[flexcoders] Re: Binding behaviour

[turbo_vb]

I have to disagree.  If a child property is a class or a collection, you will 
be setting a reference to the same objects in the cloned parent.  Thus, updates 
to the child property will be made to both the clone and the original.  
ObjectUtil.copy() is another good way to clone, but does not always work for 
deeply nested objects.

[flexcoders] Re: ModuleLoader.child is null

[turbo_vb]

Perhaps you're getting an error on load; probably due to the path.  Try adding 
an event listener for ModuleEvent.ERROR.

Also, this line is missing an equal sign:

var test:ITest ITest(this._moduleLoader.child);

Should be:

var test:ITest = ITest(this._moduleLoader.child);

[flexcoders] Re: Binding behaviour

[turbo_vb]

If nodeName is a class, you'll need to create a clone method in that class as 
well, and do this:

obj.nodeName = nodeName.clone();

If it's just a string, you can try:

obj.nodeName = nodeName.toString();

Try sticking that in override prepare() or set data(), and make sure that data 
isn't null, and I bet you that it'll work.

[flexcoders] Re: right align the gridcolumn text

[turbo_vb]

ClassFactory doesn't support setting styles; they're different than properties. 
 You can get around this by either:

1) use a custom item renderer that has a styleName or css selector.

2) extend ClassFactory to support setting styles on the item renderer 
instances.  See com.blogagic.core.UIComponentFactory at 
http://blogagic.com/_flex/libagic_source/srcview/index.html

[flexcoders] Re: Flex 4: MouseOver not firing on a UIComponent Item Renderer

[turbo_vb]

It doesn't seem that skinning is something that Adobe considered would need to 
be done in a skin class, for an item renderer.  But, you can apply a skin class 
to them if desired.  At each level: GroupBase, Group, DataRenderer, and finally 
ItemRenderer, you get additional functionality; and consequently, a little more 
overhead.  For instance, if you used ItemRenderer instead of UIComponent, you 
could use the "hovered" state to control the visibility of the button.  
However, I think that you're going about it the most efficient way in creating 
AS item renderers instead of mxml; especially for ADG.

[flexcoders] Re: Why don't horizontalCenter and verticalCenter work with Spark ColumnConstraints?

[turbo_vb]

Ok, that makes a little more sense now.  It can still work, but instead of 
moving the boxes, during transition, move the groups; and resize the boxes 
within the groups.  As an alternative, you could choose to use a custom layout 
class.

[flexcoders] Re: Why don't horizontalCenter and verticalCenter work with Spark ColumnConstraints?

[turbo_vb]

Constraints are designed to be used to constrain other components for things 
like alignment and size.  For your app, just add a group around each of your 
containers and you're fine.

[flexcoders] Re: Best Practice for Subclassed UIComponent and DataProvider

[turbo_vb]

Back to your problem.  If you're not seeing the combo box's dataProvider 
populate or update, then it's a binding problem.  Good idea to try the 
BindingUtils, but it's easier to fix the binding events in the model.  If 
you're using a getter / setter in the model, for the facilities collection, 
make sure that the binding event is dispatched in the setter.  If you're not 
seeing the collection update, when existing items have been changed elsewhere, 
then listen for the COLLECTION_CHANGE event on the facilities collection, and 
in the listener function, manually dispatch the collection's binding event 
(same as the one in the setter).  If this doesn't work, look further upstream; 
in the service, delegate or controller.  You'll find the short.

[flexcoders] Re: How to call container's method into component file

[turbo_vb]

That's bad advice Rishi; that leads to tight coupling and "parent abuse".  It's 
ok to have a parent call a method on a child ( data binding is preferred 
though).  But, children shouldn't call methods directly on their parents.  
Instead, have the child component dispatch an event to initiate the save method 
on the parent.

[flexcoders] Re: Best Practice for Subclassed UIComponent and DataProvider

[turbo_vb]

You have the right idea; to encapsulate the dataProvider, validation and change 
event handler.  But, instead of putting them inside the control, wrap all of 
that into a common facilities model, that gets used anywhere it's needed in the 
application.  I stopped using Cairngorm a long time ago, but hopefully the 
newest version supports dependency injection; so you can just inject a 
reference to the facilities model where needed, and hook it up to the combo 
box.  That would be best practice.  But, at the end of the day, the goal is to 
make it work, so...

