible property -- once a backgroundColor property is set -- is what enables 
and disables the event capturing.


However, for the toolbar that I also wanted to capture events so the text 
component below doesn't receive them, this is not yet a complete solution 
because it also prevents the child components (the toolbar buttons) from 
getting any events either. I've written some code to iterate the child 
components, but I don't know what to pass to them -- it seems intrinsically 
wrong that the toolbar needs to become an event manager from its onPress 
handler:

// doesn't work -- onPress doesn't have event parameter anyway...

MovieClip(this).onPress = mx.utils.Delegate.create(this, function(event) {
  var comp : UIObject = null;
  for (var i : Number = 0; i < childDescriptors.length; i++) {
comp = getChildAt(i);
if (hitTest(comp)) {
  comp.handleEvent(event);
}
  }
});

(Incidentally, if there is some other more appropriate way for iterating child 
components, I'd appreciate hearing about it).

So Flash/Flex gurus ... what am I missing here...? Thanks!

RE: [flexcoders] event bubbling Flex 1.5

[Tony Pujals]

I just wanted to follow up in case my last
post wasn’t totally clear. JesterXL said:

 

> > I usually do:

> > dispatchEvent({type:
"someEvent", target: this});



What I wanted to make sure I pointed out is
that Flex will set the target property to ‘this’ (the object calling
dispatchEvent) when the event gets broadcast, overwriting any value you may set.
So although this actually shows up in some of the doc examples, don’t do
it, it doesn’t work – it may have “seemed” to work, but
only coincidentally because ‘this’ is generally what you want.

 

You know, I also find the behavior not
exactly intuitive because of semantic reasons. If you think of ‘target’
as meaning the component upon which an event occurred, then this value should
be preserved up the chain; in any case, I think target is a poor naming choice.
An event broadcaster is a ‘source,’ like in Java, or something
along those lines. For a listener receiving a notification, source ought to
point to the broadcasting object, even if it is just a middle link in what is a
chain of listeners. Target should be a value that refers to a component and is
set only once and preserved up the chain Or something along these lines….

 

;-)

bubbling Flex 1.5



 

So funny – this thread just caught my
eye because I just had to deal with the very same issue.

 

When you call dispatchEvent, the target
property is always overridden. Although I have seen a few erroneous examples,
the docs tell you not to set the target property in the event object because it
will be explicitly set to refer to the object that is dispatching the event.
Therefore, the original “target” will be lost.

 

I bubble up my events through chaining (for
example, a ThemeManager that propagates theme changes that propagates scheme
changes that propagates individual style (font and color) changes), but I
preserve the original event with a rootEvent property. The chain of handlers
continue to add this property to the new event that is getting dispatched up
the chain, preserving the value that each listener receives.

 

I should point out that athough preserving
the original event is useful, each listener in the chain generally needs to add
other context aside from just “bubbling” up the original event. The
ultimate listener can’t do much with the rootEvent object (eg, a font
style), without the additional context added by the listeners in the change
(for example, current theme : page title scheme : new font style).

RE: [flexcoders] event bubbling Flex 1.5

[Tony Pujals]

So funny – this thread just caught my
eye because I just had to deal with the very same issue.

 

When you call dispatchEvent, the target
property is always overridden. Although I have seen a few erroneous examples,
the docs tell you not to set the target property in the event object because it
will be explicitly set to refer to the object that is dispatching the event.
Therefore, the original “target” will be lost.

 

I bubble up my events through chaining (for
example, a ThemeManager that propagates theme changes that propagates scheme
changes that propagates individual style (font and color) changes), but I
preserve the original event with a rootEvent property. The chain of handlers continue
to add this property to the new event that is getting dispatched up the chain,
preserving the value that each listener receives.

 

I should point out that athough preserving
the original event is useful, each listener in the chain generally needs to add
other context aside from just “bubbling” up the original event. The
ultimate listener can’t do much with the rootEvent object (eg, a font
style), without the additional context added by the listeners in the change (for
example, current theme : page title scheme : new font style).
