Handling Custom JavaScript Events from HtmlLoader Class

Hey guys, just a quick question, Is it possible to handle custom javascript events just the way standard events like locationchange and DOMInitialized are handled. Say for example a HTML5 slide application that dispatches custom events when the user moves from one slide to another. I know there is an option to use ExternalInterface to talk to AS3 but for this project of mine, this is not an oiption as this HTML5 Presentation doesnt have any swf content to bridge with.
Its just a thought since the HTMLloader has access to the javascript window object(or am i wrong). Would it be possible to access a custom function as a prototyped property of the window Object.
Any form of tip/clarification will be appreciated.
thanks!

Use the HTMLHost class. You create a subclass of HTMLHost and override certain methods that are called in response to certain JavaScript behaviors. Then you assign an instance of your HTMLHost to the HTMLLoader's htmlHost property. (Since you're using the Flex HTML component, you would assign your HTMLHost subclass instance to the HTML control's htmlHost property.)

Calling Portal event from ABAP class

Hi Experts,
I need a following clarificatrion, Please help,
1. Is it possible to call a webdynpro method from a normal ABAP class?
2. If no, we need a functionality of a class 'CL_WDR_HTTP_EXT_MIME_HANDLER' having method 'DO_DOMAIN_RELAX_HTML'.
Is there any alternative method which can be used in ABAP having the same functionality.
3. Is there any ways with which we can call portal event from ABAP class?
Thanks,
Shabir

>1. Is it possible to call a webdynpro method from a normal ABAP class?
I wouldn't necessarily recommend this approach. You shouldn't try to trigger events or any of the standard WDDO* methods from outside the WD Component itself. That said, you can pass the object reference (like the WD_COMP_CONTROLLER object reference or the View Object Reference) into methods of normal classes. Be careful if you are finding yourself calling a lot of your added methods from outside WD. This is probably a sign that these methods should be in the Assistance Class or some other Class functioning as a Model Object.
>2. If no, we need a functionality of a class 'CL_WDR_HTTP_EXT_MIME_HANDLER' having method 'DO_DOMAIN_RELAX_HTML'.

What exactly do you want to do here? Do you just want to get the relaxation script? For what purpose? You should never need to inject the relaxation script into WDA.
>3. Is there any ways with which we can call portal event from ABAP class?
To what purpose. Do you just want to delegate the triggering of the event that is inside WD Component to be called from a class? If so you can pass the portal API object reference into a class from the WD Component. However this only works while running within WD.
How is this class used? Are you running in WD? Are you trying to generate some HTML code that runs in the portal independent of WD?

Fire event from one class to another.

I have a Login JFrame class that allows users to enter username and password. I then have another JFrame class which will monitor when someone logs in. I am trying to get the username and password to appear on the monitor login frame text area when the user presses enter on the login frame.
I can get it ot work by passing the Monitor class into the Login classes constructor but I want to be able to open the classes separately.When I try to open separatley at present I get java.lang.NullPointerException
     at project.LoginGUI.actionPerformed(LoginGUI.java:70) which is referring to the following code:
if(listen.equals("OK")){
     GymMonitor.username.setText(username.getText());
Both classes are in the same package. What I want to know is how to fire an event from one class to another? when the class you are firing to is constructed separately.
I hope this question is not too verbose.
Thanks

Generally for something like this you would use a listener.
Your login window is its own entity--it has a user interface, and it gets some information which someone else could ask it for. It could even generate its own events, such as when the user presses "OK". You would first define an interface for anyone who wants to know when someone logs in:
public interface ILoginListener extends java.util.EventListener
public void login(LoginEvent event);
}You would then define the LoginEvent class to contain information like what the user entered for username and password. You could give your login dialog a couple of methods:
private Vector myListeners = new Vector();
public void addLoginListener(ILoginListener listener) {
    myListeners.add(listener);
public void removeLoginListener(ILoginListener listener) {
    myListeners.remove(listener);
protected void fireLogin(LoginEvent event) {
    for (Iterator it = myListeners.iterator(); it.hasNext(); ) {
      ILoginListener listener = (ILoginListener)it.next();
      listener.login(event);
}You'd have your login dialog call fireLogin every time the user logged in.
Then, you could implement ILoginListener in your monitor window:
public void login(LoginEvent event) {
    // now do something with the event you just got.
}All the code I put in here is really generic stuff. You'll write this kind of stuff hundreds of times probably during your career. I haven't tested it though.
Hope this helps. :)

