RE: {Disarmed} [flexcoders] Just getting started, hitting walls...
Hello Flex Community,
I am a very experienced CF developer, and I want to get into Flex.
Based on your first impressions, how does the support from the Flex
community compare with than in the ColdFusion community?

If you're listening for MouseEvent.CLICK, you're not going to get it when the mouse pointer simply enters anything. You get it only when you click the mouse button!

I'm in the Events topic now ,which I'm still struggling to understand (Capture, bubble phases). The application is very simple having a display list as follows. MainSprite ChildSprite TextField The Child Sprite has a certain dimension width, height. It contains the Text Field, width also dimension set smaller than Child Sprite. I've added an EventListener to the Child Sprite, the Event type is CLICK. The event handler will change the backgroung of the Child Sprite. The problem is that the event is triggered only if the mouse pointer enters the TextFiled area, which is a non expected behaviour. The Event should be dispatched as soon as the mouse pointer enters the Child Sprite area. Can please someone explain brievely if this is the correct behaviour and what should I do to trigger the handler event as soon as the mouse pointer enters the Child Sprite are, not until it goes the the text field area.

RE: [flexcoders] Re: Treat a string as a reference to an object?
I'm not sure what obj1, obj2, etc. are in your example. But if they're instance variables in your class, then obj1.foo this.obj1.foo this.obj1[foo] this[obj1].foo this[obj1][foo] are all equivalent. So you can look up a property by name on an object by name as this[object_name][property_name] Keep in mind that when you write a class in MXML, the id's of MXML tags become instance variables of the class. For example, if you have mx:Button id=b label=OK/ then this[b][label] will be OK. - Gordon From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of tedgies Sent: Friday, May 25, 2007 9:35 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] Re: Treat a string as a reference to an object?

[flexcoders] More DataBinding problems
So I have a singleton object holding data that I've bound controls to. To make sure changes in the control affect the object's properties I've explictly bound the other way in the mxml. Problem is when I want to use the same page for Updating, one Binding is firing before the other and essentially reading the empty interface into my object, instead of reading the object's properties and putting them in to the controls. Is there a way to force one bind before the other? Hold off on one set of bindings? Maybe wait till the screen's controls are initialized and then set up my object? Help?

RE: [flexcoders] Re: DataGrid HeaderRenderer Recreates every click
When a header gets clicked a HEADER_RELEASE event fires. That's a good opportunity to save away the sort information somewhere. I once recommended to someone that they actually subclass ArrayCollection and override the sort property so it didn't actually sort the underlying data, but instead called to the server. In doing so, the DG would check the sort on the collection and update the arrows correctly. I don't know if they got that to work, but it should. Other than, simply storing the column index somewhere should be good enough.

The issue is when a user clicks a column header, all the column headers are re-created and now there is no way to know what just happened since any state of that click event is lost. So I guess I am forced to save it outside the headerRenderer. I suppose I can store the column index of what was clicked, then each column when it redraws itself can get that int (if it's not -1), look that value up in the 'columns' array and see if itself is it. If so, then display the appropriate up/down arrow. --- In flexcoders@yahoogroups.com mailto:flexcoders%40yahoogroups.com , Alex Harui [EMAIL PROTECTED] wrote: People do some really tricky things in customized DGs like having headers grow and shrink or other rows grow and shrink based on rollover states and selection and what not. Right now the DG aggressively redraws to make sure we don't make assumptions about what can change.

In other words, my headerRenderer mxml implementation, the creationComplete event gets called any time ANYTHING is clicked in the grid, including a row. This is a problem for many reasons, but the most significant one being that I cannot store the state if the column is ascending/descending based on the user's click. I could store this externally in the model but that is very bad b/c then I'd also have to store which column was clicked and then the other columns have to check if it is itself and remove the arrow if they have one.

Try calling validateNow after setting enabled to false. Animations can shut down validatiom. If you can disable and re-validate before the animations start, that would be best.

There are two ways, using a boolean flag in the application that

What you said the first time would work IF the boolean flag is in

the popup manager would have already created another popup on top of

.. in your app

Before installing hotfix 2 it was working fine, but after I see *Items* as an Object instead of Array so my code break. Note that the *Items* Array contains only 1 object, I couldn't test if with the array lenght greater than one I would see as an Array.

Hi,
There is no problem with what you have but... his question was,
how to i prevent a popup if the popup TileWindow is already Open..
That means, he is asking how does he only create ONE TitleWindow after a
user has clicked the button to create it the first time.
There are two ways, using a boolean flag in the application that
holds the
button or doing what I showed by checking if the instance is not
null in the
application.
What you said the first time would work IF the boolean flag is in
the actual
application. It wouldn't work if the flag was in the title window
because
the popup manager would have already created another popup on top of the
first popup.

