Add HorizontalFieldManager to ObjectListField

• Puzzled on IllegalArgumentException

  Hello

  I have an app that works well on multiple devices and multiple versions of the OS, but on the simulator of the storm, I get an IllegalArgumentException in the libraries of blackberry as a field is painted.

  The exception occurs when my code for this;

  -building a secondary screen screen called "ListScreen.

  -Adds a specialized ObjectListField class called "ItemListField" with about 10 objects inside a HorizontalFieldManager

  -each object in the list field overload of toString to create a line of text... which part is wider than the screen.

  -the HORIZONTAL_SCROLL and HORIZONTAL_SCROLLBAR style bits are enabled in the HorizontalFieldManager

  Elsewhere in my application this same approach of ListScreen and ItemListField is used in a similar way, with no problems.

  I wrapped around my builders of exception handling, but nothing is taken by my code... just the debugger catches the exception. The exception seems to occur more deeply in the libraries of BlackBerry. I copied the trace at the bottom.

  I use error to isolate the problem, but I have a version which is currently controlled by this problem and it crumbles. Suggestions on the forum to assist in the resolution of the problem or the isolatiing are greatly appreciated.

  You can scale the image with EncodedImage, but it is usually best to use an image with a sufficient size

• How to draw and the positioning of images in FieldManager using the method object?

  Help, please.

  I have already pointed out the problem with USE_ALL_HEIGHT in first Manager add you to the form. Drop this style bit, otherwise sublayout your screen will generate an exception, and nothing appears!

  If you want HorizontalFieldManager to be of a particular size, regardless of the height of managed fields, replace its sublayout:

  HorizontalFieldManager fieldManagerTopBanner = new
           HorizontalFieldManager()
  {
       protected void sublayout(int maxWidth, int maxHeight) {
          super.sublayout(maxWidth, maxHeight);
          int myDesiredHeight = ;
          setExtent(getWidth(), Math.min(myDesiredHeight, maxHeight));
       }
  
       protected void paint(Graphics g)
       {
            // g.setBackgroundColor(0x000000);//blue
               g.drawBitmap(100, 150, 100, 200, jlnLogoImg, 0, 0);
  
            //g.clear();

• Selection field of the day of the week as the appointment screen

  Hello

  I am developing a screen exactly similar to the ' screen new appointment "in the calendar application. But I can't find any appropriate UI component to expand the field of selection of the day of the week.

  In the 'new appointment screen of origin', this field of choice in week appears when you select "weekly" in the choicefield "recidivism". There are 7 characters, one for each day of week & you can select / deselect a day of week by pressing the space bar.

  Now, can someone please give me an idea on how to develop this field?

  Thank you.

  Hello

  Add HorizontalFieldManager and add ButtonFields on measurement (method overload f.e paint.).

  ButtonFieldListener is added to the custom field button.

  If selected the day of the week (given by the manufacturer) paint "BOLD", and another not.

  Kind regards

• v, can add two horizontalFieldmanager in a horizontalfieldmanager

  Hello

  I want labelfield and editfield one under the other.

  and I want to add bitmap border combining two fields... If I want to add two horizontalfield in unique horizontalfield.

  is it possibble?

  «I want labelfield and editfield one under the other.»

  below?  So, you want a vertical zone manager you?

  I imagine that you have two HFM, each with a label and an EditField and you want these below the other.  Add you them to an optimization of resources and then put the following border around a resources optimization.

  Once you start to need to do this sort of thing, you really should look at:

  According to my interpretation of the Javadocs, instead:

  dfm.addCustomField (hfm);

  have you tried that?

• HorizontalFieldManager custom: cannot field presentation, insufficient height or width

  I have two fields to label that I need for available side by side in a manager of horizontal field. When ran, the outputs of the Console: "cannot the field presentation, insufficient height or width.

  When I insert a breakpoint, the values are:

  • width = 480
  • height = 1073741823

  Why is the value of great height? (Oh yes, the virtual height.)

  What is the right way to calculate the height - just use the height field's favorite?

