[flexcoders] Re: Dual DataService components causing problems
Thanks for that Seth, its definately a step in the right direction. I have now removed the fds.swc from the module project's build path but i am getting a few compilation errors on VO classes i have defined to be used in the managed collection of objects... 1045: Interface IManaged was not found I think this is why i had to add the fds.swc to the project in the first place.

[flexcoders] Flash/Flex Component Kit and Dynamic Loading
I'm working with the Flash/Flex component kit and I have created some swc and swf files with a base class of UIMovieClip. All of the tutorials I've seen/read describe using the swc file to instantiate the Flash component in a Flex component. I have an application that requires these components to be loaded dynamically so I'm using a loader object to do this and I use the class name of the symbol that is exported in the SWF to instantiate the symbol. So far so good. My problem arises when I try to add an instance as a child to a Flex container. mxmlc throws a 'type coercion error' that my UIMovieClip does not implement IUIComponent. Reading flashdocs and flex component kit docs, however, it clearly state that UIMovieclip objects can be used just like any native Flex component. My work around at the moment is the create an intermediate UIComponent, add my Flash symbol instance as a child and then add this UIComponent as a child to the panel. This is okay for now but makes several things more complex. Anyone know what this is all about? Also, I've tried to dynamically load a SWF to be used a skin for a button, but this seems not possible. Can anyone verify if this can be done at all? Thanks.
[flexcoders] flash9 and sizes
Hi, I use as3 + sdk + FlashDevelop to do swf:s, currently trying Flexbuilder as I eventually would like to start using mxml. I am not completely sure how coordinates and sizes work. Say that I have a root Sprite 100x100 large; a child Sprite at x:50,y:50 of size 50x50. It seems that flash calculates a viewport of the child sprite and maximizes it to fit into the 50x50. So if the child sprite only contains a 10x10 bitmap, this bitmap will be rendered of size 50x50 in the root sprite. The root sprite did seem to bahave like this too until I got the advice to this.stage.scaleMode = StageScaleMode.NO_SCALE; this.stage.align = StageAlign.TOP_LEFT; In short, I've managed to confuse myself gravely and wonder if any has any reading suggestions?

Re: [flexcoders] Re: Use Cairngorm wihtout Dispatch
I'm not saying it's a major problem that we come across often, but when taking on other people's work, or working as a team it's something we have come across. We would expect all vars, methods, class, events to be named well, but we find it more efficient to error the project through changing a method name, than to do a find in files. We want to keep things as simple as possible. The point I was making as that just because events are used on the view instead of it accessing controller methods directly it doesn't necessarily de-couple them, since in most cases the view is relying on its events being picked up and acted upon. If my previous statement is true for you and your team, there's really no need to go down the event road, as it does introduces more complication and with it more time to implement. Just to clarify we don't take this approach on components, but we do for views/screens. On 5 May 2008, at 01:37, Jim Hayes wrote: I've not really had those problems myself Tink. I don't dispatch any standard cairngorm events, instead I have events that extend it and are (usually!) fairly well named to reflect what's happening. Maybe that's because for me they normally carry some data, and I like that data to be as strongly typed as is practicable. The command/delegate will usually follow the same naming, so I may have SaveBitmapEvent + SaveBitmapCommand + SaveBitmapDelegate, for example. So to find any particular event dispatch in my view, it's pretty easy to do a find in files on the project, though in practice I find I rarely need to. Likewise, finding the command it calls is pretty easy for the most part, as is the implementation in the delegate. Good point on the controller not listening, but I guess I've just got used to writing a shell version of my command, breakpointing it's constructor and checking it does get called when I expect it to before proceeding to fill in it's implementation. If not, then the frontController has it's fingers in it's ears shouting na na na I can't hear you :) It would be good if it could catch all cairngorm events and raise a warning if they were not registered, though. I have a feeling it wouldn't be too hard to extend it do that, but I've never felt the need myself. I'm sure we're both thinking don't make me have to think too hard, if at all, and I'm in broad agreement with you, but the 3 classes and controller entry approach does work for me (even if it is very tedious to write at the time). -Original Message- From: flexcoders@yahoogroups.com on behalf of Stephen Downs Sent: Sun 04/05/2008 14:08 To: flexcoders@yahoogroups.com Subject: Re: [flexcoders] Re: Use Cairngorm wihtout Dispatch I have to agree with MichNiu here. The CairngormEventDispatcher obsfucates the code. i.e. you come back to a project 6 months down the line, its difficult to find in the view where your CairngormEvents are dispatch. What is the difference of the view knowing what event it has to dispatch, to it actually knowing the method on the controller it was to invoke? Very little in my opinion, but the later enables you to very easily pinpoint all the calls from the view to a method on the controller, by just changing the name of the method on the controller, and looking at all the errors that will appear on the view. This makes things much easier to debug and therefore easier to maintain. You talk about making views re-useable, but if your view is dispatching CairngormEvents, you can guarantee it's relying on some action of the FrontController for it to work properly. If you FrontController doesn't listen to these events, your view won't work, therefore it aint re-usable, its relying on the FrontController acting upon the events is dispatches. We still keep a Controller unlike MichNui's implementation, but we cut out the use of CairngormEventDispatcher some time ago. Now when it comes to re-usable components, thats a different matter. Tink On 22 Apr 2008, at 03:53, ben.clinkinbeard wrote: One of the core principles of not just Cairngorm but MVC in general is for your views to be as dumb as possible. The less they know about models, services, etc the better. You've essentially taken the opposite approach. Creating reusable/generic views using your approach wouldn't really be possible. Also, Flex is an event driven architecture and events are another core aspect of creating loosely coupled application components.