Hi Mike,
The manager will have already created the instance and the
TitleWindow
would have to use removePopUp() which is not optimum.
I didn't understand what is the issue in using removePopup inside
Titlewindow ?
Let say if I write the following to handle window closure , is
there any
issue in this ?
mx:TitleWindow showCloseButton=true close={onClose(event)}
mx:Script
![CDATA[
public var isOpen : Boolean = true;
private function onClose(event : Event) : void

PopUpManager.removePopUp(this);
isOpen = false;

public function setOpen() : void

You need to take that call out of the mxml and create a click
handler for
the button.
.. in your app
private var popUpWindow:TitleWindow;
private function button_clickHandler(event:MouseEvent):void
{
if (!popUpWindow)
{
popUpWindow = TitleWindow(
PopUpManager.createPopUp(this,main,false));

Re: [flexcoders] Problem removing popup window
Having the same problem here.
Stepping through the code, I get to this function in
mx.managers.SystemChildrenList.
public function removeChild(child:DisplayObject):DisplayObject
{
var index:int = owner.mx_internal::rawChildren_getChildIndex(child);
if (owner[lowerBoundReference] = index
index owner[upperBoundReference])
{
owner.mx_internal::rawChildren_removeChild(child);
owner[upperBoundReference]--;
}
return child;
}
Where:
index = 2
owner[lowerBoundReference] = 1
owner[upperBoundReference] = 2
So the child is not being removed.
Any ideas?

Re: [flexcoders] Hyperlink in datagrid
As you say.. you are right when we use a small text like fail in pass. I was trying to be generic that is all. But still when you use a link button it will not replicate the style of the datagrid. It will look different in the DG. But thats my point of view. As a matter of fact I am using the link in the datagrid. In my case I am using domains and urls. And I tried using it with link button. But since my datagrid was not that big to occupy a bug URL I got scrolls and even some URl didnto appear in the DG. Thats why I shared that with you guys.

Re: [flexcoders] Deploying Flex app to web server
Its a common error... anybody can get it... I dont think there is nothing related to the webservice. Few things you need to check with are.. 1. Check is any component is being processed even before it has been created. Example if you use a viewstack, you can show only one tab at a time. But you might be trying to load a component at the other tab which is never created. Say if you have a chart in one tab and a tree in the other and by default the chart displays first. But when you try to load the app and you also try to load the data to the tree it might throw the error what you get. Because the tree component is not yet created. By default the components visible to the eye are first loaded. To overide this aspect just use creationPolicy = all in the viewstack. 2. The one or more of the objects used inside the file might be null and yu still try to use to access its functions. like when a array object is null and when you try to use the length function of the object you get this error. 3. To avoid the default error you can use a try catch in the functions and have your own error alerts. To trace the line where the bug exisits you can use a trial and error method. But it consumes lot of time. Or use some Alerts here and there to trace.

RE: [flexcoders] What functions do I need to override to return correct component size?
Hi Mike, that sounds pretty similar to what I'm trying to implement. Drag selecting via mouse and one or more component selection (either from drag select, or clicking with mouse). I've implemented drag selection by using a UIComponent and the following function - startSelection, updateSelection and stopSelection (called from a parent controls mouseDown, mouseMove and mouseUp, respectively). What do you have a selection queue for?? I figured I would have a list of selected objects, but not much more than that. With the popup overlay, do you use the popupManager? And I presume for client overlay you just add the selection as a child of the control? Thanks for your insight!

Hi, Actually I have a really complicated selection manager component. It works great. It does multi selection so there is client selection rectangles and then a popup selection rectangle that encompases all selected components in a canvas. basically you have the option of a popup overlay or client overlays. I use both. it gets complicated if you want more than just basic functionality. As far as moving, just add listeners to the component that is selected, MOVE, RESIZE and handle it from there. Mine even has a mouse selection rectangle and all that but, then I use a selectionQueue in the manager. complicated ;-) Peace, Mike On 5/31/07, Mark Ingram [EMAIL PROTECTED] wrote: So if you go via the manager approach, the manager adds the selection as a child to the component? e.g. textArea.addChild(selectionManager.newSelection) ?