Catching event from canvas class

Hi,
I want to catch an event from MyCanvas class/obect to MyMidlet class/object. I have implemented keypressed method in MyCanvas. can i use it pr do i have to do something else..
Any ideas?
Cheers
Indy

hi mlk!
well, i want to catch Canvas.Fire event. sorry but i should have given you an idea of the code. well here it is:
public class MyMIDlet extends MIDlet implements CommandListener {
private Display display;
private MyCanvas canvas;
private Command exitCommand = new Command("Exit", Command.SCREEN, 1 );
public MyMIDlet(){
canvas = new MyCanvas(this);
protected void startApp(){
display.setCurrent(canvas);
canvas.addComman(exitCommand);
canvas.setCommandListener(this);
public void commandAction( Command c, Displayable d ){
     if( c == exitCommand ){
     exit();
public class MyCanvas extends Canvas{
protected void keyPressed(int keyCode) {
     if(keyCode < 0)
     int key = getGameAction(keyCode);
if(key == Canvas.FIRE){
     System.out.println("FIRE");
So, when Canvas.FIRE is 'pressed' i want MyMIDLET to know that it happend..
thanks again

Need help with custom event from Main class to an unrelated class.

Hey guys,
I'm new to Flash and not great with OOP. I've made it pretty far with google and lurking, but I've been pulling my hair out on this problem for a day and everything I try throws an error or simply doesn't hit the listener.
I'm trying to get my Main class to send a custom event to an unrelated class called BigIcon. The rest of the code works fine, it's just the addEventListener and dispatchEvent that isn't working.
I've put in the relevant code in below. Let me know if anything else is needed to troubleshoot. Thank you!

Alright, this compiles, gives me no errors, shows my 'book' and 'flowers' icons perfectly when ran, and prints 'addEventListener' to the output window as expected. I get no errors when I press the button, 'dispatchEvent' is output (good), but the 'twitchUp' function is never called and 'EventTriggered' is never output.
How do I get the 'twitchUp' event to trigger?

Handling standard iview event from web dynpro

Hi all,
I hav w a search iView which is SAP standard, when you click an element on the result list it triggers an event. The link contains the following:
javascript:{jsCode="
EPCM.storeClientData('urn:com.sap.bor:BUS1001','objid','12002');
EPCM.storeClientData('urn:com.sap.bor:BUS1001','AllKeys','objid');
EPCM.raiseEvent('urn:com.sap.bor:BUS1001','select','','a very long url');"};if(opener!=null&&self!=opener){opener.execJS(jsCode);}else{execJS(jsCode);};
On the other side I'm developing a custom WebDynpro iView whick needs to handle this event. By adding to wdInit() the line WDPortalEventing.subscribe("urn:com.sap.bor:BUS1001", "select", wdThis.wdGetGetReportsListForMaterialAction()); I was able to catch the event. But I can't get the parameters from the event.
For what i've learned browsing the forum the javascript code above stores the parameters in the "client data bag", and are not directly passed in the event.
Is there any way to retrieve these parameters from the Web Dynpro iView ?
Thanks in advance,
Diego.

Hi all,
As a workaround I made a Portal Component application which receives the event and parameters from the standard iView and lanuchs a new event setting the aprameters in the event as Web Dynpro expects them (without using the client databag). Then I inserted this Iview in the same page as the others, but hidden. It's not elegant but is working.

Add/Remove datagridview event from other class

Hi,
I have a 'Class A' which have a datagridview object with cellvaluechanged event. i pass this datagridview as byreference to 'Class B'.
i need to remove/add the cellvaluechanged event of given datagridview object from 'Class B'.
below is my code
Thanks and Regards
Kasim

Hi Thangam-Kasim,
If you want to add/remove the event of DataGridView in ClassB.
You need to add a reference of Class A in Class B.
I supposed the ClassA is Form1, The Class B is Form2. in Form2, there is a method called SetDataSource() like yours.
Then you could add/remove the event like below.
Public Sub SetDataSource(ByVal dt As DataTable, ByRef DGView As DataGridView)
Dim dgvrow As DataGridViewRow
If DGView.Rows.Count > 0 Or DGView.DataSource IsNot Nothing Then
DGView.Rows.Clear()
End If
Dim form1 As Form1 = Application.OpenForms.OfType(Of Form1)().FirstOrDefault()
RemoveHandler DGView.CellValueChanged, AddressOf form1.DataGridView1_CellValueChanged
AddHandler DGView.CellValueChanged, AddressOf form1.DataGridView1_CellValueChanged
End Sub
In Form1, you need to set the DataGridView1_CellValueChanged method to Public.
If you have any other concern regarding this issue, please feel free to let me know.

Calling a JavaScript function from my class

Here's the situation. I am trying to access a website (not my own) through a class I am writing. Some information that I need to pull off the page can only be seen when a JavaScript function is called. How can I make the page call the function from my own computer?

Well, you could use a tool like this:
http://httpunit.sourceforge.net/
If the Javascript you want to call into is relatively simple it may work ok for you, but there's no guarantee - differences between the browser's libraries and the Rhino (Java's embedded Javascript) libraries may make the exercise intractable.
You might alternatively be able to invoke the browser from Java and then screen scrape it somehow, but I can't help you with that - and it's a distinctly inelegant solution.
If you have a legitimate reason for doing this, your best bet would be to contact the website owner and see if they can accommodate you somehow; they may even have a suitable services API for you to call into without messing about trying to render the Javascript. If you don't have a legitimate reason for doing this (one the website owner would be ok with) then my sympathy for your plight is rather limited anyway.

Bug fix requires switching touch events from symbols/classes to the main stage?

Also posted in Mobile Development, I'm still not sure which forum I should be in.

Bug ID #2940816
I have an app that wasn't compiling correctly. I sent the bug to Adobe who responded with a workaround. However, I can't figure out how to make their stated workaround work in my code.
I have puzzle pieces on the stage. Each is assigned to a separate class. Inside the class I have touch events defining multiple touch events for each piece.
I have another spot on the stage where, when it is touched, a puzzle piece appears. These are also each linked to a separate class. Inside this class I also have touch events defining multiple touch events for each piece.
Though it works fine on my computer, it wasn't working on an iPad. Adobe said that I needed to switch the touch events so that they were assigned to the main stage instead of to each individual object.
However, the code they gave me didn't really make sense in context and I'm confused how to implement it.
This is the code in the class for each piece that is created when you touch the stage:
        public function GeoPiece(): void {
            if (PuzzleGlobals.currentLevel == "Name") {
                this.gotoAndStop("wholeName");
            else if (PuzzleGlobals.currentLevel == "Abbrev") {
                this.gotoAndStop("abbrev");
            else if (PuzzleGlobals.currentLevel == "Shape") {
                this.gotoAndStop("shape");
            this.addEventListener(TouchEvent.TOUCH_MOVE, geoPieceBegin);
        public function geoPieceBegin (e:TouchEvent): void {
            PuzzleGlobals.pieceActive = true;
            e.target.startTouchDrag(e.touchPointID, false);
            e.target.addEventListener(TouchEvent.TOUCH_END, geoPieceEnd);
            e.target.interactionBegin();
            MovieClip(this.parent.parent).nameDisplay.gotoAndStop(e.target.abbrev );
            PuzzleGlobals.currentPiece = e.target.abbrev;
        public function geoPieceEnd (e:TouchEvent): void {
            PuzzleGlobals.pieceActive = false;
            if (currentObjOver.isLocked == true) {
                currentObjOver.gotoAndStop ("Lock");
            else {
                currentObjOver.gotoAndStop ("Out");
            MovieClip(this.parent.parent).nameDisplay.gotoAndStop(PuzzleGlobals.c hosenPuzzle);
            e.target.stopTouchDrag(e.touchPointID);
            if (this.dropTarget.parent is GeoPuzzle) {
                if (GeoPuzzle(this.dropTarget.parent).abbrev == e.target.abbrev) {
                    PuzzleGlobals.statesCompletedUSA++;
                    GeoPuzzle(this.dropTarget.parent).isLocked = true;
                    GeoPuzzle(this.dropTarget.parent).gotoAndStop("Lock");
                    e.target.parent.removeChild(DisplayObject(e.target));
                else {
                    //play BOOP sound indicated wrong drop;
            if (PuzzleGlobals.statesCompletedUSA == PuzzleGlobals.TOTAL_NUMBER_USA) {
                //play fireworks game
            else {
                //do nothing
            e.target.removeEventListener(TouchEvent.TOUCH_END, geoPieceEnd);
        public function interactionBegin () {
             if (this.dropTarget != null && this.dropTarget.parent is GeoPuzzle) { //check to make sure it's over a puzzle piece
                currentObjOver = GeoPuzzle(this.dropTarget.parent);
                currentObjOver.gotoAndStop("Over");
            if (lastObjOver != currentObjOver) {
                if (lastObjOver.isLocked == true) {
                    lastObjOver.gotoAndStop("Lock");
                else {
                    lastObjOver.gotoAndStop("Out");
                lastObjOver = currentObjOver;
This is the code in the class for each piece that's already on the stage:
        public function GeoPuzzle(): void {
            if (this.isLocked == true) {
                this.gotoAndStop ("Lock");
            if (PuzzleGlobals.pieceActive == true) {
                this.addEventListener(TouchEvent.TOUCH_BEGIN, geoPuzzleBegin);
        public function geoPuzzleBegin (e:TouchEvent): void {
            e.target.addEventListener(TouchEvent.TOUCH_END, geoPuzzleEnd);
            e.target.gotoAndStop("Over");
            MovieClip(this.parent).nameDisplay.gotoAndStop(e.target.abbrev);
        public function geoPuzzleEnd (e:TouchEvent): void {
            if (e.target.isLocked == false) {
                e.target.gotoAndStop("Off");
            else if (e.target.isLocked == true) {
                e.target.gotoAndStop("Lock");
            MovieClip(this.parent).nameDisplay.gotoAndStop(PuzzleGlobals.chosenPu zzle);
            e.target.removeEventListener(TouchEvent.TOUCH_END, geoPuzzleEnd);
You can see that each piece (whether it's already locked on the stage or movable) reacts differently to different touch events. However, this is the code that Adobe gave me as a workaround:
this.stage.addEventListener(TouchEvent.TOUCH_BEGIN, onTouchEvent);
this.stage.addEventListener(TouchEvent.TOUCH_MOVE, onTouchEvent);
this.stage.addEventListener(TouchEvent.TOUCH_END, onTouchEvent);
var beginCount:uint=0;
var moveCount:uint=0;
var endCount:uint=0;
function onTouchEvent(event:TouchEvent):void{
     switch (event.type){
          case TouchEvent.TOUCH_BEGIN:
           &nbs p;           &n bsp; trace("BEGIN")
           &nbs p;           &n bsp; beginCount++;
           &nbs p;           &n bsp; square.x = event.stageX;
           &nbs p;           &n bsp; square.y = event.stageY;
           &nbs p;           &n bsp; square.startTouchDrag(event.touchPointID, false);
           &nbs p;           &n bsp; break;
          case TouchEvent.TOUCH_MOVE:
           &nbs p;           &n bsp; trace("MOVE")
           &nbs p;           &n bsp; moveCount++;
           &nbs p;           &n bsp; break;
          case TouchEvent.TOUCH_END:
           &nbs p;           &n bsp; trace("END")
           &nbs p;           &n bsp; endCount++;
           &nbs p;           &n bsp; square.stopTouchDrag(event.touchPointID);
           &nbs p;           &n bsp; break;
     trace("begin: "+beginCount+" move: "+moveCount+" end: "+endCount);
//     countText.text = "begin: "+beginCount+" move: "+moveCount+" end: "+endCount;
This doesn't make any sense to me because it seems that it would only work if touching the stage had to react in just a single way. I have multiple pieces that need to each react differently.
1. The pieces that are locked to the stage need to highlight when touched and display their name.
2. These pieces also need to keep themselves highlighted and their names displayed when the touch is dragged off of them instead of just removed.
3. Each piece needs to be created when touching the Puzzle Piece button the stage. As these pieces are dragged, they need to highlight the pieces underneath them and unhighlight them when they are dragged off. They also need to display their own names, and lock into place when they are dragged over the correct piece.
My questions are:
1. Why don't touch events work in the compiler?
2. How can I translate my current working code's touch events to all be directly linked to the stage instead of their objects?
Thanks so much!

