Flex :: Adobe Flex - Event MetaData Tag And Clone Method?
Jul 22, 2011
overriding clone() while creating custom events?I read in the Flex cookbook that we need just in case we want to redispatch this event. Does this exactly means that when we want event to be bubbled up the display hierarchy , at that time our custom cloned event should be dispatched and not the Event object.
second - whats the need of metadata tag -
[Event(name="modelEvent", type="com.abc.data.model.ModelEvent")]
public class LoginModel extends EventDispatcher
I understand we need to extend EventDispatcher in case we want to dispatch evnet from class.. but In what cases i would need to specify the MetaData TAg
Third is.. If i write -- "dynamic customEventClass extends Event".. Is there any use of Dynamic i can make?

I am trying to duplicate a flex component at run time. For example if I have this:
mx: Button label="btn" id="btn" click="handleClick(event)"/>
I should be able to call a function called DuplicateComponent() and it should return me a UI component thts exactly same as above button including the event listeners with it.

we have following class
[Code]...
If you run these, you'll notice that the MXML-component can't hear the event. The question is simple, is there some way of getting the Event-metadata tag to work WITHOUT extending EventDispatcher? I would like to keep this class independent and use object composition as much as possible. And no, I don't want to use ActionScript addEventListener in the MXML-file. It doesn't tell the developer anything like good old Event metadata tag, and besides, that is not the point of this example. :)

I want to use the Event metadata tags to show what types of event my control will dispatch. The syntax looks like:
<fx:Metadata>
[Event(name="eventName", type="MyEvent")]
</fx:Metadata>
It seems like a best practice in Flex/Actionscript to define static variables that define event names like so:
public class MyEvent extends Event
{
public static const EVENT_NAME:String = "eventName";
// Other stuff..
}
It's a great practice since the event name can change easily and not have to be modified throughout the code. So my question is: Is there any way to use this static const in my metadata event tag? I can't seem to do something like this:
<fx:Metadata>
[Event(name="{MyEvent.EVENT_NAME}", type="MyEvent")]
</fx:Metadata>
Am I just ignorant of the proper syntax to do this, or is it impossible? Seems like it's just asking for hard to find bugs if someone decides to change the const since it is not strongly typed here.

I just have a one quick question on Timer and TimerEvent (flash.events.TimerEvent & flash.utils.Timer) of Adobe Flex.I am currently working on a project wherein I need to occasionally change speed, stop and play an swf animation (loaded to a loader and instantiated as a ByteArray).Example, I have a moving car (swf animation) running at 40kph. Then I have a button which will change the speed by increments of 40kph. SO basically, whenever I hit the button, the playing car should change speed by the increment. The difficult part is, I already had this working in Adobe Flex but it doesn't change the speed yet. I mean, it only moves by the keyframe interval I set when I created the swf file on flash (which is, to say, 30 frame interval per keyframe).
So in short, I just need to make the speed change depending on how many increments I asked it to change. A colleague told me to use Timer and TimeEvent of Flex but I can't seem to quite get the hang of it since I'm still new to the ActionScript world.

Multiple axis creation via MXML works fine:

But when I'm trying dynamically create horizontal and vertical axis then I'm getting extra axes. I believe this is Adobe bug. How I can fix this behavior?

I created a list control at runtime as following:
[Code]....
//Where myDataArray is an ArrayCollection consisting of my Custom ValueObjects. When i execute the code it displays my list with custom item renderer, which is fine. But when bring my mouse over it, it doesn't give any colour highlight which means it is not selecting. Secondly, when i click on any of the list item, it doesn't dispatch any change event. I tried a lot but couldn't understand it.

