I'm having some troubles with the use of interface and inheritance in AS3. I've done lots of OOP in the past and what I'm trying to do seems obvious to me, but doesn't work in AS3. The question is : Is it possible to override a function that return an Object of class A, and make it return an Object of Class B which extends A ? It seems not to be possible, since I'm getting a signature error in Flash, when compiling. For example, the following set of class do not compile (the code in function definition doesn't matter):

how i can to know if the value of a FlashVar (in as3) has changed. For example: if i inicialize the flashVar with "1" and after set the flashVar to "0", everyOne knows that this flashVar has changed. the problem is if i have the FlashVar value setting in "2" and i set the flashvar value to "2", again.
There are any way to know if this flashVars has changed his value for the same value?
I've a basic portfolio page with 5 links. The idea being that 4 stay small and the active page is a larger font. When one link is clicked, itself and whatever font is currently large both swoop down and then the large text is replaced by whatever section the user chose.
I haven't keyframed anything, it's all done with actionscript and here it is. I made one of the links show what the var is currently set to in a dynamic text box. That all seems right. But whenever the 'currentchoice' mc is asked the swoop down, it just disappears rather than animates out. Here's the actionscript.
import mx.transitions.Tween;
import mx.transitions.easing.*;
var currentchoice:Object = new Object();
currentchoice.selection = large_anne;

Is anyone aware of a clever way to query (in AS3) an .xml file so that when the .xml file changes (as the result of an Access query in this case) the AS3 application (Google Maps API) refreshes using the new .xml data?
View 3 RepliesI have an animated SWF that I created. It is supposed to be at 3FPS, however it runs at 24FPS which is my stage's current FPS. How do I have different FPS's for my stage, and my SWF?
View 1 RepliesI have this PHP that constantly changes an XML.
So... I'm asking, is there an eventlistener in flash that instantly detects change in XML?
What I do currently is to just load the XML again and again and check if something has changed. BUT it takes about half a second to load the XML again (not from cache).
I know I've read something about this here before but I can't find it, so for Mr. Thicky here, I have dragged some buttons on my stage - each one is actually an instance of the same movieclip. In the IDE, I have given them instance names like 'myButton1', 'myButton2' etc. I've then grouped all these buttons together into a single container movieclip called 'buttonHolder'. Now, in my code, I am trying to retrieve the instance name of the button I have clicked on:

I inherited a custom component from TextField. The component needs to know when any of its styles got changed at runtime via setStyle. How would I do that? It's probably obvious but I couldn't find an event or appropriate method to override.
View 2 RepliesCheck bottom of this post. I am using MVC and the problem concerns my model. With my code I am creating a board which in turn creates tiles. Every tile on the board gets an X and a Y value. After this I want to prevent access to the setter to prevent myself from accidentally changing the value ever again.
I was thinking of using a constant instead of a variable, but it seems I have to define the value at the time of creation. In other words: const myConst:uint; myConst = 2; // does not work
Right now I have a work-around which I am not happy with. Surely there's a cleaner way.

I'm implementing some kind of combobox control (by extending spark.components.supportClasses.DropDownListBase)
Now, inside this control; I need to know:
If the dataprovider is changed/assigned. (which I can do... the first approach below works); if any item in the dataprovider collection has changed.
I tried 2 methods that did not do the trick...
1ST APPROACH:
2ND APPROACH:
UPDATE: Edited above.. The first approach lets me know if the dataprovider is changed but not if any item is updated in the dataprovider collection. The second approach does not work at all..
I'm having some setbacks in self-learning this language and Flex Builder. Right now I'm trying to make a very simple implementation where a label effectively has its text added to multiple times over the first few seconds that the program is run. The problem I'm running into is that I can't just put all that into one function + one call on that function, as changes to the label's text are apparently not seen until that function runs its full course.So I tried using a viewstack and cloning the canvas a few times, giving each canvas's version of that label a different bit of text. Then I set the initialize function for the viewstack to change the canvases on regular intervals over the first few seconds. But that didn't work either, as the difference isn't seen until the function runs its full course.So then I tried putting function calls on the individual canvases' initialize attributes, and those functions aren't being called at all apparently.I know this probably isn't even the way that you're supposed to animate something in ActionScript or Flex, but I still would like to know how to approach the problem this way for future reference.

I have a dynamic TextField that has the word "DEVICE" filled in in the flash IDE. If I compile and run, it works fine and I see the word correctly.
The problem is if I change the text at runtime. Depending on the word, it doesnt show up correctly, if I change the word to "CARD" I see it just fine, but if I change it back to "DEVICE" then it shows up as "DECE". It won't show the "V" and the "I"... I can't figure this one out since it works if I set it to "DEVICE" in the IDE, but doesn't work if I dynamically change it to "DEVICE"
I'm working with a rectangle I used code to generate
hpBar.graphics.beginFill(0xFF0000);
hpBar.graphics.drawRect(40, 40, 90, 22);
hpBar.graphics.endFill();
addChild(hpBar);
The rectangle itself works fine without any problems, but when I try to change the width of the rectangle, it's x value decreases slightly, but I'm not sure why it does this. (90 is the original width, hpPerc is another value that will for my uses always be between 0 and 1).
hpBar.width = 90* hpPerc;
Unfortunately, as I stated, changing this shape's width seems to change the x value as well, which really doesn't work at all.
Say I have a webpage where a user enters their name and it is displayed to them on a swf. If I have a save button, how could they save their dynamically changed swf to their computer, with their name on it?
Bare in mind that if a normal save is completed, they will only be saving the swf on my server. Somehow, something needs to happen to get them to save the swf with thei name on it, as saving a dynamic swf is not possible in as3 (I dont think)
I'm a complete newbie to Flash and programming, so please forgive my lack of knowledge! I have been trying for a good couple of hours now to do what I'd think would be a simple task - change scene when the value in a comboBox is changed.This is the code I have:
stop();
dropdown.addEventListener(Event.CHANGE, changemade);
function changemade(event:Event):void {

I have a project in which i need to pop up an alert to the user before a combobox value is changed. This feature is to allow the user to stay in current state if modifications were not saved. Meaning that the user will be able to cancel the change. I have sub classed ComboBox and tried to hook on ITEM_CLICK of ComboBox.dropdown but this event is triggered after the value is changed. Also, I've tried MOUSE_CLICK ans MOUSE_DOWN but without success.
In my code, I have added a "preChange" event to my CustomComboBox. This event should be triggered before a change is made. Also, I've introduced a method called commitChange that will be called manually to actually commit the change.
In a DataGrid, how can I force data() of all itemRenderers on visible rows to be called when I've made an update to the dataProvider.I'n the following the Grid isn't updated after pressing doSomething.

I have an if/else statement which checks the length of my current title, and then is suppose to change the defaultTextFormat of the title textField and set the text. Currently the title will not show up now, no matter what character length the title is, any thoughts on what I could be doing wrong here?
public function switchTitle(sentText):void {
titleString = sentText;
trace("---------"+" ");
trace("Forumula testing");

I have a class Grid which produces a graph paper like grid on in the drawing area. I then have 5 other classes for different shapes to draw with; Line, Polygon, Ellipse, Curve, Arc Now, these 5 classes use an instance of Grid because Grid has a resolution and a scale. Inside Grid I have:
public function set resolution(x:Number):void {
_gap = (modBy10(x) / 10);
_scale = (modBy10(x) / (this.resolution * _scale));
[code]....
I'm just lost for a solution on how to update every instance of my 5 drawing classes when Grid is changed.For instance, Polygon is made up of multiple instances of Line, Line(length, angle) where "length" is in either in, ft, cm, or m. If the user wishes to change the scale from say 10ft per 100px resolution to 20ft per 80px.. Is there an easier way than re-drawing every Line inside Polygon?
I am developing an AIR application and I want to change my project theme to one of the additional included themes that is packaged with Flash Builder 4. So, I went to the Project Theme and changed it and it looks like it is supposed to in the Design View. When I run the application, the components (eg: a button) themselves look like it is supposed to, but the application's background is just white instead of the displayed color in the design view.
View 2 RepliesI have an editable grid and would like to update values based on the edited cell and I am doing this in the itemEditEndHandler such that when they finish editing a cell I update other cells that are dependent on it. the only problem is in the itemEditEndHandler the new value has not registered yet. If I try and get the value of the cell i find that its still giving me the old value and not the new value that I have entered.
View 2 RepliesI've succesfully loaded and parsed this XML file, using XMLParser and AS2:
<Resources>
<item author="Julian" date="28/12/2010" time="01:18" id="876" like="8" dislike="5">
<Text>Sample paragraph</Text>
</item>
[code].....
Now, what I need, is to increase and store the "like" and "dislike" values with the click of a button, but I don't know how to modify and store them in the existing nodes (eg., without adding new ones).Do I need to use PHP, or can AS2 handle it by itself?
Anyways, there is a property that changes occasionally to reflect the name of a level in a game (object._I._M.text). It could take a minute to change, or a max of two minutes, depending on how fast all players are able to finish the level.
I want to be able to listen for the change in this property to fire off another function. I have found very few answers to this online, and the examples I have found were very incomplete and poorly written.
I have tried ...
theobject._I._M.addEventListener(Event.CHANGE, myfunction);
I have a weird problem with verticalScrollPosition in Flex.I have a content Canvas and a wrapper Canvas. The content is large (5000px X 5000px), the wrapper is 800px X 800px.
public var wrapper:Canvas = new Canvas();
public var content:Canvas = new Canvas();
wrapper.addChild(content);
application.addChild(wrapper);
I would like to set the wrapper's scrollbar position dynamically anytime. I can do it by calling its properties:
wrapper.verticalScrollPosition = A;
wrapper.horizontalScrollPosition = B;
This is working fine. But! If I set a default scrollbar position when the Canvas is complete:
wrapper.addEventListener(FlexEvent.CREATION_COMPLETE, function(e:FlexEvent):void{
wrapper.verticalScrollPosition = DEFAULT_A;
wrapper.horizontalScrollPosition = DEFAULT_B;
});
I can't set the verticalScrollPosition anymore:
wrapper.verticalScrollPosition = C;
trace(wrapper.verticalScrollPosition); // Outputs: DEFAULT_A
So the problem only exist if I set a default position using 'FlexEvent.CREATION_COMPLETE'.
I have an image which its source depends on a bindable property of another object.I'd like to know when this source changes, for example, by capturing the bind event or another related event of the Image control.