[flexcoders] Re: Best Practice for Subclassed UIComponent and DataProvider

[turbo_vb]

Validation can be abstracted just like dataProviders.  For a combo box, you 
only need to validate the selectedItem; from the view, presentation model, or a 
common utility class.  Most other stuff happens in itemRenderers; that have a 
little more freedom.  It may be that you're locked into a structure that was 
handed to you, but hardcoding a reference to a singleton model, from which you 
set the data provider of a combo box from within the combo box, breaks the 
rules.  If you're having problems with binding the dataProvider to the model's 
property, the binding problem is probably upstream from the combo box.  Good 
luck Shawn, just trying to help.

Can't see any good reason to subclass a control in order to hardcode the 
dataProvider.  The idea is to keep the components loosely coupled.  Are you 
having a problem with dataProvider="{model.facilities}"?

If you're using Flex 4.5, something like this works:

var myClassObject:Object = new MyClass();
var classInfo:XML = describeType( myClassObject );
var propertyType:String;
var propertyName:String;

for each ( var property:XML in classInfo..accessor )
{
propertyName = property.@name;
propertyType = property.@type;
}

[flexcoders] Re: Method for a Datagrid Button Itemrenderer

[turbo_vb]

Hi Angelo,
You're close.  You'll need to declare the event in the DataGrid.  A
simple subclass should do the trick.  This way you can add the event
listener in mxml too:

package myPackage

{

import mx.controls.DataGrid;




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




public class MyDataGrid extends DataGrid

{




}

}

[flexcoders] Re: Flex 4 data management - how do I approach this?

[turbo_vb]

Hi Henrik,
So you're getting back a collection of products from the service and
binding them to the DataGrid.  Let's assume that the product objects are
Product Value Objects.  You have every thing that you need for an order
except for the quantity of the product(s) to order.  Keep it simple, add
a Transient field to the Product VO and use that for the quantity column
in the same DataGrid.

[Transient]

/**

* The product quantity to order

*/

public var productQuantity:int = 0;




The itemEditor in the DataGrid can then just update the quantity
property directly in the Product VO.  The next step is to take the
Product(s) that have a quantity and submit them to become an order. 
Usually the user can select multiple products for an order, so I'll go
that route.  After the user has entered all of the product quantities to
order, the Products in the ArrayCollection are ready to be processed
into an order.  The user clicks a submit button; or you do this when the
individual quantities change.  For each (or one)  Product in the
ArrayCollection that has a quantity > 0, create an OrderDetail VO from
the necessary Product properties; including productQuantity.  You might
prefer OrderContent VO since that's the table that you're updating on
the server.  Add the OrderDetail VOs to an ArrayCollection and send the
collection to the service; to process and create an order.  Or, you can
send a single VO; if that fits your needs better.  The php service can
create the order and then add the details to the order from the
submitted collection of  or single OrderDetail DTO.  That's a simple
round trip.  Good luck.

[flexcoders] Re: Could not resolve * to a component implementation.

[turbo_vb]

The point is that creating 2 files in the same folder, with the same 
case-sensitive name, is ambiguous.  When you import one of the files into a 
component, how do you suppose that the compiler would know which one to use?  
It doesn't matter if its a file or class or interface or whatever.  The 
compiler can't read your mind; yet :)  Your approach of abstracting the view 
script code out of the view is a good idea; especially for unit tests.  Just 
use a different name and you'll be fine.

Probably no more elegant, but an alternative:

package

import mx.core.mx_internal;




use namespace mx_internal;




public class DeadButton extends Button

{

public function DeadButton()

{

super();




mx_internal::overSkinName = "upSkin";

}

}

}

Another alternative would be to extend ArrayCollection, or whatever collection 
type desired, with a status property.

