List Event Listener
Is there a List Event Listener that gets activated every time a different item in the list is selected. The ListSelectionListener sounded like it was activated when the data changed and I wasnt quite sure what all of the ListSelectionEvent methods did.
try using ItemListener
public void itemStateChanged(ItemEvent ie)

Adding an event listener to combo box
I am working on a mortgage calculator and I cannot figure out how to add an event listener to a combo box.
I want to get the mortgage term and interest rate to calucate the mortgage using the combo cox. Here is my program.
Modify the mortgage program to allow the user to input the amount of a mortgage
and then select from a menu of mortgage loans: 7 year at 5.35%, 15 year at 5.50%, and
30 year at 5.75%. Use an array for the different loans. Display the mortgage payment
amount. Then, list the loan balance and interest paid for each payment over the term
of the loan. Allow the user to loop back and enter a new amount and make a new
selection, with resulting new values. Allow user to exit if running as an application
(can't do that for an applet though).

mochatay, here is a new actionPerformed method for you to use.
I've improved a few things here and there...
1) You can't just cast the ActionEvent's source into a JComboBox!
What if it was a JButton that fired the event? Then you would get ClassCastExceptions (I'm sure you did)
So check for all options, what the source of the ActionEvent actually was...
2) You can't assume the user will always type in valid data.
So enclose the Integer and Double parse methods in try-catch brakcets.
Then you can do something when you know that the user has entered invalid input
(like tell him/her what a clumsy idiot they are !)
3) As soon as user presses an item in any JComboBox, just re-calculate.
I did this here by programmatically clicking the 'Calculate' button.
Alternatively, you could have a 'calculate' method, which does everything inside the
if(command==calculateButton) if-block.
This will be called when:
a)calculateButton is pressed
b)when either of the JComboBoxes are pressed.
public void actionPerformed (ActionEvent event)
Object command = event.getSource ();
if (command == calculateButton) //calculates mortgage payment
int year = 0;
double rate = 0;
double mortgage = 0;
double interest = 0;
/* If user has input invalid data, tell him so
and return (Exit from this method back to where we were before */
try
year = Integer.parseInt (mortgageTerm.getSelectedItem ().toString ());
rate = new Double (interestRate.getSelectedItem ().toString ()).doubleValue ();
mortgage = new Double (mortgageAmount.getText ()).doubleValue ();
interest = rate / 100.0 / 12.0;
catch (NumberFormatException nfe)
/* Display a message Dialogue box with a message */
JOptionPane.showMessageDialog (this, "Error! Invalid input!");
return;
double monthly = mortgage * (interest / (1 - Math.pow (interest + 1, -12.0 * year)));
NumberFormat myCurrencyFormatter;
myCurrencyFormatter = NumberFormat.getCurrencyInstance (Locale.US);
monthlyPayment.setText (myCurrencyFormatter.format (monthly));
else if (command == clearButton) //clears all text fields
/* Better than setting it to null (I think) */
mortgageAmount.setText ("");
//mortgageTerm.setText(null);
//interestRate.setText(null);
monthlyPayment.setText ("");
else if (command == exitButton) //sets exit button
System.exit (0);
else if (command == mortgageTerm)
/* Programmatically 'clicks' the button,
As is user had clicked it */
calculateButton.doClick ();
else if (command == interestRate)
calculateButton.doClick ();
//JComboBox mortgageTerm = (JComboBox) event.getSource ();
//String termYear = (String) mortgageTerm.getSelectedItem ();
}Hope this solves your problems.
I also hope you'll be able to learn from what I've indicated, so you can use similar things yourself
in future!

I'm having some trouble trying to figure out how this event listener will work.
The main application is building an arrayCollection of a calendarDay custom components which is displayed by a DataGroup.
Within each calendarDay custom component i may create an arrayList of a DriverDetailComponent custom components displayed within the calendarDay by a DataGroup.
If a user double clicks on the DriverDetailComponent that is two layers in I would like to change states of the main application. I'm having trouble figuring out what item in the main application to set the listener on. Please help.
I can't figure out how to post the below as scrollable code snips so this is very long.

