Keyboard event capture [CS6]

• Capturing keyboard events?

  How is it possible to listen to keyboard events, as the depressed return key?  I understand the class ReturnKeyType does not yet work for the QNX InputText component, but even when it's that I'm not sure it will include keyboard events or if it will just be a Visual change to the BACKSPACE on the keyboard.

  I intend using the class flash.text.TextField (for portability) instead of qnx.ui.text.InputText.  Currently, the keyboard will activate and disappear the flash.text.TextField receives or loses the focus.  However, these text fields are the fields of data entry, so I would listen to the back of the key on the keyboard so that I may as well save entered data and remove the keyboard of the screen - or perhaps more simply, just leave the text field to listen to when it loses focus to save the data and allow the keyboard to disappear.  But how do I activate either by pressing back on the keyboard?

  Hey David,

  You can achieve this by using a listener to listen to the keys on your input object as a textfield and response following which keys are pressed. in your case you would listen for the Enter key and perform your actions like taking the focus and the keyboard on the screen. You can use the program below as a reference as to how this can be done:

  package
  {
      import flash.display.Sprite;
      import flash.display.StageAlign;
      import flash.display.StageScaleMode;
      import flash.events.KeyboardEvent;
      import flash.text.TextField;
      import flash.text.TextFieldAutoSize;
      import flash.text.TextFieldType;
      import flash.ui.Keyboard;
  
      [SWF(width="1024",height="600",backgroundColor="#CCCCCC",frameRate="30")]
      public class TextFieldTest extends Sprite
      {
  
          private var myInput:TextField;
  
          public function TextFieldTest()
          {
              super();
  
              // support autoOrients
              stage.align = StageAlign.TOP_LEFT;
              stage.scaleMode = StageScaleMode.NO_SCALE;
  
              myInput = new TextField();
              myInput.width = 300;
              myInput.height = 50;
              myInput.type = TextFieldType.INPUT;
  
              /*
               * listen for what keys are being pressed and react with
               * onKeyDown function
              */
              myInput.addEventListener(KeyboardEvent.KEY_DOWN, onKeyDown);
  
              addChild(myInput);
  
          }
          private function onKeyDown(e:KeyboardEvent):void
          {
              /*
               * You can listen for any key presses under the
               * flash.ui.Keyboard class. it has all the constants
               * such as .ENTER, .END, etc
              */
              if (e.keyCode == Keyboard.ENTER)
              {
                  trace("You just entered");
  
                  /*
                   * Steal focus away from the textfield object
                   * focus can be set to anywhere and the keyboard
                   * will disappear
                  */
  
                  stage.focus = null;
  
                  /*
                   * Perform other actions such as saving data
                  */
              }
          }
  
      }
  }
  

  hope that helps. Good luck!

• Keyboard events can be captured by our plugins?

  My plugin runs through the paths of PDEPage and the elements, placing those surrounded by the classic rubberband rectangle in the Windows Clipboard. In short, it implements the copy half an installation "copy / paste".

  Sometimes, the user may choose to type Ctrl-A to select a maximum rectangle.

  Is this possible? How?

  TIA

  If you have a custom tool is active, your tool can register for keyboard events.

• Specific keyboard events

  Hi all

  I read a post showing how to display and hide the keyboard, then I could listen to type by hiding a textbox behind the keyboard.

  However, I can't seem to find a way to listen to, as when a user presses the BACKSPACE on the keyboard of the playbook, I would be eternally grateful if someone knows a way that I am at a loss.

  Concerning

  Try this:

  this.mytext.textField.addEventListener( KeyboardEvent.KEY_UP, KeyUp );
  

  ////////////////////////////////////////////////////////////////////////
  private function KeyUp( event : KeyboardEvent ) : void
  {
      if( event.keyCode == Keyboard.BACK) // capture enter key
      {
          // do something
      }
  }
  

• Sniff for PrintScreen. In Windows 8 blocked keyboard events, monitor what task is to the point.

  In God we trust.

  Good day, everyone.

  My application designed to block the screen capture. It is based on the events of keyboard hook.

  In Windows 8 my callback function is not called, when the monitor of the task is in short.