[flexcoders] Re: Mate: listener injector vs manager/PM binding

[turbo_vb]

I agree, but it can; since the map knows about the PM anyway.  This is where 
Swiz has an advantage with the Mediate metadata.  In that case the PM method 
can just listens for an event; which can be dispatched on fault.

I usually use (b).  For the error, you can call a public method in the PM from 
the faultHandler in the map; as one alternative.

[flexcoders] Re: Could not resolve * to a component implementation.

[turbo_vb]

Glad that you were able to resolve the problem.  The AS file IS a class, and if 
it lives in the same package as the mxml component, the compiler will balk; 
because it doesn't know which one to import elsewhere.  Adobe best practice 
would have you use Uppercase for the first letter of all classes.  Renaming the 
script class to something like FooScript.as or FooModel.as might be a better 
way to go.

[flexcoders] Re: Could not resolve * to a component implementation.

[turbo_vb]

A couple things that you can check that might help:

•   Make sure that you have an import statement for the component 
in the parent class.
•   If your component is an AS class, make sure that the package, 
at the top of the class, is correct.
•   If your component is an AS component make sure that the class 
name, within the component, is correct.  If you are using a constructor check 
that too.

Actually, you weren't wrong.  It seems that if you use [Bindable], the compiler

The example does compile and the binding works; even when you remove the 
injected dispatcher.  Kind of stumped on why this works in a class that doesn't 
extend EventDispatcher.

Hey Steve,

The component that Marco is referring to is not a UIComponent, so it doesn't 
have a dispatchEvent() method.  He'll have to change thel class to extend 
EventDispatcher.

[flexcoders] Re: dispatchEvent import

[turbo_vb]

Hi Marco,
That does look like a problem.  The dispatchEvent() method is available
for any UIComponent subclass or any class that extends EventDispatcher. 
So, if you're going to use [Bindable] properties in the presentation
model, you would want to have the PM extend EventDispatcher:

import flash.events.EventDispatcher;




public class UserPresentationModel extends EventDispatcher

{

private var _currentState : String;





[Bindable( "currentStateChanged" )]

public function get currentState() : String

{

return _currentState;

}




public function set currentState( state : String ) : void

{

_currentState = state;

dispatchEvent( new Event( "currentStateChanged" ) );

}


}

This will allow you to bind the property to a view.
For events that you want to [Mediate], you would use the injected
dispatcher:

[Dispatcher]

public var dispatcher:IEventDispatcher;




dispatcher.dispatchEvent( new Event( "myEvent" ) );

[flexcoders] Re: Setting UI components in a composite component to private?

[turbo_vb]

Hi Nick,

The best option is to create your composite components in Action Script.  This 
gives you direct control over the scope of the children, and they can be 
referenced within the component by the name of the var.  For MXML composite 
components, if you don't give the children id's, they won't be public.  This 
can be tricky if you're used to referencing the children inside the component 
by their id's, but you can usually rework logic like that to rely on events, 
like click and change, instead of references; since events have a reference to 
the target or currentTarget.

[flexcoders] QTP Automation and Custom Flex CheckBox itemRenderer

[turbo_vb]

Using QTP 10 and SDK 3.5 and having a tough time figuring out how to record and 
play back the "click" event of a extended CheckBox itemRenderer in an extended 
DataGrid component.  I've tried different combinations of custom automation 
delegates and class definitions file properties, for the itemRenderer and the 
DataGrid, but haven't found a solution yet.  Other custom components have been 
instrumented successfully, but no love for the itemRenderers. Anyone else run 
into this problem?

[flexcoders] Re: How to find the Value of a Property in the Last Object of An Array Collectio

[turbo_vb]

If you keep the id's in sync with the index values of the ArrayCollection you 
can just use:

linksFullAC.addItem({linkid:linksFullAC.length, label:userenteredlabel.text});

[flexcoders] Flex 4 State Names and Binding

[turbo_vb]

Hi All,

Unlike Flex 3, it seems that Flex 4 doesn't allow state names to be bound to 
constants anymore.  An example that no longer works would be something like 
this:



While I appreciate the improvements that have been made to Flex 4 states, this 
can be a problem for MVC oriented navigation frameworks.  Just wondering what 
the rational was for making this change.