Sure!
I haven't changed much. I've been playing around and I think I know where the problem is coming from now. I just can't figure out how to fix it.
This it the only code I've modified:
        public function interactionBegin () {
            trace ("Current: " + currentObjOver);
            trace ("Last: " + lastObjOver);
            if (this.dropTarget != null && this.dropTarget.parent is GeoPuzzle) { //check to make sure it's over a puzzle piece
                currentObjOver = GeoPuzzle(this.dropTarget.parent); //make "currentObjOver" assigned to the puzzle piece the finger is currently touching
                currentObjOver.gotoAndStop("Over"); //highlight the current piece
                if (currentObjOver != lastObjOver) { //if your finger moves and you're now touching a different state
                    if (lastObjOver != null && lastObjOver.isLocked == true) { //if the previous state you were touching has been solved
                        lastObjOver.gotoAndStop("Lock"); //lock this state into place
                    else if (lastObjOver != null && lastObjOver.isLocked == false) { //if the previous state you were touching wasn't solved
                        lastObjOver.gotoAndStop("Off"); //unhighlight that state
                    lastObjOver = currentObjOver; //assign the current state to be the last state you were touching
lastObjOver and currentObjOver are always assigned the same object. I can't figure out why, I've run it line by line but I can't figure out where I'm going wrong.

Switching touch events from symbols/classes to the main stage?

