I have a problem with my StageText field not dispatching the keyboard events. StageText is implemented on an AS3 only project. Everything works fine except that when I hit the return key, nothing happens...
below follows my code:
_input = new StageText(new StageTextInitOptions(true));
_input.text = _trackerData.trackerComment;
_input.maxChars = Globals.TRACKER_INPUT_CHARS;
_input.fontFamily = "Antenna Regular";
_input.softKeyboardType = SoftKeyboardType.DEFAULT;
_input.returnKeyLabel = ReturnKeyLabel.DONE;
_input.autoCorrect = true;
_input.fontSize = ScreenUtils.cmToPt(.25);
_input.color = 0x000000;
_input.fontWeight = "normal";
_input.stage = this.stage;
_input.viewPort = new Rectangle( ScreenUtils.cmToPx(.35),
ScreenUtils.cmToPx(1.5),
stage.stageWidth - ScreenUtils.cmToPx(.7),
ScreenUtils.cmToPx(3)
);
_input.addEventListener(KeyboardEvent.KEY_UP, keyUpEventHandler);
private function keyUpEventHandler(evt:KeyboardEvent):void
{
trace("keyCode", evt.keyCode);
}
But the function is never getting called!
Anybody knows what the problem may be?
Thanks in advance!
I can't find why, but if you use the ReturnKeyLabel.DONE, it don't work! Try with another, like ReturnKeyLabel.GO
You need to add the event listener BEFORE setting the viewport property

I have this annoying issue that I hope someone might be able to help me with.
I have a mute button that I created and I have another movieclip inside of that button. All I want it to do is when I toggle the mute the movieclip inside will go to the according frame.
However, every time I try to call the movieclip inside of the button, this error comes up:
Access of possibly undefined property mcMuteToggle through a reference with static type flash.display:SimpleButton.
The instance name for the movieclip within is "mcMuteToggle".
Why not make movieClips that act like buttons?? Since I dont think actual button (simpleButton) types can deal with sub-MovieClips (especially if they too have code). Even if possible don't do it, I can predict a mess whereby Button does things it shouldn't do depending on what code you have in those MClips.
Try an alternate button method, just for a test... You didnt show any test code to work with so I will make assumptions..
1) Make a shape (rectangle?) and convert to MovieClip (or if all coded, then addchild shape to new MovieClip). Let's assume you called it mc_testBtn.
2) Make that MC clickable by coding mc_testBtn.buttonMode = true;
3) Add your mcMuteToggle inside the mc_testBtn
(or by code: mc_testBtn.addChild(mcMuteToggle);
Now you can try something like..
mc_testBtn.addEventListener (MouseEvent.CLICK, toggle_Mute );
function toggle_Mute (evt:MouseEvent) : void
{
if ( whatever condition )
{
mc_testBtn.mcMuteToggle.gotoAndStop(2); //go frame 2
}
else
{
mc_testBtn.mcMuteToggle.gotoAndStop(1); //go frame 1
}
}
This is likely due to strict mode. You can either disable it in the ActionScript settings dialog, access it with a different syntax myButton['mcMuteToggle'], or make a class for the symbol that includes a property mcMuteToggle.
You can also check to make sure the symbol is actually on the stage and that clip is actually in the button:
if('myButton' in root) {
// ...
}
if('mcMuteToggle' in myButton) {
// ...
}
i think u just overwrite that codes. You u can use something like this:
var soundOpen:Boolean = true;
var mySound:Sound = new Sound(new URLRequest("Whatever your sound is"));
var mySc:SoundChannel = new SoundChannel();
var mySt:SoundTransform = new SoundTransform();
mySc = mySound.play();
mcMuteToggle.addEventListener(MouseEvent.CLICK, muteOpenSound);
function muteOpenSound(e:MouseEvent):void
{
if(soundOpen == true)
{
mcMuteToggle.gotoAndStop(2);
/*on frame 2 u need to hold ur soundClose buton so ppl can see :)*/
soundOpen = false;
mySt.volume = 0;
mySc.soundTransfrom = st;
}
else
{
mcMuteToggle.gotoAndStop(1);
soundOpen = true;
mySt.volume = 1;
mySc.soundTransfrom = st;
}
}
This is working for me everytime. Hope u can use it well ;)
I am new to as3. I have developed a small application which in as3. But issue is the sprite created does not dispatch any mouse events [ eg: click ]. Please can anyone guide me and throw some comment
.... private var progressBarHolder:Sprite = new Sprite();
progressBarHolder.graphics.clear();
progressBarHolder.graphics.beginFill(0xeaeaea);
progressBarHolder.alpha = 0.5;
progressBarHolder.graphics.drawRoundRect(0, 0, 80, 25, 0,0);
//progressBarHolder.graphics.endFill();
progressBarHolder.width = progressBarWidth;
progressBarHolder.height = 24;
progressBarHolder.x = 48;
progressBarHolder.y = _videoModule.getHeight() - 48;
progressBarHolder.buttonMode = true;
progressBarHolder.addEventListener(MouseEvent.CLICK, progressBarHolderClick);
_overlay.addChild(progressBarHolder);
.....
