How can I apply a TextFormat to a TextField instance in a super class?
Code:
// This doesn't seem to work:
var textFormat:TextFormat = new TextFormat();
textFormat.size = 24;
super.alertText.setTextFormat(textFormat);
Is it possible to call a method in the super class of a super class? I tried the above and it doesn't work, unsurprisingly. Only way I've been able to do it is to store a reference to a super.someMethod in the super Class (eg. var superMethod: Function = super.someMethod) and call that instead. Seems reasonable and it works but wonder if there is an in-built method for doing this?
View 6 RepliesI have very little experience with text in flash. In a dynamic text field I know I can apply a TextFormat to the entire field but can I apply different fromatting to individual workd in the field if for example I wanted to make a word or a few words of text a hyperlink within a textfield. Can I do that or would I need to use html text?
View 3 RepliesI am trying to create a spark datagrid item renderer. This item renderer extends a checkbox, and implements IGridItemRenderer public class CellCheckBoxItemRenderer extends CheckBox implements IGridItemRenderer
When I implement IGridItemRenderer, I need to implement the interface methods, I am having a problem with the following methods:

If I have three classes:
public class Example {
public function Example () {
}[code]............
You can see that the two last classes extend the first one, and both have the 'variable' property. In case that I have an instance of Example and I am sure it is also an ExtendedExample OR AnotherExtendedExample instance, is there some way to access the 'variable' property? Something like
function functionThatReceivesAnExtendedExample (ex:Example):void {
if(some condition that I may need) {
ex.func()
I'm not really asking how. What I'm asking is, is it possible? And I ask because I thought it was not - certainly it didn't work in AS2 - and yet that's what I appear to have done. Am I going crazy? Structure: A SWF (#1) with a class NewActivity that extends class AActivity. Another SWF (#2) with a shared library of code in it, including AActivity. A third SWF (#3) which loads the library followed by SWF#1. Here's what happened: I didn't expect AActivity to be able to be shared. I mean, it should be compiled no matter what in SWF#1, as SWF#1 includes a class that extends AActivity. I had added some properties to the AActivity class, ran the project, and when SWF#3 tried to set those properties I was told they couldn't be applied. "Of course", I said, "I need to recompile SWF#1, because the code is now out of date. The version of the class there doesn't include these new properties.".
However, that didn't work. I got the same problem. Maybe, I thought, there's a definition conflict between SWF#1 and the library, so I removed the AActivity class from the shared library in SWF#2 for the time being. Only SWF#1 uses it, and it should already be compiled into SWF#1 as, like I said, it is extended by another class there. But when I ran the project, I was then told that the AActivity class could not be found at all! Looking at SWF#1 in a decompiler, there is in fact no mention of AActivity (I had up to this point assumed it was implied). So this left just one option: I needed to recompile the library in the first place, not SWF#1. I added AActivity back to the library, recompiled, and it worked.
To check I wasn't going crazy: I added a test property to the AActivity class and recompiled the library. The containing project - SWF#3 - then set this property on SWF#1, which had NOT been recompiled, and then read it back out. No errors. I should point out that the getting/setting of this property is done through an IActivity interface - AActivity is not being accidentally compiled into the main project (SWF#3), and the decompiler indicates this also. Am I going nuts? I really didn't think having a runtime shared super class was possible in any way. If it is, that opens up a whole new world of awesome, even though I've created this project on the basis of that being impossible.
i have recently started a project that would require writing a set of classes and a small API.i know some basics of inheritance and extending classes but i still have some questions.
1) how should sub-class refer/communicate with super class.i think that dispatching events is the way to go but i have no experience on that. i have previously done it by having a parent set up a reference to itself in a subclass e.g
ParentClass.addChild(SubClass);
SubClass.myParent = ParentClass;
//i know that there is already a "parent" keyword in flash objects if i extend one but is that a decent way to communicate with super class
e.g SubClass.myParent.removeChild(this);//sounds a bad call
//but is it better if i dispatched an event that calls the removeChild() in the parent.i have is about dispatching events in a class that is likely going to be extended.
ActionScript Code:
public class Button
{
//add event listeners[code]....
//now if i extend the Button class into another class, let say ControllerButton and want that button to dispatch different event. e.g ControllerEvent, i am forced to override and rewrite all the common stuff in the handler functions.how to avoid having to override allot of common stuff.
the example of my problem is:
I have 2 textFiled there are:
1. myTextFied ( to store the original text )
2. displayText ( to show some line of original text )
I try this:
myTextField.htmlText = '<B>THIS IS A TEXT LINE 1</B>
' +
'<I>THIS IS A TEXT LINE 2</I>
' +