Hi, Yeah, I have a manager that does exactly this. Basically my advice is, keep the UIComponents seperate from your selection. Use some sort of singleton manager that you register selections with. Then when a user or application geasture allows a selection, use the manager to create an instance of your selection, embed it into the UIComponent and either offset the graphix or create the overlay -10 pixels from the components x and y and adjust the width of the selection overlay by 10X2. This way you are only dealing with the overlay's size not the component's. Another simpler approach is if you have certain components that are selectable. just create the overlay in each in their createChildren(). Create an ISelectable interface interface; function get selected():Boolean function set selected(value):Boolean; Then when your components are selected they turn the visible to tru on the overlay and size it to the dimensions you need with the offset.

Hi, Yes it does. Here is the way it works, You need to figure out why you need a - offset because really, this does not fit into the framework. The only time, a negative offset is viable is an overlay(that is not measured with the component's children). Think 4th dimensionally here, why do you need the offset? The layout manager assumes every component is a rectangle inside it's x,y width and height bounds. This is where measure comes in. Your measured values must comply with the actual content you are measuring inside your UIComponent virtual rectangle. Any deviation from this will just result in layout bugs and unexpected behavior.

[flexcoders] Remote controlling multiple Flex2 apps - Push, sockets anything ?
I'm looking for a way to control several Flex2 apps, running on their own client. This is my scenario: We need to build a videowall using 6-8 30 monitors, where our monthly magazine is displayed spread by spread. This is to be able to see the flow of the magazine in real time (it changes by the hour almost, advertisers coming and going) So what I'd like to be able to do, is to control each of the monitors, that are attached to their own PC/Mac. I want to be able to control what pages are shown on which monitor. How can I remotecontrol the flex2 app ? I need to make them reload pages, zoom, etc. from a central control app - also Flex2. Can I broadcast an event to the other clients (propably not) Can I use some socket connection to control them ? Any pointers or ideas will be greatly appreciated. Thanks, Mark
[flexcoders] FileReference and dragdrop
Hi I am playing around with an apollo/rails app that allows you to upload/download files between the server and the apollo client. I am using FileReference to do the upload and download and this works like a charm. What I would like to do is to create 2 lists - local and server (like total commander/ftp client) and be able to drag and drop between the server and the client. I would need to use FileReference without the dialog boxes and I would need to get a list of files in a directory on the local machine. I have read many comments about attempts to use FileReference without dialog boxes and havent seen anyone who got this to work. Does anyone have any suggestions? Whether regarding the drag and drop instead of dialog boxes or ways to get a local file/folder list? Regards

Re: [flexcoders] What functions do I need to override to return correct component size?
Hi Mark, The selectionQueue is a queue that holds a list of all the selected UIComponents. I use this for my resize, snap, rotation and move managers. Basically, you add a component as a client of the selection manager, it then registers listeners to the client like mouseDown, mouseOver, add, remove, etc. When the component receives an event such as mouseDown, it activates the selectionManager's mouseDown handler. this way all of the interaction is delegated to the manager. The manager does the necessary function to the client and adds the client to it's queue. It also activates or deactivates the clients selection overlay while updating it's own popup overlay. The popup overlay is placed in the systemManager's popupChildren list. I don't use the popupmanager. I manage the popup overlay throught the selection manager. I have a lot of extra stuff in my manager because it works with all of the other managers I mentioned. This way you abstract a selection algorithm and you can easily use the manager for group resize, move and other function dealing with group selection.

[flexcoders] Module Mania
Im trying to create a modular application using SuperPanel. I have the Main application, which calls a funciton that creates a SuperPanel ( a floating Panel ) which loads a Module. Now in this Module, I load a Tab Navigator that loads up a bunch of buttons, which on click, runs a function that creates a SuperPanel, and loads a module in it. 2 Problems. With what I described, when the first Module loads up everything is fine, but when I have that try and laod a module, it loads the panel within its panel, and I want new windows to be loaded on the main app so it is not bound by the creating module. Second issue, is how to I make a loaded module expand to the width and height of a resizable parent object?
[flexcoders] Re: Flash Poll Application but with Flex Integration Charts
Hi Sher, Did you solve your problem? That pie chart looks quite nice to me. Did you create the pie chart component yourself? The reason I am asking is I'm doing a similar project right now and would appreciate your advice. It's my understanding that the Flex Component Kit allows you to import your Flash movie into Flex to use as a component in a Flex app. This might be overkill for your purposes as the resulting Flex app might end up over 200KB and will require Flash Player 9 to play.

Hello Darren, No the problem is still there.