Thanks!
Code looks ok, possible problems:
width and height of your sprite are not zero (progressBarWidth != 0)
mouse is enabled on parent (_overlay), to make sure use -
progressBarHolder.mouseEnabled = true;
make sure there is nothing above progressBarHolder on the Z index that is blocking the click from the sprite.
Your code is correct. Look up on _overlay or progressBarHolderClick listener. Also It's can happens if property mouseChildren of _overlay or other parent set as false.
Show more code if you still can't find solution.
It seems that if flash.net.NetConnection is instantiated and connected to an HTTP URL (such as an AMFPHP gateway), that instance is never picked up by garbage collection even after it has been closed and the only reference is set to null.
On the other hand, if the instance is connected to null (as would be done when used to play video/mp3 files), the instance is cleared from memory.
To clarify, the following connection will stick around in memory:
var stickyConn:NetConnection = new NetConnection();
stickyConn.connect("http://myserver/amfphp/gateway.php");
stickyConn.close();
stickyConn = null;
Whereas, the following connection will be cleared from memory immediately:
var tempConn:NetConnection = new NetConnection();
tempConn.connect(null);
tempConn.close();
tempConn = null;
Some things I have already tried to solve this issue:
set the client to an empty object (since the default value of the client is the NetConnection itself)
before closing the connection, call connect(null)
after closing the connection, call connect(null) and close it again
Has anyone run into this issue before? Is there a solution to this?
I have built heavyloaded FLV/Mp4 Players using AS3 quite often. When I am using a service like Akamai or Adobe's internal NetConnection Class I always keep in mind the
client object.
the is the property of NetConnection on which ALL callback methods are invoked. The default is this NetConnection instance this. If you set the client property to another object, callback methods will be invoked on that object.
In this way you can easily understand how Garbage Collection was never really applied accross each component in the same way. So, where stickyConn = null; only stops the playback, since you never declared a Weak Reference, Garbage Collection has no clue what to look for.
I have had success with differrent methods based on the specific player:
Simply stating NetConnectionObj.client = this usually suffices. But what if your NetConnection is extended or implementing an interface? Simply use a null Dictionary object:
var d:Dictionary = new Dictionary(true); . From here Garbage collection will recognize "d" as a weak reference and automatically dump it;
Hence, your snippet will look somewhat like this:
var Dc:Dictionary = new Dictionary(true);
NetConnection:NetConnection.client = Dc;
or some variation with the same intent.
I know this works, so reach out if you need help...
I may have been vague with the last answer in regards to GC and Dictionary Objects. Please take this snippet into consideration. I wrote it quickly but I try to explain the Concept of what solves your problem; mainly since I have dealt with it before:
public class Main extends MovieClip {
private var connection:NetConnection;
private var __nData:*;
private var _instance:*;
private var _closure:Function;
private var _D:Dictionary;
public function Main() {
connection = new NetConnection();
connection.addEventListener(NetStatusEvent.NET_STATUS, _nsHandle)
connection.connect(null);
}
public function _nsHandle(event:NetStatusEvent):void {
try {
connection = new NetConnection();
connection.connect(null);
connection.client = RegisterForGC(event.target);
RegisterForGC(connection);
} finally {
__nData = event.target.netConnection;
}
}
public function RegisterForGC(NCObject:*):* {
_instance = NCObject;
_closure = function ():void {}
_listener = function (e:Event):void {}
_D = new Dictionary(true);
_D[_listener] = "A";
_D[_instance] = "B";
_D[_closure] = "C";
try {
new LocalConnection().connect( "A" );
new LocalConnection().connect( "B" );
} catch (anything:*) { }
return _instance;
}
}
I'm not sure but Your example seems to suggest you are declaring your vars on stage / frame.
close(); is all you need for this to work HOWEVER....
from what I have found with NetConnection it for some reason unless all vars / functions are declared in an External class eg. public vars public function,
It stays in memory even after using close();
Pulled out my hair figuring this out with an audio streaming project.
However once I moved all coding to an external class, close(); actually closed the connection.
If your code is on a frame on stage or within MC I would create a class and declare vars & functions in said External Class.as and for some stupid reason it works.
