Re: [flexcoders] Cross-domain data flow
That's right. The browser will contact YouTube and Flickr directly to load content from those websites. Only the SWF will be loaded from your site.

Re: [flexcoders] Closures in ActionScript 3?
On Fri, Jun 5, 2009 at 7:58 PM, Keith Hughittkeith.hugh...@gmail.com wrote:
Could someone please explain to me how closures work in ActionScript? I am
attempting to create a set of Flex Form fields, and assign an event-handler
to each of them, however, it seems that after creation, all of the fields
have the same event handler.
[...]
Let's take a simple example.
var funcs:Array = [];
for (var i:int = 0; i 5; i++) {
funcs.push(function ():void {
trace(i);
});
}
for each (var f:Function in funcs) {
f();
}
First we push functions into an array. Then we iterate over the array
to call each function. What is the output?
5
5
5
5
5
The value of the variable i is 5. That's what gets printed when each
of the functions is called. It doesn't matter what the value was at
the time you set the function up. Ultimately when they are called, the
value of i is 5.
Now let's see how we can solve that. We want the functions to remember
state. Essentially we want a functor.
http://en.wikipedia.org/wiki/Function_object
Since Function is a dynamic class in ActionScript, you can add state
to a Function object without having to extend it.
Here now we modify the above example.
var funcs:Array = [];
for (var i:int = 0; i 5; i++) {
var f0:Function = function ():void {
trace(arguments.callee.index);
};
f0[index] = i;
funcs.push(f0);
}
for each (var f:Function in funcs) {
f();
}
f0 is a Function object that stores the index in an index property.
Later on when the function is called, we pull the value out of the
Function object for processing.
Here's the output:
0
1
2
3
4
If you're a purist, you can also create a class to do this.
class Functor {
private var func:Function;
private var state:Object;
public function Functor(func:Function, state:Object) {
this.func = func;
this.state = state;
}
public function call(... args):* {
return func.apply(state, args);
}
}
And use it like this:
var funcs:Array = [];
for (var i:int = 0; i 5; i++) {
var functor:Functor = new Functor(function ():void {
trace(this.index);
}, {index: i});
funcs.push(functor.call);
}
for each (var f:Function in funcs) {
f();
}
Output:
0

I was thinking that I need to set the show event of the tab to run a function that would launch the component but I don't the syntax for doing this. Is this component inside the TabNavigator? If yes, you have to set the TabNavigator's creationPolicy property to auto (default) and the component will be initialized only when the tab is clicked. If the component is outside the TabNavigator, then you can just add the component in the change event of the TabNavigator.

Do you need to use setActualSize on the label before you measure it?
No.
setActualSize() should be called in updateDisplayList(). That is
called after the measurement phase. The Label object will measure
itself based on the text assigned to it, so it doesn't care what size
you have set on it (for the purpose of measurement).
The Label object's getExplicitOrMeasuredWidth() and
getExplicitOrMeasuredHeight() methods will return the values computed
in its measure() implementation.

Re: [flexcoders] About how to implement UIComponent
2009/6/3 j2me_soul j2me_s...@163.com:
Why the label can't be displaied on the srceen?
public class rectElement extends UIComponent
{
private var lal:Label;
public function rectElement()
{
super();
}
You don't have to write a constructor if all you're going to do it
call the superclass constructor. Just so you know. You can still do it
if you consider it a good practice.
override protected function createChildren():void{
if( lal == null ){
lal = new Label;
lal.text = Label;
addChild(lal);
this.explicitWidth = lal.width;
this.explicitHeight = lal.height;
}
}
Normally a component should not set its own
explicitWidth/explicitHeight. These properties are to be set by the
Flex framework. A component should only calculate its measuredWidth
and measuredHeight, based on its contents. The right place to do that
is the measure() implementation.
override protected function measure():void{
this.explicitMinWidth = this.explicitMinHeight = 50;
}
}
Here you should set the meauredWidth, measuredHeight, and optionally
measuredMinWidth and measuredMinHeight (they can be set to the same as
measuredWidth and measuredHeight respectively).
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml; layout=absolute
mlns:local=*
local:rectElement
/* there is nothing on the screen. Where is the Label ? */
/local:rectElement
/mx:Application
Okay, you haven't implemented updateDisplayList(). That's where you
have do the layout. For example, in the following way:
function updateDisplayList(unscaledWidth:Number,
unscaledHeight:Number):void
{
super.updateDisplayList(unscaledWidth, unscaledHeight);
lal.setActualSize(unscaledWidth, unscaledHeight);
}
Basically your component object is first measured by the framework,
and then it is assigned a size. You have to lay out the contents of
the component based on the allocated size (unscaledWidth and
unscaledHeight).
It is also a good idea to always call the superclass's
createChildren() method at the end of your implementation.

