• touchevent is getrated every time I click on the screen of the blackberry java

  Hello friends,

  I am from the substitution of toucheven like this:

  Ematics bitmap = Bitmap.getBitmapResource ("onlbswth. PNG');

  Break of bitmap = Bitmap.getBitmapResource ("offldswtch. PNG');

  BitmapField switchOffField = BitmapField (switchOff) new

  {

  protected boolean touchEvent (TouchEvent message)

  {/ / TODO self-generated method stub}

  If (TouchEvent.GESTURE == message.getEvent ())

  {if(flag==0)

  {flag = 1;

  switchOffField.setBitmap (switchOn);

  } else

  {

  flag = 0;

  switchOffField.setBitmap (switchOff);

  }

  }

  Returns true;

  }

  };

  Once I click on bitmapfield, the event is genrated... next time whenever I click on screen event is again genrated...

  is there anything to add to this

  Here's some code I've used processes click on events.  It will be useful.

  protected boolean touchEvent (TouchEvent message) {}
  int x = message.getX (1);
  int y = message.getY (1);
  If (x < 0="" ||="" y=""> < 0="" ||="" x=""> getExtent () .width: y > getExtent () .height) {}
  Outside the scope
  Returns false;
  }
  Switch (message.getEvent ()) {}
  case TouchEvent.CLICK:
  button click (0);
  Returns true;
  }
  Return super.touchEvent (message);
  }

• BlackBerry Storm - problems with touchEvent

  Hi all

  I'm porting a game of BB to the storm.

  I've added a handler for the touchEvent, like this:

  protected boolean touchEvent (TouchEvent message)
  {

  regardless of the code

  Returns true;
  }

  The problem is that the method is called, but GetX (1), GetY (1) always are-1 and message.getEvent always returns 0, no matter if the screen is clicked/typed.

  Any ideas?

  Thank you.

  touchEvent must be replaced each time you need manage key events.

• Interactive GaugeField on the BlackBerry Storm

  I just tried to create a modifiable on my BlackBerry Storm GaugeField, I used the constant can be CHANGED and made sure that there is enough space to select. It does not work, an interactive GaugeField only works on devices touch non-ecran?

  If so someone changed the GaugeField so it will work on a touchscreen device?

  Otherwise what could I do it wrong?

  I realized thinking about how it would be possible to make this is interactive and realized that as a last before amending the TouchEvent code should try to make the active gauge because it does not seem to focus. Added Field.FOCUSABLE and it worked.

• Storm - how MIDP canvas can capture Screeen.touchEvent (message TouchEvent)?

  Hi all

  I tried to capture TouchEvent.CLICK with an application that uses the MIDP canvas: alias for the end user by pressing the touch screen - notice I am referring to the same 'click' which occurs when the user selects the "Browser" icon in the main screen and pushes down the entire screen to make it click.

  I can receive and process all the pointer events from MIDP perfectly (pointerPressed, pointerReleased and pointerDragged).

  In the past, we were able to capture the special keys by using the following:

  class AppCanvas extends Canvas implemens TrackwheelListener, {KeyListener

  public AppCanvas() {}

  ...

  If (Ui.getUiEngine () .getActiveScreen ()! = null) {}
  Ui.getUiEngine () .getActiveScreen () .addTrackwheelListener (this);
  Ui.getUiEngine () .getActiveScreen () .addKeyListener (this);
  }
  }

  {} public boolean touchEvent (TouchEvent msg)

  is never called

  ...

  }

  Canvas.keyPressed and keyReleased would get a few keys, so that the listeners TrackwheelListener and KeyListener would get others.

  However, it seems like there is no way to make it Screen.touchEvent (message TouchEvent) except if you extend the Screen class, which is something that we do not expect to do - since our application uses MIDP canvas.

  Here's the main problem in terms of feeling of native BB app and midlet:

  A storm for the end user would expect that touching a UI widget will assign the focus but who would NOT fire the action of this widget. Instead, the end user expects that the action of this widget would fire when the widget is "clicked".

  Obviously, there is no way to tell a 'touch' of a "clicked" using canvas MIDP pointer-events.

  Any suggestions?

  Thank you

  I come to know BlackBerryCanvas of this thread:

  Why a Midlet would have problems using TrackwheelListener?

• Class 'net.rim.device.api.ui.TouchEvent' not found

  I built the demo using the JDE 4.7.0.41 TicTacToeDemo application and tested using the simmulator without problem. Also, I do not change a signle code line.

  I also loaded on my phone, and when you start it on my phone, I got the following error:

  Error Starting TicTacToeDemo: Class 'net.rim.device.api.ui.TouchEvent' not found

  No idea why this error?

  You are right.  The version of the BlackBerry JDE must be equal or lower than the software version of terminal Blackberry target.  The following link explains it further.

• CustomListField + CustomButtonField + touchEvent + NavigationClick is HELL

  Hello world

  I'm doing this thing works

  I have a screen which consists of three components

  HEADER

  -a custom refresh button (extends the scope with a bitmap and override touchEvent and navigationClick)

  CONTENT

  -NavigationClick and custom touchEvent ListField and substitution

  FOOTER

  -Type of a menu with several button (application as well as for the header)

  When I run my screen, the focus is made on the footer, so I can use my buttons

  If I click on the listField or even make dragging, then the listField component get the Focus.

  Now, when I touch one of my footer button, only the method of the ListField touchEvent's launch, even if I return false in everycase, neither the toucheEvent nor my footer buttons navigationClick method will be called.

  So if I click on my footer, I see only the listField slips a little and nothing else.

  Anyone experienced the same thing?