Hope this helps.
Are you using a NetStream object and not disposing of it when finished? I only ask because I rarely see a NetConnection without a NetStream object far behind it.
I am completely new to ActionScript so please understand that I do not know where to begin with this.
I need to show a an objects coordinates on stage as it moves across the screen.
Any help is much appreciated!
thanks,
Alex
Here's a simple approach, you could of course get more detailed with it, for instance check that a value has changed ( i.e. the object is moving ) before updating the TextField text value. You could even use two TextFields, one for the x position, the other for the y.
You may use another type of event listener , it would depend on what makes your object move...
var object:MovieClip = new MovieClip();
var textfield:TextField = new TextField();
object.addEventListener( Event.ENTER_FRAME , positionListener );
function positionListener( event:Event ):void
{
textfield.text = "x:" + object.x.toString() + "| y:" + object.y.toString();
}
thanks!
solution:
addEventListener(Event.ENTER_FRAME, show);
function show(evt:Event):void{
coords_txt.text = object1.x+" - "+object1.y
}
I experienced a problem with the name property in as3, I created this "dot" movieclip and I exported to a class,
then I anonymously created a bunch of dots using a loop. I assigned numbers as name to each dots
private function callDots(num:Number):void
{
for (var i = 0; i < subImagesTotal[num]; i++)
{
var d:Dot = new Dot();
d.x = i*23;
d.y = 0;
d.name = i;
dotContainer.addChild(d]);
}
}
so far so good, I checked that if I trace the name here, I will get the number I want.
However, it's not giving me the numbers if I trace it in other functions.
I added all of my dots to "dotContainer", and if I click on one of the dots, it will call this function
private function callFullSub(e:MouseEvent):void
{
var full_loader:Loader = new Loader();
var temp:XMLList = subImages[sub];
var full_url = temp[e.target.name].#IMG;
full_loader.load(new URLRequest(full_url));
full_loader.contentLoaderInfo.addEventListener(Event.INIT, fullLoaded);
}
e.target.name is suppose to be numbers like 1 or 2, but it's giving me "instance66" "instance70" and I
have no idea why. Because I did the same thing with loaders before and it totally worked.
Any ideas? Thanks.

The e.target returns the inner most object clicked on, this could be a TextField, another MovieClip or posibly a shape (I'm not 100% of the last one) inside the "Dot".
To prevent this you could try to set the mouseChildren property to false on the Dot's when you add them. This should insure that nothing inside the dots can dispatch the click event, and thus the Dot's should do it.
Perhaps you could also in the event handler verify the target type with code like this:
private function callFullSub(e:MouseEvent):void
{
if(!e.target is Dot)
throw new Error("target in callFullSub is not Dot but: " + e.target.toString());
//The rest of you code here
}
The answer is [e.currentTarget.name] I perform this all the time!
Should return "Dot1" "Dot2", etc.
If the value you wish to return is a number or other data type other than a string (name of object) use [e.currentTarget.name.substr(3,1).toString()]
Should return 1, 2, etc.

I tried to reproduce your problem first with Flex using runtime created movieClips and then with Flash using Dot movieClip symbols exported for ActionScript. Neither application exhibited the problem.
You may already know names like "instance66" "instance70" are default enumerated instance names. So, whatever is dispatching the MouseEvent is NOT the dot instance. Perhaps you are unintentionally assigning callFullSub to the wrong targets, maybe your containers? Try assigning it to dot instance right after you create them, like this:
private function callDots(num:Number):void
{
for (var i = 0; i < subImagesTotal[num]; i++)
{
var d:Dot = new Dot();
d.x = i*23;
d.y = 0;
d.name = i;
d.addEventListener(MouseEvent.CLICK, callFullSub);
dotContainer.addChild(d]);
}
}
Be sure to temporarily comment out your original assignment.
Try this might work,..
d.name = i.toString();
You have not shown enough of your code for me to be able to give you a DEFINATE answer, I will however say this.
//After you create each loader you need to set its mouseEnabled
//property to false if you do not want it to be the target of
//Mouse Events, which may be superseding the actual intended target;
var full_loader:Loader = new Loader();
full_loader.mouseEnabled = false;
//Also you could name the loaders and see if what comes back when you click is the same.
ALSO! Add this to your Mouse Event handler for CLICK or MOUSE_DOWN:
trace(e.target is Loader); //If traces true you have an answer
I believe that the mouse events are being dispatched by the Loaders.
please provide more of your code, the code where the Loader.contentLoaderInfo's COMPLETE handler fires. I assume this is where you adding the loaders to the display list as I cannot see that now.
