[flexcoders] Re: Stupid question regarding sizing of mxml components

[aduston1976]

Hi Alex, Thank you for your reply. 

> then minHeight=0 should allow
> for scrollbars on the top.

That's what I would think too, but it is incorrect. I am using build
477 of Flex 3 SDK version 3.0.0. Here is my entire mxml application:


http://www.adobe.com/2006/mxml"; layout="absolute"
initialize="init()">




















The _outer VBox gets the scrollbars.

I am running on Flash Debug player 9,0,124,0 on Mozilla/5.0 (X11; U;
Linux i686; en-US; rv:1.9) Gecko/2008061015 Firefox/3.0.

Is this a bug? Any other suggestions to accomplish this?

Thank you again,
Adam

RE: [flexcoders] Re: Stupid question regarding sizing of mxml components

[Alex Harui]

If the bottom vbox's content is taller than the parent's 300 pixels, I
don't think the top vbox will get scrollbars.  But if there's room for
both the top to show some and the bottom, then minHeight=0 should allow
for scrollbars on the top.

Hi dbronk, I need the top vbox to scroll but not the bottom one.
Assuming that your sdk is sufficiently similar to mine, the solution
you gave makes them both scroll. You can achieve this effect very
easily without the Canvas components in your solution: just set
height="50%" and minHeight="0" for both inner VBoxes. Unless I'm
missing something in your reply, the original problem remains

Re: [flexcoders] Re: Stupid question regarding sizing of mxml components

[greg h]

Hi Adam,

Does the following meet your criteria?

SWF here:
http://flexflashvideo.com/flexcoders/08/07/VBox_scrolls/

Source here:
http://flexflashvideo.com/flexcoders/08/07/VBox_scrolls/srcview/source/

Note that content is being clipped on _bottom since it has
verticalScrollPolicy="off"

So, content matters.

Nested containers must fit inside their parents.  So in cases where all of
the contents of the nested container can not be displayed, scroll bars are
generally desired.

btw ... I removed the minHeight="0".

hth,

Thanks, that was the problem. I'm still wondering why, if the error 
machine knew that the target was the wrong type, it couldn't tell me

RE: [flexcoders] dynamic move

[Rick Winscot]

So.. It looks like you have some issues with the line
moveSketch.target="sketchBox";  since the target is an Object and you
are setting it to a String. which is an Object but not the right _type_ of
Object. The compiler isn't going to have a spaz but it will surely cause a
runtime error. Use moveSketch.target=sketchBox; instead.

In this code I'm dynamically creating an HBox, adding an image to it, 
adding the box to a Panel, and then creating a Move() to move the Hbox.
It produces the error below, which says "value" is not a function. WHAT 
VALUE? Why doesn't it name the value ? What did I do wrong ?
The error comes when I add the final line, moveSketch.play();

var sketchBox:HBox = new HBox();

[flexcoders] Form Processing with Flash/Flex

[brucewhealton]

Hello all,
 I've recently gotten a good handle on using the spry
framework in Dreamweaver and the tags that are part of a good practice
when creating forms in DW.  Now, I'm looking at creating and
processing forms with Flash and Flex.  This is different.
 Can someone suggest some reading or content on the web, or
your own explanations that might help with doing this.  I can work
with PHP for form processing.  I want to be sure to setup my Flash and
Flex forms for processing correctly.  I do have some rather extensive
forms too.  I'm not just talking about a feedback form with 2 or 3
input text fields.
  It would be helpful to be able to check the forms for valid
entries... something that Javascript would do in a xhtml form.  
  Can someone recommend a good form processor that uses PHP? 
and would work fine with Flex/Flash, if that is an issue.
Thanks,
Bruce

Hi dbronk, I need the top vbox to scroll but not the bottom one.
Assuming that your sdk is sufficiently similar to mine, the solution
you gave makes them both scroll. You can achieve this effect very
easily without the Canvas components in your solution: just set
height="50%" and minHeight="0" for both inner VBoxes. Unless I'm
missing something in your reply, the original problem remains
unsolved. Adam

Not sure why, seems like a bug.  But if you wrap the inner vbox's in a

[flexcoders] Context menu triggers browser crash

[Guy Morton]

Hi there

I have a Flex 2 app that has a custom context menu attached to the
root application object. It works without incident on the Mac, but on
windows, choosing an item from the context menu sometimes causes the
browser to crash. 