JComboBox: how to capture the internal list events?
Hi
Does anybody know how to capture JComboBox internal list events, what I mean
is when I click the box arrow button a list of the items pops up and as you move the mouse inside that list up and down, an items gets highlighted.
So I am interested in capturing those events - basically when the next item from the list is highlighted.
ThanksYou can add an item listener to the combo box for that. IIRC, your listener will get
notified twice: once for the deselection of the previous item, and once for the new
item's selection.

Removing a Button Event Listener on a Specific Frame and Reactivating it on Next Frame
Hi , i am trying to develop a Slideshow where Next Button needs to behave in a certain way on a specific Frame , lets say a Specific Condition is met only then Next Button would work , I have been able to achieve that but problem is the Button Retains its Event Listener even on the next Frame , whereas i have already included removeEventListener on the next frame with a new Function for the button , but its doesnt take it like that.

I am repeating this Pattern on each frame set where I need these Listeners ,
Problem is with the next one where I have two consecutive frames have different conditions to meet, any ideas how would I disable and enable listeners respectively on these frames ?
I hope I am not confusing this very much ?;( -
I'm trying to define an event listener for a JList component. The code is shown below. The problem i'm having is that when elements are added to the JList none of the functions (callFunctionHere()) are being called. Can anyone tell me what i'm doing wrong? (elements are being added to the list using DefaultListModel.addElement())
pnlWhere.lstCond.getModel().addListDataListener(new javax.swing.event.ListDataListener() {
public void contentsChanged(ListDataEvent e) {
callFunctionHere();
public void intervalRemoved(ListDataEvent e) {
callFunctionHere();
public void intervalAdded(ListDataEvent e) {
callFunctionHere();
});Thanks,
Danny.Check out the KeyListener interface. You can create an implementation that searches for a string starting with the character of the key that was pressed.

Error trying to register a Java event listener
I'm trying to register a java event listener in 11g with the following piece of code:
DECLARE
b BOOLEAN := FALSE;
BEGIN
b := DBMS_XDB.createFolder('/public/resconfig');
b := DBMS_XDB.createResource(
'/public/resconfig/hr_event.xml',
'<ResConfig xmlns="http://xmlns.oracle.com/xdb/XDBResConfig.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.oracle.com/xdb/XDBResConfig.xsd
http://xmlns.oracle.com/xdb/XDBResConfig.xsd">
<event-listeners default-language="Java">

<description>Category application</description>
<schema>HR</schema>
<source>xdbproject.OpenOfficeEventHandler</source>

<events>
<Post-Create/>
<Post-LinkIn/>
</events>
</listener>
</event-listeners>
<defaultChildConfig>
<configuration>
<path>/public/resconfig/hr_event.xml</path>
</configuration>
</defaultChildConfig>
</ResConfig>');
END;
This results in the following error message
ORA-31146: Ugyldig lytterkilde HR.xdbproject.OpenOfficeEventHandler
ORA-06512: ved "XDB.DBMS_XDB", line 174
ORA-06512: ved line 5
which translates to Invalid listener source.
My class is loaded in the HR schema, and implements the XDBRepositoryEventListener
Does anybody have a suggestion to what I'm doing wrong, or how I can find out what makes my class invalid as a listener source?Check if it validates against the restrictions set in the XML Schema (Appendix A, Oracle XMLDB Developers Guide):