Thanks,

[flexcoders] Re: Positioning / Scrolling problem with Flex popup

[turbo_vb]

You'll want to create a method that does something like this:

var target:Point = localToGlobal( new Point( hbox.x, hbox.y ) );
popup.move( target.x, target.y );

Call the method after you add the popup and when the container is scrolled.  In 
some cases localToContent is more appropriate.

[flexcoders] Re: A Viewstack but not with Canvases

[turbo_vb]

Hi Leonardo,

ViewStack requires its children to be a Container, or subclass of Container.  
Box, HBox and VBox all extend Container and should work just fine.  Besides, 
you're talking about adding a sibling to your current app.  So, you could wrap 
the code for your current app into any Container; the children don't matter.

[flexcoders] Re: Handling dataProvider of ComboBox on another navigatorContent

[turbo_vb]

An easier approach than using these events, is to bind the ComboBox 
selectedIndex property to a variable like: [Bindable] public var 
myComboBoxSelectedIndex : int; that lives in the same class as the data array.  
When you get or initialize the array, set the variable to the desired value, 
and the binding will automatically display the correct item in the ComboBox.  
This way, you don't have to worry about timing.  If the ComboBox exists, when 
the variable changes, the selectedItem will change then.  If the ComboBox 
doesn't exists when you set the variable, when the ComboBox is instantiated the 
binding will kick in then.

[flexcoders] Re: Scale 9

[turbo_vb]

Scale 9 has nothing to do with the position of the image.  You would use the 
normal properties for that ( top, bottom, left, right ).  What scale 9 defines 
is the portion of the image to stretch when the dimensions of the image are 
changed to be bigger than the original image size.  So, if you look at the 
sample in your link, the blue rectangle in the very center is what will be 
stretched.  The rest of the image ( the fancy corners ) will remain unchanged.

[flexcoders] Re: ViewStack and CreationComplete...

[turbo_vb]

Hey Laurence,

When ViewStack children are instantiated the creationComplete event is 
dispatched, but not the show event.  So, if you navigate to the second 
ViewStack child, the first time, you'll only get creationComplete.  After that, 
when you navigate to the second child the show event will be dispatched; from 
the second child's top-level container.  Usually, if you need to do something 
regardless if its the first, or subsequent, times that you navigate to a child, 
you have to listen for both events.

[flexcoders] Re: Twitter Feed Within An Air/Flex Application

[turbo_vb]

Polling the twitter service every 60 seconds (refresh) would be a way
that you could get updates semi-automatically.  You're not using RTMP,
so you're never going to be really live.   HTTPService calls are
asynchronous, so there isn't much overhead just listening to a Timer().
For extending the functionality, here's a couple links.

Hi James,

If your application automatically displays new tweets, those created after the 
initial load, than yes; that would be considered "live".  If however its just 
taking a snapshot, then no.  A starting point would be to "refresh" the tweets. 
 Having the ability to post tweets, and see them instantly show up, would also 
make it more live.  Other ideas would be IM, chat, or other real-time 
activities that involve the course; like live test scoring, or something.

Re: [SPAM] [flexcoders] Obtaining rendered text from a DataGrid

[turbo_vb]

If you don't have too many items in the dataProvider, you could create a second 
DataGrid, with the same DataProvider and itemRenderers, that does not have a 
height set and is not visible.  The second DataGrid would render all of the 
items in the dataProvider, because the height isn't set.  Then go about 
inspecting the itemRenderers like you proposed earlier; to get the data for 
your service call. Not the best solution, but this is an unusual use-case.

Three time's a charm:

var series:LineSeries = LineSeries( o.element );
var seriesIndex:int;

for ( seriesIndex = 0; seriesIndex < myChart.series.length; seriesIndex++ )
{
var lineSeries:LineSeries = myChart.series[ seriesIndex ] as LineSeries;

if ( lineSeries == series )
{
break;
}
}

So, maybe something like this:

private function dtFunction( o:HitData ):String
{
var series:LineSeries = LineSeries( o.element ) as LineSeries;
var seriesIndex:int;

for ( var a:int = 0; a < myChart.series.length; a++ )
{
var lineSeries:LineSeries = myChart.series[ a ] as LineSeries;

if ( lineSeries.displayName == series.displayName )
{
seriesIndex = a;
break;
}
}

var s:String = "" + LineSeries( o.element ).displayName + "\n";
s += "Books: " + LineSeriesItem( o.chartItem ).yValue + "\n";
s += "Book rate: " + o.item.session[ seriesIndex ].bookrate + 
"\n";
s += "Status: " + o.item.session[ seriesIndex ].status + "\n";

[turbo_vb]

Easy enough, create a dictionary (id or name) when the series's are created; 
with the index.  And/Or you can get the count from myChart.series.length.

Ok, good.  Not sure exactly what you're trying to do, but it's basically the 
same type of thing as the data function.  It's all about getting to right data 
for the series.  Here's some code for getting individual values and for 
calculating totals for the week

private function dtFunction( o:HitData ):String
{
var seriesId:String = LineSeries( o.element ).id;
var seriesIndex:int;

switch ( seriesId )
{
case "s0":
seriesIndex = 0;
break;
case "s1":
seriesIndex = 1;
break;
case "s2":
seriesIndex = 2;
break;
default:
break;
}

var totalBooksForWeek:int = 0;

for ( var a:int = 0; a < 3; a++ )
{
var sessionBooks:int = o.item.session[ a ].books;
totalBooksForWeek += sessionBooks;
}

var s:String = "" + LineSeries( o.element ).displayName + "\n";
s += "Books: " + LineSeriesItem( o.chartItem ).yValue + "\n";
s += "Book rate: " + o.item.session[ seriesIndex ].bookrate + 
"\n";
s += "Status: " + o.item.session[ seriesIndex ].status + "\n";
s += "Total Books for All Sessions: " + totalBooksForWeek + "\n";

return s;
}

[flexcoders] Re: Displaying additional child nodes in Datatip

[turbo_vb]

Assuming that you have assigned an id to each series
("baseline","2009-8"), you could use something like this:

private function dtFunction( o:HitData ):String

{

  var index:int = ( LineSeries( o.element ).id == "baseline" ) ? 0 :
1;

  var s:String = "Book rate: " + o.item.session[ index
].bookrate;

  return s;

}

[flexcoders] Re: Displaying additional child nodes in Datatip

[turbo_vb]

Yeah, you're very close.  Now it's just a matter of xml.  I'd start by tracing 
o.  If the children are still in o, then drill down.  Otherwise, you'll have to 
go and find the nodes; like you're trying below.  Some things that you can 
start with:

trace( o.toXMLString() );

var myXMLChildren:XMLList = o.children();

o.child("myProperty")[0].valueOf();

[flexcoders] Re: Displaying additional child nodes in Datatip

[turbo_vb]

If the dataTipFunction doesn't give you enough flexibility, you could try a 
dataTipRenderer.  In either case, you can drill down to the child nodes there.

[flexcoders] Re: Updating renderer properties

[turbo_vb]

We're not so off really, I hear what you're saying.  Now we're getting a better 
idea of the use-case.  In this case, all of the itemRenderers need to be 
controlled the same way; by changing their styles and/or labels.  So let's go 
up a level.  Extend the List, or whatever.  Both the dataProvider and the 
collection of itemRenderers are there, so you could do it either way from the 
parent.  For the styles, I'd still try the StyleDeclaration routes.  For the 
labels, you have to ask, are the labels data related, like from a table 
somewhere?.  Are they related to the parent object of the data in the 
dataProvider?  Or, are they constants or persisted values?  Each case could 
have a different solution.   One way, is to create a public var in the 
itemRenderers, or a getter/setter, if you want to do something when the value 
changes.  So, the itemRenderer's label.text is bound to the public var.  In the 
extended list you create a method to update all of the public vars in the 
itemRenderers.  It's a loop, but not so bad.  Make your extended List's method 
public.  Or, you can also use getter/setter vars, if you wanted to bind out 
further.  When set, they could trigger the method that updates the 
itemRenderers.