[flexcoders] Child items in custom component
Hello!
I am currently a bit clueless regarding using Flex components. I am
currently trying to port a .NET component to Flex. Only I have some
problems. In a simplified form the problem is that I am trying to add
childs to the component. The idea is to use public method to add nodes
to the component. The code could be:
var node: MyNode = new MyNode();
node.width = node.height = 125;
myComponentInstance.addNode( node );
The addNode-method is basically contains:
public function addNode( node: MyNode ): void {
_nodeContainer.addChild( DisplayObject(node) );
invalidateDisplayList();
}
The _nodeContainer is a Sprite class which gets created in the overriden
createChildren-method. Now I would be expected that the MyNode-instance
(which just draws a simple rectangle 125x125) would be shown. Sadly
enough, this is not the case.
Does anyone know what should be done to get this working?
Yours,
Weyert de Boer

The best way is to have the change or click of your checkbox or button(toggle?) update the associated dataProvider item. Easy with XML, just set an attribute, like [EMAIL PROTECTED]delete.

RE: [flexcoders] DataGrid CustomItemRenderer Issue
Item renderers are recycled, and must be entirely data-driven. When you
add your child, you must update some property of the dataProvider item,
say, [EMAIL PROTECTED] = true.
Then in your set data() override, use the value of that property to
decide whether to either add or remove the text child.

I have a bindable data model implemented as a singleton, several properties of which are implemented as XML. My app uses binding and ChangeWatchers to respond to changes in this XML data. If I assign an entire xml to one of these properties, the property change is dispatched and my bindings fire and my watchers are called. But if I update an item in the xml, like set and attribute value or text node, it APPEARS that the events are not dispatched. This is unsurprising, as it is analagous to updating an item property in a Collection, for which itemUpdated() method exists. First, is the behavior I am seeing is expected? I know that XML dispatches ordinary events that fire bindings, but those events are not getting out of my model instance. Second, if the behavior is expected, is there some similar itemUpdated() functionality for XML? Tracy

Hello, everybody!
How to use addEventListener for File.createDirector y() on Adobe AIR?
I write code:
var dir:File = new File(e:\\) .resolvePath( myDir);
dir.createDirectory ();
dir.addEventListene r(Event.COMPLETE , someFunc); // Tooltip show me that this
event i can use for my parameter and I want to check if my new Directory
created then call someFunc()
function someFunc(event: Event):void{
var file:File = File.desktopDirecto re.resolvePath( test.jpg );
var newFile:File = dir.resolvePath( file.name) ;
file.copyTo( newFile, true);
}
but this code doesn't work. my someFunc doesn't execute. I see, my folder
creating with some pause, I get new folder after 2-3 seconds after execute
function and I want to check when my folder is created and after it copy to it
some files

