3D keyboard Events

I am looking into keyboard actions in 3D. Are keyboard actions implemented the same way as 2D using the implements KeyListener?
For example press arrows to move a character
Thanks

Wow, that's great, thanks. I don't understand why nobody else
could tell me that. Here's what I really need to know: when the
script detects the user pressing Enter (for example), how can I
maximize the screen (not full-screen)? Ctrl + F doesn't seem to
work in the player, even though it's listed in the menu, though
clicking the menu item does work.
And when the script traps the Esc key, how can that restore
the window? Once the player with the FLVplayback component goes
full-screen, no keystroke or mouse click will restore or close it.
I have to use Task Manager to abort it.
FWIW, I can do this to go in and out of full-screen:

Flex 4 does not dispatch keyboard events for ENTER key.

Hello everyone. I think I have a strange problem with Flex 4 Beta (4.0.0.8909). My application has had event listener for keyUp event for a month now and suddenly (two days ago) I've noticed that keyUp event is not dispatched for ENTER (ALT also) key. Anyone know why? By the way, I've tried this with keyDown event, also 4.0.0.8847 version of SDK - still the same: no keyboard events for ENTER (and ALT) key.
Here is the sample application that has got this issue:
<s:Application
   xmlns:fx="http://ns.adobe.com/mxml/2009"
   xmlns:s="library://ns.adobe.com/flex/spark"
   xmlns:mx="library://ns.adobe.com/flex/halo"
   minWidth="640" minHeight="480"
   keyUp="application1_keyUpHandler (event)">
   <fx:Script>
      <![CDATA[
         import mx.controls.Alert;
         protected function application1_keyUpHandler (event: KeyboardEvent):void
            Alert.show ("Key up: " + event.keyCode);
      ]]>
   </fx:Script>
   <s:layout>
      <s:BasicLayout/>
   </s:layout>
   <s:TextArea verticalCenter="0" horizontalCenter="0" width="200"/>
</s:Application>
If you run this application and try typing anything in a TextArea you will get alerts with key codes. However, if you press ENTER (or ALT), you will get no alert.
I'm pretty sure the code above is right so that means there is a bug in latest nightly builds of SDK (i would swhitch to an older build if i knew which one does not have this bug).
Any ideas?

That's true, but in this case, I think the text editing code is eating ENTER key in order to prevent parents from seeing it and acting on it (like a submit button). We'll see if we can find a way around that.
You can get the ENTER key now by listening in capture phase.

The enter key isn't being disposed of by textedit, the attached example code works without error if you a- remove the alert box and b-set the focus to your text area on initialisation. I agree that pressing the enter key then calling a dialog box will result in the enter key being "gobbled up" as the enter key is overridden by the dialog box code.
I think the first suggestion should be to anyone don't use dialogboxes for testing code. If for some reason debugging isn't desirable instead of a trace statement a simple label can be used as a 'fake' trace.

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.

Disablying keyboard events in a JFrame.

Hello,
How is it possible to disable keyboard events for a specific JFrame and then (after a while) enable events again ?
thank you,

Look at this program, events are send but you can't see the data in the fields.

import java.awt.event.*;

               dispose();
               System.exit(0);
     setLayout(new GridLayout(4,0));
     add(new TextField("this is a text field"));
     add(new TextArea("this is a text area"));
     add(new Button("this is a button"));

In Flashplayer, I can crossover mouse and keyboard events. In IrfanView I cannot. Can this be fixed?

My client uses IrfanView to play SWF files. Unfortunately, he does not use Flashplayer. In Flashplayer, I can crossover mouse and keyboard events with no problem. In IrfanView, the second I click a button, the keyboard events are disabled. Is there a fix?