Help -- Script timing out during http event listener
So, I have created an HTTPService to retrieve an XML file. The event listener is basically just parsing that XML file and doing another necessary calculation. Unfortunately, the script times out because while small in size, there's a lot of data in it. I know there's a way to override this with the compiler, but this doesn't seem like a smart thing to do. What are other solutions?
I need the XML data to be loaded when the Flash player loads because it basically displays graph data that people need to be able to see as soon as the page finishes loading.
Thanks so much for you input. I didn't anticipate this timeout problem!I changed my code to use the URLLoader(), not that it would resolve the problem, but maybe it's the preferred way to do this?
Project Overview (that's relevant):
The XML data is a bunch of numbers that I need to display on a graph as soon as the page is loaded. So, it must be parsed and obviously remapped to the height of the panel.
The mostly relevant code:
// openXML() is being called by my controller, which is called by my application's initialize
public function openXML():void {
var loader:URLLoader = new URLLoader();
loader.addEventListener(Event.COMPLETE, loadXML);
loader.load(new URLRequest(xmlURL));
private function loadXML(evt:Event):void {
trace("start");
var xml:XML = new XML(evt.target.data);
// setup all <R> (Reading) tags as an xml list
xmlList = xml.R;
for (var i:int=0;i<xmlList.length();i++) {
value[i]=xmlList.v[i];
// each value will then need to be remapped to fit the panel
// call the gsrController -- which will in turn draw all this stuff
So the problem is, I'm new to Flex, and the lack of multithreading seems to be hurting me? I would LOVE for a way for the openXML() file to be able to return the xmlList so that I can take all of that logic OUT of that event listener, which is the way it should be. But how could I do that? I don't think that I can tell openXML() to wait on that event listener before it returns anything - haha.
When I was testing this stuff a few days ago, everything was working perfectly, it was when I used data that corresponded to 40 minutes worth of video that it became a problem!
(And to provide a better overview of what I'm doing, the XML data is for drawing this line that the video player ticker is syncing up with as the video plays......) -
Hi all,
There's List object (myList) in the stage, but the following scripts does not work:
========================================
addEventListener(MouseEvent.CLICK, connectHandler);
function connectHandler(event:MouseEvent):void{
switch(event.target.name){
case "myList":
trace(event.target.name)
=====================================
The script "myList.addEventListener(ListEvent.ITEM_CLICK, itemClick)" works without problem. I would like to know why the scripts above do not work in List Object.
In additional, is it possible to achieve this feature by using List:
When I click a specific row of a list object, a event will occur. Example:
There’s list:
A,
B,
C,
When I click B and then an event will occur. Click C, another event will occur. Thank you!The code above didn't work because you added the event listener to the main timeline. Since you want an event listener for myList then you have to add it to that object as you did after the code. You can use ListEvent.ITEM_CLICK to listen to each of the row items click event:
import fl.data.DataProvider;
import fl.controls.List;
import fl.events.ListEvent;
var dp:DataProvider = new DataProvider();
dp.addItem( { label:"Item 1" } );
dp.addItem( { label:"Item 2" } );
myList.iconField = "iconSource";
myList.dataProvider = dp;
myList.addEventListener(ListEvent.ITEM_CLICK, connectHandler);
function connectHandler(e:ListEvent):void {
var list:List = e.target as List;
var item:Object = e.item;
trace("Label: " + item.label);
trace("Label displayed: " + list.itemToLabel(item)); -
Hello everyone,
I have a List with some elements in. I would like to handle the list events such that i.e. when the selectedIndex changes, a specific action to happen.
For example if the list elements are music file names, by changing the cursor from one element to the next one without pressing any buttons (no command listener) the new selected file should start to play.
How do we normally do that? Does ItemStateListener help?
Thank you.I don't think you willbe able to do this with a List. Lists don't have any items, so you can't set an ItemStateListener. The ItemStateListener is used for the classes which extend Item, such as TextField, ChoiceGroup etc. So you would need to create a form and add some items to it for this to work. But even then the ItemStateListener only does something when the state changes, such as changing the text in a TextField etc.
To get this to work using LCDUI components you would have to create a CustomItem to represent each music track. This means doing all of the drawing yourself (which means it won't match the phone's theme). Within the CustomItem you can handle the traversal actions, i.e. on traverse in you could play the track and traverse out you could stop it. If you want to use this you should search for help on creating CustomItems, they can be quite tricky.
Alternatively you can create your own screen using Canvas (again this would not match the phone's theme). Here you can control the key pressed events and move between tracks and do whatever you want when one track is selected. -
Can't remove event listener from Image
I'm clearly missing something and would appreciate some help. I'm trying to run an event handler when an Image completes loading, then remove the handler so that it won't run again should the image be reloaded later.
The problem that I'm having is that the event handler simply wont' go away, despite calling removeEventListener on the Image object.
The following example demonstrates the problem (the example doesn't actually do anything useful...it's just the shortest example to demonstrate the problem). (To run the app, you'll have to provide any ol' JPEG file named "myImage.jpg" in the "src" directory of your project).
What I expect to happen is :
1) on startup, the image loads and loadComplete() runs.
2) loadComplete removes the event Listener so that subsequent re-loads won't re-fire the handler. I only want the handler to run once.
3) "loadComplete" shoudl be displayed in the Debug console.
4) A button click should display only "Changing Image" in the Debug console
What I get instead is that the loadComplete handler isn't removed, and every time I click the button, loadComplete runs when the image is re-loaded (i.e., every button click results in both "Change Image" AND "loadComplete" being displayed in the Debug console).

