• several checkbox in horizontalfieldmanager problem!

  Hi, I add several checkbox in horizontal fieldmanager.

  It displays as intended for os 5 and less but only displays the first box added to os 6.

  I don't know what the problem is! Please tell me what I'm doing wrong, or give me a work-around!

  Code:

  check1 = new CheckboxField("1", true);
  check2 = new CheckboxField("2", true);
  check3 = new CheckboxField("3", true);
  
  checkField = new HorizontalFieldManager();
  
  checkField.add(check1);
  checkField.add(check2);
  checkField.add(check3);
  
  add(checkField);
  

  Thanks in advance!

  It seems that in CheckboxField became "width-hungry" the OS 6.  Check this thread for the solution:

• Development/unfocus HorizontalFieldManager problem

  I do this on a HorizontalFieldManager to focus and unfocus color and his works fine. But my doubt is that even if I do my style of hfm like NON_FOCUSABLE, it always shows the unfocus color focus which shudnt be the case. Kindly help

• Custom HorizontalFieldManager problem focusable

  I had a VerticalFieldManager with a list of items.

  Each element is a HorizontalFieldManager custom, composed by other fields. These custom fields are FOCUSABLE by manufacturer.

  I would like to have the first element of the list selected/focused when I view my list of items.

  If I try to set focus on the first point of

  firstItem.setFocus)

  nothing seems to be happening: the debbugger says "FocusHistory: Focus acquired; App Tesssst; Component TestScreen.

  TestScreen is

  public class TestScreen extends MainScreen{
  
      BitmapField _placeholder;
  
      public TestScreen() {
          super(NO_VERTICAL_SCROLL | NO_VERTICAL_SCROLLBAR);
  
          Background tiledBG = BackgroundFactory.createBitmapBackground(Bitmap.getBitmapResource("grey_tile.png"), Background.POSITION_X_LEFT, Background.POSITION_Y_TOP, Background.REPEAT_BOTH);
  
          getMainManager().setBackground(tiledBG); 
  
          HorizontalFieldManager horizontal = new HorizontalFieldManager(NO_HORIZONTAL_SCROLL|NO_HORIZONTAL_SCROLLBAR);
          CustomVerticalManager listVerticalContainer = new CustomVerticalManager(VERTICAL_SCROLL|NO_VERTICAL_SCROLLBAR);
  
          add(horizontal);
          horizontal.add(listVerticalContainer);      
  
          for(int i=0; i<19; i++){
              _placeholder = new BitmapField(Bitmap.getBitmapResource("imageplaceholder.png"));
  
              HorizontalItemField item = new HorizontalItemField(_placeholder, "ASD", "sukapub", 2, "100$", FOCUSABLE);
              listVerticalContainer.add(item);
              if(i == 0) item.setFocus();
          }
  
          System.out.println("@#@#@# FOCUSED ITEM = "+getFieldWithFocus());
  
      }
  

  This one:

  System.out.println("@#@#@# FOCUSED ITEM = "+getFieldWithFocus());
  

  Returns:

  @# @ #@ # AXÉ ITEM = null

  Firstly, FOCUSABLE is supposed on connectors and downloaders - only fields.  If a manager has any focusable inside fields, its setFocus() will find the first such focus area and set to it. Compare the getFieldWithFocus() and the getLeafFieldWithFocus() to see the difference. In all cases, make sure that your _itemDetails is created focusable.

  Second, I noticed that you do not add _name, _publisher _price to your manager. Your sublayout is not also remove those. I can only imagine you send these fields to be placed somewhere else or

  Thirdly, given that you override sublayout anyway, consider the extension Manager rather than HorizontalFieldManager.  You can also use setMargin _image and _itemDetails drop sublayout() in total.  Even if Field.setMargin was documented in OS 6.0, he works since pretty much forever (my guess is since 4.0.0 - version where XYEdges appeared).

  Fourth - onFocus and onUnfocus managers are odd to say, I wouldn't count on them. onUnfocus, in particular, is wrong even in areas - could not get called at all. Use FocusChangeListener to detect the focus moves. Just add 'implements FocusChangeListener' to your class definition, implement ' public Sub focusChanged (field field, int eventType) and invoke setChangeListener (this) somewhere in the constructor. Respond to the types of FOCUS_LOST and FOCUS_GAINED events inside focusChanged and buttonColor and textColor changes - and don't forget invalidate()!

