[flexcoders] Syntax of using a variable to make an object

[john fisher]

I am stuck on some basic AS syntax.

Here is some Adobe sample code:

[Bindable]
public var dpac:ArrayCollection =  new ArrayCollection([
   {A:2000},{A:3000}, {A:6000} ]);

public function addDataItem():void {
var o:Object = {"A":2000};
dpac.addItem(o);
}


Inside a loop, I need to add a data item to an arraycollection, but I
need to get the name of the data  and the result of the data from an XML
file.
OK I've got those two things working, but now my name and dataresult are
variables not ints and strings.

[Bindable]
public var dpac:ArrayCollection =  new ArrayCollection;
for each ( var something:XML in myXML.children()) {
var dataresult:Obj = something ;  // don't know type of result 
ahead of time...
var name:String = something.name ;

var o:Object = { name + ':' + dataresult } // WRONG! 
dpac.addItem(o);

}

I am going wrong where I try to create an object out of method-results or 
variables that can be additem'ed to an arraycollection. 
And I don't really get the curly brace syntax, as you can see...

Thanks for guidance here...
John

PS what is the proper name for this like 'passing by reference vs passing by 
value' or?

RE: [flexcoders] what is a String? (default encoding question)

[Gordon Smith]

I think AS3 uses UTF-16 internally, but I'm not sure about that, and it might 
change in the future. I suggest that you do some timing tests to see what's 
fastest.

Subject: [flexcoders] what is a String? (default encoding question)

How is a string represented internally in Flex?  It never actually says it in 
the help for String.  Is it UTF-8?  I think this because because mxml uses 
utf-8 as the encoding in the ?xml directive, ByteArray seems to treat utf-8 
specially, and ByteArray.readMultiByte says the return value is a utf-8 encoded 
string.

The reason I ask is because I'm reading some string data in from a binary file 
and I'm trying to figure out the most CPU efficient way to put it in the file.  
I want it to be in the file in the same encoding that won't require Flex to 
translate from one encoding to another when storing it in a String variable.

Thanks.

[flexcoders] Lookup performance: Dictionary in memory vs. SQLLite

[arieljake]

I am developing an AIR app, and am wondering what people believe would
be faster...I plan to implement an RSS reader in the app, and want to
filter the entries that have been read/saved already, so I will need
to do a lookup on every downloaded RSS item in a dictionary to see if
the user has looked at that item already.

Would it be faster to read these in from the SQLLite DB at startup and
check these in memory, or just perform queries on the SQLLite db directly?

Thanks.

[flexcoders] Re: Flex uploader / accessing local files?

[Rob Kunkle]

As far as I know its not possible to get a File object directly off of
the client machine...if the client is using flash 9. 

It looks like this was resolved in Flash 10 though. Yay!

[flexcoders] Re: Extending UIComponent memory issues.

[flexaustin]

Well my container is about 4 classes deep. What I am focused on now is
the CarouselImage class as each carousel comp contains up to 8 of
these and their can be 2000 carousel components...see my delim? I know
at best it will be next to impossible to use but it has to be done. 

I tried converting my CarouselImage to a flexsprite but Flex rejects
it saying it needs to implement IUIComponent.

Hi Mark,

You can come probably up with a more elegant way to handle each
possibility, but here's an idea.

myDG.verticalScrollPosition = (myDataProvider - array[i]) >
(myDataProvider.length - myDG.rowCount) ? (myDataProvider.length -
myDG.rowCount) : array[i];

RE: [flexcoders] datagrid scrolling problem

[Tracy Spratt]

You will have to add conditional logic to use the rowCount and index to
calculate the scroll position.

Subject: [flexcoders] datagrid scrolling problem

 

I have a basic datagrid that is getting the data from an 
arrayCollection with each item having a startDate field, among 
others. My boss wanted me to have the datagrid scroll down to the 
item that has the same start date as todays date. Basically I'm just 
looping thru the arrayCollection to find it and scroll down to it 
using:

myDG.verticalScrollPosition = array[i];

This works fine unless that item is at the end of the datagrid. Then 
it adds rows to the DG so that item is at top. What would be the 
proper way to do this so if it's the last item, it just scrolls to the 
bottom without adding more rows?

Thanks,
Mark

 

RE: [flexcoders] Re: sailorsea21 - RemoveChild question.

[Tracy Spratt]

Because you introduced the Vbox container.  Neither the button or the
moduleloader are children of modulestile, they are children of the Vbox.