]]>
</mx:Script>
</mx:Application>Hi,
You can remove only event listeners that you added with the addEventListener() method in an ActionScript block. You cannot remove an event listener that was defined in the MXML tag, even if it was registered using a call to the addEventListener()method that was made inside a tag attribute.
Check this page for reference.
http://livedocs.adobe.com/flex/3/html/help.html?content=events_05.html
You can modify the code a bit a get it working
<mx:Image width="655" height="181" id="myImage" scaleContent="true"
x="100" y="100"
creationComplete="myImage_creationCompleteHandler(event)"/>
private function myImage_creationCompleteHandler(event:FlexEvent):void
myImage.addEventListener("complete",myImage_completeHandler);
myImage.load("myImage.jpg");
private function myImage_completeHandler(event:Event):void
myImage.removeEventListener("complete",myImage_completeHandler); -
I'm trying to assign a mouseclick event listener to a simplebutton nested within a movie clip's later frames, starting at frame 2 and up. This card, however, is not added to my game until later, and when the player clicks on it/turns it over.
There are four files involved in this program:
#1 The main actionscript file, which corresponds to
#2 my dreamQuester .fla file.
#3 my artifactCard file movieClip's corresponding .as file,
#4 my combo1.as file corresponding to a an instance of a simpleButton named combo1 that is already
nested --and this instance is already named-- inside/as a child of said artifactCard movieclip.
What I've done so far isn't working:
In my main dreamQuester.as file, when a player clicks on an artifactCard, its MOUSE_DOWN event
listener takes them to this function (clickArtCard), where the trouble is at:
// player clicked on the artC card--which is a child of posArt1 on stage--to turn card over:
function clickArtCard(a_event:MouseEvent) {
var thisArtCard:artifactCard = (a_event.target as artifactCard);
thisArtCard.gotoAndStop(unclickedArt1); // go to frame number of artifact
// card where combo1 button is.
thisArtCard.removeEventListener(MouseEvent.CLICK,clickArtCard);
thisArtCard.buttonMode = false;
trace("combo1.combo is:" + combo1.combo);
trace("posArt1.artC.combo1 is:" + posArt1.artC.combo1);
posArt1.artC.combo1.addEventListener(MouseEvent.MOUSE_DOWN, comboClickedWHO);
when the artC card--the static public instance of artifactCard--is clicked, it only gets to the
trace("posArt1.artC.combo1 is:" + posArt1.artC.combo1); which returns this error message:
TypeError: Error #1010: A term is undefined and has no properties.
at MethodInfo-61()
So do how would I declare a static public variable of this simpleButton at the start of my main .as
file to make it defined to get a mouseDown actionListener into my pre-existing-and-named-instance
combo1 simpleButton?
perhaps there is a way, while the debug movie program is running, to click on the simpleButton and see exactly
what it's parent heirarchy is, to see the name of all parents above the simpleButton incase they are
different then what I think?
(just in case, I was hoping to squeeze a zip file containing these files to be less than 9MB incase someone was willing to look at my files to see what I've done so far, but 9 megs is just too big! even though all graphics I've imported where turned into vector graphics with trace bitmap. I wish there was a way to check the file size of each symbol in Flash CS4, here...)
Thank you so much for any help!
~EthanJust use a
stage.addEventListener(KeyboardEvent.KEY_DOWN, keyPressed);
function keyPressed(event:KeyboardEvent):void {
//trace(event.keyCode);
if(event.keyCode == ???){
// play the sound