• List of the HorizontalFieldManager with scrolling focus problem

  Hello

  I'm doing a vertical list of horizontalfieldmanager with an icon and two text fields, but I'm having a problem when scrolling it. I used a nullField to manage focus. When I scroll to the top everything works well, but when I Ahmed to the bottom of the item appears on the edge of the screen.

  I guess that I did not understand how to manage the focusChange metodh and the metodh of the painting.

  All advice will be appreciated.

  Then try to create your NullField with getFocusRect override: like this:

  nullField = new NullField(NullField.FOCUSABLE) {
    public void getFocusRect(XYRect rect) {
      getManager.getExtent(rect);
      rect.setLocation(0, 0);
    }
  };
  

  Paint won't help you - you must tell the system to the entire span developed in order to scroll properly. If the above fails, analyze your focusChanged eventType and make sure that your Manager is fully visible on the screen on FOCUS_GAINED. To do this, you need to use getManager () .getVerticalScroll () / getManager () .setVerticalScroll () as well as of your Manager and getHeight() getTop().

• Strange problem with HorizontalFieldManager - it does not show on real device bitmap

  I have a rather strange problem with the HorizontalFieldManager on my Blackberry 8820, which I did not on the Simulator, or done other blackberries that I tried to install my game.

  The problem is that bitmaps that I add, do not appear on the actual device, as in the images below. The code is provided below as well. No idea how to debug, or resolve is appreciated.

  Here's what I see on Simulator and some devices

  

  Here's what I see on the real blackberry:

  

  Code:

  ......

  OK, I found the solution - the problem is that there seems to be a bug where you can't put more fields button radio on a horizontal layout manager with 4.2.2.x.

  The solution is to extend the RadioButtonField field and replace the positioning method:

  RadioButtonField radioField = new RadioButtonHack ("", textureGroup, isSelected);

  SerializableAttribute public class RadioButtonHack extends RadioButtonField {}

  public RadioButtonHack() {}
  Super();
  }

  public RadioButtonHack (String label, group RadioButtonGroup,
  Boolean selected, long style) {}
  Super (label, group, selected, style);
  }

  public RadioButtonHack (String label, group RadioButtonGroup,
  Boolean selected) {}
  Super (label, selected group);
  }

  public RadioButtonHack (label As String) {}
  Super (label);
  }

  Protected Sub layout (int width, int height) {}
  int temp = this.getPreferredWidth ();
  setExtent (time, height);
  Super.Layout (time, height);
  }

  }

  I had created a HorizontalFieldManager & BitmapFields said that.

  In Blackberry Storm, Display.getWidth () is 480. I want to use 450 first to add some BitmapFields to LHS of the screen I have create running m & add 2 BitmapFields initially to RHS of the screen.

  2 BimapFields that I want to show initially added to the constructor r & othsr BitmapFields that I m create runtime r added afterwords love...

  }
  

  I want startBitmapField & endBitmapField at RHS & bitmapField [i] that I m creating the runtime to LHS of HorizontalFieldManagers.

  I m thinking to add 2 HorizontalFieldManagers. 1 for 1 for startBitmapField & endBitmapField & bitmapField [i]. But how to add 2 HorizontalFieldManagers or any other FieldManagers in a row?

  Any solution? How to do?

• Focus button HorizontalFieldManager on Storm problem

  I have data exploited these forums looking for a solution but found nothing.  The application I've created has a title bar with 3 fields - previous button, label, next button.  Very simple and the layout works very well.  You cannot set the focus to the right button in the simulator of storm.  You can use the keyboard to navigate to it and click back.  But the keys do not work on this button.  If I change the center field to be a button, it works for the Center button.  Never for the right button.  I think it's a bug, but if you know a whole work please let me know.  Here is the code:

           // create previous button, current label, next button        ButtonField prev = new ButtonField("Prev", ButtonField.FOCUSABLE | ButtonField.CONSUME_CLICK);        _label = new LabelField("My Label", Field.FIELD_HCENTER);        ButtonField next = new ButtonField("Next", ButtonField.FOCUSABLE | ButtonField.CONSUME_CLICK);

                  width = getWidth();
                  height = getHeight();

  Solved!