 

You now need to keep references to the Vbox instead, and remove that.

[flexcoders] datagrid scrolling problem

[Mark]

I have a basic datagrid that is getting the data from an 
arrayCollection with each item having a startDate field, among 
others.  My boss wanted me to have the datagrid scroll down to the 
item that has the same start date as todays date.  Basically I'm just 
looping thru the arrayCollection to find it and scroll down to it 
using:

myDG.verticalScrollPosition = array[i];

This works fine unless that item is at the end of the datagrid.  Then 
it adds rows to the DG so that item is at top.  What would be the 
proper way to do this so if it's the last item, it just scrolls to the 
bottom without adding more rows?

Thanks,
Mark

[flexcoders] Re: Overriding width of DateField

[aceoohay]

Gordon:

I did the following;

override protected function measure():void 
{
super.measure();

measuredWidth=94;
measuredMinWidth=94;
}

It still doesn't seem to change the width of the component in 
flexbuilder's design mode.

Any ideas?

[flexcoders] Re: how to add internal padding in canvas?

[markflex2007]

But why I can do this with actionscript

I have the object like

public var canvas:Canvas = new Canvas(); 

but I get error for

canvas.top = 10;
canvas.left = 10;

I wonder how to do this with actionscript.

[flexcoders] what is a String? (default encoding question)

[Pan Troglodytes]

How is a string represented internally in Flex?  It never actually says it
in the help for String.  Is it UTF-8?  I think this because because mxml
uses utf-8 as the encoding in the ?xml directive, ByteArray seems to treat
utf-8 specially, and ByteArray.readMultiByte says the return value is a
utf-8 encoded string.

The reason I ask is because I'm reading some string data in from a binary
file and I'm trying to figure out the most CPU efficient way to put it in
the file.  I want it to be in the file in the same encoding that won't
require Flex to translate from one encoding to another when storing it in a
String variable.

Thanks.

RE: [flexcoders] Overriding width of DateField

[Gordon Smith]

Try subclassing and overriding the measure() method to return a greater 
measuredWidth.

Subject: [flexcoders] Overriding width of DateField


One anomaly I've found in flex is the width of the DateField. It's
width is about 90px. If you use it with no width, and make it
editable, when the user puts in a date in mm/dd/ format it will
move the left 2 characters out of the box to the left.

To correct this issue, I would like to create a version of the
DateField and override the width, if not provided by the developer to
be 94px. I can easily do that by putting;

if (!this.width)this.width = 94;

in the initialize method. The problem is this does not display the
correct size object in flexbuilder during design mode.

My question is, how can I subclass the object in such a way as to have
it display properly (the enhanced width attribute) in design mode?

Re: [flexcoders] Re: how to add internal padding in canvas?

[Michael Schmalle]

The irony to all this over analyzation is;
We never heard the OP say WHY he even wanted to do this (padding in Canvas)
let alone if he even needed a canvas to do what he needed to do!

I just need to stay out of these application questions. ;-)

Tim, It is really exciting to see the future of flex and CSS.
I definitely encourage using things that deal with styles since the
framework is going to tip that way soon anyway. This is in reference to
using constraints.

I see loading style sheets as modules sooner than later. :)

You can find more by solving the problem then by 'asking the question'.

[flexcoders] Overriding width of DateField

[aceoohay]

One anomaly I've found in flex is the width of the DateField. It's 
width is about 90px. If you use it with no width, and make it 
editable, when the user puts in a date in mm/dd/ format it will 
move the left 2 characters out of the box to the left.

To correct this issue, I would like to create a version of the 
DateField and override the width, if not provided by the developer to 
be 94px. I can easily do that by putting;

if (!this.width)this.width = 94;

in the initialize method. The problem is this does not display the 
correct size object in flexbuilder during design mode.

My question is, how can I subclass the object in such a way as to have 
it display properly (the enhanced width attribute) in design mode?

RE: [flexcoders] Re: LCDS 2.6 and Hibernate - Does it work?

[Jeff Vroom]

We did rename some of the jar files so make sure you remove all of the old 
flex-messaging* jar files before copying in the new ones.  In particular 
flex-messaging.jar went away and is replaced by lots of smaller jar files 
flex-messaging-data.jar etc.   This was to implement the BlazeDS/LCDS split.

Thanks for the follow-up Jeff.

I couldn't even get the LCDS CRM sample to work. I will try again
with the log settings you suggested. If there's something suspicious
I'll post.

[flexcoders] Re: how to add internal padding in canvas?