I have a problem where i want to remove the last character from a textfield (including linebreaks) that has multiple textformats without removing the formats.[code]...
i guess this doesn't remove linebreaks, and is very slow, seems to destroy my textformats.
or:
textfield.text = textfield.text.slice(0,-1);
this is faster but removes all textformats as well.
I'm trying to put some leading on a body of text, however it doesn't seem to work after a stylesheet has been applied. Without the stylesheet it works..
Here's what im doing:
ActionScript Code:
//CSS
cssStyle = function(my_txt){

I'm trying to apply a format (specifically, green-colored text) to specific words in a TextField. I tried the below method, checking for words in an array "commands", and it works fine apart from a few issues below (see pic).

function formatGreen(msg:TextField):void {
for (var i in commands) {

I have a set of 5 TextFields that a user enters info into. Each has the same TextFormat applied. If the focus is set by clicking with the mouse, the TextFormat is applied and all is well. If the focus is set by tabbing, the TextFormat is not applied and a default style for the font is seen. Here's my code:
Code:
var input1:TextField = new TextField();
addChild(input1)[code]...................
here is the code:
// Create new textFormat object-----
var myTF:TextFormat = new TextFormat();
myTF.font = "Verdana";
[Code].....
how do I address only the texField named t3 ?
Is there a way to prevent Flash from removing the applied textFormat style whenever a textField.text value is redefined?

throught code i am trying to read GUI display objects. (don't ask why) My problem is that i can read individual properties of TextField object and TextFormat object, but not traverse those objects to gather all its contents at once.
See my code, individual traces are hapening ok, but those in for cicles are not, i don't get it.

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.)

I have the following scenario:i have a MovieClip and I created a linkage for it named A.

what is allowed? how can I resolve the issue ? update ok this is an exact scenario but a more simple one that I still wasn't able to resolve. The original scenario is that I have a MovieClip called user_bg_me that has a linkage named user_bg_me that extends user_bg_genericthat extends 'MovieClip` inside user_bg_generic class i want to be able to modify elements inside the movie clip itself. using super.element_name provides an error that the property isn't found.

I dont know if that is normal, but this code create an infinite loop, because when i create a new instance of class Two, because of the extends, the class One constructor is called again, and creating a new instance of class Two, and so on...I know how can i get this fixed, but, what i want to know is, this is correct? Its a Flash bug? Isnt that way in AS3?
I am trying to extend the new AutoComplete component from Adobe. In two different places I need to bypass the AutoComplete methods and get right at the ComboBox methods.
I was told that super.super.someMethod() works just like it does in Java. But I keep getting Compiler errors:1084: Syntax error: expecting identifier before super.Any suggestions other than just cutting and pasting the code and extending the AutoComplete superClass?
Say i have these two classes:
MAIN.as
package
{
import flash.display.*; import mx.core.*;
import flash.events.*; import mx.collections.*;

Now how is it that I can add the variable SPRITE which is a Sprite in the OBJECT_square class to the display list of MAIN class? I've tried addChild(SPRITE) and super.addChild(SPRITE). If everything works I should see a red square somewhere on the screen but right now its all blank, except for the text drawn in the MAIN class.
Basically I want it so i can just make a new OBJECT_square and it will draw itself without any more instructions from the MAIN class.
In Flex, lets say I have a super-class... something like:
class SuperComponent extends DragStack {
private var _childReference:UIComponent;
public function SuperComponent() {
// ???
addEventListener(FlexEvent.CREATION_COMPLETE, onCreationComplete);
} private function onCreationComplete(e:FlexEvent):void {
//The 'this[]' technique doesn't seem to work and causes run-time errors:
//trace("Component found: " + this["myButton"]);
}}
And then I make use of the following derived-class in my application (just a mockup MXML as an example):
<!-- Component ChildComponent.mxml -->
<mx:SuperComponent>
<mx:Button id="myButton" label="Press Me!" />
</mx:SuperComponent>
How do I go about verifying the presence of "myButton" from the SuperComponent class, and referencing it? Do I need to use getChildByName( ... ) ?
I always don't call super() when I extends Sprite.But doesn't not calling super() cause any problem?Till now, I don't have any problem and I have never seen code which call super() in constructor which class extends Sprite.

View 3 RepliesLets say I have the following inheritance hierarchy:
Code:
Select allpackage {
public class ClassA {
protected function foo():void {
// do something
}}} package {
public class ClassB extends ClassA {

Now this is all well and good, as the call to ClassC.foo() will propogate through the inheritance chain; C > B > A. But what if I want ClassC.foo() to call foo() that is in ClassA and bypass the method call in ClassB? I have tried the following:
* Cast the method to the super-class type I want to execute, but this does not work as intended.
Code: Select all...
override protected function foo():void {
// do something related to Class C
// call ClassA.foo
ClassA(this).foo();
}

Whenever I call a class function that alters the TextFormat object (formatText,sizeText,colorText), the next time that one of these functions is called on a different instance the common formatting is applied. I've read that you need to redefine objects or arrays within the class constructor in order to make them unique to instances. I think I've done here with this code but it is not working:
