Flex :: Event Metadata: Using Static Variable For "name" Attribute?
Jun 24, 2011
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.

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?

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. :)

Using e4x in flex:
var attr : String = "foo";
var xml : XML =
<resultSet>
<node foo="1"/>
</resultSet>;
How can I use the variable "attr" to access
xml.node.@foo
I thought I could do it with
xml.node.@[attr]
But this doesn't seem to work. How can I access this attribute by a dynamic value like this?
Both
xml.node.@[attr];
and
xml.node.attribute(attr);
work, as Constantiner suggested.
Updates:
Say I have an XMLList in this form:
var bar:XML =
<resultSet>
<node>value</node>
</resultSet>;
I want to filter the original xml above by matching "foo" attributes with the "value" from node in bar.
Essentially I want a sublist of the original xml such that
xml.node.@foo == bar.value
for each xml row in the original value
As Constantiner mentioned, I can filter the original list by the value in foo, but what if I want to filter on multiple values?
Can I do something like:
xml.node.(bar.node.contains(attribute(foo)) ? attribute(foo) : null);
Or perhaps a cleaner method instead of the null?

I have a flex app where I need to be able to access and modify component attributes using variable names.
eg, say I want to edit the text attributes of text label.
I am not sure what object or attribute will need to be updated until runtime.
Say I get passed the following variables:
var objId:String = "label1";
var objAtt:String = "text";
var objVal:String = "Hello World";
I need to take these and update the "text" property of label that has the ID "label1" to "Hello World".
I have tried different variations to accomplish this but am stuck One example is
this[objId][objAtt] = objVal;

I'm currently attempting at a little flash project where i have a movieclip travelling vertically downwards along the Y axis. When it hits a certain axis (in this instance, 500), I have a class written so that the movieclip then travels back upwards along the Y axis. I want the movieclip to change frame when it hits 500 along the Y axis (it's a movieclip of a bird flying towards the sea, and as it flies back up i want a fish in it's claws). I've tried looking into a method to do this, but nothing seems to work! I tried adding to following line of code into my class -
{
if(_y > 500){
enemy1.gotoAndStop (2);
}
but it gives me an error stating my movieclip is not a static attribute, and i have no idea what that means. I've tried putting a variation of this code into frame 1 of the movieclip itself, but it just skips straight to frame 2 without taking notice of any code relating to the Y axis.

How do you set a variable attribute of a xml element?This is what I expected to work:xmlElement.attribute(variableAttr) = "the variable attribute is set to this string";
However, I'm getting some error that this value can only be retrieved as a reference and not set.Ofcourse, the following does not work either as it will look for the attribute named "variableAttr" and not for the attribute named after the value of the variable variableAttr:
xmlElement.@variableAttr = "example";

I have an XML file loaded at run time.Among others, it contains several nodes which contain a name attribute and a value attribute.I want to be able to select name by value and vice versa.If I try and trace out a name by selecting its value, I get exactly what I expected:
[AS]
trace( "NAME: " + SiteModel.instance.constants.(@value==section).@na me );
[/AS]
But, and this is what I've been screaming at for most of the morning,if I try and assign that name to a variable, and trace the variable, I get epic fail:
[AS]
var n:String = SiteModel.instance.constants.(@value==section).@na me;
trace( "NAME: " + n );
[/AS]
Trying to trace that variable results in a TypeError:
Code:
TypeError: Error #1010: A term is undefined and has no properties.This is stupifyingly ridiculous in my opinion,

I tried many way to solve this error in mxml but failed anyway:
"Cannot resolve attribute 'colorChanged' for component type com.colorPicker.controls.colorclasses.ColorMap. AdvancedColorChooser.mxml"
<ColorPicker:ColorMap id="ColorSelector" modifier="{ColorModifier.value}" mode="{ColorMode}" value="{_value}" colorChanged=" {
handleColorChange(); <!-- defined in the script region below -->
[Code] .....
How should I define the "colorChanged"? Should I define colorChanged as an event in ColorMap.as? Like this,
internal function colorChanged(arg1:flash.events.Event=null):void {
return;
}
But I got syntax error parsing the mxml file.

I'm working on a stand-alone application and NOT a web-based application, so I'm trying to do this strictly with AS3, if possible. For example, if I have an XML file that looks like this:
Code:
<profile>
<username>Joe</username>
<password>Smith</password>
</profile>
How do I change the value of the USERNAME attribute via AS3?
I've tried something like this already:
var xmlData:XML();
...
xmlData = XML(event.target.data);
xmlData.profile.username = "Mary";
but when I open the XML file, it's not writing "Mary" in place of "Joe."

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 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.

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)