There appears to be no pattern to it, though it does seem to occur
more frequently when choosing a menu item that calls a function that
does a couple of sequential HTTP requests and thus can take a little
while (maybe a second or two) to complete.

This happens in both IE and Firefox on windows, so for once we can't
just blame IE. :-)

Anyone seen this behaviour before and know what causes it, or how to
work around it?

TIA 

Guy

[aduston1976]

Paul, Thanks for your reply.

> Have you tried setting the verticalScrollPolicy?

No, because looking at BoxLayout#measure, it seemed to have no impact
on the measure of the component. But, just to be sure, I just
empirically confirmed this.

I put in ids at first, but they seemed to obfuscate more than they
helped, since there were only two inner VBoxes. But here is the
problem restated with ids:

How to make _top scroll only without _bottom scrolling?

> This might be helpful: 

Thanks for the link, but I'm afraid it didn't help me with this
particular problem. It is interesting, a search brought up several
similar posts in the past with the same question, but there's never
been an answer, just suggestions a la "have you tried minHeight=0?".
Just to be explicit, I have set minHeight and verticalScrollPolicy on
the relevant mxml elements in my example. I wonder if mxml provides
any way to solve this or if I have to use the updateDisplayList
override I described initially.

[flexcoders] dynamic move

[[EMAIL PROTECTED]]

In this code I'm dynamically creating an HBox, adding an image to it, 
adding the box to a Panel,  and then creating a Move() to move the Hbox.
It produces the error below, which says "value" is not a function. WHAT 
VALUE? Why doesn't it name the value ?  What did I do wrong ?
The error comes when I add the final line, moveSketch.play();



var sketchBox:HBox = new HBox();
   var sketchImg:Image=new Image;
   sketchImg.source="Journeysketchsm.gif";
   sketchBox.addChild(sketchImg);
   thePanel.addChildAt(sketchBox,0);

var moveSketch:Move = new Move();
moveSketch.target="sketchBox";
moveSketch.xTo=150;
moveSketch.duration=3000;
moveSketch.play();
 

TypeError: Error #1006: value is not a function.

Re: [flexcoders] Stupid question regarding sizing of mxml components

[Paul Andrews]

Have you tried setting the verticalScrollPolicy?

If you want to refer to specific containers, give them an id so we can be 
sure which is being refered to.

That is a ton of information Greg, thanks so much! I have viewed the Lynda

Re: [flexcoders] Component Questions

Hi Dan,

For more of a walk through on "Dispatching Events from Custom Components"
see this online training title from Lynda.com:

Flex 3 Essential Training with: David Gassner
http://movielibrary.lynda.com/html/modPage.asp?ID=438

If you do not already have an account for the lynda.com Online Training
Library, you can sign up for a 7-day Free Trial here (requires only an email

For your immediate requirement see:
10. Programming with Events
Dispatching Events from Custom Components
Creating and using custom event classes
Dispatching and handling custom events

Regarding Alex's comment, I concur.

The following Lynda.com Online Training title can introduce you to the
basics on "Centralizing data storage with the ModelLocator pattern".

Flex 2 Beyond the Basics with: David Gassner
http://movielibrary.lynda.com/html/modPage.asp?ID=290

9. Client-Side Data Handling
Centralizing data storage with the ModelLocator pattern

Note:  This lynda.com training video on the ModelLocator pattern references
(but does not use) the Cairngorm "microarchitecture".  The training video
covers just using a "microarchitecture free" implementation of a singleton
ModelLocator class.  This will give you the simplest, most straightforward
understanding of what Alex is referring too.  (Highly recommended.)

Several microarchitectures are sometimes used in Flex developement that
implement more design patterns than just ModelLocator.  Two that I am most
familiar with are Cairngorm and PureMVC.org.  Just be forewarned that in
structuring your codebase around these microarchitectures you will be
committing to some significant overhead in terms of learning and the
ultimate organization of your codebase. (Meaning, save them for some project
after your first ever MVC in Flex project :-)

Using microarchitetures like Cairngorm do ensure the use of a singleton
ModelLocator classes.  For primers on Cairngorm see:
http://cairngormdocs.org/
http://labs.adobe.com/wiki/index.php/Cairngorm

And this must read:

I agree with you but is there an easy way to do this without diving into a
framework right away? I understand frameworks in general but I am still
learning the ins and outs of Flex. I am just trying to go up the 45 degree
ramp instead of the 90 :)

[flexcoders] Stupid question regarding sizing of mxml components

[aduston1976]

Hi, here is an easy one:



... lots of stuff ... 


