Flex :: Creating Dynamic Object - Generic Component
Mar 27, 2012
I want to create a generic component in flex. This component deals with different ArrayCollections dynamically (I want it in that way). So I thought to pass the arrayCollection and the type of that arrayCollection as arguments to the component.
Like,
var list:ArrayCollection<ClassA>;
init_Comp(list, "ClassA");
If it is possible, I can read it like this,
var newDynamicInstatnce: typeOf("ClassA") = list.getItemAt(0) as typeOf("ClassA");
Finally I have a Dynamic Instance type of that I pass. Is this possible in Flex or Is there a better way?

Does there exist a Flex view component that you could just pass it a custom object with all public fields/properties that it could reflect over and produce a basic UI view using flex components. Is it possible to use something like the Spark DataGrid with one item laid out vertically. It would only have to support:

I have this bit of code, and it's not working as I expected. btnContainer is a VBox that contains a ton of buttons (toggle=true); and I want to reset them to un-toggled at a certain point.
for (var btn:Object in btnContainer.getChildren()){
if (btn.isPrototypeOf(mx.controls.Button)){
btn.selected = false;
}
}
With the above code, "btn" shows up as just the index during each iteration of the loop (0,1,2,3,...), and the conditional never evaluates to true.I also tried this:
for (var btn:Button in btnContainer.getChildren()){
btn.selected = false;
}
This works fine, except that there is also a label inside btnContainer; so it throws an error when trying to cast the label as a button.

I'm creating a new Color object in CS5. Essentially I'm using a component slider and linking the value to 360 hue and converting that value to color hex to pass into a color object which will be assigned to an object (in this text case a standard square movieclip). However, when compiling I keep getting the error 1067: Implicit coercion of a value of type flash.display:MovieClip to an unrelated type Number.

want to simplify coding and wondered if there was a way to write a script that could be used on multiple objects without having to write it to address each object individually. I am building a simple menu where I want the menu link to rise and scale up when the button for it is rolled over and then return to its original position when the mouse rolls off. I know I can write this per button and per item, but wanted to see if there was a way to write it once and then apply the action to everything. EX. My menu consists of 5 items (and respective buttons) home_mc (home_btn), menu_mc, dining_mc, contact_mc, specials_mc.If I write the code
home_btn.addEventListener(MouseEvent.MOUSE_OVER, homeOver);
home_btn.addEventListener(MouseEvent.MOUSE_OUT, homeOff);
function homeOver(MouseEvent) {

My requirement/need is the AS3 code for placing any type of Component(viz., Button, CheckBox, ComboBox, ListBox, radiobutton, Slider, Scrollbar,Label,TextField, etc.,) on the stage with desired width,height, X and Y parameters(values) which we mention in "Properties" tab of Properties Window in flash. Hence, What i need is, (say)a generic ActionScript 3.0 method/function, which places any of the components present in "Components Panel" onto the stage. the function prototype or signature may be like this:
function addComponent(int <width>, int <height>, int <XPos>, int <YPos>)
t is a general query i think so. i.e., A basic programmer's task for defining a function for my requirement.I think,if I want to add a Button onto the stage at 100,100 pixel position and the button component's width and height are 50,50 respectively, (i.e., button.X=button.Y=100 && button.width=button.height=50).So, a button must be placed at 100,100, then, the sample code looks like this:
Button <btn_instance> = new Button(); //creates Button instance
<btn_instance>.addComponent(50,50,100,100);// properties of button.

I am simultaneously creating an object and adding it to an array, perhaps ill-advisedly. The following code worked on the main timeline, but not when I moved it to the constructor of a document class:
{
package {
import flash.geom.Point;[code]......
The following error is generated: ReferenceError: Error #1056: Cannot create property xx0 on IconTour. at IconTour()
I guess this is because xx0 isn't declared? How does one declare a dynamic object/variable?

Is there a way out there to essentially loop through a generic object to find out what parameters/properties are being used and/or what there names are?
ActionScript Code:
var obj:Object = new Object();
obj.foo = "hello";
obj.bar = "world";
//... and on for however many params you need
[Code] .....
I might be trying to do something that is essentially not possible, but I'm just thinking it would be very nice sometimes to access different parts of an object without having to directly know what the param name is...

I'm trying to extend the mx:Box container so that two buttons sit on the outside of the container to cycle through it's contents (similar to a scrollbar).
I've made a custom component that looks basically
like "mx:HBox->mx:Button mx:Box mx:Button" where the buttons and box are children of the hbox.
How do I offer the user access to the box (say its dataProvider and itemRenderer) through my custom component?
So they just need to write 'local:MyCustomComponent dataProvider="rar" itemRenderer="rar"/>' and my box inside that component can use it?

Right now I'm working on an advanced hitTesting engine, and What I'm trying to do here is create an engine that will detect collision with one object instead of two. That basically means that if any other objects touch this movie clip, the hitTest will return True. Right now the .fla containing the engine has nothing but a circle that can be moved using arrow keys and 8 squares that disappear when touched by the circle. Obviously, I could do something like:
if (circle.hitTest(square1)) {
do so and so
} else if (circle.hitTest(square2)) {
do this and that
} etc...
But that would be too long, since the engine has to be able to contain 100 squares without too much change in the code.

I need a List that resizes to exactly fit its content, unless that height exceeds its (dynamically sized) parent container. My requirements are as follows:
The component extends List, or at least acts similarly. variableRowHeight and wordWrap both equal to true. The height of the list cannot be less than minHeight (roughly 32px for scrollbar arrows). The height of the list cannot be greater than the height of the parent container .
Note that the parent container can be resized dynamically.
The height of the list should be updated as the size of both the contents and parent container changes.
Live updating would be preferable but not necessary.
There should be no scrollbars if the content height is less than the parent container height (sounds obvious, but I've had trouble with this too).
The trouble is that with variableRowHeight and wordWrap, it's very hard to know the size of the content at any given time. If the parent container's width is reduced, a line wrap may occur in the list which will change the height of the content. I know I can measure the height of the list content using measureHeightOfItems() + viewMetrics.top + viewMetrics.bottom, but when should I calculate that? What events should I listen for? And the thing I've had the most trouble with - when should I calculate it to set the size initially (i.e. just as the content has finished populating)?

I want to handle multiple operations on a UI Component (button ,textfield, swfs,custom objects etc) in like scaling,skewing ,color,rotations etc etc and save them too. Earlier the actions were done
using a single tool and single mxml file but now the tool is separated into different tools. Was wondering how i can design / use something like Toolmanager class to handle actions etc?
Also the tricky part is that some objects can have more operations defined for them Like 'object1' has 3 operations that can be performed on it and 'object2' has 5 operations defined on it.
We are using MVC design pattern but no frameworks as such. What are the different design patterns that can be used to do this? Edit: To be more precise i want implement this in AS3 OO way.The application is similar to drawing application which supports addition of various images,text,audio,swfs etc. One added user can perform various operations of the objects..like adding color,scaling skewing,rotation etc etc and custom effects and after that export the drawing as PNG.Likewise some effects that are applicable to text are not applicable to images and vice versa. and some effects can be common.

I have a custom ActionScript component that I'm using in a Flex application (Flex 3.3, ActionScript 3). This component contains an Image control whose visibility is set dynamically based on a property of the data element provided to the component. The problem is that even when I set the image to be visible, it will not render onscreen. Is there something specific I need to do in order for the image to render? Snippets of relevant code below:
override public function set data( value:Object ):void {
_data = value;
if( _data ) {
if( _myImg ) {
_myImg.source = someImageClass;

I am trying to:
1) create a dynamic property
2) bind that property to a label
This works great for "sealed properties", but for dynamic properties there doesn't appear to be any event triggered. Are dynamic properties implicityly not bindable?
var myObj:MyType = new MyType(); // MyType is dynamic
myObj["myDynamicPropertyName"] = "initialized";
BindingUtils.bindProperty(myLabel, "data", myObj, repeatedLabel.name);
// myLabel now displays "initialized"
myObj["myDynamicPropertyName"] = "changed";
// myLabel still displays "initialized", it should say "changed" !!!

Is there any way, without having the creator of the object implement any special functions (no specific serialization functions) (however, they can use annotations), to have Flash serialize a generic, possibly deep (objects within objects within objects, etc, etc, etc) object?