[flexcoders] Re: Actionscript SAX Parser ?
--- In flexcoders@yahoogroups.com, Gordon Smith [EMAIL PROTECTED] wrote: I'd be interested to know what your use case is that requires a SAX parser. In my application, I had two list/search forms which: * query billing-related events (fairly static) * query/rank/prioritise tickets in a ordering/support system In both cases, there can be anywhere between 200 and 50,000 rows returned from a database for each query, sent to the Flex client via SOAP. (That number could grow to 100,000 in three years.) It's *not* useful to have paged views of that many results in the client application; it makes it much more difficult for the user to skim the records and have a good mental picture of what has occurred in the back-end systems. Also, the user wants to type/customise a query, and expects to get back *something* within 1 second, even if the full results take much longer to arrive. How large is your XML? Did you run into a memory or performance problem with AS3's E4X capabilities? AS3 on my laptop (Athlon64-2700, WinXP, Firefox 2, non-debug) takes 70 seconds to retrieve the full SOAP response (5 rows, 8 variable length string columns - about 14MB - over 1-3mbit broadband). I assume about 1 second of error in this measurement because I could only measure when the server stopped sending data. After the response has been fully sent, the Flex client takes 10-12 seconds (seems to depend on system memory utilisation) to parse, E4Xify, bind and update that data into a very simple DataGrid component. The performance of the DataGrid component is actually pretty damn good (even with 10,000+ rows)... no complaints there. I'm *not* complaining about the AS3 E4X parser's performance... it's remarkable that it does it that fast (my perl client using a c-based XML parser library only does it 3.5 times faster on average). I realise that my example is extreme, but in *many* use cases the data takes quite a bit longer to download than to parse... if the whole document must be parsed, an unacceptable amount of time elapses between sending the query, and getting something back to the user. The second important issue is memory usage. Very unscientific viewing of the task manager leads me to believe that the Flash plug-in allocates about 34MB while parsing the XML response. 34MB is not so bad when objectifying a document of that size... but it does have a large performance impact... it makes *much* more sense to parse the document with a constant 4-12kbyte buffered approach. - I'd skip this part if I were you - Years of service software development has led me to construct my service APIs so that they return data in a streaming fashion - whether the client supports it or not - because it provides much greater flexibility in how that data is used by different client applications. All databases in almost all server-side languages have APIs allowing the user to perform a query then iterate over the result set, only retrieving each row from the database as it is needed. It is well accepted that this results in much higher performance for non-trivial amounts of data. Web-service (say SOAP) libraries that allow streaming are relatively new, but have been available to Java developers for at least 5 years, and to Python developers for at least 3 years. (I use Perl... I actually had to modify SOAP::Lite to make streaming work). --- Basically, with large amounts of data if you retrieve the full response it takes too long to finish and allocates too much memory... both degrade the user experience. -David.
[flexcoders] Drag Drop functionality in Flex/AS3
I would like to do drag and drop on panels. To do this, I'm using a Canvas containing 3 panels like this: -| || | PANEL 1 | || - - || || | PANEL 2 | || || - - || || | PANEL 3 | || || || - The 3 panels are vertical align manually. Using panels on a Canvas, the panels move correctly. I would like that when we drag a panel, it can't be drop to another. Thus, we would be able to exchange panel's position without superimposing. Notice 1: The 3 panels can have a different height Notice 2: The top would be to be able add more than 3 panels Have you got an idea how to do this? Thanks for your help.

That means, he is asking how does he only create ONE TitleWindow

There are two ways, using a boolean flag in the application that
holds the

null in the

What you said the first time would work IF the boolean flag is in
the actual

the popup manager would have already created another popup on top

[flexcoders] itemRenderer null object error
I am so happy I was able to create an itemRenderer with an initialize
event that dynamically set the style for each item based on the source
data. This worked flawlessly for one HorizontalList ( List A) so I
tried to implement the same on a TileList (List B) on the same layout.
They have virtually the same dataProvider - List B items are
originally drag/dropped to List A.
These list are nearly identical in every way yet when the event fires
for the itemRenderer in List B it fails with null object error. It
seems that the data is not available when the event dispatches. I am
at a loss as to why it works for one list and not the other. The data
used by the event is not null when it renders since all the items
(data) are accounted for.

[flexcoders] Re: [SOLVED] itemRenderer null object error
Maybe I've a little naive but I like making nearly everything in
actionscript 3, especially itemRenderers. Then, you can handle all the
positioning and styles in the updateDisplayList function if you want.
This generally follows the Adobe approach to it as well. I say start
with looking over Adobe code for itemRenderers, and see where you need
to add your code to make it do what you want.
In the end you avoid listening for events, and not knowing what event
is going to fire in what occasion.

[flexcoders] AddChild problem
I am not sure this as much a problem as I am probably doing something
wrong. I am adding child components at runtime to a vbox. These new
components can be dragged to a new position. This all works. The
'problem' is that when anytime a new child is added, all the child
components move the top left corner of the container they are added
to.
Code Below:
public function creatObj(what:String):void{
var obj:UIComponent;
switch(what){
case rssFirstName:
obj = new textComponent;
//container_vb.addChild(obj);
break;
case rssLastName:
obj = new textComponent;
//container_vb.addChild(obj);
break;
case rssEmail:
break;
case text:
obj = new textComponent;
//container_vb.addChild(obj);
break;
case textArea:
obj = new textAreaComponent;
//container_vb.addChild(obj);
break;
case checkBox:
obj = new checkboxComponent;
//container_vb.addChild(obj);
break;
default:
break;
}
container_vb.addChild(obj);
}
I really need to figure out why this is happening, so any guidance is
appreciated.
Thanks

Alex meant to say If a method is overridden, you can NOT skip around

The way the framework codes around the lack of super.super is to use the
following pattern:
class A
{
function f()
{
doSomething();
}
}
class B extends A
{
// This will hide A's f()
override function f()
{
doSomethingElse();
}
// But this makes A's f() available as B's $f
final function $f()
{
super.f();
}
}
class C extends B
{
override function f()
{
$f(); // call A's f() -- which is effectively super.super.f()
}
}
Using $ in the name is just a convention which indicates that you're
getting the original, un-overridden function. We also make it final to
guarantee that it remains un-overridden.

Yes, exactly how you wrote it. However in order to have the top level
function actually run before adding methods etc... with level 2 you need to
call super.myMethod(); from B or not override it at all in B to be able to
access it's functionality! from C. In other words, if you override a
function and then try to override it again in a class extending the one with
the original override and don't call the super version in the intermediate
class then you end up with an empty function at the end.

[flexcoders] Data binding will not be able to detect changes when using--I know I know
I'm sick of seeing Data binding will not be able to detect changes when using square bracket operator. For Array, please use ArrayCollection.getItemAt() when using an arrayObj[arrayPropertyOrIndex] inside of an MXML property. I know that it won't be propagated down if the array changes, but in a lot of cases, I don't need it to propagate down, and I don't want to take the performance hit of using a more expensive object (ArrayCollection) and in addition to that, having extra event subscriptions to something that will never change. So why does the compiler have warnings for it? It makes me feel like I'm doing something wrong when I see a bunch of warnings. :( I wish I could have a [Not-bindable] tag or something just to shut that particular warning up. (rant over) Suggestions? Thanks guys, love the group. James Wilson Atlanta-area Flex Programmer [EMAIL PROTECTED]

What you said the first time would work IF the boolean flag is in

[flexcoders] Really complex buttons (aka what WPF got right)
Hi, I'm still learning Flex and during the last few hours, I've been struggling with some button-related problems. I am trying to create a button which contains not only label and icon but any arbitrary contents. If Flex was WPF, you could do something like mx:Button mx:VBox mx:Label ... / mx:Image ... / custom:Component ... / /mx:VBox /mx:Button This approach really saves a lot of time and hassle but unfortunately is not implemented in Flex (this would be great for future versions). What I did in Flex was that I created a custom component based on Canvas (say MyButton) and designed it however I wanted. I've set the buttonMode property to true so I now have the nice hand cursor. Click event is automatically there... So far so good. But the ultimate goal is to have something like TabNavigator, except that the tabs are pretty complicated MyButtons. No again, because the TabBar is based on buttons, you can only set label and icon. I don't think I can help myself creating a new class based on TabBar because the Button limitation would be still there. As far as I can see it, to have a custom button is fairly common scenario and I can't believe that Flex makes it so hard for me as a developer. There must be some way that I have simply missed. Could anyone more experienced please advise me, or generally comment on Flex composability of more advanced controls? Thanks, Borek

Maybe I've a little naive but I like making nearly everything in

This generally follows the Adobe approach to it as well. I say start
with looking over Adobe code for itemRenderers, and see where you need
to add your code to make it do what you want.
In the end you avoid listening for events, and not knowing what event