Or, you can always use "owner as List," in the itemRenderer to check the value 
of a public var in the parent List during updateDisplayList(), and set your 
label's text value there. 

Like I said, it's usually all about the use-case.  In general, I don't see a 
lot of itemRenderers that all display the same thing; unless the data happens 
to be identical.  Common labels are often pulled up to the parent component.  
And the manipulation of an itemRenderer, for me, is usually based on data 
properties; that make sense to be included in every item.  Interesting 
discussion.

[flexcoders] Re: Updating renderer properties

[turbo_vb]

Sure, but you don't necessarily need a model to use a VO; it can just be the 
strongly typed object that the dataProvider uses for its items.  If you then 
change the transient properties of that VO, the set data method of the 
itemRenderer will work out of the box; and you can then adjust the renderer.  
You're right in feeling dirty having an itemRenderer reference a model.  But 
reacting to changes in the data is fine. IMHO.

[flexcoders] Re: Updating renderer properties

[turbo_vb]

If it's a pure style, then yes that is a viable approach.  However, if it's 
something like changing text (characters, not styles), then you might want to 
use [Transient] properties in a VO and/or use states in the itemRenderer.

[flexcoders] Re: Updating renderer properties

[turbo_vb]

One thought, since you're taking about a style, is to assign a styleName to the 
itemRenderer and update the backgroundColor style of the StyleDeclaration when 
the user changes the color.  You may need to override the styleChanged() method 
the itemRenderer, to handle the update.

[flexcoders] Re: how to use stage in mxml

[turbo_vb]

The stage isn't available immediately.  That's why you get a null error.
With a little trickery:

http://www.adobe.com/2006/mxml";

creationComplete="onCreationComplete()"

resize="getStageDimensions()">

[flexcoders] Re: Creating XML Document from Data

[turbo_vb]

Why change from an ArrayCollection to xml; especially if it contains strongly 
typed objects?  A bit easier to work with for hierarchical components or charts 
perhaps?

[flexcoders] Re: event when page is shown in ViewStack?

[turbo_vb]

The "show" event will work except for the first time; in which case you'd want 
to listen for the "creationComplete" event.

[flexcoders] Re: Getting the Y value for a line at a given point

[turbo_vb]

Hi Ryan,

You can get the coordinates of the point by using coordinate geometry and 
trigonometry.  The key would be to determine the angle (or slope) of the line 
segment and the distance to the event point.  Or, if you wanted to make the 
segments square, use form="step":

Ok, an easy way would be to add paddingLeft to the titleStyleName, or try to

[flexcoders] Re: Adding a custom UI component as a panel titleIcon.

[turbo_vb]

In updateDispayList() position the box:

tempBox.move( unscaledWidth - tempBox.width - 10, ( unscaledHeight / 2 ) - ( 
tempBox.height / 2 ) );

This would put it on the right side of the header, minus 10 pixels.

That's exactly what you should do.  To get around the the titleBar add
the box to rawChildren.

[flexcoders] Re: addItem Trouble with TileList

[turbo_vb]

If you need to check dups for other reasons that would work fine.  but,
if you just need it for this particular use-case, this is simpler:

public function addButton():void

{


  if ( dataRight.getItemIndex( rightTiles.selectedItem ) != -1 )
Alert.show( "Already exists" );





  dataRight.addItem( rightTiles.selectedItem );

}

Because guys like Gordon are here, I'll also say that Instantiate is the 
correct word; instead of initialize. :)

[flexcoders] Re: addItem Trouble with TileList

[turbo_vb]

Man, I always forget at least one thing.   You also need to initialize
the second ArrayCollection().


[Bindable] public var dataRight:ArrayCollection= new ArrayCollection();




Might want to give the itemRenderer a background, so that the double
clicks will be triggered on the entire area.

I'm trying to simply add the item renderer with all it's data from
tilelist to tilelist.  I'm using two arraycollections to do the transfer
and the data is being populated through an xml file.  I know it's just
maybe 2 or 3 lines of code that I probably need, but can someone help
me, please?  Thanks