... lots of stuff ... 



When lots of stuff is added, I want the top inner VBox to show
scrollbars, not the second. Any way to do this? Other than by setting
minHeight="0", which I've tried and which doesn't work?

Here is a non-standard solution: I could change the outer VBox to a
VBox inheritor and override updateDisplayList, and then set
_first.height manually after calling super.updateDisplayList. Is this
totally wrong for any reason? Will I end up breaking Flex?

Thanks,
Adam

I seem to be in the minority opinion on this topic, and you must also
know that I develop framework components and not full-fledged production
applications, but if you are headed to MVC, there should be a central
model class that contains the data, and the UI should only reference the
model's data and not really "own" it, or the services that fetch the

and not really dispatch events for other UI to manage.

Re: [flexcoders] Component Questions

[greg h]

Hi Dan,

I think you might need to include the [Event] metadata tag in your
components that are executing dispatchEvent().

Something like this:


[Event(name="clientSelected")]


For details see this page in the docs:
http://livedocs.adobe.com/flex/3/html/createevents_3.html#160168
And at this link, go to #2 at the top of the page and select the link for
"Using the Event metadata tag"

The text under that section starts off ...
You use the [Event] metadata tag to define events dispatched by a component
so that the Flex compiler can recognize them as MXML tag attributes in an
MXML file. ...

Re: [flexcoders] Module hell... Flex 3

[Sebastian Mohr]

Hi Alex,

when I call the CairngormEvent
the first time just like this:

   new LoadTestEvent().dispatch();

the moduleReadyHandler - method
will not be called. But when I call the
LoadTestEvent a second time, once
again, just like this:

   new LoadTestEvent().dispatch()

the moduleReadyHandler - method
will be successfully called.

I believe that the two EventListeners:

   ModuleEvent.READY and
   ModuleEvent.ERROR

are not registered correctly in the first place.
But I don't understand why!? Maybe there is
an issue related to the FrontController?

Thank you,
masu

[flexcoders] Re: Parallel requests using RemoteObject with RTMP

[mmormando]

It doesn't have anything to do with Flex, its IE. IE 6 and I believe
7, and Firefox 2 all default to only allow 2 downloads from a single
subdomain. I got that from the folks at Yahoo that bring us the YSlow
stuff. If you are using an Apache front end you could make your
request to multiple subdomains, e.g. data1.yourdomain.com and
data2.yourdomain.com would let you go to 4, conversely if you have
control of all the computers hitting your service there are registry
tweaks you can set, something along the lines of
max_server_connections, that's from memory so don't take it as
doctrine. I've also read that IE 8 beta defaults to something like 30.
I'm using Firefox 3 and set it to 30, as well as allowed it to use
http pipelining, up to 30 requests per socket, and things seem to just
scream!!
Good luck

Re: [flexcoders] Component Questions

[Douglas Knudsen]

You need to inject data from parents into children.  If children need
to send data up the chain to parents, use a event.  Thus, in the below
add a public variable client and set this upon creation like this

[flexcoders] Component Questions

[Dan Vega]

I built a small app that has 4 screens and everything is working great. I
want to learn more about breaking up the views into different components
before I move on to mvc in Flex. My question is lets say I have my main
application and then each of my screens are views. In my main application I
have a public variable called _client. On the first view I am trying to
access that object and the compiler is telling me it is undefined. In my
code you will the line _client = selected.

My question is how does the component know about the data declared in the
main application ?

RE: {Disarmed} RE: [flexcoders] Calling AS3 functions

[Alex Harui]

If another mxml file is a state, then its stuff may not exist until you
are in that state.  I'm not sure how you set that up though.  That's the
kind of code that might help us see what is going wrong.

 

Normally, if I have two MXML files:

 

-loginForm.mxml





Public function foo() {}





 

-login.mxml-







Private function callFoo() { bar.foo() }





 

I'm guessing that the object doesn't exist yet since the compiler seemed
to like what you are doing.

