RE: [flexcoders] Watching a class full of bindable properties
There are a few glitches with what you propose:
First, you cannot create a watcher that monitors all of your properties
at once. The binding chain contains a hierachy list of parents and
children. The chain is there so that any change on the parents or
children will trigger the binding. Your proposed approach will
definitely not work.
Second, the only way to detect a change on a property is to create a
setter/getter pair. And I personally don't think that creating
setters/getters makes a class hard to read but this is just my own
opinion.
Finally, if you want to make a read-only property bindable, the class
has to support the IEventDispatcher interface and your class doesn't
seem to. Make sure it derives from EventDispatcher or that it at least
implements the IEventDispatcher interface.
If you're still convinced that using setter/getter is ugly, you may want
to look into the Proxy or ObjectProxy class. They should enable you to
do what you're looking for but you'll have to implement the
IEventDispatcher interface for the Binding to work.

Subject: [flexcoders] Watching a class full of bindable properties
I have a class marked Bindable with many properties. The class has a
read-only function which returns come custom XML based on the
properties. I want to fire a bindable event when any of the properties
change.
So far the ways that I've thought of doing it are:
1) Create a ChangeWatcher that monitors each individual property. (The
host would be this and the chain would be an array with every single
property listed in it.)
2) Write a setter and a getter for every single property, with the
setter dispatching a custom bindable event.
The problem with the first method is I'd have to list out every
property. Every time a property was added to this class I'd have to
make sure I updated the chain array. The problem with the second method
is I'd have to write setters and getters for every single property.
(The actual class has more than 20 properties.) It would make the class
harder to read.
Is there a way I could watch the properties for change with just a
couple lines of code?
[Bindable]
public class TheProperties
{
public var presetName:String=default;
public var presetThumb:String=;
public var presentationTitle:String=;
public var presentationThumb:String=;
public var presentationLogoURL:String=;
// many more properties...
[Bindable(event=propertyChangeEvent)] // necessary to get rid
of binding warnings
public function get xmlCode():XML {
// some funky stuff to create XML based on above properties
}
}
RE: [flexcoders] Dynamically referencing arbitrarily deep arrays?
Not sure I understand why you're doing this but you could try to
individually access each nested object until you get to the desired
object; then you access its content. I rewrote the loop of your code to
do this.
?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml;

t.one = [];
t.one.two = content;
// Works:
output1.text = t[one][two];
// Now what?
var indices:String = one.two;
var tmp:String = ;
var obj:Object = t;// Temporary variable
referencing your root object
for each (var item:String in indices.split(.)) {
if (!obj.hasOwnProperty(item)) break; // Verifies
that the object actually exists
obj = obj[item];
// Now obj references the nested object
}
output2.text = obj.toString();// obj
should now reference that last nested object

RE: [flexcoders] itemrenderer in popupMenuButton?
ItemRenderers are used for list based controls. When you want to customize the look and feel of buttons, you must do it through their skins. You can use a programmatic skin to do it. However, from your text, I think that what you want to do is actually add an icon to each item in the list shown by the PopupMenuButton. That you can do by changing the style of the menu through the popUpStyleName style or by directly accessing the display menu component through the popUp property. Give it a try. It may be a little bit harder to do but should be possible.

RE: [flexcoders] Use ChangeWatcher with dynamic Object?
Maybe you can use the ObjectProxy instead of Object.

RE: [flexcoders] as3 interface syntax ?
An interface is basically a contract between two classes. In the example below, the class containing the mentioned line doesn't care which class is passed to it from the _textFlow.interactionManager property, it just makes sure that it implements the interface (i.e. the contract). So, _textFlow.interactionManager probably returns an untyped Object and the command IEditManager() casts it so the compiler doesn't throw an error when the method applyParagraphFormat() is called. In other word, if the IEditManager() command was to be removed, the compiler would have choked out since _textFlow.interactionManager returns an Object and that applyParagraphFormat() is not a method belonging to a standard Object. Interface allows for polymorphism and is a very powerful tool in any OOP programmer tool belt. You definitely need to read up on it and understand it. You can find good tutorials on-line or just read the Programming AS3 section in the help.

