• Change the color of the text of the CheckboxField?

  Hi all

• Extending from CheckboxField

  I have this image selector I use because I'm stuck with 4.6.1 and FilePicker does not make an appearance until 5.0.0. So I extended the CheckboxField class and written methods of painting and the layout with this code

  protected void paint (Graphics pGraphics)

  {

  pGraphics.setColor (0x0000FF00);

  pGraphics.drawBitmap (0, 0, 75, 75, vImage, 0, 0);

  If (getChecked ())

  {

  pGraphics.fillRect (0, 0, 75, 10);

  pGraphics.fillRect (0, 0, 10, 75);

  pGraphics.fillRect (75, 65, 0, 10);

  pGraphics.fillRect (0, 65, 75, 10);

  }

  pGraphics.setColor (0x00000000);

  pGraphics.drawText (getLabel (), 80, 30);

  Layout (GetWidth (), 75);

  setExtent (getWidth (), 75);

  }

  protected Sub layout (width int, int height)

  {

  Super.Layout (width, 75);

   super.setExtent (width, 75);

  }

  

  Seems to work by program very well, but as you can see on the screenshot the focus highlighter (not the isSelected highlighter, just to be clear) is well off his mark, I want to be around the full text of the label or the entire image and the text.

  Anyone have any ideas on how to achieve this.

  Nevermind

  public Sub getFocusRect(XYRect pRect)

  {

  super.getFocusRect (pRect);

  pRect.set (0, 0, (int) vTargetWidth + getFont () .getAdvance (getLabel ()) + 5, (int) vTargetHeight);

  }

  could someone help me with this?

  This is the first time make app with GUI

  Gentlemen.

  slow down, please!

  Absolutely, totally useless any Manager available personalized for that! In order to organize two or more fields in a 'line', you just all of them to the same HorizontalFieldManager! The manager then places them from left to right in the order that you add them.

  That said - you have a slight problem in your EditField. EditField is "width-hungry" - it consumes the entire width, it is given, do not leave anything for the rest fields. To combat that, to deceive him into thinking he's got less space. We will give him what he needs to label 6 larger figures (s '8' or '9's, not '1') and a space for the padding. We will then have something like:

  _Id = new EditField("Id : ", "", 6, EditField.FILTER_NUMERIC) {
    protected void layout(int width, int height) {
      Font myFont = getFont();
      int myWidth = myFont.getAdvance(getLabel()) + myFont.getAdvance("8") * 6 + myFont.getAdvance(" ");
      super.layout(Math.min(myWidth, width), height);
    }
  };
  _check = new CheckboxField("check", false);
  HorizontalFieldManager hfm = new HorizontalFieldManager();
  hfm.add(_Id);
  hfm.add(_check);
  add(hfm);
  

  Enjoy!

• CheckboxField, on the same line with OS6

  Hello

  I'm testing my apps for compatibility with OS6.  I discovered that if I have more controls, and then another on the same line, behavior went from OS5.  The first control's display while the other controls are moved outside of the screen.  Any idea on how to solve this problem while keeping compatibility?  Here's the code I'm referring to:

  HorizontalFieldManager hfmOperator = new HorizontalFieldManager(HorizontalFieldManager.USE_ALL_WIDTH);
  
  int intRightSpace = Display.getWidth()/10;
  
  LabelField lblOperator = new LabelField("");
  lblOperator.setFont(Font.getDefault().derive(Font.PLAIN, 18));
  lblOperator.setPadding(0, intRightSpace, 0, 0);
  hfmOperator.add(lblOperator);
  
  chkADD = new CheckboxField("+",  Param.boolActiveADD);
  chkADD.setFont(Font.getDefault().derive(Font.PLAIN, 24));
  chkADD.setPadding(0, intRightSpace, 0, 0);
  hfmOperator.add(chkADD);
  
  chkSUB = new CheckboxField("-",  Param.boolActiveSUB);
  chkSUB.setFont(Font.getDefault().derive(Font.PLAIN, 24));
  chkSUB.setPadding(0, intRightSpace, 0, 0);
  hfmOperator.add(chkSUB);
  
  chkMUL = new CheckboxField("*",  Param.boolActiveMUL);
  chkMUL.setFont(Font.getDefault().derive(Font.PLAIN, 24));
  chkMUL.setPadding(0, intRightSpace, 0, 0);
  hfmOperator.add(chkMUL);
  
  chkDIV = new CheckboxField("/",  Param.boolActiveDIV);
  chkDIV.setFont(Font.getDefault().derive(Font.PLAIN, 24));
  chkDIV.setPadding(0, intRightSpace, 0, 0);
  hfmOperator.add(chkDIV);
  
  add(hfmOperator);
  

  The only way I could get to this day is to override the method of layout in the CheckboxField and spend a fixed width to the super method:

  protected void layout(int width, int height) {
      super.layout(100, height);
  }
  

  The problem with this approach is that the width of the content can vary from a device to according to the size of font by default, etc. and it may be possible to try to force a specific width.