RE: [flexcoders] Really complex buttons (aka what WPF got right)
Hi Borek. I can give you the short answer, which is that composition is an important goal of the flex framework. But we have two design goals which WPF doesn't have - specifically - keeping the framework something that will perform well on the 98% of the machines on the internet that currently have flash deployed (WPF has much heavier client requirements). - keeping MXML something that a developer and/or designer can look at, easily read and comprehend, and code by hand as appropriate (most XAML files that I see tend to be fairly hard to read to the typical developer). Both of these have forced us to walk a delicate line between power and simplicity in our component framework, and composability is one of those areas where we have been forced to make hard tradeoffs (and continue to debate them on a daily basis). Having said that, the move to Flash Player 9, AS3, and the new AVM+ has given us additional power (usable on the broad majority of the internet...over 85% penetration at this point, I believe) that we've only just begun to take advantage of in the framework. Expect to see us weaving composition deeper and deeper into the framework as it evolves. I should also mention that there's technically nothing stopping you from making composable controls like flexible buttons today. Personally, I believe it's worth every flex developers time to learn a little bit of component development; while there may be an initial up front learning investment, Once you have the knowledge, banging out a couple of custom built or reusable components doesn't take a lot of work. But building that kind of flexibility into every push button in every flex application, without paying a non-trivial cost in performance and complexity, is something that takes time and consideration.

I am not sure this as much a problem as I am probably doing something

'problem' is that when anytime a new child is added, all the child
components move the top left corner of the container they are added
to.
Code Below:
public function creatObj(what:String):void{
var obj:UIComponent;
switch(what){
case rssFirstName:
obj = new textComponent;
//container_vb.addChild(obj);
break;
case rssLastName:
obj = new textComponent;

case checkBox:
obj = new checkboxComponent;

[flexcoders] Re: An odd problem with the 'width' and 'height' of Sprite
Troy,
One thing to note in my trial and error, changing the height and width
then resetting the scales properly displays the content...until you
want to do a scaling operation. The very next scaling (i.e. via
scaleX = blah) operation uses the height and width computed from
'resetting' the scale. In my case all I wanted to do is perform
scaling operations. Attempting to restore the original image (via
scaleX = scaleY = 1.0 ) just didn't work after several scaling operations.
The only consistent mechanism I've discovered to date is to explicitly
create a new Matrix object and set it on the transform. Unfortunately
this seems to by-pass all of the properties; so you don't get an
updated height width.

Hi Cho,

This was mentioned recently so you could probably find some details

I'll repeat
what I learned as best as possible:
When you set the width and height of a sprite, Flash attempts to
scale the

height but
it will also adjust the scaleX and scaleY properties such that *if* your
sprite had content it would be scaled up to the new size (kinda what you
would expect if you resized a movie clip).
Of course, the big problem is that the documentation for
width/height (or

that the
behavior has simply been deduced through trial and error (Gordon or
other
Adobe folks, I'd love to see some official confirmation on what's

What is happening in your case is the width and height of your new
Sprite is
0 because it doesn't contain any vector art, etc. So, you set the
width and
height manually and the Sprite attempts to adjust scaleX and scaleY to
compensate. Since the width and height are at zero, the scales
become NaN
(division by zero), and thus are set to zero. Now, future drawing/sizing
gets squished by the fact that scale is set to zero.
To fix it, you can set your width and height *then* reset scaleX and
scaleY
back to 1.0. That should do it.

As the title, I've met an odd problem with using Sprite class.
Because I'm a novice of Flex, my problem may be so trivial.
But Your helps would make me happy.
The simple version of my code is below.
public class CustomSprite extends Sprite
{
public function TCellView(w:Number, h:Number) {
this.width = w;
this.height = h;
draw();
}
private function draw():void {
this.graphics.clear();
this.graphics.lineStyle(2, 0x00, 0.7);
this.graphics.drawRect(0, 0, this.width, this.height);
}
}
The problem is that the assignments to width and height in the
constructor of mine have no effect.
So in draw(), the rectangle to be drawn has size of zero. The
width and
height are public properties of Sprite and are not read-only.
Then why does the code like 'this.width = w' have no effect? (In debug
mode of Flex Builder, the Variables view told me the values of
width/height of the Sprite object have not changed by the codes.)
After some investigation, I knew that the drawing on the graphics of
Sprite causes update of width/height.
That behavior is reasonable, I think. However, I wonder why a
direct-assignment to width or height is banned, and how.
Is there any mistake in my code? Or Do I misunderstand something?
Please, tell me what's going on behind the scene about Sprite.
Any replies of you would be grateful.
Thank you.

Re: [flexcoders] Data binding will not be able to detect changes when using--I know I know
I would expect you to only get that warning if you're using binding with the
MXML property... if you're not using binding, then it shouldn't care (it'll
just initialize the value at the time of instantiation). Does your MXML look
like this:
mx:Label text={arrayObj[0]} /
I'm guessing you're doing that because you want arrayObj[0] to be
evaluated, as opposed to this:
mx:Label text=arrayObj[0] /
Where you'd actually get just the literal text.
The problem is that the curly braces *mean* use data-binding. What you're
doing (if you're doing something similar to the above) is taking advantage
of the fact that data-binding *also* means evaluate the expression to set
the value (as a step in the data-binding process).
I guess the correct way to get the results you're looking for is to
initialize the values in an event handler (like creationComplete).
Of course, you shouldn't be afraid of ArrayCollection... I've not tested it
to be sure, but I can't imagine you'd have enough UI elements bound to
enough ArrayCollection elements to make any kind of performance difference
that would out-pace the performance cost of the UI elements by themselves.
Event dispatch is all done natively in the Player... it seems to be
reasonably chipper.

RE: [flexcoders] Re: Data binding will not be able to detect changes when using--I know I know
Actually, whether you create an ArrayCollection or not, we will so it is
the same memory either way. List classes and ComboBox only actually
work with collections. If you hand us a bare array, we wrap it, if you
hand us an ArrayCollection, we take it as is.
IMHO, I recommend:
mx:ComboBox
initialize=LICST.dataProvider=Application.application.StateListArray
prompt= id=LICST/
CreationComplete is late and can cause an extra rendering pass.
initialize is earlier. Also you avoid the overhead of the binding
setup for something that may never change.
Assigning values of other objects as the value of MXML attributes is a
long-standing annoyance of XML in general. Wish there was a better way,
but if you want to optimize startup, don't use binding unless you plan
to change it later.

Re: [flexcoders] Re: An odd problem with the 'width' and 'height' of Sprite
Yeah, I agree, the magic in the scaleX/Y and width/height properties is
frustrating... it would be nice if someone (Adobe, hint, hint, nudge, nudge)
would provide a detailed explanation of what's happening under the hood and
what the expected functionality should be.
The only guaranteed thing I can find is that width/height are *always*
correct (in the parent's coordinate space) if I treat them as read-only and
using drawing to the sprite as a way to adjust its size. In other words, a
sprite doesn't appear to work as a general purpose container that I can size
to anything.
Personally, I think width and height should be like x and y, independent of
scale. My impression is that they wanted people to be able to load something
into a sprite and make it twice as big by saying mySprite.width *= 2. That
seems to conflict (or at least make non-trivial) the relationship between
scale and size, particularly in the edge case of an empty sprite (where size
is 0).
In the end, I think the API is *broken* design wise and is full of hacks to
make it work in the way people used it... but I may be wrong, hence my
desire for a definitive explanation from Adobe.

I can give you the short answer, which is that composition is an important goal of the flex framework. But we have two design goals which WPF doesn't have – specifically - keeping the framework something that will perform well on the 98% of the machines on the internet that currently have flash deployed (WPF has much heavier client requirements). - keeping MXML something that a developer and/or designer can look at, easily read and comprehend, and code by hand as appropriate (most XAML files that I see tend to be fairly hard to read to the typical developer). Both of these have forced us to walk a delicate line between power and simplicity in our component framework, and composability is one of those areas where we have been forced to make hard tradeoffs (and continue to debate them on a daily basis). Having said that, the move to Flash Player 9, AS3, and the new AVM+ has given us additional power (usable on the broad majority of the internet…over 85% penetration at this point, I believe) that we've only just begun to take advantage of in the framework. Expect to see us weaving composition deeper and deeper into the framework as it evolves.

[flexcoders] Bug when resizing IE7 vertically (only), movie doesn't resize to fit
I have a Flex 2.01 Application that has a Panel (and then a bunch of sub-components). It is set to height and width of 100% in the container aspx file. When I run it in IE7, if I only resize the browser vertically, the SWF does not resize to fit. If I make the window taller, there will be blank white space at the bottom as the panel stays its same size. If I make the window shorter, then a vertical scroll bar appears. However, if I resize horizontally, then the movie stretches or shrinks moviong all of its components as I expect, always staying the right size to fill the browser window. If I have resized the window vertically, creating a blank space or a scroll bar, as soon as I resize a pixel either way horizontally, the movie immediately resizes itself to fit in all directions. Is this some sort of display bug in IE? I have tried changing the layout of the Application, the height and width, and the alignment of the SWF object in the hosting page javascript. I copied the javascript holding the SWF directly from the auto-generated HTML file - except the host page is an ASPX file. Does anyone know if there is something related to it being an ASPX page that doesn't throw an event when changing its size vertically? Thanks, Pete