RE: [flexcoders] BindingUtils question.
You can actually bind to a variable by also using the BindingUtils.bindProperty() method. You just need to you the this keyword. So: BindingUtils.bindProperty(dogNameText, text, this, myString); Don't forget to enclose your variable in double quotes since that last parameter must be a string. The only catch is that the myString variable needs to be a public property otherwise you'll get runtime errors. If you really want to keep myString protected or private, then you have to use the BindingUtils.bindSetter() method as it was earlier suggested by Rajan.

In your treeRendererFilter class, override the updateDisplayList method.
In there, set the position of your customerReportingFilter based on the

class, is made to be the entire lenght of the item renderer minus the
icons. So, you want to calculate the size of your
customerReportingFilter component, in the measure function, and in the
updateDisplayList function, you do something like:
override protected function updateDisplayList(unscaledWidth:Number,

RE: re: [flexcoders] Problem drag and drop
I tried to do it while modifying your code as little as possible.
Copying is a lot more complex than moving and it can become a nightmare
if you have children embedded inside your Title Window. I think that you
may also have to clean up the BitmapData used as a drag proxy image to
avoid memory leaks. There are not only one way of doing this and it
might not be the best way but it's a start.
Good luck!

RE: [flexcoders] Question from a C developper
Salut Christophe,
Other will definitely pitch in but here are some answers:
Is it possible to define a variable as a long ?
The data type is Number. It's a IEEE-754 double-precision
floating-point number.
How to program the overloading of an operator like the equal between 2
objects of a same class.
There are no operator overloading in AS3. You would have to code a
specific function (such as compare(a, b):Boolean) to achieve this. You
can only compare object instances using the == and === operators.
What is the equivalent of a structure ?
You can use the Object data type. Basically {pair1:value1,
{pair1:value1}. It is not a structure but can be used for its
replacement I guess. You can also just code a plain old class.
When I call a function with a parameter, did this parameter is
modified when I return from this function ?
All parameters are passed as reference except for the fundamental data
types (String, Number, int, uint, Boolean).
How to convert an int to a Number ?
Numeric types are implicitely converted into each other. However, you
can cast it like this Number() if you want to make it clear in your
code.

RE: [flexcoders] Question about binding and circular reference
The problem you are experiencing is caused by the fact that when the
player executes the line [ mf.foo = bar ], your text input is not even
created in your form yet. So, the foo-myText binding does nothing and
when the text input is finally created, the myText-foo binding executes
and thus overwrite what was in foo.
If you want to avoid this, you need to do:
protected var mf:MyForm = new MyForm();
mf.addEventListener(FlexEvent.CREATION_COMPLETE, formCreatedHandler);
addChild(mf);
protected function formCreatedHandler(event:FlexEvent):void {
mf.removeEventListener(FlexEvent.CREATION_COMPLETE,
formCreatedHandler);
mf.foo = bar;
}

Indeed, if I do this in the main app:

then myText is empty, probably because it's empty content is first

Of course it works if I use two vos: say voIn and voOut, binding them

RE: [flexcoders] Flex 3 Tree - Moving Nodes
I have done something similar lately except for the spring loaded opening mechanism. The problem that I saw with Alex Harui's approach was that you had to turn a leaf into a branch before being able to drop a node on it. That impacts the icons that represent the nodes and I still wanted a leaf node to be represented with a leaf icon up to the point where it contains children. If all your nodes (leaf or branch) have the same icon, then you could make all the nodes branches through a custom ITreeDataDescriptor. You'll have to live with having the small arrow to the left on every node. What I finally did was to overload some tree methods. If the drag drop is over the bottom half portion of a node, I highlight it and rewrite the parent and rowIndex properties of the _dropData property. That works well. You could extend the logic to open up the folder after the drop and add a spring loaded opening mechanism. I'm attaching some code but I had to clean it up to remove proprietary information. Not sure if it still compiles but that's a starting point :-) Hope it helps! TreeEx.as Description: TreeEx.as