I just would like to know how can I dynamically change a label's values while on mousedown.I basically have a mousedown event and I also have two labels in my application. What I would like to happen is to get the current x and y position of my mouse pointer as I move my mouse through the screen and changing the values of the labels into the values of the current x and y coordinates of the mouse pointer.
protected function object_mouseDownHandler(event:MouseEvent):void
{
curX = this.mouseX;[code]........
However, what this code does is that it records the coordinates of my mouse as it moves across the screen. What i want now to do is just to get the coordinates of the mouse while event is on mouseDown. What i'm thinking is to call the mouseDown event and ask it if the mouse is currently down, if it returns true, then i'll start recording.

set some filters on the bitmap after it has been loaded.During development (Debug mode), everything worked and the even has been fired just fine.But now I switched to Release mode and the complete event doesn't fire anymore.To load the image, I set the source property of the image to an URL that points to a PNG image. That does still work in release mode, so the image appears correctly.It's just that the "complete" event doesn't fire, no matter what I try.

OK, from what I know actionscript in Flex runs asynchronously. I need the ability to run a method in a loop synchronously. Consider this code:
public class CustomerContainer extends VBox
{
public function CustomerContainer ()
{
[Code]....
This is not my exact situation as it is a bit more complicated to explain here. There is an abstract class and several custom view objects derived from it. Some of the views are dependent on others being completed first but I cannot seem to order them in the correct order. TIMERS are not an option. Probably not explaining this correctly.

I know that it is possible to add swf metadata to the compile command as a command option, but I can't find any documentation on how to access these metadata within the actionscript during runtime. We're trying to add a version number to the swf during compile time and then somewhere in our app we would retrieve it during runtime, here is the command example to add the description metadata.
mxmlc -description "version 1.2.3"
I know the swf metadata is used by search engines and other utilities to gather information about the SWF file, but surely you should be able to retrieve them in the actionscript during runtime?

I'm trying to embed a font in Flex and the code I'm using looks the same as the example, but throws an error. This is the code I've written:
[Embed(source="data/posca_mad_thrasherz/posca_mad_thrasherz.ttf",
fontName = "fontGraffiti",
fontWeight = "bold",
mimeType="application/x-font")];
private var funFont:Class;
But I get the error, "Metadata requires an associated definition." I can't seem to get rid of it.

I have a situation where a simple query against a table is returning incorrect values in Flex, but not in other GUI front-ends to SQLite.
select title from ttl where ttl.ttl = 140 // ttl is also the column name of the PK column
is returning the title that belongs to the row whose PK = 1400.
ttl.ttl is defined as int datatype.
Again, the problem manifests itself only in Flex, not in other GUI front-ends to SQLite, which are returning the correct title value.

I saw that you can embed meta-data into images very much like you can in mp3s, here.
Can someone point me to a tutorial of how to embed and read this sort of information w/ photoshop and flex together? I really wouldn't know where to start... Tried googling but I'm not sure I have the right keywords down.

I have an actionscript, which makes a dynamic image wall. It gets parameters from FlashVar and changes the width and height dynamically.
When I use
[SWF(width="584",height="290")]
It's fully centered, but when I remove it, it's appear ~+50px from left. How can I set dynamically the SWF metadata or what I need to set for the correct view?
Top of the picture with SWF tag and the bottom is without SWF tag.

I am working over a program that needs to extract meta data from music files in different formats. It was easy for MP3 format, but there is nothing for other formats.I made a research, there is a lot of software for extracting meta data - but no source code or algorithm. There are open source projects, they use their own libraries, but I was not able to find something for Flex (Action Script)

I've doing a bit of "training" at working with Flex and Remote Data from XML files.This is my HTTPService
<mx:HTTPService id="loginData" url="com-handler/basic.xml" showBusyCursor="true">
</mx:HTTPService>
I have a button and when its clicked its call a function, that calls loginData.send and does a little IF condition, that IF condition relies on the data returned by loginData.The condition doesn't work because its called right next to the loginData.send, and .send method still didn't returned the values from the XML file. But if you click it a second time a second after the first click the IF condition works.So to deal with i wanted to do a eventListener so that when loginData.send returned the data from the XML it fires up the IF condition. But i don't know how to do it.