[Tim Hoff]

I hear ya man.  Just like to keep things simple and, when possible,
allow for pulling the styles out to CSS.  I'm sure using a Box with
padding would work for this too; instead of having two containers.

[flexcoders] Re: sailorsea21 - RemoveChild question.

[sailorsea21]

Here's my updated code:

private var moduleloader:ModuleLoader;
private var unload_button:Button;   
private var vbox:VBox;
private var _aChildren:Array=[]; 

private function unloadclick(event:Event):void 
{
var iIndexClicked:int = parseInt(event.target.id);  
modulestile.removeChild(_aChildren[iIndexClicked]);
*error* modulestile.removeChild(event.target); *error*
}

public function AddColumnGraphPanel():void 
{
var iNewIndex:int = _aChildren.length;
vbox = new VBox();
modulestile.addChild(vbox);
moduleloader = new ModuleLoader();
moduleloader.url = "test.swf";
_aChildren[iNewIndex] = vbox.addChild(moduleloader);
unload_button = new Button();
unload_button.id = String(iNewIndex);
unload_button.label = "unload";
unload_button.addEventListener(MouseEvent.CLICK, unloadclick);
vbox.addChild(unload_button);
}

   
  

I have the following error in the script:
1118: Implicit coercion of a value with static type Object to a 
possibly unrelated type flash.display:DisplayObject.

Thanks again :)

[flexcoders] Re: LCDS 2.6 and Hibernate - Does it work?

[headjoog]

Thanks for the follow-up Jeff.


I couldn't even get the LCDS CRM sample to work.  I will try again
with the log settings you suggested.  If there's something suspicious
I'll post.

RE: [flexcoders] Re: Reusing HTTPService

[Jeff Vroom]

I do like this approach - that's what I do when I code using AsyncTokens.

In the SDK's trunk depot, we have implemented a different way of using the 
AsyncTokens which makes it easier to add per-call event listeners and result 
objects particularly from MXML.   It is in the class mx.rpc.CallResponder.  
Here's a sample of how you'd use it:





Each CallResponder monitors a single AsyncToken at a time and propagates its 
result and fault events to listeners on the call responder.  It also stores the 
lastResult property.  This allows you to cache the previous result while the 
next call is in progress.   Any feedback folks have on this approach will be 
appreciated.

I'll admit that modifying the token after the call was made is 
counter-intuitive.  It works because the AS VM cannot deliver any events on 
that token until after the current executing code path has completed.   We did 
consider passing in the token as an argument to the async calls but didn't 
think it really made things easier to understand and adds a risk that you'll 
use the same token for two simultaneous calls.

I like! This line says it all:

> service.send().addResponder(new MyIResponder(resultB, faultB));

Thanks much. I think this is the solution.

It meets my requirements: no long conditionals; one-to-one matching of
service calls to fault/result handlers; reuse of the same service
object; and, if i create a separate class (implemementing IResponder
and containing it's own fault and result handlers, rather than passing
it in as you've done) for each type of service call, i think i get to
live another day by the OO mantra "closed to modification, open to
extension".

Weird though how Flex requires one to add the responder after the call
is already made, don't you think? One would think the responder
should be in place before the call to service.send().

Thanks again!

Re: [flexcoders] Refreshing graphics in a tree

[ben gomez farrell]

Thanks!  You rock.  I'd never used setItemAt on an ArrayCollection 
because its more verbose to pull the copy the item out and set the 
property you need, then pass it back in - so it never occured to me that 
you had to do that.
Again, thanks, and i'll put the same fix on my list component.

RE: [flexcoders] Refreshing graphics in a tree

[Tracy Spratt]

Yes, this:
groupsdata.getItemAt(f).state = true/false
is a low-level assignment directly to the dataprovider item and does not
dispatch the events necessary for the update of the UI.

You can change it to use setItemAt() or you can call itemUpdated(item)
after the assignment.

I am sure both of these use the invalidation mechanism and optimize the
rendering.

I am not sure about refresh(), and that is not the correct usage anyway.

[flexcoders] Force compile of Modules

[Greg Hess]

Hi Folks,

I am having problems building my project that is divided into separate
modules. Compilation errors are not always reported. My main
application is just a module loader and I think that the compiler does
not 'always' detect changes in files/classes referenced in modules.
What happens is that my compile completes without errors but some(ones
with errors) of my modules are not compiled to a swf. I only detect
this when I run the application and see some of my modules are blank
or even worse the test runs with an old module and I am not even
executing latest code usualy discovered when a break point is never
reached... I then have to add an empty space in each of my module main
files to get them to recompile and get the error. I am using
FlexBuilder-Eclipse to build my projects.

