• Problem with maintaining the original text of basiceditfield even on unfocus after typing the text.

  I have a Basiceditfield with the original text. Here is the code:

  {
  protected void onFocus (int direction)

• Why the setFocus() and setText() methods does not work for BasicEditField

  Hello

  I tried to apply the methods of setFocus() and setText() on a BasicEditField, but he always up "illegal state exception.   However, the getText() method can work.

  Another thing would be - if you use filters on your EditField and allows you to define something that is not allowed by the filter, it will throw an exception setText()...

• Delimit by BasicEditField with media

  I have a BasicEditField that contains the area code of a telephone number and want the text in square brackets. So that the user sees "enter the area code: (_) ' where they can enter their area code in this space.

  I know a way to do so would make a horizontal on the back field Manager ")", but thought that someone would know a better way to do it. Any thoughts?

  I finally understand - thought I'd share in case - that someone has had the same question: (do not forget that you add to the field, so when you use the data you lop this additional support.)

  areaCode1Field = new BasicEditField("Area Code: (", "", 20, Field.EDITABLE)
                  {
                      //Add on the other bracket
                      public void onUnfocus()
                      {
                          if (this.getTextLength() ==3)

• Capture the Keycodes / keyDown in BasicEditField with digital filter

  I tried to understand cela other posts and the API, but I can't seem to get it.

  I created a BasicEditField and applied a filter TextFilter so that it can accept only digital entries. It is the substitution of the event keyDown as expected, but I can not just to capture "1,2,3,4,5,6,7,8,9,0" - he used ' enter my conditional statements - which of course means that the controls do not work.

  I tried the keycodes of compairing the raw numbers, converted characters, KEY_NUM2 and basically everything that was suggested, but I'm obviously missing something.

     BasicEditField numEnter = new BasicEditField()    {     protected boolean keyDown(int keycode, int time)      {             int key = Keypad.key(keycode);                //char key = (char) Keypad.key(keycode);              //this.setText(Integer.toString(key));
  
            //if (key == Characters.DIGIT_ONE)            //if (keycode == 570163217)               if (key == 01)                {                                 this.setText("ONE");              }             else if (keycode == 45219842)             {                                 this.setText("TWO");              }
  
            return false;     } };
  
    // set the filter numEnter.setFilter(TextFilter.get(TextFilter.NUMERIC));
  
   // add to field manager   hfm_logo.add(numEnter);
  

  As always, your help is always appreciated.

  Well...

  It is the solution that I came. Don't know if it's fair, but it seems to work.

  Basically, with the NumericFilter codes keyboard is the same as if you have the filter applied or not to the text box, so even if you override the keydown it doesn't matter if you're trying to intercept him because he gives you the key you pressed on, not what appear after the filter.

  That being said, if you try to do this in the keyDown as you cannot capture because the character needs to be painted on the screen first, otherwise you get an error happens nowhere. So if you paint the screen first and then take some text is located in the numEnter, then put it to white even once, you can capture the NUMBERS that are entered (forcably) on each keyboard phone.

  9000

  8110

• How to USE the information the user entered via BasicEditField or AutoTextEditField

  What BlackBerry watch document - step by step - how to extract the data that the user has typed on the screen using BasicEditField or AutoTextEditField. and use it in a Java program? If BB doesn't have a good document, here are all the samples you have found useful?

  I'm sorry, I didn't know that you had already gone through everything that is available.  And Yes, I was aware that the tutorials do not directly provide your requirement.

  How do your right justify a BasicEditField in a screen?

  If you do the following, framed in any case left field shows:

  Processes = new BasicEditField ("process", 7, Field.FIELD_RIGHT);
  This.Add (processes);

  If you create a LabelField, you can right-aligned it on the screen with this:

• Store a copy in a BasicEditField

  Try to keep a double in a BasicEditField or similar (RichTextField, Etc) but I don't have the option for 'setValue', only setText.

  When I try to setText():

  It gives the error ' the setText (String) of the method in the BasicEditField type is not applicable for the arguments (Double). "

  Ideas?

  paymentField.setText(new Double(payment));
  

  Convert double to a string.

• BasicEditFields will not be displayed in HorizontalFieldManager

  I have 3 BasicEditFields next to each other, but when I place it in a HorizontalFIeldManager, one appears where it should be on the left, but the other two do not.

  Any ideas on how I can fix this? Thank you.

  Scott

  QCB is correct, that basiceditfields do not play fair, because they will be the default use full width, which doesn't leave much space for the remaining fields.

