Actionscript 3 :: Add An Event Listener To A Button Inside A Tab Navigator (flex 4.5)?
Nov 4, 2011
I have a tab navigator defined in MXML, with two tabs.In each tab, I have some buttons. I have used ActionScript to add event listeners to all the buttons, and they work for the buttons that are visible (and in the currently "active" tab) when I load my Flex 4.5 AIR application.However, I get an AIR error for the event listeners attached to the buttons in the second tab.Here's the crucial part of the error:TypeError: Error #1009: Cannot access a property or method of a null object reference.

I want to add an event listener to each component inside a repeater, but don't know how. Here's some code I have tried:
<mx:Repeater id="rp" dataProvider="{dataProvider}" width="100%">
<mx:Button id="attach" creationComplete="addListeners(attach[rp.currentIndex])"/>
</mx:Repeater>
This doesn't work. creationComplete is not called until the repeater has finished instead of (as I expected) when the creation of the button is complete. I'm not sure how to accomplish this.
BTW - I also tried placing the creationComplete on the parent component to the repeater, but it would only be called the first time the component was rendered (the data inside the repeater sometimes changes) so that didn't work.

I I have a view in Flex 3 where I use a tab navigator and a number of views inside the tab navigator. I need to be know which view was clicked because of it's one specific view then I need to take action, i.e. if view with id "secondTab" is clicked then do something.
I have set it up to be notified, my problem is that I need to be able to know what view it is. Calling tab.GetChildByName or a similar method seems to only get me back a TabSkin object.
<?xml version="1.0" encoding="utf-8"?>

make the nearest button to the clicked text input default. For this purpose, I wrote the below code.
why is my buttonSwitcher function following behind the MouseEvent.CLICK?
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="addListeners()">

My stage has about 25 buttons on it. Each button when pressed to tweens the background to some random x/y coordinates and then loads an external swf file.This is all working, but the timing is off. How can I wait for the initial background tween to end before I make the loader call to the .swf file.Currently each button's behavior is called on the MouseEvent.CLICK event which calls a function that knows its unique filename.swf. I know you can add the MOTION_FINISH even to the tween event but then I would have to call a new function and lose track of the button that initially called it.

I have a flex application mxml file with 3 tabs.the first tab having the link button to select the value in the 3rd tab. Suppose, i have a link button in first atab. And the 3rd tab contains the combobox with values:"basic", "advanced". by default the vaule is displaying "default". When i select the linkbutton on the first tab, the "advanced"should be displayed in the comboBox on the 3rd tab. and the problem is , when click on the first tab link button , at that time the 3rd tab is not initialized. So it is not displaying the "advanced" in the comboBox. selecting the 2nd time on the link button it is displaying fine. But not first time. code: thirdTab.comboBoxId.selectedItem.data = 1;

I'm trying to add an event listener inside an object but it doesn't seem to work. other OO languages it makes sense for an object to be able to attach events etc itself rather than have some external action do it.Here's an example of what I'm trying to do:
ActionScript Code:
package {
import flash.display.MovieClip;
public class Player extends MovieClip {
[CODE]....
This gives an error "1120: Access of undefined property MouseEvent." suggesting that I don't have access to MouseEvent from within the instansiated object.What I can do is create an instance of the class from the Document Class for example and then do the following:
ActionScript Code:
newInstance.addEventListener(MouseEvent.CLICK, newInstance.mouseClick);

The fastforward and rewind buttons on the FLV Playback components don't work like normal ones. If you've tried to use them you'll notice that they respond to a click event rather than a mouse_down event.
By taking apart one of the skins I've found that the fast forward movie clip is forward_mc.
How do I create an event listener for the buttons inside the FLV Playback Component?
If the instance of my FLV Playback component is called "movie," how do I access it? I've tried this, but it doesn't work:

I have created event listeners for a particular movieclip.Insidet this movieclip there is so many objects.When ever I click on the parent movieclip the event listener calls the function for the child object. I had tried removeEventLIstener()
import flash.display.MovieClip;
import flash.events.Event;
import flash.events.MouseEvent;
var info:MovieClip=new MovieClip();
info.graphics.beginFill(0x000000,0.35);

I'll keep this simple (I hope). There's a button with an event listener on a frame of the main timeline. You click the button to go to the next frame and a movie clip plays. The instance of that button doesn't exist on that next frame. Does the event listener for the button automatically get removed when you go to that frame since the button doesn't exist there?
The movie clip is set up to send the main timeline back to the previous frame when it's finished and my event listener seems to vanish when I go back to that frame.

I'm creating a minesweeper game as my first flash project, but I'm already stuck on something technical. I have created a button named Button which contains a bitmap. I have a lot of instances of that button on stage, and they are put there by actionscript using a for-loop. Their instance names are button0, button1, button2, button3, etc.
This is the code for the eventlistener: It's in the first keyframe of the actions layer.
var buttonListener:Object=new Object();
buttonListener.click=function(evt:Object):Void{
trace("clicked");
} for (i=0; i<rows*cols; i++) {
eval("button"+i).addEventListener("click", buttonListener);
}
I also noticed that when I do this for one button that I created myself and put on the stage manually, this also doesn't work, but when I pick one of the predefined buttons, it works just fine.

I have a set of buttons on, and what i would like to do is change the value of a variable, depending which button you are over.i know i could do this by writing an event listener and a function for each button, but this is too time consuming.I'm sure in the old days it would have been as simple as if btnwhatever.mousedown = true then.... but now i have no idea.

I would like to know if it is possible to pass a clip event on to both the function that has a listener, and to the button that is being pressed. I am finding the listener takes it and thus the button doesn't see it.I found a walk around, however, I'd like to know if it is possible say for one clip event to be seen by both objects?For example, with the mouse over a button the listener function detects the event and carries itself out, however, the button misses the event now.

Whenever I remove an event listener to a button then that button no longer works. Does it cause memory leaks to not remove these listeners.....come to think of it I have about 30 eventListeners that I cannot remove otherwise the application ceases to function correctly. Is my application a memory black hole? How should i proceed with garbage collection?

I have a situation where I'm calling a function with an event listener attached to a button, which in turn calls a function, which does a number things including calling a second function which resides in a child swf.
Just as an example:
Code:
myBtn.addEventListener(MouseEvent.CLICK, firstFunction);
function firstFunction(e:MouseEvent):void{
//I call another function in here (among other things)
externalSwf.stopTimer();
}
"StopTimer" resides in an external swf which for our purposes is called externalSwf and it resets a running timer.
Code:
function stopTimer():void{
myTimer.reset();
}
I'm getting argument mismatch errors, which often have to do with the Event Objects not matching. The event object for firstFunction is a mouse event triggered by a click so I put in e:MouseEvent...what I don't clearly understand is, what type of object event is dispatched when I call the function stopTimer from inside the function firstFunction?

On the main timeline, I have placed a movieclip (movieclipone) which contains some content. On frame 85 of movieclipone, there is a new keyframe which contains a movieclip that hasn't previously appeared in the movieclipone timeline, (moviecliptwo) which contains four buttons (btnone, et cetera).Is there a way to have code in the main timeline that attaches listeners to the buttons inside moviecliptwo, which, when pressed, trigger a function that increases a counter and tells movieclipone to go to the next frame? This is the code I am using right now:
stop();
movieclipone.addEventListener(Event.ENTER_FRAME, onEnter);function onEnter(e:Event):void [code]........
When I debug the movie, I get this error at frame 85:TypeError: Error #1009: Cannot access a property or method of a null object reference.

On my stage i have a Button with the instance name stopBtn, this is also exported to an actionscript class called classes.stopBtn (stopBtn.as in a folder called 'classes'). The button is on the first keyframe in the main timeline, in a layer with other buttons on that layer