This is obvously bothersome especially that last night I broke the
nightly build and had to buy donuts today ;-(. Last night I built,
deployed, tested and committed. If I had of done a clean build I would
have caught it...

Is there anyway to have fix with with compilier/module setting?

Any help much appreciated.

Greg

Something like this perhaps..

I'm assuming that the reason for the margin is to leave a gap around the 
edges. Lets say you want a 5 pixel gap.

Any good?

Maybe I've got the wrong idea about why you want the margin.

Re: [flexcoders] web compiler

[Matt Chotin]

The J2EE web compiler does this, the Apache/IIS ones don't.

In general we don't think that the web compilers get enough use to warrant our 
full-blown investment.  We're going to make sure that the source is available 
(should be in a few weeks for Apache/IIS and J2EE is already in Subversion), 
and we will do some amount of upgrading of the J2EE one.  But we probably won't 
expand the feature-set, and we will never consider them fully tested or 
performant enough to recommend for a production system.

But you'll only do the compile once  for each release, not once for each

Re: [flexcoders] Refreshing graphics in a tree

[ben gomez farrell]

I have an arraycollection called groupsdata
groupsdata.getItemAt(f).state = true/false

And then in my itemRenderer, I override like this:

override public function set data(value:Object):void {
super.data = value;
if ( !value ) { return; }
// remove check box from child nodes if present
if ( !value.toplevel && this.getChildByName("checkbox") ) { 
this.removeChild( this.getChildByName("checkbox") ); }
}

override protected function updateDisplayList(unscaledWidth:Number, 
unscaledHeight:Number):void
{
super.updateDisplayList(unscaledWidth, unscaledHeight);
if(super.data)
{
if (super.icon != null)
{
checkBox.x = super.icon.x;
checkBox.y = 12;
super.icon.x = checkBox.x + checkBox.width + 17;
super.label.x = super.icon.x + super.icon.width + 3;
checkBox.selected = super.data.state;
}
else
{
checkBox.x = super.label.x;
checkBox.y = 12;
super.label.x = checkBox.x + checkBox.width + 17;
checkBox.selected = super.data.state;
}
}
}

So it looks like the data object is getting set correctly, but 
updateDisplayList isn't getting called when the data is refreshed - but 
it does get called on mouse over.
thanks again for the help!

Re: [flexcoders] web compiler

[Michael Schmalle]

Ok,
I had this in my plans to investigate in a couple months for my server.

So is there something that caches swf on the first run, then only recompiles
when the mxml has changed?

Where did I hear that? This is in my head from a year or two ago.

RE: [flexcoders] Custom event - Create, dispatch, and listen to.

You should always override the clone() method in a custom event class that adds 
new properties. Otherwise, re-dispatching such an event (calling 
dispatchEvent(event) inside a handler for that event) won't work properly.

Hi,

Class names should begin with an Uppercase letter. RemoteClick not
remoteClick.
The type String can be lowercase if you want..

Something like the following..

package modulecode
{
import flash.events. Event;

public static const remoteClick: String="remoteCl ick";

public class RemoteClick extends Event
{
public function RemoteClick( type:String= "remoteClick" ,
bubbles:Boolean= false,

cancelable:Boolean= false)
{
super(type, bubbles, cancelable);
}
}
}

//Some component that dispatches and handles RemoteClick events



public function handleButtonClick( ):void{
var eventObj:RemoteClic k = new RemoteClick( ); //no bubble
dispatchEvent( eventObj) ;
}

public function handleRemoteClickEv ent(e:RemoteClic k):void{
trace("handleRemote Click: "+e);
}

public function init():void{
addEventListener( "remoteClick" , handleRemoteClickEv ent);
}








Or

//Some component that dispatches RemoteClick events. NOTE : the name of
the event and the type.



[Event(name= "remoteClick" , type="modulecode. RemoteClick" )]



public function handleButtonClick( ):void{
var eventObj:RemoteClic k = new RemoteClick( ); //no bubble
dispatchEvent( eventObj) ;
}








Use MyCanvas2 in another component..



function handleRemoteClick( e:RemoteClick) :void{ ... }

RE: [flexcoders] Refreshing graphics in a tree

[Tracy Spratt]

So how are you updating the dataProvider items with the checkbox state? 

 

Are you using the ArrayCollection API?  If so, then the UI will update
automatically.