Bug ID #2940816
I have an app that wasn't compiling correctly. I sent the bug to Adobe who responded with a workaround. However, I can't figure out how to make their stated workaround work in my code.
I have puzzle pieces on the stage. Each is assigned to a separate class. Inside the class I have touch events defining multiple touch events for each piece.
I have another spot on the stage where, when it is touched, a puzzle piece appears. These are also each linked to a separate class. Inside this class I also have touch events defining multiple touch events for each piece.
Though it works fine on my computer, it wasn't working on an iPad. Adobe said that I needed to switch the touch events so that they were assigned to the main stage instead of to each individual object.
However, the code they gave me didn't really make sense in context and I'm confused how to implement it.
This is the code in the class for each piece that is created when you touch the stage:
        public function GeoPiece(): void {
            if (PuzzleGlobals.currentLevel == "Name") {
                this.gotoAndStop("wholeName");
            else if (PuzzleGlobals.currentLevel == "Abbrev") {
                this.gotoAndStop("abbrev");
            else if (PuzzleGlobals.currentLevel == "Shape") {
                this.gotoAndStop("shape");
            this.addEventListener(TouchEvent.TOUCH_MOVE, geoPieceBegin);
        public function geoPieceBegin (e:TouchEvent): void {
            PuzzleGlobals.pieceActive = true;
            e.target.startTouchDrag(e.touchPointID, false);
            e.target.addEventListener(TouchEvent.TOUCH_END, geoPieceEnd);
            e.target.interactionBegin();
            MovieClip(this.parent.parent).nameDisplay.gotoAndStop(e.target.abbrev);
            PuzzleGlobals.currentPiece = e.target.abbrev;
        public function geoPieceEnd (e:TouchEvent): void {
            PuzzleGlobals.pieceActive = false;
            if (currentObjOver.isLocked == true) {
                currentObjOver.gotoAndStop ("Lock");
            else {
                currentObjOver.gotoAndStop ("Out");
            MovieClip(this.parent.parent).nameDisplay.gotoAndStop(PuzzleGlobals.chosenPuzzle);
            e.target.stopTouchDrag(e.touchPointID);
            if (this.dropTarget.parent is GeoPuzzle) {
                if (GeoPuzzle(this.dropTarget.parent).abbrev == e.target.abbrev) {
                    PuzzleGlobals.statesCompletedUSA++;
                    GeoPuzzle(this.dropTarget.parent).isLocked = true;
                    GeoPuzzle(this.dropTarget.parent).gotoAndStop("Lock");
                    e.target.parent.removeChild(DisplayObject(e.target));
                else {
                    //play BOOP sound indicated wrong drop;
            if (PuzzleGlobals.statesCompletedUSA == PuzzleGlobals.TOTAL_NUMBER_USA) {
                //play fireworks game
            else {
                //do nothing
            e.target.removeEventListener(TouchEvent.TOUCH_END, geoPieceEnd);
        public function interactionBegin () {
            if (this.dropTarget != null && this.dropTarget.parent is GeoPuzzle) { //check to make sure it's over a puzzle piece
                currentObjOver = GeoPuzzle(this.dropTarget.parent);
                currentObjOver.gotoAndStop("Over");
            if (lastObjOver != currentObjOver) {
                if (lastObjOver.isLocked == true) {
                    lastObjOver.gotoAndStop("Lock");
                else {
                    lastObjOver.gotoAndStop("Out");
                lastObjOver = currentObjOver;
This is the code in the class for each piece that's already on the stage:
        public function GeoPuzzle(): void {
            if (this.isLocked == true) {
                this.gotoAndStop ("Lock");
            if (PuzzleGlobals.pieceActive == true) {
                this.addEventListener(TouchEvent.TOUCH_BEGIN, geoPuzzleBegin);
        public function geoPuzzleBegin (e:TouchEvent): void {
            e.target.addEventListener(TouchEvent.TOUCH_END, geoPuzzleEnd);
            e.target.gotoAndStop("Over");
            MovieClip(this.parent).nameDisplay.gotoAndStop(e.target.abbrev);
        public function geoPuzzleEnd (e:TouchEvent): void {
            if (e.target.isLocked == false) {
                e.target.gotoAndStop("Off");
            else if (e.target.isLocked == true) {
                e.target.gotoAndStop("Lock");
            MovieClip(this.parent).nameDisplay.gotoAndStop(PuzzleGlobals.chosenPuzzle);
            e.target.removeEventListener(TouchEvent.TOUCH_END, geoPuzzleEnd);
You can see that each piece (whether it's already locked on the stage or movable) reacts differently to different touch events. However, this is the code that Adobe gave me as a workaround:
this.stage.addEventListener(TouchEvent.TOUCH_BEGIN, onTouchEvent);
this.stage.addEventListener(TouchEvent.TOUCH_MOVE, onTouchEvent);
this.stage.addEventListener(TouchEvent.TOUCH_END, onTouchEvent);
var beginCount:uint=0;
var moveCount:uint=0;
var endCount:uint=0;
function onTouchEvent(event:TouchEvent):void{
     switch (event.type){
          case TouchEvent.TOUCH_BEGIN:
                         trace("BEGIN")
                         beginCount++;
                         square.x = event.stageX;
                         square.y = event.stageY;
                         square.startTouchDrag(event.touchPointID, false);
                         break;
          case TouchEvent.TOUCH_MOVE:
                         trace("MOVE")
                         moveCount++;
                         break;
          case TouchEvent.TOUCH_END:
                         trace("END")
                         endCount++;
                         square.stopTouchDrag(event.touchPointID);
                         break;
     trace("begin: "+beginCount+" move: "+moveCount+" end: "+endCount);
//     countText.text = "begin: "+beginCount+" move: "+moveCount+" end: "+endCount;

I am going to copy and paste this answer into all of the forums I've asked this question in case some noob like me comes along and needs the answer.
I found the problem! After 3 months I finally figured out what was wrong and why my app was working in Device Central when exported as Flash 10.1 and not on my iPad when exported as AIR for iOS.
The problem is that in the Flash runtime, if a line of code returns a bug, the flash runtime says "Error, shmerror, try again next time." So I had one if, else statement that was executing when it wasn't supposed to be - only once, at the very beginning of the program. It was throwing an error. When I exported as Flash, flash didn't care, and still executed the code later when it was supposed to. But Apple won't let their programs crash. So instead of just trying that code again, Apple decided, after the first error was thrown, that it would then COMPLETELY IGNORE that line of code. So the error was in the line where the states would unhighlight themselves. Apple just shut down that line of code, that's why it wouldn't execute properly.
I ended up changing this line of code
if (lastObjOver != null && lastObjOver.isLocked == true)
which threw an error when the piece was FIRST dragged over the puzzle, to to this
if (lastObjOver.parent != null && lastObjOver.isLocked == true)
which wouldn't throw the error.
Problem solved!
If anyone else is having this problem, I suggest you do what I did. Change all your touch events to mouse events so you can run the program in the adc debugger. That's when I discovered the error being thrown.