Yes, I did change that already it does say returnEmail on both sides

Very interesting...  

 

This would be a better question then...  

 

I've got a login.mxml file which controls the different states the login
can be in.  Each state essentially is another mxml file.  I'm calling a
CFC function to process the login which is in the loginForm.mxml.  This
function has the email address and name as returned by the CFC.  How can
I pull that information out and into the login.mxml file?  So if what
you are saying is that each of the files are their own class, I would
need a way to call that class from another class.

 

I did change that method to be public but still wasn't able to "see" it.
What is the syntax to access an external class from another class?  Do I
need to reference class.function()?

Each mxml has its own (document) scope.  It essentially defines a class.
A method must be public in order to be accessed from outside the class,
you cannot access protected from outside the class.

 

Your snippet doesn't have id's or show the relationship between the two
classes so it is hard to say why it isn't working. Also, you appear to
be trying to call returnEmail when the snippet only showed a returnName
method.

The class exists in the loginForm.mxml but the mxml code exists in the

RE: [flexcoders] Flex Text Selection Problem...

[Alex Harui]

In actionscript, you can't use {} to bind.  You have to use
ChangeWatcher and/or other.mx.binding classes.

 

However, I usually just assign when the result from the server comes in
and skip binding altogether.

[flexcoders] Re: 3 tier architecture using adobe flex

Well, Flex and FP are presentation layers. You would need to have
something running on the server. I am using a traditional ASP that
calls OLE servers that in turn talk to the SQL back-end.

Hi there,

I have the same problem as dbronk mentioned 
(see below) in conjunction with Cairngorm 2.2.1.

I always have to dispatch the LoadTestEvent 
twice to make the LoadTestCommand calling 
the moduleReadyHandler-method. here is the 
code:

package com.test
{
   import com.adobe.cairngorm.commands.ICommand;
   import com.adobe.cairngorm.control.CairngormEvent;

   import flash.system.ApplicationDomain;

   import mx.events.ModuleEvent;
   import mx.modules.IModuleInfo;
   import mx.modules.ModuleManager;

   public class LoadTestCommand implements ICommand
   {
  private var moduleInfo:IModuleInfo;

  public function LoadTestCommand()
  {
 moduleInfo = ModuleManager.getModule('TestModule.swf');
 moduleInfo.addEventListener(ModuleEvent.READY,
moduleReadyHandler);
 moduleInfo.addEventListener(ModuleEvent.ERROR,
moduleErrorHandler);
  }

  public function execute(event:CairngormEvent):void
  {
 moduleInfo.load(ApplicationDomain.currentDomain);

  public function moduleReadyHandler(e:ModuleEvent) : void
  {
 trace('SUCCESS');
  }

  public function moduleErrorHandler(e:ModuleEvent) : void
  {
 trace('ERROR');
  }

}

Is there a solution to dispatch the event only once 
to make the Command loading the module?

I'm trying to get something very basic to work with modules. I have
my app and two swf modules (Form1.swf and Form2.swf). Each test
module simply has a couple TextInput fields. I have also extended
Module so I can follow what is going on and I will be adding custom
code later. MyModule extends Module has:

public function MyModule() {
super();
trace("Module constructor");
addEventListener(FlexEvent.INITIALIZE, onInitialize);
}

protected function onInitialize(event:Event) : void {
trace("Module.onInit: " + this.toString());
dispatchEvent(new BaseEvent("moduleLoaded", this, true, true));
} 

Very basic. I want to be notified when the Module is initialized.

When I have the following code inline to a button click which will
load the module it works fine

var moduleLoader : ModuleLoader = new ModuleLoader();
moduleLoader.id = moduleName;
moduleLoader.url = moduleName;
moduleLoader.loadModule();
moduleLoader.addEventListener("moduleLoaded", onModuleLoaded);
moduleStackChild = moduleLoader;
moduleStack.addChild(moduleStackChild);
moduleMap.put(moduleName, moduleStackChild);

My onModuleLoaded function gets called.

Now for the issue. If I take this code and place it into a common
object it no longer works THE FIRST TIME. I have two buttons, one to
load Form1.swf and the other to load Form2.swf. When this code to
load the module is in a separate class, it doesn't matter if I click
button 1 or 2 first. It simply will not work on the first click. 
Second click and beyond work fine. Also, in debug mode, works great
every time. What happens is that the last thing that runs is the
loadModule() command. The constructor on MyModule never executes on
the first execution. Future executions work fine.