ActionScript isn't multiothreaded. How can it load the next and play the current at the same time. Or did I not follow whatyou said correctly? You can call load() on one instance (or many instances) while the first one is playing. ActionScript is a programming language, and it has no native support for threads (it has no native support for events either). The Flash Player is the runtime. It has support for events, obviously, through the events API. The player is able to perform a number of asynchronous tasks in the background while the application continues to function normally. Typically for such tasks you'll get progress and complete events. You don't have to do any multi-threading for such tasks yourself: just start the task (by calling the load() method on VideoDisplay for instance) and wait for the events. Internally the player may be using multiple threads or just a single thread for these background tasks. It doesn't matter either way. If it uses a single thread, it'll just loop through these tasks in what can be called the event loop and perform them little by little on each iteration, at the same time processing user events as well. So you continue to get your mouse and keyboard events while the data is still downloading. Manish

That's not possible. Very annoying at times. The best you can do is to
set up an inline event handler:
component.loadData();
component.addEventListener(complete, function (e:*):void {

I try to avoid that though in all but the rarest cases. It makes the code messy.

Until recently, I did not know that you could reset the combobox back to the
prompt value by ctrl-clicking the value in the combobox dropdown. However,
as most people don't know that this is a possiblity with the combobox, I'm
trying to mimic this functionality by setting the selectedIndex to -1 if a
person clicks (without the ctrl key) the same value that is already selected.
I have yet to find the selectedIndexChanged property change to anything
other than false when the change event fires, so I'm unable to use that
(same for selectedItemChanged). I tried setting the item under the mouse
when itemRollOver fires to a property, then set it to null when
itemRollOut fires. Then when the person clicks, I said if the selectedItem
== the value underneath the mouse during itemRollOver, set the selectedIndex
= -1, however, the itemRollOut seems to fire before the click event is fired.
I've also yet to find where the code is for the ctrl-left click, or what
causes that event to fire.
The code is in ListBase.as: the selectItem function (called from
mouseDownHandler).
// allow unselecting via ctrl-click
if (ctrlKey selectedData[uid])
{
selectionChange = true;
clearSelected(transition);
}
Here's the solution.
1. Make a custom class, MyList.
public class MyList extends List
{
override protected function selectItem(item:IListItemRenderer,
shiftKey:Boolean, ctrlKey:Boolean,
transition:Boolean = true):Boolean
{
var index:int = itemRendererToIndex(item);
if (index == selectedIndex)
ctrlKey = true;
return super.selectItem(item, shiftKey, ctrlKey, transition);
}
}
2. Use this class as the dropdown in the ComboBox.
mx:ComboBox id=cb prompt=-- select -- dataProvider={['1', '2', '3']}
dropdownFactory={new ClassFactory(MyList)} /
Tada!

You can certainly have a scrollbar in a JavaScript-based data grid. What's more, the scrollbar actually matches in behavior with the one you use to scroll the page -- it's the same component. So that provides a more consistent experience. Some of the reasons I know that people avoid using Flash: 1. It tends to eat focus. (i.e. you can never tab out of a Flash object) 2. It doesn't obey the user's preferences with respect to font size and color 3. It's too large -- a Flex application just for a DataGrid would be 200+ KB 4. Some users don't have Flash Player, for whatever reasons 5. They don't have Flash/Flex development skills on the team Of course, there will be cases where it's desirable to use a Flex application embedded in the web page just to show a bunch of tabular data.