  You have two choices:

  (a) BasicEditField override to limit the used width - you can do this by substituting the layout and getPreferredWidth.  There are a lot of similar questions on the forum, I'm sure if you search you can find another person who posted code that does.

  (b) change you Layout Manager so that it restricts the width that it helps the BasicEditField.  The TableLayoutManager sample provided by RIM (see the knowledge base) shows an example of this.

  Which of these two approaches you choose will depend on the conditions of Application.

  Note that you must take into account what happens on a storm in Portrait modes and landscape.

• BasicEditField: set the Focus

  Hello

  If I do not substitute the field basicEdit layout() method, it takes the entire screen width.

  The following code creates an EditField, but I can't focus on that, everything I type I am not either.

  I tried to overridding method object. It still does not.

  Please guide me.

  Background = BackgroundFactory.createSolidBackground (Color.WHITE);
          
  statusMsgFieldEdit = new BasicEditField ("", statusMsg, 140, FOCUSABLE) {}
  Protected Sub layout (int width, int height) {}
  width = 200;
  height = 40;
  setExtent (width, height);
  }

  public int getPreferredHeight() {}
  Return to 40;
  }

  public int getPreferredWidth() {}
  Return Display.getWidth ();
  }
  };
  statusMsgFieldEdit.setBackground (background);

  The other thing is that you must tell the EditField what are its limits, so that it can adjust its alignment won.  So instead of:

  Protected Sub layout (int width, int height) {}
  width = 200;
  height = 40;
  setExtent (width, height);
  }

  You should really do

  Protected Sub layout (int width, int height) {}
  width = 200;
  height = 40;
  Super.Layout (width, height);
  }

• Focus BasicEditField and buttons problem

  Objective:

  -------------------------------------

  To develop Blackberry app without sequence of focus problem when using the BB with trackpad

  The problem:

  --------------------------------------

  I have 5 BasicEditFields and 5 buttons. All objects are aligned vertically. When I move the finger on the trackpad, update doesn't move from one BasicEditField to another, some are fried, and this happens also with buttons, for example, when the focus is on the first button in the row, and then for some reason when I move the finger on the trackpad button next emphasis is not the one below , but attention "jumps" to the last button. Is possible to set 'order of sequence focus' or something like that?

  If you have Blacberry with touchscreen is not a problem, but if develop you some app for example BB Curve 9360 which has only trackpad, so you cannot select all items.

  Software used:

  ------------------------------------

  Eclipse SDK Indigo version 3.7.2.

  BlackBerry Java plug-in 1.5.0.201112201607

  Operating system:

  -------------------------------------

  Win7 64 bit

  Well, I have the solution

  Don't know why it works, but it does.

  I did two things:

  1.)

  I replaced .add with insert and then add Index numbers

  2.)

  This added to the code:

  protected boolean navigationMovement (int dx, int dy, int, int time status) {}
  Returns false;
  }

  I tried without step 2). but then focus jump bad, in any case, it now works as it should.

  Thank you all for your time and your suggestions.

• Calculation of the minimum required size for a BasicEditField

  Hello

  I hope someone can help! This is continued in another post, I had about resize a BasicEditField so I could put a button on the same line.

  I re-size my BasicEditField to be half the width of the screen. I also set the maximum number of characters which they reached 6. When the user tries to enter the character 7 I get an alert that the field is full. I have a border around the BasicEditField and the user, it seems they should be able to enter more characters that is to say the space to enter the number is much larger than 6 characters.

  Does anyone know a way to calculate the size so the domain will be the right size it of to say to fit to the label and up to 6 characters, but not bigger?

  I hope I've explained this well enough to understand. Thanks in advance for any help

• Matter of style BasicEditField

  Hi all

  IM using BasicEditField that I need to enter the characters in all CAPITALS, so I used the "BasicEditField.FILTER_UPPERCASE" style, when I did I was able to enter the uppercase characters, but I'm not able to enter the SPACE.  I travel in Virtual_KEY_BOARD in the space key is disabled.

  Same BasicEditField.FILTER_UPPERCASE | "BasicEditField.FILTER_DEFAULT" is also down. So how to get there, one guide me.

  Thanks in advance

  Anil

  This give a try.

  UppercaseTextFilter uptf = new UppercaseTextFilter() {}
  public char convert (character char, int status) {}
  If (character == Characters.SPACE) {}
  Returns the character;
  }
  Return super.convert (character, status);
  }
  public boolean validate (char character) {}
  If (character == Characters.SPACE) {}
  Returns true;
  }
  Return super.validate (character);
  }
  };
  BasicEditField bef = new BasicEditField ("upper Test:", null);

  I think bef attributes appropriate for you.