[flexcoders] TextField autosize a bunch of ****
Okay, maybe my brain took the weekend off early, but I just can't get TextFields to cooperate... (BTW, this is an AS3 Project, so no Label or Text or other UIComponent suggestions, please!) I create a TextField: var text:TextField = new TextField(); That I want formatted like so: text.defaultTextFormat = new TextFormat(Courier, 18); And I want the TextField to automatically size itself to its text: text.autoSize = TextFieldAutoSize.CENTER; And then, at various points in my program, I change the text: text.text = Some text; What I expect is that the autoSize will adjust the size of my component so that it *completely* fits my text I set to it without me having to do anything (at least that's my understanding of auto). So, I assume I could throw my TextField to a certain point on the screen: // centered near the top edge of this DisplayObjectContainer text.x = this.width / 2; text.y = 10; And whenever I updated the text it would remained center along the top edge of the screen. I assumed it would do this internally by having the text go to the left of the TextField's position (using text.x and text.y as a registration point, so to speak). What I discovered, frustratingly, is that it appears that what it actually does is simply *change* the x/y values I loving calculated (when autoSize == CENTER) and modify the width/height (as necessary). Okay, well I grappled with that by doing this in my update code: text.text = ; text.x = this.width / 2; text.y = 10; text.text = newTextValue; This seemed to work... or so it seemed... now, the autoSize seems to only happen the first time I update the text! So, it sizes just right to the first value I stick in there, but the second value (which is longer) gets truncated! Do I have to reset autoSize each time? What gives? Is there something I could be doing in my code (save clearing autoSize) that would result in a TextField truncating its contents? I would assume that if autoSize is set to anything other than NONE I would *never* have truncated text, but obviously I'm wrong! Any ideas? Troy.
[flexcoders] Re: textAlign not working for TabBar
Yes, Thank You! I was trying to set the textAlign property
on the TabBar directly. You've reminded me that the TabBar
is a collection of tabs. The CSS approach apparently is
needed to set the style of the children tabs through the
tabStyleName setting.
Thanks, this was a great help!!
Below I've included another version that also works.

mx:Style
.leftTextTab {
textAlign:left;
}
/mx:Style

Hope that helps.

Great suggestion. I had not thought of this.
Unfortunately, though, this didn't work. I applied
in a couple of different ways and still no luck.
But, again, thanks for the suggestion! It was
worth a try.

I know you can set that via styling:
mx:Style
Tab {
textAlign:left;
}

I'm not to get textAlign=left working on the TabBar
control. I've searched the archives and find no
references to this issue.
Is my code flawed in some way that I'm just not catching?
mx:TabBar direction=vertical
dataProvider={vacCAppList}
labelField=app width=300 textAlign=left
itemClick=fSelectApp(event)/
Has anyone else had this problem? If so, have you found
a work-around.
[flexcoders] databing to model object with arraycollection
Hi,
I have a custom object (defined in .as) with this property:
[Bindable]
public class ExperimentModel implements IXmlSerializable
{
...
//element type is subclass of Therapy
public var therapies:ArrayCollection = new ArrayCollection();
public function addTherapy(element:Therapy):void {
therapies.addItem(element);
therapies.dispatchEvent(new CollectionEvent(
CollectionEvent.COLLECTION_CHANGE ) );
}
I then have another class which sometimes works with databinding,
sometimes not.
mx:Panel xmlns:mx=http://www.adobe.com/2006/mxml;
xmlns:com=therapyComponents.*
layout=vertical width=400 height=300
mx:Script
![CDATA[
import mx.events.CollectionEvent;
import com.entelos.realab.model.Therapy;
import com.entelos.realab.vo.PatientVO;
import mx.collections.ArrayCollection;
import com.entelos.realab.model.ExperimentModel;
[Bindable]
public var model:ExperimentModel;
private function getlen(a:ArrayCollection):Number {
return a.length;
}
private function negate( value:Number ):Number
{
return -value;
}
]]
/mx:Script
mx:Text width=100% id=t1 text={model.therapies.length}/ !--
this works --
mx:Text width=100% id=t2 text={getlen(model.therapies)}/
!-- this does not --
mx:Text width=100% id=t3
text={negate(model.therapies.length)}/ !-- this works --
com:boundText val={model.therapies}/ !-- this does not --
mx:DataGrid dataProvider={model.therapies}/ !-- this works --
/mx:Panel
Obviously I can use the .length property for my bound therapies
ArrayCollection but not my therapies as-is. Why is this?
Thanks