 

Note: refresh() applies a sort.  It does not generically "refesh" the
UI.  Also, if you use the API, it should not be necessary to do anything
else for the list either.

If there isn't a mechanism for caching the compilation result (user requests 
mxml, but actually gets html/swf), performance in a production environment 
would be appaling. That wouldn't matter for development.

Re: [flexcoders] Re: how to add internal padding in canvas?

[Michael Schmalle]

Tracy,
Container::getScrollableRect():Rectangle

uses usePadding,

Dumb answer on my part. I had to subclass canvas where I actually wanted the
padding to count in the scrollRect.

Sorry for the noise, I'm thinking to much these days. I agree, from a design
perspective there is no need to do what I said.

But for the sake of an explanation, usePadding has to do with the
contentPane and how it gets shifted when there is scrollable content, so
overriding that would give you padding even though your component is at 0,0
in the contentPane.

[flexcoders] Re: Reusing HTTPService

[lagos_tout]

I like!  This line says it all:

> service.send().addResponder(new MyIResponder(resultB, faultB));

Thanks much.  I think this is the solution.  

It meets my requirements: no long conditionals; one-to-one matching of 
service calls to fault/result handlers; reuse of the same service 
object; and, if i create a separate class (implemementing IResponder 
and containing it's own fault and result handlers, rather than passing 
it in as you've done) for each type of service call, i think i get to 
live another day by the OO mantra "closed to modification, open to 
extension".

Weird though how Flex requires one to add the responder after the call 
is already made, don't you think?  One would think the responder 
should be in place before the call to service.send().

Thanks again!

Subject: [flexcoders] How to display message in empty Tree component

 


I'm using a Tree component with a dataProvider set using an XML object.
Also
showRoot=false.

If I set using a childless XML object then one item is shown in the
tree.
That's a bit weird but it sort of allows me a way to display my message
(using labelFunc) to "No items". But then I have to be careful with all
my
event handlers because this item is not really a real item for my
purposes.

However, if I use an XML with, say, one child, then that child is
displayed.
If I then remove that child, then nothing is displayed (and so I see no
way
to display the message).

What is the best way to display a message (like "No items") in the Tree

RE: [flexcoders] Refreshing graphics in a tree

[Tracy Spratt]

How are you updateing the dataProvider?  If you use the correct API, the
changes should reflect automatically.  If you are using lower level
assignments, then you might need to call itemUpdated for collections.

 

What is your dataprovider?

Subject: [flexcoders] Refreshing graphics in a tree

 

Hey, I have a tree with a itemRenderer to have a clickable checkbox in 
it. I need to set the checkbox state sometimes through code. 
Everything works great, except the graphics of the checkbox don't update

when it's set through code (mousing over the node will refresh the
graphics)
Is there a way to refresh the graphics of all the nodes through some 
method of the tree? I CAN open and close the nodes to refresh the 
graphics, but it seems really silly, and I have to track whats open and 
closed and make sure it gets back to the same state again.

Thanks!

RE: [flexcoders] Re: how to add internal padding in canvas?

[Tracy Spratt]

Hold on a minute.  Canvas uses absolute positioning.  So "padding" would
only affect percentage resizing?  And 0,0 would still be top left
corner, regardless of the padding?

 

This seems kind of confusing.  I'm with Tim, and think this would be
better solved with constraints.  I suppose you could declare Spacers of
height="100%" and whatever width you wanted, and position them with
constraints.

Another alternative, if you have to use a Canvas and don't want to
subclass, is to use constraints (top, bottom, left, right) on the
children.

RE: [flexcoders] Re: sailorsea21 - RemoveChild question.

[Tracy Spratt]

That is correct, you are not storing references correctly.  First I will
explain what is wrong with your code, but then, after seeing what you
are trying to do, will suggest a slightly different approach.

 

First, you are mixing Array, which is accessed by index and "associative
array", which is an Object and accessed by property name:

private var _oChildren:Object = new Object();

 

Second, you are creating a new instance of that each time you click
addModule.  This overwrites what was in there before.  Don't do that.

 

Third, you need a unique name for each reference you add to the
associative array.  Don't use "one" every time, that just puts a new
reference in the "one" property.  You can use anything you want for this
property name.  Pick something that is meaningful.  How will you
identify which child you want to remove?  Is it purely numerical? If so
you can use "1", "2", etc.  Usually there is some string that is logical
for this, like an id, or an image's base file name.  whatever, remember
it must uniquely identify the instance you want to later remove.

