I am implementing a scrollbar using a custom embedded image using my CSS stylesheet. This is a very simple, thin scrollbar. I would like to configure this scrollbar using CSS properties at runtime, but so far I have been unable to do so. I know it can be done because I've seen examples of it in the net, but no code to review.
View 1 RepliesSo I have a movie clip associated with an external class in the linkage dialog. I put that movie clip on the stage. I have another external class that contains some code (not for the movie clip but for the stage). When I access the custom properties of the class in the actual flash file (not the external code) everything works fine.For example.myMovieClip.explodeTheCode = true;works in the main movie. However, it doesn't work in the external flash file when I have a reference to that movie clip.myRefToCustomMovieclip.explodeTheCode = true fails!It throws an error. In java, I'd just import the custom class the movie clip is linked to and then I can call all the extra custom methods on the movie clip in the external class I want. However, this does nothing. I still can't access any properties.So my question is, how do I access the custom features of a movie clip (that is linked to a custom class) from an external code file. It works in the movie, but not in the external source code.

In AS2 we can not add methods n properties to built-in classes in the way we do in AS1. Like we would -say- write the custom "isNatural" method on the "Math" class as follows : * The following code is valid in AS1 but not in AS2
[Code]...
As the "Math class" is static internally. We know why we can not add custom methods n properties to every class, as the way we do in AS1. Later I came up with senocular' s very nice tutorial on OOP in AS2. And now i know how we can do it in AS2 style in an efficient n organised way. But i have a problem with the following code. It should not work ! but it does... * Following code is valid for both in AS1 and AS2.

I am very new to AS3, and I'm confused about how things that would have been simple in AS2 are so complex and tricky now. For example, I want to create a bunch TextField objects that, for some reason, rise up every frame (as in : object.y-=1; ).However, I also need each TextField to reference the TextField that was created just before it.
I tried creating a variable that would hold such a reference : ThisTextField.Ref=LastTextField; but - this returns an "Access of possibly undefined property..." error. It seems I can only have custom properties on mere Objects ! This is annoying because an Object doesn't seem to accept event listeners (remember, I need them to do something every frame). Is there a way to simply set custom properties on my TextFields, without having to use custom packages ? Or is there a way to use event listeners on Objects ? I've read something about strict mode which could allow setting properties on other objects - what are the risks of turning it off ?
This is my first time working with a class attached to a movieclip that is nested inside a class attached to a movie clip.I've tested all the properties and methods of PTListItem.as and they work properly but when I try to call them on the list item through PTListTop.as it returns undefined.The end goal is to dynamically load a checklist via a txt file.

I am looking to change the background color of a input textField when the user selects that testfield to start populating it. I have done a bunch of searching and I keep coming up with this type of answer...
Code:
myTextField.onSetFocus = Set(evt:Event){
// Change color
}
Problems...
1) Is onSetFocus/onKillFocus still available? From what I can tell it is not.
2) I have my text objects encapsulasted in a class so I do not believe I am able to do it like I have been suggested.
I have a TextField that is formatted with bold and blue. However, when I change TextField.text, the formatting of the textfield resets and I have to setTextFormat again. This is the code I use to set my TextField. myText is the variable for my TextField. (This is just part of my code; it is part of a function for my EventListener.)
View 3 RepliesI am new to AS3, as well as Flash in general, so forgive me if this seems highly elementary. All I am trying to do is create a custom class that extends the MovieClip class and contains a custom property of "marker".

I'm just now learning the new object oriented way of scripting. It's been a wild ride, but I've finally learned how to keep script off my frames (very hard coming from as2).Here's my problem:
I have a TextField on the stage in my main .fla file named loadPercent.
I'm loading a jpg with preLoad.as and displaying the bytes loaded in loadPercent.
I can access my loadPercent TextField from my MainClass
but I can't access it from preLoad.as
the document class is MainClass.as
Code:
package
{
import flash.display.MovieClip;[code]....
I get three '#1120 access of undefined propery' errors for each time i try to access loadPercent.
a few basic questions: 1. all my files are in a folder in my documents, not in the flash directory, is this bad? I've seen people using com.whatever etc.
2. my main .fla file does not share the same name as my MainClass.as (it's not named MainClass.fla) Is that a problem?
I'm assuming these are inconsequential because my code seems to work up to a certain point.
I have a document class called Main.as In the class constructor I have the following listener:
enter code here
var listeningFORModeChangeToStudent:Sprite = new Sprite;
listeningFORModeChangeToStudent.addEventListener(TellAllModeChangeToStudent.STUDENT,exp);
addChild(listeningFORModeChangeToStudent);
[code]....
In a third class I make a call to the despatcher in the previous class:
enter code here
var ThisTellAllModeChangeToStudent:TellAllModeChangeToStudent = new TellAllModeChangeToStudent;
ThisTellAllModeChangeToStudent.tellAllModeChangeToStudent();
I have trace statements in eveything and from this I know the despatcher in TellAllModeChangeToStudent is being called.The problem is that the listener in the main.as is not calling the function exp.I cant see why and I dont know how to check if the listener is actually seeing the dispatch event?
I have a custom class being constructed from my main class. In the custom class it has another custom class that is passed in as a parameter. I would like to strictly type the parameter variable but when I do, 'the type is not a compile type constant etc'.This, I understand, is because the custom class used as a parameter has not yet been constructed.It all works when I use the variable type ( * ) to type the parameter.I suspect this is a design flaw, in that I am using an incorrect design pattern.It is actually hand-me-down code, having received a large project from someone else who is not entirely familiar with oop concepts and design patterns.
I have considered using a dummy constructor for the parametered class in my main class but the passed in class also takes a custom class (itself with a parametered constructor). I am considering using ... (rest) so that the custom classes' parameters are optional.Is there any other way to control the order of construction of classes? Would the rest variables work?edit)in main.as within the constructor or another function
var parameter1:customclass2;
customclass1(parameter1);
in customclass1 constructor:

I understand it's probably best practice to name your custom classes differently than the built-in AS3.0 classes; however, what kind of problems could I run into if I don't?Specifically, I have a class which, ideally I want to name DataProvider. But, as you know, there is already a DataProvider class on the Flash platform (used for list-based components and such).Now, I don't think I'll ever use BOTH of those classes, so I'm assuming as long as I reference the correct DataProvider class in my import statements I should be ok?What if I DO need to use both, is that even possible?

View 9 RepliesI have a movieclip simply animated with motion tween. On each keyframe, I made sure to name it introPhoto_mc.Now, before the movieclip first appears, I would like to change its content (just a picture change, dynamically loaded with loadMovie).

View 4 RepliesI created a movie clip which loops some text, i would like to populate the stage with instances of it but also with some in a different colour. When I copy frames from my clip and paste them into a new symbol(movie clip) the colour of the other instances changes as well.
View 1 RepliesFor the first stage, I was able to build a walk-through demo in flash pro by creating buttons that when clicked caused the flash to change to different frames. easy enough. Now for the final part of this project, I need to make the interface fully interactive, as I was trying before. ie: you can click any button and lights go on and off or a loop counter increments, etc. Since there is logic involved and too many permutations to do a frame for each possible state, I'm back to trying to do this in an object oriented way. I've got some test code here.

debugger has some errors, so i don't know what exactly it will do. the errors are at the last two if statements where i'm trying to change the object property setting of the label. there is another error at the last curly bracket.
the idea is that there are two labels and a button. the first label starts out visible. when the button is clicked, a counter is checked, and incremented, then the counter is again checked and the appropriate label has it's visible property set to true. the intent is that in a list of several labels, pressing the button scrolls down them, until you press while on the last, which resets the counter and the first label becomes the visible one.