  I save my callback function with:

  lowLevelKybdHook_ = SetWindowsHookEx ( WH_KEYBOARD_LL, (HOOKPROC): MyCallbackFunction, hInstance, 0);

  It works perfectly in Windows 7 for all cases.

  Windows 8:

  -He works when the monitor of the task is not open.

  -It works, when Task Monitor is opened, not to the point.

  -It does NOT works when the monitor task in short, i.e. my callback function is not called when the task to monitor is the currently selected window.

  -Continue to work (to be called), when the monitor of the task is not to the point.

  I tried to use RegisterHotKey instead SetWindowsHookEx, it has the same effect.

  Any idea?

  Thank you in advance,

  Israel

  PS: I see the same effect with Microsoft Spy ++.
  Keyboard events are blocked, when Microsoft Spy ++ open and in focus.

• Global keyboard event listener?

  Is it possible to create a global keyboard event listener that is unrelated to a window, button, or other user interface element?  The best I could get to add the event to the window listener.  This only works if the window is active.  If the user clicks outside the window and then the receiver for the keyboard does not work.  In addition, when the dialog box appears first of all, it won't work until after the user has made some type of interaction with the window.  I want is to have keyboard shortcuts for users that work regardless of the place where they clicked on the screen, even if the dialogue window is not 'active'.  Is this possible?

  Here is the code I use to the receiver of keyboard for the window.

  mywindow.addEventListener ("keydown", function (k) {keyListen(k)});
  function keyListen(k){if(k.keyName=="Z"){alert("Do stuff here");}}
  

  I don't think that you can create listeners of world events, as for the first appearance of the dialog box, I solved this problem in my script: scripts buliarca BCM_ExtendShortcuts UI by a button activates the event listener to this button. A problem with attach listeners to window, it's in CC2015 events can only be attached to controls and not windows. Setting for windows works in CS6...

  You use the incorrect event. Change to applicationComplete creationComplete and it will work.

• Unforeseen event, captured by the structure of the digital change notification event

  Using the specific or similar to http://decibel.ni.com/content/docs/DOC-2280 code (change digital notification.vi) I'm observing behavior unexpected, but coherent structure of the event. The structure of the event capture an event, the first time data is received in the structure of the event; even if there was no change in the digital port assigned. After this initial unexpected event, the structure of the event behaves as expected.

  I just wanted to know if someone had a glimpse of it. What is the task of detection of change this event to initialize?

  In this case, you would have to ignore the event first, which in my opnion is valid because it reserve no value to a value.

• Keyboard event handler

  I want to process keyboard events and execute a method on every key stroke. It works, but the value sent is a character behind what is actually typed

  < af:resource type = "javascript" >

  function doSomething (evt) {}

  var _keyCode = evt.getKeyCode ();

  model var = evt.getSource ();

  Alert (COMP.getSubmittedValue ())

  AdfCustomEvent.queue (comp, "KeyboardEvent",

  {

  FValue: comp.getSubmittedValue)

  },

  (false);

  evt. Cancel();

  }

  < / af:resource >

  < af:inputText label = "Label 1" id = "it1' autoSubmit ="true">

  < af:clientListener type = "keyPress" method = "doSomething" / >

  < af:serverListener type = "KeyboardEvent" method="#{pageFlowScope.myBean.handleKeyboardEvent}"/ >

  < / af:inputText >

  So, if I type

  ADF

  The first time I will get an empty string, the second time 'a' and the last time "ad".

  Is there a way to get the current value?

  JDev 11.1.2.4

  My work now code I used the keyPressed instead of keyUp event. So now, getSubmittedValue returns the correct value.

  I can't use autosuggest because what the user types is not the value that is to be submitted. For example, the user is looking for a phone country code, it will start to type Ger and the suggested value is Germany + 49 but the value which should be in the form is + 49 and not Germany + 49.