[flexcoders] TextArea but no scroll bars showing up
Flex 2.01 This seems so dumb, but I can not figure this out. I am using Modules with layout=absolute. In a MXML file I have a TextArea where I have set the width=300 and height=35. mx:TextArea top=10 left=30 width=300 height=35/ I can add text beyond 2 lines, but no scroll bar is displayed. If I set the height=100% then the scroll bar shows up when I type text beyond 2 lines. I can also place it inside a VBox and set height=100%, but that just adds unnecessary code. That also causes other positioning problems. However, I want/need to set the TextArea's height. What am I missing? Is there a simple way? Thanks, Jack

RE: [flexcoders] Re: datagrid using button or checkbox wHat Code to Trigger
Ignoring LCDS and Blaze DS (which perhaps you should look into), Flex
can pass data to the server via the same protocols that it gets it,
namely WebService, HTTPService or RemoteObject. Since you used the word
POST, presumably you are using HTTPService.
What you pass over that protocol is up to you, but is most often xml.
If your dataProvider is XML (or is an XMLListCollection backed by XML),
you can send the data to the server by doing:
myService.contentType = application/xml
myService.send(xmlData);
Note: I typically use the default content type and do:
myService.send({xmlstring:xmlData.toXMLString()}); //then parse the xml
string on the server.
But that opnly gets your data to the server. Aside from LCDS or
BlazeDs, there is no built-in functionality to determine what needs to
happen with that data on the server.

[flexcoders] Pay-to-Play Credit Card Processors
Hello All- I am prototyping an online application that will require users pay-to- play. That is, users can purchase chunks of time to gain access to the application's functionality. My application is being developed using Flex3 on the front, ColdFusion8 in the middle and SQL Server 2005 on the back. Ideally I would like to integrate cc payment seamlessly. If the user gets close to running out of time they can quickly purchase with a stored profile and then seamlessly pick up where they left off. Does anyone have experience with vendors who provide plug-in cc processing service or shrink-wrapped components for this kind of pay-to- play functionality? Easy integration with the Flash Player 9 a BIG BIG plus, but not necessary. Thanks And Regards -Naga

[flexcoders] Fast updating of image.source
I've got a sequence of images loaded in Flex - for this example let's say I've populated an array (imageArray) with new Image objects. I've got an Image control (myImage) whose source is set on applicationComplete. During the application run, I'd like to be able to set the source of the image control dynamically (in this case, based on mouse position) to the source of one of the objects in the array. For instance: myImage.source=imageArray[0].source; The problem is, when I change image source there's a brief flash (no pun intended) when the image control updates - it seems to briefly show the background of the parent control (in this case a canvas with a solid color). This makes for a jarring transition between each image as it's loaded. I get the same effect even in the simplest of cases - just setting myImage.source explicitly, forgetting about the array. How can I update the source of an Image control without this strobing effect? Or am I going about it the wrong way? My Flex experience is limited to a few months of frontend UI development - lots of data binding and layout - and this is a new one on me. Thanks for any help, Roger Howard
[flexcoders] Checkbox as a headerRenderer
I am implementing a checkbox as a headerRenderer:
public class CheckBoxHeaderRenderer extends CheckBox
{
public function CheckBoxHeaderRenderer()
{
super();
addEventListener(click, clickHandler);
}
override protected function clickHandler(event:MouseEvent):void
{
super.clickHandler(event);
}
}
I need to be able to communicate to a column that would have that
header. I need to enable/disable it, as well as reset column's data.
Any idea?
Thanks
RE: [flexcoders] Combo Box trying to get a deep data...
Setting a ComboBox to show a selectedItem is not built-in. You will need to loop over the dataProvider for the CBO droplist, compare the current value to the value in the appropriate dp item property, then use the loop index to set the selectedIndex. This is not difficult. If you need to do it a lot, extend combobox. I have an example of this on www.cflex.net http://www.cflex.net/ . Note that it is a bit complicated, because I wanted to be able to get the comboBox options from either the dataProvider item itself or from an external DP. The issue is further complecated because one must be able to specify which property in the droplist dataProvider to use to compare values. A one-off for a specific use case is much simpler. Probably that is why this is not built-in.