Hi Ned. I may have posted this issue a bit early, but this problem is also happening in Flashplayer 10. It's not exclusive to IrfanView.
Here is something that I encountered during my testing, when I jump to scene 6 using the menu button, I have a play button to jump from one frame to the next frame that stops -- the keyboard events start working. But if all I am doing is jumping scene to scene with the mouse button, the keyboard events are disabled.
I feel as if the keyboard events only work if I am playing frames in the scene. And if all I am doing is jumping scene to scene using the buttons, the keys will disable.
I set up the mouse buttons inside a movieclip that all the scenes share. The mouse actionscript is in the movieclip. On the main timeline of each scene is an actionscript for the keyboard events, even though I had to change each function name.
I feel the actionscript is setup pretty simple. I just wish clicking the buttons would not disable the keyboard events. This may sound redundant, but the keyboard events do the same thing if you use the mouse buttons. It's just preference for the client even though he will need to understand that using the mouse buttons override the keyboard events. He doesn't really lose functionality.
Keyboard actionscripting below:
import flash.events.KeyboardEvent;
stage.addEventListener(KeyboardEvent.KEY_DOWN, onKeyEvent);
function onKeyEvent(e:KeyboardEvent):void {
var character:String=String.fromCharCode(e.charCode);
if (e.keyCode==72) {
gotoAndStop(1,"master");
if (e.charCode==49) {
gotoAndPlay(1,"Distributor");
if (e.charCode==50) {
gotoAndPlay(1,"Mirka");
if (e.charCode==51) {
gotoAndPlay(1,"Farm");
if (e.charCode==52) {
gotoAndPlay(1,"Check2");
if (e.charCode==53) {
gotoAndPlay(1,"Check3");
if (e.charCode==54) {
gotoAndPlay(1,"Scene2");
if (e.charCode==55) {
gotoAndPlay(1,"Scene1");

Can we catch keyboard event triggered by an inputfiled?

Hi all,
I have a question here:
When we are doing the web dynpro abap development, if I want to catch the keyboard triggered by an
input help and handle it, how can I achieve this?
e.g. I have an inputfield on the UI, if user click "F10" on the keyboard, can I catch this kind of event?
Thanks and Regards,
Aaron

Hi Thomas,
Yes, I'm trying to acomplish an input help for an inputfield.But, the free programmed value or OVS or dictionary search help can fullfill my needs.Here is the situation:
I have a inputfield on the UI, and next to that , I have another textview, which should be changed according inputfield. e.g. the inputfield is a user name, and next to that , is the user id. but we only want the input help for user name. so when user select one row iof the search result table, I want that two fields both filled.
1. the OVS can't meet my need because I can't change the layout of the search result table, I need a table with a tree in it.
2. free programmed value help can only send back the value of the inputfield. although maybe I can get the user_id's context attribute name and by hardcoding and send back also the user id. but I don't like hardcoding.
So, I'm wondering whether I could catch the keyboard event. and handle the F4 help all by myself.
Do you have some suggestion on this?
Thanks and Regards,
Aaron

Getting keyboard events on ALV grid

Hi,
I have an ALV Grid where it is possible to edit data. If user selects a row and presses delete/cut button with mouse event is triggered and I can access those events in code. Although if user selects a row and presses "Del" or "Ctrl + X" then I can't access those events in code. Is there a way to access keyboard events inside my code?

Have a look at BCALV_GRID_EDIT -> if you select the first checkbox (p_cell = Update on cell change) then you will find that "data_changed" event can catch the line deletion via the keystrokes described.. in the event in this program, you could get the rows deleted from "rr_data_changed->mt_deleted_rows".
if p_cell = 'X'.
call method grid1->register_edit_event
exporting
i_event_id = cl_gui_alv_grid=>mc_evt_modified.
else.

[solved] send keyboard event / key to specific background window?

Hi!
So... is this possible / how? I'd like to send keyboard events to a window in the background - maybe even in regular intervals. While I'm dong something else, in another window (or nothing).
Thx!

Actually I'm thinking, maybe there is a totally another (better?) way to do what you want. I usually find that automatizing tasks in linux differs very much from the windows experinece, most of the times scripting is the most powerful and easy way of doing things. So if you describe to us what you want to accomplish, maybe some experienced linux gurus would give you some advices that sets you off course from sending keys and mouse events. I used to do that in windows with autohotkey, but now in linux there was no need for that so far ever, except for using system wide abbreviations with autokey.

Handling keyboard events in applets?! Possible?!