• If (child on screen) AS3 {play child} (keyboard.event)

  Maby someone can help me with this? :

  I have this script:

  var answerA:Array = [];

  function answerF(answerS:String,x:int,y:int,space:int):void {}

  stiff var: int = answerS.length;

  Word of the var: int;

  If ((answerS.length % 2) == 0) {}

  Word = (((raides * 150) + ((raides-1) * space)) / 2-150);

  } else {}

  Word = (((raides-1) * 150) + ((raides-1) * space)) / 2) - 75;

  }

  var nextX:int = x - Word;

  var C: Class;

  var letter: MovieClip;

  for (var i: int = 0; i < answerS.length; i ++) {}

  C = Class (getDefinitionByName (answerS.charAt (i)));

  Letter = new C();

  addChild (letter);

  answerA.push (letter);

  letter.x = nextX;

  letter.y = y;

  nextX += letter.width + space;

  }

  }

  On the library, I have objects whose names A, B, C, D, E, f... to Z

  This script adds letters from the library. With this script all ok it works perfectly for me, but I want keyboard event for each letter to play but now I don't know how to do this.

  
  

  I have a script:

  
  

  stage.addEventListener (KeyboardEvent.KEY_DOWN, AKeyDown);

  function AKeyDown(event:KeyboardEvent):void {}

  If (event.keyCode == Keyboard.A) {}

  A.Play ();

  }

  }

  This script works then object instance name.

  And I want to do:

  stage.addEventListener (KeyboardEvent.KEY_DOWN, AKeyDown);

  function AKeyDown(event:KeyboardEvent):void {}

  If (event.keyCode == Keyboard.A) {}

  If child with class name an exist on screen}

  playing the object with the name of class A

  
  

  } else {}

  var erreur.r: Sound = new eror();

  errorR.play (0, 1);

  }

  }

  }

  What you need to do, is to give each child a name as you load them.  Then, you can target with their name property.

  var C: Class;

  var letter: MovieClip;

  for (var i: int = 0; i<>

  C = Class (getDefinitionByName (answerS.charAt (i)));

  Letter = new C();

  letter. Name = answerS.charAt (i);

  addChild (letter);

  answerA.push (letter);

  letter.x = nextX;

  letter.y = y;

  nextX += letter.width + space;

  }

  }

  stage.addEventListener (KeyboardEvent.KEY_DOWN, AKeyDown);

  function AKeyDown(event:KeyboardEvent):void {}

  trace ("key pressed:" + string.fromCharCode(0)) (event.charCode));
  var ltr:MovieClip = MovieClip (getChildByName (string.fromCharCode(0)) (event.charCode)));
  LTR. Play();

  }

  You will probably need to convert the string.fromCharCode(0)) (event.charCode) uppercase if you are naming them with capital letters.

• sequence of images, add the keyboard event loop?

  Hi all

  I have a sequence of 3d images that I want to run with the mouse and drag.

  So far I succeeded with that.

  Also added keyboard event.

  Else if (event.keyCode == 37)

  }
  }

  I tried looping event, that is, playing continuously until the button is pressed.

  Help, please.

  Thanks in advance.

  function keyPressed(event:KeyboardEvent):void

  {

  If (event.keyCode is 39)

  I think that to have public but do not know how the value Keyboard.Event.LEFT, UP, DOWN, RIGHT.

  import flash.events.KeyboardEvent;

  stage.addEventListener (KeyboardEvent.LEFT, characterMove);

  stage.addEventListener (KeyboardEvent.DOWN, characterMove); ------Headphones of events for left keyboard etc.

  stage.addEventListener (KeyboardEvent.UP, characterMove);

  stage.addEventListener (KeyboardEvent.RIGHT, characterMove);

  new audience; function characterMove(evt:KeyboardEvent):void {------function to move the person}

  Switch (evt.keyCode) {}

  case Keyboard.LEFT:

  Person.x-= 20;

  case Keyboard.RIGHT:

  Person.x += 20;

  case Keyboard.DOWN:

  Person.y-= 20;

  case Keyboard.UP:

  Person.y += 20;

  by default:

  trace ("keyboard event error")

  }

  }

  Your listeners must specify KeyboardEvents and upward, DOWN, LEFT, RIGHT aren't KeyboardEvents, they are key keyboard codes.  Using KEY_UP and KEY_DOWN instead of each of them in the headphones.