Re: [flexcoders] Child items in custom component

Hello!
I am currently a bit clueless regarding using Flex components. I am
currently trying to port a .NET component to Flex. Only I have some
problems. In a simplified form the problem is that I am trying to add
childs to the component. The idea is to use public method to add nodes
to the component. The code could be:
var node: MyNode = new MyNode();
node.width = node.height = 125;
myComponentInstance.addNode( node );
The addNode-method is basically contains:
public function addNode( node: MyNode ): void {
_nodeContainer.addChild( DisplayObject(node) );
invalidateDisplayList();
}
The _nodeContainer is a Sprite class which gets created in the overriden
createChildren-method. Now I would be expected that the MyNode-instance
(which just draws a simple rectangle 125x125) would be shown. Sadly
enough, this is not the case.
Does anyone know what should be done to get this working?

Weyert de Boer
RE: [flexcoders] Child items in custom component
There are rules for what children can be added to what parents. Is it
possible you are not following those rules? sprite is a much lowe

you are adding?
Alex has posted these rules multiple times. Something like:
Container can accept container or UIComponent, UIComponent can accept
anything, ... etc I do not know whare sprite fits into that.

RE: [flexcoders] Child items in custom component
I found one of Alex's posts. Here is the text:
Once a month this issue comes up. Because there is no function
olverloading in AS3, we can't change the parameter list of addChild, but
basically, frameworks have rules and the rules for Flex are:
Navigator children must be Containers
Container children must be IUIComponents
UIComponent children can be anything.
I swear I replied to this thread two days ago, but answer is to
instantiate a UIComponent and addChild your sprite to it.

I have found no documentation that says the scroll bar will only appear if is contained within a container and/or the height is set to a percentage.

RE: [flexcoders] TextArea but no scroll bars showing up
I thought you were setting the text programatically, rather than typing,
apologies for that.
I just checked it (in flex 3), if the height of the textArea is greater than 40
pixels then scrollbars do appear when you type, but not if = 40.
If you look at the source for textArea it appears that this is hardcoded :
override public function get verticalScrollPolicy():String
{
return height = 40 ? ScrollPolicy.OFF : _verticalScrollPolicy;
}
I can only presume to allow at least some space for the scrollbar to be
rendered.
If it *has* to be 35 pixels high then you could try extending textArea I
suppose, otherwise try 41 !

mx:TextArea top=10 left=30 width=300 height=35/
I can add text beyond 2 lines, but no scroll bar is displayed.
If I set the height=100% then the scroll bar shows up when I type text
beyond 2 lines.
I can also place it inside a VBox and set height=100%, but that just
adds
unnecessary code. That also causes other positioning problems.
However, I want/need to set the TextArea's height.
What am I missing? Is there a simple way?
Thanks,

OK here's what i did to keep my nodes open.
un my update function i call preventDefault() to stop the expected operations.
then i manually build using updated data my object instances
then search the original objects till i find my matching object
overwrite the orginial object with the new instance
then run a refresh() on the dataprovider.
This appears to be working for me and it is having the expected

Scott and Jonese:
I am currently trying to deal with the same issue. I was
actually ALMOST there, but I think I have discovered a bug in Flex.
So the problem: Keeping the AdvancedDataGrid nodes that were already
expanded, open after a filter and refresh (specifically
a 'GroupCollection' refresh).
First, I got a nice array of objects containing the 'nodes' for the
grid nodes that were opened, adg.dataProvider.openNodes
Next, I did the filter and gc.refresh().
The final step was to iterate through all the nodes, find out which
ones had the same GroupLabel, and expand them
using adg.dataProvider.openNode(node:Object).
This is where I ran into problems. When I tried to re-open a node
using openNode, the node would expand, but the nodes below it would
not be in the right tree level (it seems as if they were stepping
down in level one by one, even though they were supposed to be all on
the same level below it). Now here is a real kicker! If I go to
click on anything in the grid after that, the display automatically
corrects itself! So odd.
If anyone has seen the same thing, or know what I'm even talking
about please let me know. Thanks!