  LabelField lf = new LabelField("Flavor");
  LabelField olf = new LabelField("Order");
  
  HorizontalFieldManager hfm = new HorizontalFieldManager(
          Manager.NO_HORIZONTAL_SCROLL
                  | Manager.NO_HORIZONTAL_SCROLLBAR) {

          int x = 0;
          int y = 0;
  
          for (int i = 0; i < numberOfFields; i++) {
              field = getField(i);

          int myHeight = height;
  
          super.sublayout(myWidth, myHeight);
  
          setExtent(myWidth, myHeight);
      }

          return getScreen().getWidth();
      }
  };
  
  hfm.add(olf);
  hfm.add(lf);
  

  You all that hard work the fields chickens and then try to destroy with super.sublayout () call. I'm sure that's what throws the exception. Check your myWidth and myHeight before the call to super.sublayout (). You might find that getPreferredWidth() returns to zero.

  I don't know why you would want to increase the parameter y in a horizontal field in any event handler. If anything, set x and not just randomly, by 10, but by the field.getWidth (). But it's logical that if you extend the Manager and remove super.sublayout call.

  More important still, you can get what you want much easier to not the substitution of all sublayouts and instead use setMargin on your domains.

• How to add fields on a screen at a particular location where a domain manager is already added

  Hello

  Issue in the user Desiging interface...

  I have a screen where I use two HorizontalFieldManager covering first half and second half of the screen, now my qusetion is that I want to add a field to the second half of the screen but the field is added below the second half of the screen, I know why this is happening because the area of the screen is already filled by the two HorizontalFieldManager.

  So please suggest me how to add the field in the second half of the screen, which sector is already covered by HorizontalFieldManager.

  Here is my sample code...

  Top of HorizontalFieldManager = HorizontalFieldManager(NON_FOCUSABLE | nouveau FIELD_HCENTER |) FIELD_VCENTER);
  upper_part = new BitmapField (upper_bitmap);
  Upper.Add (upper_part);

  Low HorizontalFieldManager = new HorizontalFieldManager(NON_FOCUSABLE |) FIELD_HCENTER | FIELD_VCENTER);
  lower_part = new BitmapField (lower_bitmap);
  Lower.Add (lower_part);

  VerticalFieldManager body = new VerticalFieldManager(NON_FOCUSABLE |) FIELD_HCENTER | FIELD_VCENTER);
  Body.Add (Upper);
  Body.Add (Lower);
  Add (Body);

  Thanks a lot... :)

  Are you using the bitmap for horizontal substantive adding upper and lower field area manager

  If yes don't do that add background to the Manager of horizontal field like this:

  horizontalFieldManager.setBackground (BackgroundFactory.createBitmapBackground (bitmap));

• Problem with the ObjectListField

  Hello

  I have problems with the method getSelectedIndex() ObjectListField.
  Supposedly, when there is no index selected, it returns-1. But how come it always returns the index of the last element?

  To illustrate, I created my own dialog that has similar functionality to the "device window select" Bluetooth BB application. I have an ObjectListField and a Cancel button. What I did simply, is to change the label of the button to show the selected index. I have attached my sample code below.

  public class MyDialog extends dialog
  {
  private ObjectListField m_list;
  private ButtonField m_btn;

  public MyDialog)
  {
  Super ("Select Device:", null, null, 0, Bitmap.getBitmapResource ("bluetoothIcon.PNG"), Manager.FOCUSABLE);

  m_List = new ObjectListField();
  m_btn = new ButtonField ("Cancel", Field.FIELD_HCENTER);
  m_List.set (new String [] {"first", "second"});

  Add (m_List);
  Add (m_btn);
  }

  protected boolean navigationClick (int status, int time)
  {
  m_btn.setLabel (Integer.ToString (m_List.getSelectedIndex ()));

  Returns true;
  }
  }

  Can someone help me on this problem? Is there something wrong with my code, or is the buggy API? All I want to do is to return an index of-1 if there is no selected item in the list.

  Also, I tried the isFocus() method to check if the list is being concentrated, it always returns false even if the list is OBVIOUSLY being focused. I'm running out of options on how to determine the solution to this problem. Help, please!

  Thank you very much.