I'm hoping I explained this good enough as it is very strange. But I
definitely want to have this function in my util classes and not have
to duplicate the code all over the place.

Suggestions?

Thanks,

Re: [flexcoders] SQLlite limitations

Whatever you should retrieve data in parts if too much rows.

var stmt:SQLStatement = new SQLStatement();
stmt.sqlConnection = conn;
stmt.text = "SELECT ...";
stmt.addEventListener(SQLEvent.RESULT, selectResult);
stmt.execute(20); // only the first 20 rows (or fewer) are returned

function selectResult(event:SQLEvent):void
{ var result:SQLResult = stmt.getResult();
if (result.data != null) { // ... loop through the rows or perform other 
processing ...
 if (!result.complete) {
stmt.next(20); // retrieve the next 20 rows
} else { stmt.removeEventListener(SQLEvent.RESULT, selectResult);
} } }

4 rows.  Should that be happening?  Is there a max execution time for

[flexcoders] Re: looking for best Data Service

[markgoldin_2000]

If you are looking for a true push solution take a look at
Lightstreamer push server. They have examples for Flex. I have created
 a push solution based on the Lightstreamer push server, .Net data
adapter, Flex JS bridge, and a few more things. Took me some time but
it works very good. I haven't tested it in environment as heavy on
users as yours, but it looks very promising for upscaling. I would
suggest to take a look at the LS push server, and their samples. BTW,
documentation is very good. Then if you would want I can show what I
have so far.

[flexcoders] Re: GroupingCollection compile error

[Sid Maskit]

Somebody else may see something wrong with the code you posted, but
I'm not. It's unclear from your message where the error is occurring.
Based on the error message, it may well be that the error is in the
code above what you posted. 

I would start by pulling out the code you posted, and replacing it
with a very simple visible element, such as a label or text input, and
see if that makes the error go away. If it doesn't go away, you know
the error is somewhere else in your code.

I'm working on a logon class in Flex 3.  I've got a login.mxml which
controls the overall views (logon/register/logout) all in the same box
depending on what state the user is in.

 

In the loginForm.mxml (included in the logon.mxml), I've got a function
called protected returnName():String

 

 

Function I want to call from the loginForm AS3 script:

protected function returnName():String   (I've also tried public in case
it was not available in that area of code)

{

   return this.username.text;

}

 

Snippet from my mxml code:

Xmlns:login="com.ft.views.login.*";

 

...

 



 

   



   



   

  <-
line in question 



   









 

I can't seem to figure out how to reference the method as I get the
error: 1180: Call to a possibly undefined method returnName.

 

I've tried:





Among many others...

 

This is probably pretty simple.  I really appreciate your help.

[flexcoders] PopUpMenu Button item click....

[sudha_bsb]

Hi,

I am having strange problem with PopupMenuButton. I am having a
popupmenubutton with submenus as its items.

When I click on the parent menu item( not on the sub menu item), how
can i get the index of the parent menu item  on which it is clicked.
Which event gets triggered for this. The itemClick event is triggered
only when we click on the sub menu item which is in the last hierarchy.

Similarly when i click on the submenu item, i need the index of its
parent menu with respect to popumenu button.

Here is the code...

When I click on Inbox or Calendar menu..i need its index(0 or
1)..Similarly when I click on Personal menu item...I need Inbox
index(its parent menu index.)

Please help

[flexcoders] Re: Binding for Dynamic Datagrid

[limhy0306]

Hi,

I've tried using the suggestion:

myDG.dataProvider={ myData }

But compilation has syntax errors: rightbrace is unexpected.



Also, I've read about the binding regarding changes to the property 
for the ArrayCollection; that we need to use itemUpdated to inform 
about changes to the list.

Basically the myData is a list of a class: MyClass.

public class MyClass
{
   private var _evt:ArrayCollection;

  ... 
}

The var _evt changes in real-time & this changes need to be 
refreshed in the Datagrid.

However, not all instances of MyClass stored in myData changes. 
In this case, I only want to redraw parts of the Datagrid that 
changes only.

Thank you.

Regards.
