Flex :: Add Dynamic Properties From String List?
Jan 1, 2011
I have the following problem in AS3. I have a string like this one: "prop1:val1,prop2:val2,..."; I want to split and parse the string to obtain a dynamic object like this one: {prop1:"val1", prop2:"val2"}.
The simple way to solve it is to cycle through the string values and to do[code]...
Since I know the property names I expect, this works for me, but doesn't seem to be an elegant solution. I'm wondering if there is another way in as3 (similar to the reflection api in java).

I'm trying to make a simple flash application providing interface for taking tests as a high school assignment. One of the requirements is to use an XML file as data source.Now, having a List component bound to the XML file with questions consisting of data such as question body, question type (ie. single choice, multiple choice, open, image etc.) and possible answers (where applicable), I was wondering if I could add some additional data (and what is the best possible way to do so) to each question upon its transfer to the List component.
I am trying to achieve two main goals with this: firstly, to mark the questions to which an answer has already been given, like with such code in ItemRenderer class:
<s:Label color="{data.color}" text="{data.label}"/>
Where data.color would be set whenever the user gives an answer to a question.
Secondly, while at it, I thought of such possibility as a great way to store answers given to particular questions. In this case, the Class of the answer object would have been Object, since there has to be many type of questions (where the answer could also be a Bitmap for example).

i have a question while reading Flex 4 Cookbook i came across the method to dynamically adding control to the container controls but nowhere i came across with how to provide them with the dynamic properties and events like they have created a button dynamically inside a group control but what good a button be if i cannot give it an event dynamically. in the same way i want to add a tree view inside a vbox but what good that be if cannot provide a data provider to it dynamically.actually i am creating an web application where i add the tree view to a vbox and i want to the data provider should also be dynamic depending upon the option i have selected in the combo box.

I have a list control in a component mxml file. I have created a function in main mxml file, I want to input a text string and add it to this list. How can I do that. Currently using this code
public function add(event:MouseEvent):void {
var name:String = mytextinputid.text;
currentState = 'ChatScreen';
mylist.____
}
Note that this function is in main and the mylist list control is in component mxml.

I have an Flex-Object with for example 3 properties.
myObj.prop1
myObj.prop2
myObj.prop3
I like to generate 3 Comboboxes to show the data.
No problem if I do it hardcoded in sourcecode.
But how can I find the prop1 to prop3 at runtime?
If next time I have 5 properties with different name it should generate 5 combos.

I am having a hard time understanding for...in loops. I have seen David use it in his signature, and I understand what the loops is doing, but only from the context of the rest of the signature. If somebody could explain how the for..in loop works, I'd be greatful. Here's what I know:
PHP Code:
for (proprtyThing in objectThing) {
trace (proprtyThing);
}
My understanding of this loop tells me that if I run it, I'll get a list of all the properties of the object named objectThing....but this makes no sense to me!!

I am working on an enterprise application and creating a base class for some stage components that has knowledge of the class extending it. More specifically, I need a way to loop through the inspectable properties in a class file and place the names of these variables into an array. For example:
Code:
[Inspectable(name="My First Variable", type="String", defaultValue="")]
private var _myVar1:String;
[Inspectable(name="My Second Variable", type="String", defaultValue="")]
private var _myVar2;

Does anybody know of a website that gives a full list of all as3/cs4 methods, properties, keywords, classes, etc?
I bought a book on beginning AS3, but it only introduces some properties and methods as it uses them in examples.

I have an engine I created a while back that loads objects into a container based on XML data. A really quick example of the XML would be like this:
<level>
<object cname="enemies.Robot">
<pos x="200" y="400" layer="mobiles" />
</object><object cname="Player">
<pos x="12" y="89" layer="mobiles" />
</object></level>
I have a class Environment that has a method loadLevel(data:XML) which I parse the XML through, then the function runs through the XML finding all object nodes and uses getDefinitionByName to determine which Object I want to create based on object.@cname. From here, I have to manually define each property based on the XML like so:
obj.x = xml.pos.@x;
obj.y = xml.pos.@y;
etc.
I was wondering if there's an inbuilt method for setting a property based on a String. By this I mean something like so:
var mc:MovieClip = new MovieClip();
mc.someInbuiltFunctionThatSetsAProperty("alpha", 0.5);
This way I could change my XML to be more like so:
<object cname="Player">
<props>
<x>200</x>
<y>221</y>
<alpha>7834</alpha>
<health>Something</health>
<power>3</power>
</props></object>
And iterate through all the children of props to set all of my properties on the fly. I know if I create an Object and set properties within it like so:
var obj:Object = {
var1: "hello",
var2: "there",
name: "marty"
};
That you can then iterate through names/values using the for(String in Object) loop like this:
var i:String;
for(i in obj){
trace(i + ": " + obj[i]);
}
/**
* Output:
* var1: hello
* var2: there
* name: marty
*/
Surely there's a way, as here's an example of identifying a property using a String:
var ar:Array = [new MovieClip(), new MovieClip()];
ar.sortOn("alpha", Array.ASCENDING);
So just to make my question more to-the-point: I want to be able to get and set properties that I can identify using a String.

I have say 50 movie clips on the stage. each has a name like "button1", "button2" etc and I want to move each one using a for loop instead of hard coding "button1._x = 50"
When I try this it doesn't work.
Code:
var buttonName = "button1";
buttonName._x = 50;

I have an array that lists movieclips.When I add a movieclip to the stage, I want to add it to the list (not as a string.) I use a string variable and add _root. to the beginning of it to do this. Unfortunately it lookes for the variable itself instead of what string it stands for when I run it.
movieList = new Array();
if (duplicate) {
_root.enemy.duplicateMovieClip("enemy"+i, i);[code].....

Here is a snip from within my code:
[Code]...
The 'recommendations' dataProvider is an ArrayCollection of String, which are generally sentences about as long as this one. By setting the variableRowHeight and wordWrap properties as shown, if a sentence is too long to fit on a single line, everything works fine- the row expands and the messages show on two lines, or occasionally three.
The space allocated for this panel within the entire canvas means if the total text size of 'recommendations' exceeds six lines, I need for the entire list scroll. This is also working just fine. The trouble is when using the mouse wheel to do the scrolling- Flex scrolls both the entire list and the single item where the mouse is hovering. Often this results in only the second half of a sentence being visible. Non-programmer friends I have asked to look at this noticed this, and tell me it as a problem. If a user does not notice the dual scrolling, and sees only a fragment of a sentence, it will be perceived as an error in the application.

I'm trying to animate a list as I delete the top row. All the examples I can find use itemsChangeEffect to bind to the effect, but this property exists only in MX lists, not spark lists.
Any idea how I can get the same effect done in Spark Lists?
I'm trying to remove the top most item in the list with a slight fade out effect before the rest of the items move up to replace the gap.