How can i raise events from a class?

Hi all, i've a problem with events.. how can in java to raise an event and to catch him?
For example i have ha class Counter like this:
public class Counter
int[] vettore = new int [10];
int vetCnt = 0;
void addNumber(int number)
if (vetCnt < 10)
vettore[vetCnt++] = number;
for(int n=0;n<vetCnt;n++)
System.out.print(vettore[n]);
System.out.println();
else
System.out.println("Vector full!");
The main class is like this:
public class Main
public static void main(String[] args)
Counter cnt = new Counter();
MyEventListener listener;
cnt.addNumber(0);
cnt.addNumber(1);
cnt.addNumber(2);
cnt.addNumber(3);
cnt.addNumber(4);
cnt.addNumber(5);
cnt.addNumber(6);
cnt.addNumber(7);
cnt.addNumber(8);
cnt.addNumber(9);
cnt.addNumber(10);
cnt.addNumber(11);
cnt.addNumber(12);
Now what i i want to raise an event that i can catch in the main class instead of print a message? I know how to do this in C#, but in Java is very different..
Thank you

Correct handling of objects extended from FX classes

Quick simple question. If I write a class that's extended from one of JavaFX's classes, do I need to make state changes that weren't part of the original class on the FX Application thread? In my case, I'm creating a signal class that's basically a Path, but it has some other information that is set by other threads, like the next value that will be added to the path. Obviously, I need to actually do the adding of that value to the Path on the FX Application thread. But if my Signal is extended from path, and I have a nextValue field, and a receiveValue method, would it be safe for me to call receiveValue on another thread? The co-ordinate to add to the path would later be created from that value, on the FX Application thread. Thanks!
-cullam

You can call your own methods from any thread you like. As soon as you interact with properties that would change the Scene however you will have to be on the FX thread.
I extend the JavaFX containers all the time in my project and I'm very happy with how that works out.

JavaScript event from an JApplet

Here is some basic html/javascript that I am starting with:
<table border="2">
<tr id="ex2"><td width="100%" height="300" ><iframe width="100%" height="300" scrolling="no" src="http://www.sun.com"></iframe></td></tr>
</table>
<table width="100%" align="center">
<tr><td><iframe align="center" width="100%" height="300" scrolling="no" name="t1" src="http://www.apache.org/"></iframe></td></tr>
</table>
<script type="text/javascript">
function myi(){
document.all.t1.src='http://www.oracle.com/';
</script>
<form><input type="button" value="click Me" onClick="myi()"></form>
My goal is from an menu within a JApplet to pass the javascript function myi() a URL and cause the function to execute. I'm kind of thinking I may need to use the netscape.javascript package but I am unsure. Any advice would help
Thank you
Ox

If the user has the JRE 1.4 plugin installed, you can use the netscape.javascript plugin very easily. If not, you can use JApplet.getAppletContext.showDocument("javascript:myfunction('some url')", "_self");
This way isn't very stable, though. I had a user apply a patch to IE and this method stopped working.

Java Event from imported class

I have a java program comprising two classes: Alpha and Bravo. Class Alpha contains the main() method. Class Bravo contains a Button that will display a text when pressed. Class Bravo also contains this method:
public boolean action(Event evt, Object obj)
Problem: When I scrap the Bravo class and move the method *"action"* to Alpha, everything works fine. But when the method *"action"* is in Bravo, the text does not display.
ASSUMING I WANT TO USE THE TWO CLASSES ALPHA AND BRAVO; ASSUMING I WAN TO KEEP MAIN() IN ALPHA AND ACTION IN BRAVO: how do I fix this?
Thanks