RE: [flexcoders] Wicked Memory Leaks and Massive Loitering Objects
I like your humour Adrian! The loitering objects can be caused by many things. During my track down on leaks, I found out that most of the time, it was forgetting to set a property to null, not removing listeners as I expected, etc. Without seeing code, it's difficult to help you out properly. However, here are some things to ponder: * Allow for null values on all properties. When the null values are received, do a clean up and release all references. This is especially useful when you have bindings going on. * If you can't easily remove a listener, make it week by setting the last parameters of AddEventListeners() to true. * If you are using a Dictionary, allow for weak references: new Dictionary(true). * Item renderers do not release their reference to the data. You can built a helper function that can do this for you. (See attached file) * Alex Harui made a nice tutorial if you're not too familiar with the profiler ( http://blogs.adobe.com/aharui/2008/09/using_the_flex_builder_3x_prof.htm l) And be patient, at the end, you'll be able (unless there's a bug) to remove all bad references using the profiler.

RE: [flexcoders] I'm just not seeing it guys/gals... (events/scopes)
Your e-mail is not very clear. There are many ways to get the array collection to update. Anyway, if you are using a drop-in item renderer, I suggest that you access the listData property of the itemRenderer. listData has a property called owner. So you could have your item renderer dispatch an event using the owner property. This way, the event will be seen as coming from the list itself. so, from inside the item renderer: listData.owner.dispatchEvent(your event); and attach listeners to the list itself to get notified. http://geo.yahoo.com/serv?s=97359714/grpId=12286167/grpspId=1705007207/ msgId=136557/stime=1234359703/nc1=4507179/nc2=3848640/nc3=4836038
[flexcoders] And survey says: private VS protected VS namespace
I'm sure that a lot of us have tried over the years to extend some Flex controls. We all have soon realized that a lot of important methods are private and that if we want to tweak something, we have to copy these private functions into our derived class. Fortunately, there is the mx_internal namespace that sometime saves us many headaches. My question is: If you want to build something that's easy to extend from, what do you do? Have almost all methods protected? Use another namespace? When do you use static methods? I like the namespace twist but then, it also makes the methods and variables available to outside classes when they import and use the namespace. I know that sound design should alleviate a good portion of these but it's inevitable, developers will always try to use your work in ways you never thought of ... So, what's your take on this?

RE: [flexcoders] Re: Tree Control Drag and Drop Help
Glad I could help! I had to to change the tree a few days ago so it could allow droping nodes onto a branch. I spent a few hours figuring it out so if I was able to save you time then great. If you dig deep into the Flex Components code, you'll see that they often use mx_internal. Also, just as a side note. If you import the namespace and that there are no collision, i.e. no two variables share the same name, you don't need to prefix the variable name with it's namespace. So, you could have just written: var parent:String = event.dragInitiator._dropData.parent.label http://geo.yahoo.com/serv?s=97359714/grpId=12286167/grpspId=1705007207/ msgId=135844/stime=1233608798/nc1=4507179/nc2=3848642/nc3=5597441
RE: [flexcoders] Tree Control Drag and Drop Help
When a drag drop operation occurs on a tree, the drag drop handlers call the public calculateDropIndex() function. This function stores all the properties that you want in an mx_internal variable called _dropData of Object data type. So, make sure that your class import and use the mx_internal namespace and attach a listener to the tree's dragDrop event. In the event handler, look up the _dropData variable and specifically the parent and index properties. If this drop operation should not be allowed, call the preventDefault() method on the event. That should do the trick.