  @jacylan - I do not use isFocus() to determine if the ListField is net.  Take a look at the following code, I think that with this, you can force-1 when the ListField is not the point.

      protected boolean navigationClick(int status, int time)
      {
          int selectedIndex = m_list.getSelectedIndex();
          boolean listInFocusOption1 = false;
          if ( this.getLeafFieldWithFocus() == m_list ) {
              listInFocusOption1 = true;
          }
          boolean listInFocusOption2 = false;
          if ( m_list.isFocus() ) {
              listInFocusOption2 = true;
          }
          m_btn.setLabel(Integer.toString(selectedIndex) + ":" + listInFocusOption1 + ":" +listInFocusOption2);
  
          return true;
      }
  

• Set the color for emphasis on the interactive whiteboard to HorizontalFieldManager

  I have an array of horizontal fields that contains a bitmap and a labelfield each. The entire line should be clickable who worked until now, but how do I set the color to accent properly? At the moment the onFocus and onUnfocus functions are completely ignored.

  It's the definition of my table:

  for (int i = 0; i < listSize; i++) {
          logInDetailManager[i] = new HorizontalFieldManager(
                  Manager.USE_ALL_WIDTH | Field.FOCUSABLE) {
  
              protected void onFocus(int direction) {
                  super.onFocus(direction);
                  background_color = Color.RED;
                  invalidate();
              }
  
              protected void onUnfocus() {
                  invalidate();
                  background_color = Color.GREEN;
              }
  

  And that's how I add my horizontal fields:

  logInDetailManager[i].setChangeListener(this);
  logInDetailManager[i].add(dummyIcon[i]);
  logInDetailManager[i].add(new LabelField("hello"));
  logInDetailManager[i].add(new NullField(Field.FOCUSABLE));
  add(logInDetailManager[i]);
  

  Thanks for your help!

  AAH it got already...

  If someone has trouble with this too: I removed onFocus() and onUnfocus and set the background color in the paint so the color of the entire line method is modified when:

  protected void paint(Graphics graphics) {
  
      graphics.setBackgroundColor(isFocus() ? Color.RED : Color.GREEN);
      graphics.clear();
      invalidate();
      super.paint(graphics);
  }
  

• 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.

  HorizontalFieldManager horsnMgr = new HorizontalFieldManager(Manager.FIELD_HCENTER){

     layoutChild(fieldSortName, fieldSortName.getPreferredWidth(), fieldSortName.getHeight());
     setPositionChild(fieldSortName, 0, 0);
     layoutChild(buttonBrowse1, fieldSortName.getWidth(), buttonBrowse1.getHeight());
     setPositionChild(buttonBrowse1, Display.getWidth()/2, 0);
     layoutChild(fieldCustNo, fieldCustNo.getWidth(), fieldCustNo.getPreferredHeight());
     setPositionChild(fieldCustNo, maxWidth - fieldCustNo.getWidth(), 0);
     setExtent(maxWidth, fieldCustNo.getHeight());
   }};
  horsnMgr.add(fieldSortName);
  horsnMgr.add(buttonBrowse1);
  horsnMgr.add(fieldCustNo);
  vMgr_Main.add(horsnMgr);
  

  Any help will be very appreciated!

  screen_width = Display.getWidth();
  field_width = screen_width/3+1;
  
  fieldSortName = new EditField("SortName:", "", 10, Field.FOCUSABLE);
  fieldCustNo = new EditField("CustNo:", "", 5, Field.FOCUSABLE);
  buttonBrowse1 = new ButtonField("..", Field.FOCUSABLE);
  
  TableLayoutManager tlm = new TableLayoutManager(new int[]
  {
      TableLayoutManager.FIXED_WIDTH,
      TableLayoutManager.FIXED_WIDTH,
      TableLayoutManager.FIXED_WIDTH,
  }, new int[]{
           field_width,
           field_width,
           field_width,
  }, 0, Manager.VERTICAL_SCROLL | Manager.VERTICAL_SCROLLBAR | FIELD_HCENTER | FIELD_VCENTER);
  
  tlm.add(fieldSortName);
  tlm.add(buttonBrowse1);
  tlm.add(fieldCustNo);
  add(tlm);
  

  Did the same thing yesterday, but with three buttons...  I used the TableLayoutManager.