  Basically my manager should not call super, must call layoutChild before positioning and then affecting the scope of the Manager.  Yes, a lot of questions and unfortunately a lot of code examples on this site that.  Please visit this page on the managers how custom must be written:

                  }
              }
          }
      }
  
  }
  

  Then I create: new AddEditField ("address:", cFont, maxSpace);  and add it to a screen.

  When I try to open this form. It is nullpointexception: the eclipse debugger show the info such as:

  AddEditField$ 4labelfield.paint line 385.

  Please help me to check the code. why it can run in 0 s 7.0 and before, only 7.1 has had this problem?

  Thank you

  Hi Flybrid,

  I checked at the time of your code,

  I am able to run your code by deleting page layout override methods in two fields of the label.

  The problem with the substitution of the method of layout in the spaceF and spaceF2 fields.

  But I can't explain why.

  I think that you can achieve the same thing by replacing getPrefferedWidth() and getPrefferedHeight() above the fields instead of page layout.

  Thank you.

• BrowserField encoding problem

  Hello! Please, help me! I spent almost all day, but have had no success. My BrouserField is showing '? ' characters instead of the non-English characters.
  I need to get the Ribbon XML, analyze and display in the BrowserFiled.
  I use these classes:

  (1) WaitScreen - PopupScreen from the example of knowledge base

  public class WaitScreen extends PopupScreen {
  
      private LabelField _ourLabelField = null;
  
      private WaitScreen(String text) {
          super(new HorizontalFieldManager());

          _vfm.add(_ourLabelField);
          this.add(_vfm);
          this.setBackground(BackgroundFactory.createSolidTransparentBackground(Color.BLACK, 225));
      }

  It works very well (showing WaitScreeen, data download), but all characters not English shows as '?'
  I found a few discussions with the same problem (especially this one)

  http://supportforums.BlackBerry.com/T5/Java-development/how-to-show-other-languages-in-BrowserField/...

  and this one

  http://supportforums.BlackBerry.com/T5/Java-development/BrowserField-can-not-display-UTF-8-character...

  but I don't understand, how and where do I I implemented HttpConnection in my code.
  Please, give me advice or tell, how I change my code to solve this problem?

• horizontalfieldmanager limitation

  I just found out that HorizontalFieldManager can not add more than 1 TextField... When I add 2 TextField in a HorizontalFieldManager and then, I transfer the app to my Blackberry, second TextField will not be displayed. Is there such a restriction for some managers?

  This is not a limitation of the Manager, but a problem of the field, it signals a preferredWidth of unlimited and as a hfm has unlimited width (virtually) it grants this wish.

  You can replace getPreferredWidth on the domain or use a custom layout manager.

• Button in the pop-up screen problem

  Hi all

  I did a pop-up screen in which there are two buttons and an EditField. Now, I am faced with very weird problem. First button that I added in my code doesnot seem to work. It doesnot clicking and the second button is working well, why is it so can any body help out me of this.

  I provided the code here: -.

  public class PinPopup extends PopupScreen{
  public static  EditField texts;
  static String _userName=null;
  
  PinPopup()
      {
      super(new HorizontalFieldManager());
      Font f = Font.getDefault().derive(Font.BOLD, 16);
      setFont(f);
      texts=new EditField("","",200,Field.EDITABLE);
  
      ButtonField sendButton = new ButtonField(" Send  "){
          protected boolean navigationClick(int status, int time) {
                 Dialog.inform("Send");
              return true;
              }
      };
  
      ButtonField cancelButton = new ButtonField("Cancel"){

  Hi Please help me in this

  Thanks in advance

  Why do you not use Horizontalfieldmanager for horizontal alignment.

  This is the code and it works fine.

• Problem BrowserField2 demo?

  Hello

  I imported BrowserFieldDemo2 of samples of BlackBerry in my eclipse. If I open any website through BrowserField. I may be able to vertically scroll the webpage, but I'm unable to scroll horizontally.

  I want to see the entire Web page.  What may be the problem?

  The browserfield is a VerticalFieldManager, so it must be the width of what it shows, but it can scroll down.

  Put it inside a HorizontalFieldManager and play a little with the style. For me, it works: Field.FOCUSABLE. Manager.VERTICAL_SCROLL | Field.FIELD_HCENTER | Manager.TOPMOST.
