Actionscript 3 :: Flex Override Public Function Set Data
May 11, 2010
I have a datagrid with itemRenderer in datagridcolumn as my custom component(c1). I am getting the dataprovider data in custom component by overriding the set data function, it is fine. But now my custom component(c1) is also having another custom component(c2).
Now the doubt is - how to get the dataprovider data in c2 component?
If I override a public function in a base class, I would have thought that this override function is called and the original is ignored? though this doesn't seem to be the case...
public class AbstractScreen extends Sprite { public function AbstractScreen() {
[Code]....
If my model dispatches a CHANGED_LANGUAGE event, the text in the views gets updated, But I also get a trace of "WARNING: need to override public function updateLanguage()"
Is it possible to externally override a public function of a class (as opposed to override via inheritance)?
For example:
Code: Class Foo {public function doFoo():void {trace ("Foo"); } } Such that:
[Code]...
I know this is possible in JavaScript and ECMAScript, but the compiler won't let me get away with this kind of mischief in ActionScript, from what I've seen: It barfs up a 1168 Illegal Assignment error as soon as I attempt to assign a new function to doFoo.
I'm thinking specifically in terms of a "hot fix" solution where you deploy a small swf that replaces a specific chunk of code in a larger application, without the need to recompile/deploy the full application (or even see the sourcecode for that matter, just know the API).
I'm having some big issues with the scoping problems in my XMLConnect Class. I already found some things about the Delegate class online for setting the scope correctly, but my code still doesn't work the way it should Problem I need the XML data to be accesible in the public function Strip() because the user needs to put in some characters to strip from the strings in the xml file. Does someone known how to fix this scoping problems?
In flex charting you can customize the box which displays datatip information, but is there any easy way of changing the little circle which is displayed next to the datatip box?
http:[url].....
I've found the method positionDataTips() in ChartBase which appears to do the drawing of the circle. I was going to subclass LineChart and override the method with my modified version of it. However, this method needs access to a lot of private instance variables which are only accessible to ChartBase.
I trying here to avoid having to bind resources to all my components labels ( ie a button) and find a way to have this automated.
Problem: It corrupts the layout in design mode to bind directly in the mxml label="{resourceManager.getString('myResources', 'submit')}" and makes the design view useless. but when declaring bindings elsewhere, in actionScript or via a bind tag, it is counter productive and prone to many errors and miss.
Proposition: I would like to create my own button that automatically invoke resources to localize a button label. So the author puts "Submit" in the mxml description of my button, and when running it would take the value of the label ie "submit" and use resourceManager.getString('myResources', 'submit').
but I can't find the way to override the set label function, Is it possible if yes how? else how can I go about it?
Maybe I am missing an essential process here that would make the use of resources more elegant, as well as how to override such thing as a button's label.
I've a custom itemRenderer for my datagrid. To set the actual data I use the following method:
override public function set data(side:Object):void{ ... }
As soon as I use this function the cell doesn't show up any item Editor anymore. Why is that? When I remove this function the itemEditor is working but with the wrong initialization data.
I have been working on a Flex Mobile application using Flash Builder 4.6. I have 2 mxml 'views' in my project. In one mxml file, i have a function that grabs xml data. In my other mxml file, I have a refresh button that when depressed is suppsosed to call the function in the first mxml file in order to once again grab the xml data. I dont know how to call that function from outside the mxml file it is housed in. [UPDATE #2]* I thought I should share some more details about my issue.
It is a reddit client mobile app. It fetches the feeds, etc. In my main view called RedditReaderHomeView.mxml, I am using a splitViewNavigator spark component to house two other views like so:
I have got an open source "Organisation Chart" component in Flex from the below link [URL]..But the component is in Flex 3, and I want the same in Flex 4.When I am trying to run the same in Flex 4, I am getting some weird errors :
1024: Overriding a function that is not marked for override. OrgChart.as
Any one has any idea, Please help me with this.Also If any one knows any other "Org chart" component for Flex4, Please let me know.