  This BlackBerry bug has already been reported and confirmed by RIM on this forum:

  ListField scrolling behind other fields

  So no, you're not crazy, and no, you do not have something wrong.  I hope it's a consolation

• Solution to the problem of the touchEvent and click

  Hi all

  Finally I found the solution to touchEvent and click on the question discussed here

  http://supportforums.BlackBerry.com/T5/Java-development/problem-with-touchEvent-and-click/TD-p/58671...

  I put my code based on navigationClick and also said a function void touchEvent() as shown below

  protected boolean navigationClick (int status, int time) {}

  code click event

  }

  protected boolean touchEvent (TouchEvent event) {}

  }

  Now I can easily detect a touch event on any area on my screen

  Don't know how it works, but I'm getting the desired output

• TouchEvent exception on vary basic app (9550 sim)

  I have recently interested in programming again and decided to start with the programming of blackberry. I get errors immediately the bat which is not encouraging, but I was hoping someone could help me.

  I created a basic "Getting Started"-based application first tutorial app. I added then added a button and a listener of field for this button that displays an alert dialog box. Very simple, but in my Simulator (9550) I get a runtime exception which stops at "TouchEventInternal.getGlobalX (int). This happens when I click 'OK' on the alert dialog.

  Any help or advice would be appreciated

  Micah_H Hey!

  I guess you need to access the UI event handling, since it seems that you are outdoors. For example, you can use invokeLater () methods or invokeAndWait ().

  UiApplication.getUiApplication().invokeLater(new Runnable(){
      public void run() {
          Dialog.alert("YOU PUSHED A BUTTON");
      }
  });
  

  The other alternative is to set the CONSUME_CLICK function to your button:

  ButtonField button = new ButtonField("Add New", ButtonField.CONSUME_CLICK);
  

  Anyway, honestly, I surprised when your code works on previous 9530 Simulator. I don't know why!

  Kind regards

• BlackBerry 9900 touch event not firing

  Hey,.

  I am new to the BlackBerry development and need help. I use a BlackBerry 9900 to test.

  I have a single screen in my application that has several buttons. It reacts to the touch of the events if the button is highlighted.

  Here is my code:

  HorizontalFieldManager hfmRow = new HorizontalFieldManager();
  
  _firstButton = new ButtonField("First");
  _secondButton = new ButtonField("Second");
  _thirdButton = new ButtonField("Third");
  _fourthButton = new ButtonField("Fourth");
  _fifthButton = new ButtonField("Fifth");    
  
  hfmRow.add(_firstButton);
  hfmRow.add(_secondButton);
  hfmRow.add(_thirdButton);
  hfmRow.add(_fourthButton);
  
  add(hfmRow);
  add(_fifthRow);
  

  Try the following - replace / / perform a treatment with what you want on click

  _firstButton = new ButtonField("First"); _secondButton = new ButtonField("Second"); _thirdButton = new ButtonField("Third"); _fourthButton = new ButtonField("Fourth"); _fifthButton = new ButtonField("Fifth");
  
  HorizontalFieldManager hfmRow = new HorizontalFieldManager(){protected boolean touchEvent(TouchEvent message) {        int x = message.getX(1);        int y = message.getY(1); if (_firstButton.getExtent().contains(x, y)) {          //Do processing          return true;}else if (_secondButton.getExtent().contains(x, y)) {          //Do processing          return true;}else if (_thirdButton.getExtent().contains(x, y)) {          //Do processing          return true;}else if (_fourthButton.getExtent().contains(x, y)) {          //Do processing          return true;}else if (_fifthButton.getExtent().contains(x, y)) {          //Do processing          return true;}else{ return super.touchEvent(message);}}}; hfmRow.add(_firstButton); hfmRow.add(_secondButton); hfmRow.add(_thirdButton); hfmRow.add(_fourthButton);hfmRow.add(_fifthButton); add(hfmRow); add(_fifthRow);
  

• cannot find the symbol: class TouchEvent

  Hello.

  I want my application to respont to some touchgestures (SWIPE_EAST and SWIPE_WEST for now...)

  I found a great example on how this right here: http://na.blackberry.com/eng/deliverables/5820/Respond_to_a_slide_down_motion_508152_11.jsp

  The problem is, that the need to import classes do not work for me...

  // Gesture handling
  import net.rim.device.api.ui.TouchEvent;
  import net.rim.device.api.ui.TouchGesture;
  

  results in the error:

  cannot find symbol
  symbol: class TouchEvent
  Location: package net.rim.device.api.ui
  Import net.rim.device.api.ui.TouchEvent;

  what I'm doing wrong here?

  You didn't mention what version of the JDE. TouchEvent only appears in JDE 4.7. If you try to use an earlier version, then you will get this error.

• iTunes and Blackberry link conflicts

  Hi, link to Blackberry stopped working after the last update of iTunes in Windows 10.

  I made Blackberry suggest workaround solution, as follows:

  "Rename the file of l iTunesPrefs.xmand restart the BlackBerry link application.

  Please note: Completing the steps below may have harmful effects on the functionality of iTunes. For more information, contact Apple support.

  To rename the iTunesPrefs.xml;

  1. Turn on the Show hidden folders and files
  2. Go to \AppData\Roaming\Apple Computer\iTunes\ < username > C:\Users\
  3. The XML in the file iTunesPrefs and rename it to iTunesPrefs.old

  Once finished, he recommends to disable display the hidden files and folders. »

  
  

  My question is, how will this affect iTunes functionality, or not at all?

  
  

  
  

  Rename iTunesPrefs.xml will reset various settings in iTunes. If your library is < user music > \iTunes default path and you have the options to keep... and copy... enabled, you may not notice a change, but the parameters that will have been reset include the active library, media folder file, sharing of XML, the import settings, etc. Check through each tab in Edit > Preferences to see if there's anything to change the way that you had it before.