incorrectly
somehow. Based on my thought that I have different objects in

than I did before I figured I could just save off the value of

approach
is that I have not yet been able to figure out how to iterate

Any help in getting my previously open items to re-open is greatly

[flexcoders] MessageBroker won't return control after routeMessageToService()
Well, Here is the report after I've traced the errors down.
I've noticed that when my custom java message adapter halts BlazeDS'
messaging still runs. Several diagnostic applications indicate the
durability of BlazeDS messaging.
I have however tracked down the source the halting of my java message
adapter thread to be the MessageBroker...
My custom message adapter is multithreaded in that it manages two
tasks: One thread listens for messages from a server and then starts a
fire-and-forget messaging thread that then packages and routes the
message into an AsyncMessage for broadcast to BlazeDS before dying.
Traces indicate that after about 6 days of reliable message routing
the messaging threads generated by my listener thread start halting at
the msgBroker.routeMessageToService(msg, null); method call. (Trace
statements to console halt after Trying to routeMessageToService).
public void sendMessage()
{
System.out.println(name+ Connecting to MessageBroker);
msgBroker = MessageBroker.getMessageBroker(null);
System.out.println(MessageBroker.getId() = +msgBroker.getId());
String clientID = UUIDUtils.createUUID(false);
msg.setClientId(clientID);
msg.setMessageId(UUIDUtils.createUUID(false));
msg.setTimestamp(System.currentTimeMillis());
System.out.println(name+ Trying to routeMessageToService);
msgBroker.routeMessageToService(msg, null);
System.out.println(name+ Successful message route);
}
That is to say that msgBroker's routeMessageToService() method call is
not returning and the messaging threads are all halting and piling up
in the JVM. After about 4000 of these halted messaging threads piling
up the JVM runs out of memory and the listener thread can't
instantiate any more messaging threads and the whole thing comes to a
halt.
You can say that my problem is thus: MessageBroker's
routeMessageToService() method stops returning control to my message
thread after about 6 days halting it until the unsent message threads
pile up leading up to an out of memory crash.
I'm working on a fix that will kill the halted message thread if it
runs longer than a few seconds. This should aleviate the thread
traffic jam but I don't know if the MessageBroker will start routing
messages again. I don't know why it stops either.
Hope you could shed some light on this.
Best,
Justin