 

Now, after looking at your code a bit more, and seeing that you do not
have a clear string or id you can use for identifying the references, I
am gong to suggest a different approach.

private var _aChildren:Array= [];   //declare an initialize
an Array

 

...

public function addModule():void {
  var iNewIndex:int = _aChildren.length;  //this will be the next
available index in the array

  button = new Button();

  button.id = String(iNewIndex);   //NOTE: you can NOT use this id as a
reference, but you CAN access its value
  button.label = "unload";
  button.addEventListener(MouseEvent.CLICK, onClickUnload);
  tiletest.addChild(button);  

  moduleloader = new ModuleLoader();
  moduleloader.url = "test.swf";
  _aChildren[iNewIndex] = tiletest.addChild(moduleloader);  //NOTE: the
associated button id property value matches the index of the array ref
}// addModule

 

private function onClickUnload (event:Event):void {
  var iIndexClicked:int = parseInt(event.target.id);  

  tiletest.removeChild(_aChildren[iIndexClicked]);
  tiletest.removeChild(event.target);
}// onClickUnload

 

Try this.  it is untested.

 

Tracy

Hi Tracy, 

I don't think I'm successfully storing the reference of the children 
into the array. 

This is what I had tried:

private var moduleloader:ModuleLoader;
private var button:Button;
private var _aChildren:Array;

private function click(evt:MouseEvent):void {
tiletest.removeChild(_aChildren["one"]);
tiletest.removeChild(button);
} 

public function AddModule():void {
moduleloader = new ModuleLoader();
moduleloader.url = "test.swf";
button = new Button();
button.label = "unload";
button.addEventListener(MouseEvent.CLICK, click);
tiletest.addChild(button);
_aChildren = new Array();
_aChildren["one"] = tiletest.addChild(moduleloader);
} 

But I keep getting the "ArgumentError: Error #2025: The supplied 
DisplayObject must be a child of the caller." error.

Thanks again.

RE: [flexcoders] Re: FZip loads cached zip before downloading online

[Kevin Benz]

When you destroy the FZip object, don't necessarily know and if you
don't know, you have to clean up after yourself. Remember, when you use
HTTP, you are subject to timeouts that may or may not expire as you
expect them let alone the myriad of other errors along the way
(permissions, server error, etc). If you only wait for a Complete event,
then the HTTP object is left hanging and the file is certainly in a
dirty state as well.

[flexcoders] Re: FZip loads cached zip before downloading online

[diigiibot]

Well, it looks like it is valid. 
When it starts to unzip the zip in the temp folder I get the 2 first
folders in it. So that doesn't give me an IOError. 
I also tried to compare the number of files in the local zip with the
one online(just with a hardcoded var) but that puts me in a loop where
he keeps extracting the zip over and over.

RE: [flexcoders] LCDS 2.6 and Hibernate - Does it work?

[Jeff Vroom]

We did change from hibernate 3.1 to 3.2 in LCDS2.6 but otherwise I don't know 
of any compatibility problems introduced.   We did that primarily so we could 
support the hibernate JPA annotations and there might have been a tweak or two 
to the hibernate assembler to get it to work in that environment.

A good first step to diagnosing your problems would be to turn on the debug 
logging (in services-config.xml, set level="Debug" and makes sure Service.*, 
Configuration and Message.* are in the patterns below).From those logs we 
can probably get a clue as to what is going on.  If they are large, feel free 
to send them to me offlist: [EMAIL PROTECTED].

Hi -

I tried upgrading from LCDS 2.5 to LCDS 2.6. I have a project using

Has anyone else tried this? Or is there anything from Adobe on

[flexcoders] Re: Need help for mx:MenuBar?

[valdhor]

I don't understand what you want. Do you want the menu to drop down
when you mouseover it or when you click it?

Have you checked out the example at:

[flexcoders] Re: how to add internal padding in canvas?

[Tim Hoff]

Another alternative, if you have to use a Canvas and don't want to
subclass, is to use constraints (top, bottom, left, right) on the
children.

[flexcoders] Alex Blog: Datagrid Column Header and ComboBox

[ilikeflex]

Hi Alex

I looked through your blog. I implemented below functionality
http://blogs.adobe.com/aharui/ComboBoxHeader/dg.swf.

Now if i want to show that as soon as the datagrid loads, combobox
shows "Below 40" and data is also sorted. I want to change the item in
combo box. How to do that?

Any pointer is highly appreciated.