• CheckBoxField question

  Hello!

  I want to add checkboxes in a dynamic way to the Senior Manager.

  while (reItems.hasNextElement())
              {
  ck1 = new CheckboxField(string, boolean);
  add(ck1);
  }
  

  Later, I want to get the value of each of them. How can I do?

  Go to table of checkbox fields.

  CheckboxField checkbox[];
  checkbox=new CheckboxField[size of your reItems];
  
  while(reItems.hasNextElement)
  {
       checkbox[value]=new CheckboxField("Name", false);
       add(checkbox[value]);
  }
  

  Then you can get the values of each.

• CheckboxField [] and fieldChangeListener.

  Hello

  I need a dynamic number of checkboxes for a project I'm working on. My code example is as follows. Somehow, I get an jvm stackoverflow exception.

  public class abc() extends screen implements {FieldChangeListener}

  CheckboxField [] boxField;

  public abc() {}

  .

  .

  .

  the length is variable.

  boxField = new CheckboxField [length];

  VFM VerticalFieldManager = new VerticalFieldManager();

  for (int i = 0; i)

  boxField [i] = new CheckboxField();

  boxField [i] .setChangeListener (this);

  VFM. Add (boxField [i]);

  }

  Add (VFM);

  }

  Sub fieldChanged (field field, int context) {}

  Hardcode for now. The intention is to loop through and uncheck all

  except one who was just ticked.

  chkBoxField [0] .setChecked (false); StackOverflow exception

  }

  }

  Help?

  In this way:

  chkBoxField [0] .setChecked (false);

  You set the value of the checkbox, prompting to advise its FieldChangeListener, which is to set the value of the box, which advises the FieldChangeListener... I could go on.   Until what I stack overflowed of course.

  Although there are many ways to stop this, I think that you should be aware of using the context provided to the fieldChanged method.  To check

  FieldChangeListener.PROGRAMMATIC

  If it matches, then the change was made by a program and not by the user, in which case you should ignore the change.

  For example:

  Sub fieldChanged (field field, int context) {}

  If (context == FieldChangeListener.PROGRAMMATIC) {}

  Only to process user changes to checkboxes

  return;

  }

  .....

  Hope it makes sense.

  Edit: this has been creating during the validation of RexDoug, my apologies for the repetition.

• When you close the popup only proceed

  Hello

  In my fieldChanged(), I ask a pop-up message. The popup has a close button that closes the popup. I don't want the application to perform the work until the context menu does not close. I am not able to do this. The code is:

      public void fieldChanged(Field f, int context) {
          System.out.println("Into ------------ BUTTON CLICKED = " + f + " C0NTEXT = " + context + " btnClicked = " + btnClicked);
          if (f instanceof CheckboxField) {
              CheckboxField cb = (CheckboxField) f;
              // Get details associated with the selected checkbox
              UiApplication.getUiApplication().invokeAndWait(new Runnable() {
                      public void run() {
                          getScreen().getUiEngine().pushScreen(new MessagePopup(mm1));
                          return;
                      }
                  });
                  // Change some data and invalidate
                  if (mm.read == false) {
                      mm.read = true;
                      cb.setCookie(mm);
                      unreadCount -= 1;
                      if (unreadCount < 0)
                          unreadCount = 0;
                      System.out.println("UNREADCOUNT =  " + unreadCount + " ******************* ");
                      inboxBtn.setText("Inbox " + unreadCount);
                      invalidate();
                  }
                  System.out.println("CheckBox Complete");
               }
          }

          private BitmapButtonField okBtn;
  
          public MessagePopup(MailMessage mm) {
              super(new VerticalFieldManager(VERTICAL_SCROLL | VERTICAL_SCROLLBAR));
              okBtn = new BitmapButtonField(Bitmap.getBitmapResource("res/cancel_btn.png"));
              okBtn.setChangeListener(this);
              add(new LabelField("Label "));
              add(okBtn);
          }
  
          public void fieldChanged(Field field, int context) {
              if (field == okBtn)
                  this.close();
          } 
  
          protected boolean keyChar(char key, int status, int time) {
              if (Keypad.KEY_ESCAPE == key) {
                  this.close();
                  return true;
              } else
                  return super.keyChar(key, status, time);
          }
      }
  

  The output is: popup appears and I see the following SOP

  CheckboxField Selected * READ = false *.
  UNREADCOUNT = 4 *.

  Complete box

  According to me, when I click on the Ok button in the pop-up window and then 2 lines that is below

  UNREADCOUNT = 4 *.

  Complete box

  must be executed.

  No idea how to work with this scenario. Any help is very appreciated.

  Thank you

  As I understand it, you don't want "if(mm.read == false)" to get executed until the screen closes?

  If this is correct then replace "pushScreen' by 'pushModalScreen '. Block screens mode until the screen is closed. You have not need surgery of invokeAndWait from the modal screen will block the execution anyway.

• 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:
