ActionScript 3.0 :: Extend SimpleButton Class To Set TextField?
Jan 7, 2010
I was hoping to extend the simple button class in order to have it contain a text field that I can set with code but still have the benefits of the up/over/ states etc... (To set a textfield within a SimpleButton doesn't seem possible with SimpleButton out of the box, you cant reference anything in it).
I've been trying to change the text within a SimpleButton instance using this:
var drawButton:SimpleButton = main.drawButton; var upButton:DisplayObjectContainer = drawButton.upState as DisplayObjectContainer; var upButtonText:TextField = upButton.getChildAt(1) as TextField;
I just spent three hours on trying to understand basic positioning of TextFields and SimpleButtons...
I have a movieclip with a dynamic TextField and a SimpleButton inside. The TextField is NOT inside the SimpleButton (because then I can't change the text dynamically).
I want the TextField centered in the SimpleButton but when I set the Textfield.x it is displayed somewhere completely different than when I set the SimpleButton.x to the same value. Regardless of if I do i programmatically or not.
I created a button (button symbol), inside this button symbol there is a vector shape which will change colours in mouse over and a dynamic text field. i want to use this button symbol in more than one locations in my stage. so i need to change the label of these instances (by changing dynamic text ). but i can't access the dynamic text in as3 using following code,
btnsample.txtbtnlabel.text = "button label"
this code is working fine for a movie clip symbol but not for a button symbol.
I have a dynamic textfield which updates from a textfile. The textfile grows constantly so I want the textfield to grow accordingly without having to update the .swf. I have added a component scrollbar to it, but since I don't have any text in the box before I load it, the scrollbar is disabled. What can I do?
If I have a Document class that extends MovieClip, and I want to use it as the basis for another Document class, is it possible to create a subclass that extends the main document class and use that for a different FLA?
For example,
fla1.fla has a document class of MyMainClass: public class MyMainClass extends MovieClip fla2.fla has a document class of MySubClass: public class MySubClass extends MyMainClass
I've tried, but now I'm getting errors that all of my variables that reference stage instances aren't being found.
I'm looking for a way to extend a TextField that's allready on the stage in Flash (AS3) something like this:
public class ChildTextField extends TextField { //code for childTextField comes here }
I've placed a TextField with instance name 'thetextfield' on the stage. Now I would like to tell flash this textfield is of type ChildTextField. So in my Document Class I declare that textfield as a ChildTextField:
Say you were importing flash.events.KeyboardEvent and you wanted it to extend the MovieClip class, is this possible? Where you dont have access to the class to just type "extends XXX"
Im following a 'recipe' in the O'reilly AS3 Cookbook, but it doesnt work.i keep getting the error 5000: The class 'RectangleButton' must subclass 'flash.display.MovieClip' since it is linked to a library symbol of that type.
I've created a button under the SimpleButton class named button1 in Flash CS4. I've set button1 so it exports to AS3. I keep getting an Error 1061 at line 3 of which I have no clue what I'm doing wrong:
Code: 1 import flash.events.MouseEvent; 2 3 button1.addEventListener(MouseEvent.MOUSE_OUT, link1); 4 5 function link1(MouseEvent) 6 { 7var one:URLRequest = new URLRequest("[URL)"); 8navigateToURL(one, "_self"); 9 } Error 1061: call to a possibly undefined method addEventListener through a reference with static type Class.
I am trying to set a SimpleButton called tackle in my Pokemon game to a variable called ability1. Im getting the tackle var from a pokemon class, but its saying
TypeError: Error #1034: Type Coercion failed: cannot convert tackleAbility$ to flash.display.SimpleButton. at pokemonBattle/abilityList()
If I am not mistaken in order to dispatch a message from a class you need to extend EventDispatcher. What happens when you are already extended the class from a different class? Is there no way to dispatch messages?
I'm developing a Rails project that uses authlogic for authentication. And I have a part in that project that is realized with Flex, and I need to know how a user can be authenticated if he or she is logged in or not. I've set up a webservice called UserSessionService and I was trying to get the user who is logged in, but it doesn't work. If I try to get it with UserSession.find, I just get a # as the result (and therefore that's always true).
Here's the UserSessionService.rb:
require 'weborb/context' require 'rbconfig' class UserSessionService def login UserSession.find end end
I tried to extend the UserSessionService class from Authlogic::Session::Base, but that doesn't work either.
when I create my object uniform which is a simple object, I pass it to my UniformObjectProxy.getInstance() static method to get the instance of my objectProxy, ok so far so good.my problem is when I try to bind a property of my objectProxy instance like
the dispatchColorChange handler function is called only once an never again, I had check ChangeWatcher.isWatching() and return false meaning my objectProxy is not binding properly, if I create an objectProxy like
_opc = new ObjectProxy(_uniform); cw:ChangeWatcher = BindingUtils.bindSetter(dispatchColorChange, _opc, data.id);
the binds works just fine, so my thinking is the problem is when I extends the objectProxy class, how is the proper way to do this
My flex3 application downloads XML in e4x format from my web server, and and is left as a bindable XML object locally in my flex3 application. My visual objects then bind to various aspects of the XML object to display the data that I want.My simple program is getting more complicated, and I'd like to extend the XML object and add some functions to it, so I can keep the code that manipulates the XML object separate from my base application. Lets call this new object LoginXML.Can I please get an example of how to extend the XML object in flex3/as3 to create my own custom object with it's own functions. Part of my XML looks like
Ok, I have spent a little time searching and I can't seem to find an answer to my question, maybe I'm asking the wrong question. here's my situation:
I have a document class called Main.as, this class has variables that instantiate a CreateShape.as class that acts as a superclass. The CreateShape.as class has a protected function that is overridden by other classes (I have a CreateCircle, CreateSquare etc). Those CreateCircle etc classes, use extends to extend the CreateShape.as class, and thus have the ability to override the main method (called newShape()).
Just as a technicality, is there ANY object (or anything that can be placed inside of a variable) that does not extend Object?Even the "Class" object extends Object.On a similar note, what is the difference between these two?
[Code]...
I pretty much always use ":Object",but is there any situation where it would be better to use the latter?I also recently found out that there is a difference when using the "as":
I am working on inheritance for the first time. Here is the super class SetBlank.as
Code: import flash.text.*; class SetBlank { public var _textFieldName:TextField; public var _defaultName:String; public function SetBlank(textFieldName:TextField, defaultName:String) { [Code] .....
I can see the trace function working but the method which sets the text field to blank is now working.
Here is what I want to do...extend the String class Code: class example extends String {} and then I want to take things that are already strings and add a function to them which goes through and removes & and turns it back to & am things got some test code for that here
I need a way to "extend" or proxy the Number class in ActionScript.Basically I'll overload the toString method of it. But the Numbers should remain comparable with "<" and ">" operators.
I am considering using class extension as a way to connect my model with my controller. I tried looking on the internet but could not find any information on this topic. This led me to the question of when a class should be extended and for what reasons.
I've a strange issue. In Flash CS3 IDE, I linked a MovieClip to a SubSimba class. This class doesn't extend MovieClip (it has MovieClip package as its base) but, instead, it extends SuperSimba (that extends MovieClip). What happens? I instantiate SubSimba in my Flash project and it behaves as I if I called super() inside the SubSimba constructor: is there anyone here who understands why?