Thanks

[flexcoders] Re: sailorsea21 - RemoveChild question.

[sailorsea21]

Hi Tracy, 

I don't think I'm successfully storing the reference of the children 
into the array. 

This is what I had tried:

private var moduleloader:ModuleLoader;
private var button:Button;
private var _aChildren:Array;

private function click(evt:MouseEvent):void {
tiletest.removeChild(_aChildren["one"]);
tiletest.removeChild(button);
}   

public function AddModule():void {
moduleloader = new ModuleLoader();
moduleloader.url = "test.swf";
button = new Button();
button.label = "unload";
button.addEventListener(MouseEvent.CLICK, click);
tiletest.addChild(button);
_aChildren = new Array();
_aChildren["one"] = tiletest.addChild(moduleloader);
}   

But I keep getting the "ArgumentError: Error #2025: The supplied 
DisplayObject must be a child of the caller." error.

Thanks again.

Re: [flexcoders] Module Interfaces Inheritance question

[Purushottam Yeluripati]

Ralf,
   I tried to include all the common classes into a library which is linked 
into the main application, but that did not resolve it. I tried the option of 
loading all the modules into the main application's ApplicationDomain. No luck 
still. But now the module is not able to get a handle to the parentApplication 
instance. It throws a null reference or property access error in the getter for 
the parent Application.

It has to do with the ApplicationDomain. Unless otherwise specified, a
module lives in its own ApplicationDomain. This way it can have its
own copies of every class. If you load the modules into the same
ApplicationDomain as the main application, the warning should be gone
as well. Its just, in this case the classes are still included in all
of the modules.

RE: [flexcoders] Re: Flex uploader / accessing local files?

This actually isn't very tough at all. You need to get the File object,
load its  BitmapData and use the Matrix object to size it and then
either PNGEncode or JPGEncode back out.

[flexcoders] Listen to transition complete?

[Christoph Leva]

Hi all,

is it possible to add an eventListener, that listens for the end of a
transition between two states? Couldn't find anything.

Don't want to listen to a stateChange Event and don't want to use a timer,
that sends an TimerEvent.TIMER_COMPLETE after the duration of the
transition.

Thanks, Chris

Scratch my last comment btw... duh... when you're not connected you  
have no idea if it's been completed.


What you can do is see if FZip will open up the ZIP archive that  
didn't download completely. You should have an error thrown that it's  
not valid because, well, the ZIP archive wouldn't be valid if it's  
not fully downloaded.

Re: [flexcoders] how to add internal padding in canvas?

[Michael Schmalle]

A hack that can be done if you really want Canvas is;
Create a subclass of Canvas and override the usePadding property.

override mx_internal get usePadding():Boolean
{
return true;
}

This will turn the padding back on when the
layout calculates viewMetricsAndPadding.

Re: [flexcoders] Re: Extending UIComponent memory issues.

[Michael Schmalle]

Jason,
What I suggested is probably a bit to complex for what you need. It's kind
of a reimplementation of what you are doing.

1. Subclass UIComponent to make your container.
2. Create the layout algorithm in that component.
3. Create a subclass of FlexSprite that is your loader component.
4. Add the FlexSprite subclass instances (your content) to your UIComponent
container class with custom layout.
5. Add the UIComponent class to a Container.

The above is not really a solution for you right now I'm sure, I was just
saying this is what I would do to get maximum performance and memory
management.

The reason I say this is I have no idea how you are laying out those
instances with reflection etc. How are you laying them out (with what layout
algorithm) ?

Right, i see.  :)

Yep. You use that metadata tag when you want to expose the event to a 
container component via mxml
(Eg.)

If you look at the source of mx:Button you'll see the metadata for the 
click event.

I wasn't sure if you knew that so i didn't comment on it.

So you would use the metadata tag if you wanted to do the following.




  private function handleFormSubmitted(e:CustomEvent):void {...}






MyComponent would have the metadata tag declaring the name and the type 
of the event it dispatches and then it appears in FlexBuilder as a hint.

This is pretty much the same as writing the following:
mc.addEventListener("formSubmitted", handleForSubmitted);

HTH.

I'd look at the Button code and see how it uses stateful skins.  And 
I've found that using styles for this kind of thing works pretty 
well.  You can either extend TileList to pass through the appropriate 
style into the component or you can look at my TileList_withStyle 
component, available at http://flexdiary.blogspot.com.  Or you can 
just change the style declaration for your custom component on the 
fly to change the applicable style/state at runtime.