Hi,
I've built a GIS FLEX application that uses blazeDS' messaging
capability to push location (latitude/longitude/geocode) info to
flex
clients.
The message producer is a custom Java bootstrapper and adapter that
configures the messaging destination endpoints upon server startup.
The destination runtime config java bootstrap method for our
fleet_demo destination looks like this:
public void initializeDestinations()
{
String destinationId = fleet_demo;
String serviceId = message-service;
MessageBroker broker = MessageBroker.getMessageBroker(null);
MessageService service = (MessageService)
broker.getService(serviceId);
MessageDestination destination = (MessageDestination)
service.createDestination(destinationId);
destination.addChannel(my-streaming-amf);
destination.addChannel(my-polling-amf);
ServerSettings serverSettings = new ServerSettings();
serverSettings.setMaxCacheSize(1000);
serverSettings.setMessageTTL(0);
serverSettings.setDurable(false);
destination.setServerSettings(serverSettings);
if (service.isStarted())
{
//initialize and run the destination
destination.start();
}
}
The bootstrapper also spawns a separate thread that continuously
receives location data from our server and packages it into an
AsyncMessage and routes it to the appropriate destination using a
method similar to this:
private void sendMessage(latitudeFromServer:double,
longitudeFromServer:double)
{
MessageBroker msgBroker = MessageBroker.getMessageBroker(null);
String clientID = UUIDUtils.createUUID(false);
AsyncMessage msg = new AsyncMessage();
msg.setDestination(fleet_demo);
msg.setHeader(latitude, latitudeFromServer);
msg.setHeader(longitude, longitudeFromServer);
msg.setClientId(clientID);
msg.setMessageId(UUIDUtils.createUUID(false));
msg.setTimestamp(System.currentTimeMillis());
msgBroker.routeMessageToService(msg, null);
}
Now I start up the server and the bootstrapper initializes the
fleet_demo endpoint and
[flexcoders] Re: Use Cairngorm wihtout Dispatch
The point I was making as that just because events are used on the view instead of it accessing controller methods directly it doesn't necessarily de-couple them Agreed. Also, I don't like being restricted to only being able to register events types to command classes to a Front Controller that is created in the view. Registering the controller in the view means to reference it at runtime i have to go through the view. Common sense tells me in MVC it would be better if the controller was created by the model, not the view. --- In flexcoders@yahoogroups.com, Stephen Downs [EMAIL PROTECTED] wrote: I'm not saying it's a major problem that we come across often, but when taking on other people's work, or working as a team it's something we have come across. We would expect all vars, methods, class, events to be named well, but we find it more efficient to error the project through changing a method name, than to do a find in files. We want to keep things as simple as possible. The point I was making as that just because events are used on the view instead of it accessing controller methods directly it doesn't necessarily de-couple them, since in most cases the view is relying on its events being picked up and acted upon. If my previous statement is true for you and your team, there's really no need to go down the event road, as it does introduces more complication and with it more time to implement. Just to clarify we don't take this approach on components, but we do for views/screens. On 5 May 2008, at 01:37, Jim Hayes wrote: I've not really had those problems myself Tink. I don't dispatch any standard cairngorm events, instead I have events that extend it and are (usually!) fairly well named to reflect what's happening. Maybe that's because for me they normally carry some data, and I like that data to be as strongly typed as is practicable. The command/delegate will usually follow the same naming, so I may have SaveBitmapEvent + SaveBitmapCommand + SaveBitmapDelegate, for example. So to find any particular event dispatch in my view, it's pretty easy to do a find in files on the project, though in practice I find I rarely need to. Likewise, finding the command it calls is pretty easy for the most part, as is the implementation in the delegate. Good point on the controller not listening, but I guess I've just got used to writing a shell version of my command, breakpointing it's constructor and checking it does get called when I expect it to before proceeding to fill in it's implementation. If not, then the frontController has it's fingers in it's ears shouting na na na I can't hear you :) It would be good if it could catch all cairngorm events and raise a warning if they were not registered, though. I have a feeling it wouldn't be too hard to extend it do that, but I've never felt the need myself. I'm sure we're both thinking don't make me have to think too hard, if at all, and I'm in broad agreement with you, but the 3 classes and controller entry approach does work for me (even if it is very tedious to write at the time). -Original Message- From: flexcoders@yahoogroups.com on behalf of Stephen Downs Sent: Sun 04/05/2008 14:08 To: flexcoders@yahoogroups.com Subject: Re: [flexcoders] Re: Use Cairngorm wihtout Dispatch I have to agree with MichNiu here. The CairngormEventDispatcher obsfucates the code. i.e. you come back to a project 6 months down the line, its difficult to find in the view where your CairngormEvents are dispatch. What is the difference of the view knowing what event it has to dispatch, to it actually knowing the method on the controller it was to invoke? Very little in my opinion, but the later enables you to very easily pinpoint all the calls from the view to a method on the controller, by just changing the name of the method on the controller, and looking at all the errors that will appear on the view. This makes things much easier to debug and therefore easier to maintain. You talk about making views re-useable, but if your view is dispatching CairngormEvents, you can guarantee it's relying on some action of the FrontController for it to work properly. If you FrontController doesn't listen to these events, your view won't work, therefore it aint re-usable, its relying on the FrontController acting upon the events is dispatches. We still keep a Controller unlike MichNui's implementation, but we cut out the use of CairngormEventDispatcher some time ago. Now when it comes to re-usable components, thats a different matter.