RE: [flexcoders] BindingUtils and ResourceManager Question
What we have done is to separate ourselves from the resource manager a
bit. We have created a new class that basically has a bindable property
called value. This class is passed the name of the string that is
localized in the resource manager and hooks to the resource manager. It
monitor for changes on the resource manager and when they are detected,
the class sends an event that triggers the binding. So, it can be used
directly in MXML or in the .as file by using the BindingUtils class.
In pseudo code (.as file):
var localizedProp:LocalizedProperty = LocalizedProperty.create(Bundle,
localized property);
BindingUtils.bindProperty( this, your variable, localizedProp,
value);
In pseudo code (.mxml file):
[Bindable] var localizedProp:LocalizedProperty =
LocalizedProperty.create(Bundle, localized property);

RE: [flexcoders] Re: Roles Based UI
And now to answer ilikeflex last questions ...
Yes you will need to store the mapping between permissions and roles. When you
create a new role, you need to have a UI that will help the user assign a list
of permissions. You can also create a role from a template that already has a
set of permissions assigned to it. You then just add or remove the required
permissions to customize the role. This approach, as stated earlier in the
e-mail trail, has the benefit of allowing to easily customize the UI for any
type of users but it has the drawback that you must develop a role/permission
model and all the UI that comes with it.

E.g.
mx:Button id=btndelete1 enabled=User.hasPermission

mx:Button id=btndelete2 enabled=User.hasPermission
('CanDelete') /
mx:Button id=btnAdd enabled=User.hasPermission('CanAdd') /
etc...
You can see here that two buttons can be displayed using the same
permission.

Hi
Do you mean to say that i should do something like this
mx:Button id=btndelete visiblieUser.hasAccess(btndelete)/
In the above i am passing the id of the component.
Then this means that i have to make some mapping between the

I think this will be more difficult to manage.
Let me know as you are already implementing it. If you could some

[flexcoders] Re-parenting Tree nodes using drag drop

RE: [flexcoders] Re: Big issue with keyboard mapping on Windows
I have a French Canadian keyboard mapping on my Windows machine and I can type all of the accentuated characters in any TextArea or TextInput. The only thing that I have witnessed is that I need to toggle on my French Canadian keyboard every time after the browser opens. It seems that Flash doesn't initially read the keyboard mapping correctly. As soon as I toggle the keyboard mapping on, once inside the browser, the keyboard works perfectly.

[flexcoders] Source Control in Flex Builder
Just throwing a line here to see if someone did this as I'm sure someone did at some point. I have a few projects in Flex Builder and all of them are under source control using the Visual SourceSafe Team Provider plugin for Eclipse. My problem is that I'm tired to manually refresh all the projects. Every morning, I have to highlight the project, right-click and select the Team - Refresh sub-menu. I would like to build an Ant Task that would automatically do this for all the projects. I saw someone using an Ant Task that was actually getting all the latest files from SourceSafe and then calling the eclipse.refreshLocal. I'm not sure about this approach as I believe that it could possibly start adding unwanted files in my projects since only the src folder is put under source control. I would rather be able to trigger the Team Refresh function directly from Ant and for a specific folder. Did anyone do something like this? Did anyone had success controlling the Team Provider plugin functionalities from Ant? And if you did, how did you work around the problem when getting the latest files for a Flex Library project? Each time I have to manually go and include the new files in the library through the Flex Library Build Path property of the project.
RE: [flexcoders] Dragging to Super Tab Navigator
It's not clear where you want the dragged image to appear. Is it on the tab itself or on the container contained in the SuperTabNavigator? If it's on the container, then just implement drag and drop operations for your container and that should do the trick. If you are looking to drag the image on top of the SuperTabNavigator's SuperTabBar and expect it to create a container that will hold the image, then it's a bit more complicated. The SuperTabNavigator, through its SuperTabBar handles the drag and drop operations but only of SuperTab controls. Anything else is ignored. If you want the SuperTabBar to handle other type of drag and drop operation, you'll need to extend the classes or listen to the drag and drop events of the SuperTabBar. If you use the mx_internal namespace, you can get a handle on the SuperTabBar of the SuperTabNavigator by using the method getTabBar() and casting the returned object to a SuperTabBar. Just remember that you cannot add an Image as a child of a SuperTabNavigator, only Containers can be child of this object. Hope it helps!