Re: [flexcoders] Module Interfaces Inheritance question

[Ralf Bokelberg]

It has to do with the ApplicationDomain. Unless otherwise specified, a
module lives in its own ApplicationDomain. This way it can have its
own copies of every class. If you load the modules into the same
ApplicationDomain as the main application, the warning should be gone
as well. Its just, in this case the classes are still included in all
of the modules.

Re: [flexcoders] custom event not working in popup

[hoz]

Hey Shaun,

Thanks for the reply, and YES, it finally worked. It's always those little
typos that gotcha's!! The $'s were just taken from code relating to PHP
format; obviously, not needed.

I did find it interesting that I could also do this and skip the metadata
tag in the popup:

application.systemManager.addEventListener(CustomEvent.ON_TEST_CASE,handleUpdateFormSubmitted);

not sure if that's bad practice, but we have finally solved the popup window
to main scenario!!

RE: [flexcoders] FZip loads cached zip before downloading online

[Kevin Benz]

Not sure exactly what is happening but  I suggest an improvement to your
approach.

 

You should detect the change in network connection status and use that
event to flush any objects that are waiting on an event to fire. AIR
fires a NETWORK_CHANGED event and I would make sure you clean up your
objects at that point.  You cannot depend on the quality of the bits you
just downloaded regardless and need to re-enter the  process.

Subject: [flexcoders] FZip loads cached zip before downloading online

 

I'm using FZip in an AIR application, the application loads the zip
from a location on our server, unpacks the zip and move the files to
their local folder. Everything runs smooth until I cut off my internet
connection while the zip is downloading.
When I restart the application it looks like FZip is first checking
the temp folder for the cached zip and if found, it uses that one to
unzip, even if the zip was not completed the last time.

Does anyone know of a way to prevent that?

I use the default load method of the FZip library, this is a part of
the code I use.

var moduleLink:String = [EMAIL PROTECTED];

var zip:FZip = new FZip();

zip.addEventListener(Event.COMPLETE, onComplete);

zip.load(new URLRequest(moduleLink));

private function onComplete(evt:Event):void 
{
var moduleDir:File =
File.applicationStorageDirectory.resolvePath("modules");

var outStream:FileStream;

You are dispatching an even with a "type" String value of
"formSubmitted" and listening/registering for "formUpdate".
Change the event constant to "formUpdate" and it will work again..


[Event(name="formUpdate",type="com.event.CustomEvent")]


MAIN APP
application.systemManager.addEventListener("formUpdate",handleUpdateFormSubmitted);


// event constants
public static const ON_TEST_CASE:String = "formSubmitted";

new CustomEvent(CustomEvent.ON_TEST_CASE,
 {
 memberID:memberID_txt.text
 }
 );
  this.dispatchEvent(evt);


By the way, whats with the $ signs in the arg names?

Are you sure you are listening for the same event type in main? From what I can

Re: [flexcoders] Re: Reusing HTTPService

[shaun]

How about something like this:

(note: I've not tried it, just slapped it straight into the email)

public class MyClassThatInvokesHTTPServices {

//inner helper class.
class MyIResponder implements IResponder{
   public var f:Function;
   public var r:Function;

   public MyIResponder(r:Function, f:Function){
 this.r = r;
 this.f = f;
   }

   public function fault(info:Object):void {
   f.call(info);
   }

   public function result(result:Object):void {
   r.call(result);
   }
}

//Your handlers for service calls.
protected function resultA(result:Object){ ... }
protected function faultA(info:Object){...}
protected function resultB(result:Object){ ... }
protected function faultB(info:Object){...}

var service:HTTPService ...//assume exists, reused for various calls.

  //send for service A.
  funciton sendA(args:Object){
service.url = "../A.html";
service.send(args).addResponder(new MyIResponder(resultA, faultA));
  }

  //send for service B.
  function sendB(){
service.url = "../B.html";
service.send().addResponder(new MyIResponder(resultB, faultB));
  }


}

[flexcoders] Re: adding the user input to an arraycollection

[valdhor]

This is how I would do it (Others may do it differently)...

Assuming the text fields have id's of bookType and sales:

private function addToArray():void
{
 var newBook:Object = new Object();
 newBook.bookType = bookType.text;
 newBook.sales= bookType.sales;
 bookSales.addItem(newBook);
}

Re: [flexcoders] Rippling through state changes

[Johannes Nel]

this is also a nice way to test around the presentation model pattern, your
pres model exposes the state the view should be in and dependent on what the
data state of your pres model is in