I always have a question about override custom event. I am not sure why or what do to inside override function. I searched google but didn't get too many feedbacks. EDIT: My projects seem work fine even though I use my custom event without override. Anyone could explain it?
How do I call a custom component's public function from the main app. For example, I've got a timer component, MyTimer.In the main app, I want to call startTimer() or stopTimer().In the main app, I've got:
<visualcomponent:MyTimer /> In the component, I've got: public function startTimer():void {
is there a way to extend a function, or override it, without having to rewrite the whole function. e.g would it be possible to add a simple trace statement at the beginning/end of the addChild() function. im looking for something similar to super() in constructor. just as i dont have to rewrite the whole constructor of the class that i extend, but i can add my own code, then call super(). ive read something about prototypes and that they could be possible solutions.
I have learned that there is a class called Function which is used as a blueprint for all as3 functions. Is there a way to override the call() function within the function class so that a trace can be made when any/every function is called?
I'm trying to create a simple game where you can click on shapes in a toolbar and then drop them on the screen.There are three shapes, so I want the user to be able to select different shapes and such.I've written the code thus far like this:
Code: stop(); var cursor:MovieClip; var shape:MovieClip; var circ:MovieClip;[code]..........
I'm getting a duplicate function error and incompatible override error for both the "rect" and "pent" functions, but the code works fine if I eliminate these two functions and just include the "circle" function (albeit the old circle disappears the instant I drop a new one).
I have a .fla and one.as(DisablingButtons.as).The .fla currently has only one key frame and three movie clips.First movie clip has base class flash.display.MovieClip and class DisablingButtons.as.The other two movie clips have base class DisablingButtons and their own classes (set by flash on export). The movie clips have identical timelines, 20 frames, two motion tweens, and the only action is stop();on frames 1,5,10,15. I get two errors:5000: The class 'DisablingButtons' must subclass 'flash.display.MovieClip'and 4 copies of 1024: Overriding a function that is not marked for override (on frames 1,5,10,15 of movie clip #2)
I am importing flash.display.MovieClip and have public class DisablingButtons extends MovieClip.Code below...[code]..........
I have two child classes ClassA and ClassB both inherit the same base class.
I also have a function that has a parameter which could be an instance of either child classes.
function Test(instance):void //instance is either a ClassA or ClassB instance { instance.DoSomething(); }
However, when I run the test, it's always the BaseClass.DoSomething() get called. How can I use the same function (DoSomething()), but call child class function instead of the base class one?
Is there anyway that I can override a rollOut function if an action is performed?
I have three mouse events: a ROLL_OVER a ROLL_OUT a CLICK
Once the CLICK has taken place I want the movie clip to stop on the last frame. But because I have a ROLL_OUT Event it wants to continue to go back to that event when I roll out of the movie clip.
do I need an "if" statement here to override the rollOut function when I click?
I'm using this function function wait(mc, n) { mc.stop(); var myInterval = setInterval(function () { mc.play(); clearInterval(myInterval); }, 3 * 1000); } _root.wait(this, n)
To delay events along my timeline. That code works fine. My problem is that is that I also want the user to be able to pause the movie at any time. However, if the pause button I'm using is pressed by the user while the timeline is delayed using this function it starts playing again after the interval even if the pause button is still pressed. How can I override this wait function with a pause button?
i know its easy to override a function of a parent class, but I need to be able to override a function for a class on movieclip.. see highlighted code.
override a custom class method with a function expression? For instance, if I want to change the destination of a button on the fly, I could theoretically type:
Code: var new_destination:Function = function(evt:Event):void{ go_to_new_place();}; myButtonClass.mouse_clicked = new_destination;
but unfortunately that generates an error because the class method "mouse_clicked" is already defined in my class (with the eventListener tied to it). I tried using the "override" keyword in the Function Expression but that didn't work either.
I'm trying to override the addEventListener function to input an extra line of code to put the event listener type in an array so I can remove it all at once.But the override function doesn't seems to run.
Code: override public function addEventListener(type:String, listener:Function, useCapture:Boolean = false, priority:int = 0, useWeakReference:Boolean = true):void