Re: [flexcoders] Question from a C developper
You should check out the int, uint, and Number types. The sizes are
predefined in ActionScript 3 and not system dependent (e.g. int is
always 32-bit signed).
Operator overloading is not available. You can create an 'equals'
method and use it like so:
if (obj1.equals(obj2))
...
You can create a simple class for a structure:
public class Contact {
public var name:String;
public var address:String;
public var phone:String;
}
And afterward you can use it like so:
var contact:Contact = new Contact();
contact.name = Joe;
contact.address = Los Angeles;
addToAddressBook(contact); /* function call */
ActionScript 3 is a pass-by-value language. Everything is passed by
value. When you pass an object reference to a function, the reference
is passed by value -- i.e. the function receives its own copy of the
reference.
If you're thinking of C++ references, this is not it. Think pointers instead.
Just to be clear:
function foo(ref:Object) {
ref.prop1 = new value;
}
var obj:Object = new Object();
obj.prop1 = old value;
foo(obj); // modified
trace(obj.prop1); // prints new value
Lastly, you can convert an int to a Number by simply assigning it.
var i:int = 10;
var n:Number = i;
If you're coming straight from a C/C++ background, there's a lot
you'll need to unlearn before you start to get a hang of ActionScript
3. But it's basically in the same family of languages, so you should
have no trouble.

Re: [flexcoders] Re: How to create universal event handler?

I think you are right. Since Event is represented by object, I thought
you could create event handlers in polymorphic manner, just like when
handling errors, when you write catch(e:MyErrorClass). Such catch
would also handle MyChildErrorClass error. It seems that this does not
work with events….
Well, you can use the same event type but with a different class. So
let's say your base event class is MyEvent. The event type is
myEvent. You listen to the event like so:
someObj.addEventListener(MyEvent.MY_EVENT, myEventHandler);
Your myEventHandler looks like this:
function myEventHandler(event:MyEvent):void
{
...
}
Now, so long as the type of the event object is MyEvent, your
myEventHandler should be able to execute without any problems. So the
author of someObj could write their own event class, say
SomeOtherEvent, like so:
public class SomeOtherEvent extends MyEvent {
public function SomeOtherEvent(...) {
super(...);
// custom properties, etc.
}
// custom properties
}
And they could dispatch the event:
someObj.dispatchEvent(new SomeOtherEvent(MyEvent.MY_EVENT, ...));
And your handler, myEventHandler, will be able to handle it perfectly
well. Isn't that what you're looking for?

Re: [flexcoders] When to use the include directive?

I've recently been working on poorly designed project where at the top of every module there is an include Header.as statement that has 30 include statements within it. To give a datagrid additional functionality, you give it an id=myDataGrid, and the include statement takes care of the rest. It's really bad. I just don't see a good use for the include statement anymore. In my opinion, it just promotes bad programming practices. I mean, can't everything be taken care of using OOP methodologies? The include statement is basically for static includes (compile time). I agree that using include in AS3 is like using C-style macros in C++ (instead of inline functions, class inheritance, and such). But sometimes that's just what you need. The Flex framework, for instance, uses include statements to include common style metadata into various components. Manish

So bubbling up to the app is critical. Since your component has nothing to do with UI, strictly speaking, making it a UI component (extending DisplayObject) seems like the wrong thing to do. Event bubbling is typically for UI events; your event is not a UI event, it's just that you need it to be broadcast application-wide. So I would consider making the event dispatcher object available application-wide, by making it a singleton, for instance, or by making it a property of the main application. It seems you're already doing something to that effect -- dispatching off the main application object. Manish

By Application I assume the Flex application (instance of

chain (parent.parent.parent) until you come across an Application
instance, or null.
inApplication = false;
p = this.parent;
while (p != null) {
if (p is Application) {
inApplication = true;
break;
}
p = p.parent;
}
Your loop will never run, however, since parent will always be null in
the constructor.
Note that checking for Application is different from checking for
stage. The Application may not have been added to the stage when
you're doing this check (even if not in the constructor). So if you
want to check if you're on the stage yet, just check for the stage
property.
onStage = (stage != null);

When you listen for an event on one of your ancestors, you usually want to use a weak reference (the last parameter to addEventListener).

Drag and drop Item 5 from the root to the Item 4.
Drag and drop Item 5 from the Item 4 to the root.
Expected result: Item 5 is deleted from the Item 4 and appears on the root

Actual result: Item 5 actually appears on the root in the drop position, but
it is not removed from the Item 4, so there are 2 same elements in the
hierarchy intead of one.
That's a good catch. You're right, it's because of parentMap not
getting updated on the first drag-drop. You'll see that the
HierarchicalCollectionView:collecitonChangeHandler has a call to
updateLength when the event kind is update, but it has been
commented. I suspect that may be the reason for this bug. Anyhow, for
now, here's a workaround:
Tree ... dragDrop=callLater(doWorkaround) ... /
function doWorkaround() {
var e = new CollectionEvent(collectionChange);
e.kind = update;
myXMLListCollection.dispatchEvent(e);

An RSL is basically a SWF that contains a bunch of classes. You can load the SWF when you need one of the classes. So a component that is shared between multiple modules could be part of an RSL.

Custom cursors are really graphics you display in place of the system cursor (which is hidden) at the current mouse position. There are a number of problems with this: you don't know when the system cursor has changed from an arrow to an I-beam, for instance, and it's often hard to keep up with the current mouse position, so sometimes the custom cursor might lag.

Perhaps its because it is an itemEditor, but just tried it and value in the
editorDataField saves the label string to the Grid, not the 'data' element.
Well, the value property is a little strange indeed. Not to mention
it's also deprecated. Here's what I suggest:
/* in your item editor */
public function get myCustomProperty():Object
{
var item:Object = selectedItem;
if (item == null)
return null;
return item.data;
}
DataGridColumn editorDataField=myCustomProperty ... /

Re: [flexcoders] hideing a tab in a TabNavigator

I would have that TabBar drive a Viewstack. That's another option, but let's not forget that a TabNavigator is more than just a TabBar + ViewStack. There's the focus management/handling which you get for free. Manish
Re: [flexcoders] Creating Asynchronous Classes
On Sat, Jan 3, 2009 at 3:33 AM, nathanpdaniel ndan...@bsi-scs.com wrote: Is there a primer on creating asynchronous classes? I've been building an app that runs a CRC32 check on each file (which requires looking at every byte of every file). It doesn't cause issues when the files are small text files, but when they're 40mb video files, the app hangs till complete. I want the app to be able to update other things while waiting on the CRC32 functionality completes. Actually, all I need is some visual progress indicator (some way to update the display). I once peeked into the source code of this library and thought it looked promising: http://blog.generalrelativity.org/?p=29 You should be able to split your CRC32 computation into chunks quite easily, either with this library, or with something more basic using just a simple Timer.

Re: [flexcoders] Using Flash Symbols in Flex.

I have read the following blog: http://www.gskinner.com/blog/archives/2007/03/using_flash_sym.html I can get the first frame of the Movie Clip to display in the Flex test application but there is no animation. From what I've read on other sites it seems that Flex strips out the time line (correct me if i'm wrong). You should be able to load the animation either by embedding or loading dynamically (both the methods you're trying). I suspect it's something to do with the loaded SWF itself. What happens if you call gotoAndPlay() on the MovieClip object (mc)? Manish
Re: [flexcoders] ModuleLoader with full url

Re: [flexcoders] ToggleButtonBar with one or more ComboBoxes instead of buttons: How to build it?
On Fri, Jan 2, 2009 at 11:06 PM, Alan Shaw noden...@gmail.com wrote: The dataProvider would be like a Tree's, so for example an array where some of the elements are leaves (- buttons in the bar) and some are arrays (- dropdown lists in the bar) (no deeper arrays, and no folder names). I want the user to be able to choose a single leaf item from the set, either by clicking one of the buttons or by choosing an item in one of the dropdown lists. All I can say is that you'll have to extend the NavBar class and implement something like a ToggleButtonBar that uses ComboBox as a nav item in a sophisticated way. It's doable. Essentially what you're looking for is a cross between a MenuBar and a ToggleButtonBar, so I would draw inspiration from those two components. Manish -- http://manishjethani.com/