Hello,
I wrote a little game that uses keyboard handling events. It is an applet that can also standalone as an application. When i run the program as a standalone application, it handles keyboard inputs fine. ie...i can press the left and right arrow keys and something happens.
But when i run my program as an applet in a web browser, the applet starts up correctly but does not handle any keyboard events. It only handles mouse events. For instance, if i press the up and down arrow keys, the browser window scrolls up and down!!! And the up and down arrow keys have a specific purpose in my applet.
QUESTION: how do i get my applet to accept keyboard inputs such as UP,DOWN, LEFT, RIGHT?

Hmm something went wrong w/ my post so i hope this doesnt show up twice.
Hey thanks a lot for helping me out. The applet/application is large so here is the main() method and the keyboard event handling class code. My question is how come the keyboard events get properly handled when i run it as a standalone application, but keyboard events go to the browser when i run it as an applet? I would post my entire code but it's over 1000 lines and spread out over 8 files. hehehe.
Here is main():
public static void main(String[] args)
      MyProgram applet = new MyProgram();
      applet.isStandalone = true;
      JFrame frame = new JFrame();
      frame.setTitle("Physics: Kinematics");
      frame.getContentPane().add(applet, BorderLayout.CENTER);
      applet.init();                        // initialize the applet inside frame
      applet.addKeyListener(kbHandler);     // kbHandler is a keyboard handling object
      applet.start();
      frame.setSize(APPLETWIDTH,APPLETHEIGHT);
      Dimension d = Toolkit.getDefaultToolkit().getScreenSize();
      frame.setLocation((d.width - frame.getSize().width) / 2, (d.height - frame.getSize().height) / 2);
      frame.setVisible(true);
      // private inner class to terminate the Application when frame closes
      frame.addWindowListener(
        new WindowAdapter()
            public void windowClosing(WindowEvent e)
                System.exit(0);
      frame.show();
   }"kbHandler" is the keyboard event handling object. It gets initialized in the applet.init() method.
kbHandler = new BMkeyboardHandler();And here is the keyboard event handling code:
// ===== keyboard event handler ===========
   private class BMkeyboardHandler implements KeyListener
        public void keyPressed(KeyEvent e)
            pushedKey = e.getKeyCode();
            // General administrative key actions
            if(pushedKey == KE.VK_H)
                actionArea.toggleHelpMenu();
                actionArea.repaint();
            else if(pushedKey == KE.VK_C)
                actionArea.toggleCtrlMenu();
                actionArea.repaint();
     }So there it is. Again, the program handles events fine as a standalone application. But running it as an applet in a browser (and even the appletviewer) doesnt let me handle keystrokes.

Detect mouse clicks or keyboard events on desktop or everywhere

Hi,
What I have to do is to start the application minimized in the system tray. Then the application must be listening for crtl+shift+left mouse click in any part of the desktop or an opened application, when that happens, I have to show a window asking if the user want to take a screenshot starting in the x,y point he clicked and then take the screenshot.
What I don't know how to do is to detect the mouse and keyboard events when the application is supposed to be running minimized in the system tray.
How can I do that? Can anybody give me a hint?
Thanks in advance.

It's not possible with plain Java. You will need native code for this. Take a look at JNA.

Listen Keyboard events in AIR for iOS? [HELP]

It works in the browser... Is there any way in AIR to do this for iOS ?

Hi, this is an old post but it is related to issues that still in Adobe AIR 3.7, I have the same situation implementing an iCade controller, I have solved the problem creating an iCade proxy that use a hidden TextField to capture text change events that are mapped into keyboard events and finally dispatched to the game listener. This is the code so far, it works but is not optimized, im sure you can optimize and remove the useless code from here:
package {
          import flash.display.DisplayObjectContainer;
          import flash.display.FocusDirection;

I have a new MacbookPro (October 2011, MacBookPro8,2) with 4Gb RAM running latest 10.6.8, and I am extremely frustrated by periodic loss of mouse events (movement freezes, then jumps) and keyboard events (loss of keystrokes) whenever a sound alert is made. Am I the only person experiencing this?

I should also add a related behavior, repeated keypresses. I do a lot of work on connected unix/linux machines using terminal. Sometimes I will be navigating directories and hit <tab> for command completion, and unexpectedly get the screen scrolling as if I had typed it 100 times!