I can add text beyond 2 lines, but no scroll bar is displayed.
If I set the height=100% then the scroll bar shows up when I type text
beyond 2 lines.
I can also place it inside a VBox and set height=100%, but that just adds
unnecessary code. That also causes other positioning problems.
However, I want/need to set the TextArea's height.
What am I missing? Is there a simple way?
Thanks,
Jack

Re: [flexcoders] Fast updating of image.source
Hi Roger, Roger Howard wrote: I've got a sequence of images loaded in Flex - for this example let's say I've populated an array (imageArray) with new Image objects. I've got an Image control (myImage) whose source is set on applicationComplete. During the application run, I'd like to be able to set the source of the image control dynamically (in this case, based on mouse position) to the source of one of the objects in the array. For instance: myImage.source=imageArray[0].source; The problem is, when I change image source there's a brief flash (no pun intended) when the image control updates - it seems to briefly show the background of the parent control (in this case a canvas with a solid color). This makes for a jarring transition between each image as it's loaded. I get the same effect even in the simplest of cases - just setting myImage.source explicitly, forgetting about the array. How can I update the source of an Image control without this strobing effect? Or am I going about it the wrong way? My Flex experience is limited to a few months of frontend UI development - lots of data binding and layout - and this is a new one on me. What about storing an array of Image components in the array rather than the urls... put them all on the canvas and the just set visible for the one you want to display. I had to do a similar thing once when i wrote a flex lake applet. YMMV. http://users.on.net/~shaun/FlickrLake/FlickrLake.html http://users.on.net/~shaun/FlickrLake/FlexLake.as cheers,
[flexcoders] Modules the way to go?
Hey guys, Im actually working on an application that controls several Flex made apps. It's like a desktop manager application that manages several widgets. The applications running in the desktop manager are modules set on the server, that are loaded and unloaded per user request, but when a user have 6 or more Modules opened at the time the desktop manager becomes really slow, and the explorer can even crash! Am I working the modules the wrong way, or this component really adds that kind of weight to the computer? Is there another way to go? Thanx a lot guys...
[flexcoders] Query on SWC
Hi, I have created a SWC file of various components. Adding the SWC to Flex Builder project makes the components visible in the Components Window (in Flex Builder) under the folder named Custom. Instead I would like to display it under a different category in the Components Window. Also some of these components have certain properties that would appear in the Properties view. As of Flex Builder 2, this Meta data had to be stored in xml files within Flex Builder plug-ins. However, I believe that there are easier ways to do the same using Flex builder 3. I think some of this meta data can be added to the swc file itself. Could anyone throw some light on how this can be achieved? If not in Flex Builder, are there any other tools or procedures that can lead to an easier solution? Thanks Regards, Sudha. Check out the all-new face of Yahoo! India. Go to http://in.yahoo.com/

A module is as big as you make it. I'd be checking to make sure it is small and releases unused resources.

l
while flex example shows how to assign a date into a text field
what if someone wanted to reuse the date function routine with 20 text
box's ...?
Could i pass a variable containing the name of the object to now use in
like so
public function useDate(eventObj:CalendarLayoutChangeEvent,
MYVARIABLEPASSEDIN):void {
// Make sure selectedDate is not null.
if (eventObj.currentTarget.selectedDate == null) {
return;
}
composedatetext.text =
(eventObj.currentTarget.selectedDate.getMonth()+1) +
/ + eventObj.currentTarget.selectedDate.getDate()
+
/ +
eventObj.currentTarget.selectedDate.getFullYear();
MYVARIABLEGOES HERE.visible=false;
}

Subject: [flexcoders] Checkbox as a headerRenderer
I am implementing a checkbox as a headerRenderer:
public class CheckBoxHeaderRenderer extends CheckBox
{
public function CheckBoxHeaderRenderer()
{
super();
addEventListener(click, clickHandler);
}
override protected function clickHandler(event:MouseEvent):void
{
super.clickHandler(event);
}
}
I need to be able to communicate to a column that would have that
header. I need to enable/disable it, as well as reset column's data.
Any idea?
Thanks