Where I show the "???" you would replace with the keyCode for the key you want pressed for that sound. To determine the keyCode you can use the trace line that I have commented out.
Note that when testing in Flash you often need to disable the keyboard shortcuts in the Flash Player in order to be able to use alot of the keys. You will find this option in the Control menu options in the player. -
How can I check if a function is or is not called from the event listener? in Flash CS4 (AS3)
Hi,
I came across a little problem.
I put an event listener inside a for loop and the for loop inside a function.
I want the for loop to end as soon as the event listener inside the for loop calls its function.
Here is the general code for a better picture.
Code:
this.addEventListener(Event.ENTER_FRAME, function#1);
function function#1(event:Event):void{
if(something is true){
for(var i = 0; i < numOfmy_mcs; i++){
this["my_mc_"+String(i)].addEventListener(MouseEvent.CLICK, function#2);
function function#2(e:Event):void{
//do something cool here
Thank you for any help!kglad wrote:
that for-loop (if it executes), defines listeners for interactive objects. that will complete long before any object is clicked.
Well yes but it does it again and again (frames per second times seconds = number of times it goes through the code if i'm not mistaken), because it is inside a function, and through testing i found out that it works like this:
Example:
there are 5 my_mc's in my project: (my_mc_0, my_mc_1, my_mc_2, my_mc_3, my_mc_4)
if i click my_mc_0 function#2 is called and executed. BUT only after the loop finishes (i know this from tons of testing)...which is unnecessary since you cannot click two places at once. This might not be a problem in this example because i am only using 5 my_mc's buy if i use 500000000 my_mc's it would make a lot of difference.
is there a way to stop the loop if the function is called?
...maybe there is a better way to write it, the only alternative i know that works is if i manually write every single listener and this also is logical in this example but as i said next to impossible if the numbers get bigger.
-Note
I didn't specify this earlier but function#2 makes the if statement false so it wont jump back into it.
Thank you for the help I really appreciate it!
3rd edit...don't know what's wrong with me -
Remove event listener from loaded external swf
I have a main movie timeline that loads an external swf. When I unload the swf from the main timeline I get an error from this: my_FLVPlybk.addEventListener(VideoEvent.COMPLETE, vidEnd);
is there any way to remove the event listener from the loaded swf from the main timeline?
THANKS!if you're publishing for fp 10+, use unloadAndStop() applied to your swf's loader. that has a fair chance of solving the problem.
if that fails, you should explicitly stop my_FLVPlybk. -
Keyboard Event Listener doesn't work in Browser
Is there a reason why a keyboard event listener would not work if the flash is embedded in an HTML? The rest of my game is running fine in the background, but I can't launch the movieClip "nextCar." My code is below, if that makes any difference...
function goNow (event:KeyboardEvent): void {
thisOtherKey = event.keyCode;
if (thisOtherKey == 32) {
nextCar.gotoAndPlay(2);
parkingQue.play();
tries++;
stage.addEventListener(KeyboardEvent.KEY_DOWN, goNow);This may be a silly question, but have you tryed clicking on your swf after it opens up in the browser, and then trying the keyboard controls?
I don't know of any issues that cause event listeners to workwhen debugging, but not in a browser. So, I'm thinking maybe your just not focused on the swf.