Help with Keyboard Event

Hi, I am designing a drum machine in flash pro Cs6 actionscript 3.0 and I am trying to add a keyboard event that will trigger a button event that I have all ready created, I can create the event to play the sound but this is not what I want, can I call the click event so the button will move on the key event triggering the sound, here is an example of one of my buttons code... btn, thank you if anyone can help.
import flash.events.KeyboardEvent;
playsound2.fla
playsound with extra functionality:
textbox added.
Displays ID3 info of the sound
btn.addEventListener(MouseEvent.CLICK, playSomeSound);
function playSomeSound(e:MouseEvent)
          var req:URLRequest = new URLRequest("Savage.mp3");
          var s:Sound = new Sound(req);
          s.addEventListener(Event.COMPLETE, onSoundLoaded);
          s.addEventListener(Event.ID3, onID3Info);
function onSoundLoaded(event:Event):void
          var localSound:Sound = event.target as Sound;
          localSound.play();
function onID3Info(e:Event):void
          var id3Props:ID3Info = e.target.id3;
          var sOut:String = txt.text = "";
          for (var propName:String in id3Props)
                    sOut = propName + "=" + id3Props[propName] + "\n";
                    trace(sOut);
                    txt.appendText(sOut);
          txt.text = id3Props.comment;
var ba:ByteArray = new ByteArray();
var gr:Sprite = new Sprite();
gr.x = 5;
gr.y = 50;
addChild(gr);
var time:Timer = new Timer(50);
time.addEventListener(TimerEvent.TIMER, timerHandler);
time.start();
function timerHandler(event:TimerEvent):void
          SoundMixer.computeSpectrum(ba, false);
          var i:int;
          gr.graphics.clear();
          gr.graphics.lineStyle(2, 0xFF0000);
          gr.graphics.beginFill(0x00ff00);
          gr.graphics.moveTo(10, 10);
          // draw a circle.;
          var w:uint = 15;
          for (i=0; i<512; i+=w)
                    var t:Number = ba.readFloat();
                    var n:Number = (t * 200);
                    gr.graphics.drawCircle(i, 0, -n);

Thanks, this was the code I added in the end and it works nicely, It covers my sound and id3 aswell as Im displaying lcd text in a dynamic text box.
stage.addEventListener(KeyboardEvent.KEY_DOWN, btndownKey);
function btndownKey(event:KeyboardEvent)
          if (event.keyCode == 83)
                    var url:String = "Savage.mp3";
                    var request:URLRequest = new URLRequest(url);
                    var s:Sound = new Sound();
                    s.addEventListener(Event.COMPLETE, completeHandler);
                    s.addEventListener(Event.ID3, onID3Info);
                    s.load(request);

Capture All Mouse and Keyboard events even if java window NOT in FOCUS

Hi All,
Is this possible to capture all mouse and keyboard events even if java window is not in focus or is minimized. This java program should cature each and every event from the user once the program is started. Any help in this regard is appreciated!
Thanks&Regards
Sam

I don't think you can. (without JNI)

More explanation about Keyboard Events

Someone can help me giving me more explanation about how to use Keyboard events inside a textFlow...
Or maybe show me some example, I try to do something like detect which key is pressed in textFlow.
I read about: keyDownHandler and manageTabKey, but I still without a clear idea...
Can you give me a hand please...?

To filter the keys I'd suggest subclassing ContainerController and overriding keyDownHandler.
Another approach would be to add your own listeners to the containers and call preventDefault to cancel the event.
manageTabKey lets you tell TLF to treat a TAB as an insert of a TAB character and to call preventDefault. Unfortunately that doesn't always prevent the browser from also handling TAB. Not a problem in an AIR App though.
Hope that helps,

Disable datagrid keyboard events

Is it possible to disable keyboard events or prevent the datagrid from switching selected rows? In my app, I allow the user to select a datagrid row, but when they do I make a request to get data. While I am waiting for the data to return I want to prevent the user from using the keyboard arrow keys to select another row.
I have tried setting selectable to false and setting focusEnabled to false, but neither one works. Anyone know of another alternative?
TIA

Block the keyDown event or override moveSelectionVertically
