• Slider custom text field (Cap) does not appear

  All;

  I created a custom text field based on the standard text field, changes work fine (really just a custom height and width and a border).  The problem is the method of painting which seems to remove the cap of the field when it gets the focus.  To be clear the carret never shown at all.

  public class CustomText extends TextField //cutom text field width
  {
      //Custom Height and Width in Pixels
      final static int textwidth=125;
      final static int textheight=25;
  
       CustomText()
       {
       super(); // Call the default constructor    
  
       //Border for text fields
       XYEdges padding = new XYEdges(5, 5, 5, 5); //space between box and border
       Border theborder = BorderFactory.createSimpleBorder(padding, Border.STYLE_SOLID);
  
       //Assign the border to the object
       this.setBorder(theborder);
       }
  
       public void onFocus( int direction )
       {
          super.onFocus( direction ); //invoke parent procedure
          invalidate(); //mark for redraw
       }
  
       public void onUnfocus()
       {
      super.onUnfocus(); //invoke parent procedure
      invalidate(); //mark for redraw
       }
  
       //Override the layout with the custom Width and Height
       protected void layout(int width, int height)
       {
          super.layout(textwidth,textheight);
          setExtent(textwidth,textheight);
  
       }      
  
      //Override the display message such that no message is displayed when the field is full
      protected void displayFieldFullMessage()
      {
      }
  
      //Override the default paint method to call the super class constructor and then assign the border
      protected void paint(Graphics graphics)
      {
         // int prevColor = graphics.getColor(); //Save Previous Color
          graphics.setBackgroundColor(Color.LIGHTGRAY); // Set to Gray
          graphics.clear(); // Clear for redraw
          super.paint(graphics); //Force Redraw of Object
        //  graphics.setColor(prevColor); //restore for cursor paint
  
      }
  
  };
  

  In the paint in the first and last method lines that are commented out were a soloution that I tried after reading on this subject.  Something along the lines of the restoration of the default color, but unfortunately without success.   Any ideas would be more useful

  Thank you!

  Quick thoughts:

  (a) to remove the requirement to substitute paint by setting the background a Color.LIGHTGRAY using the base class

  (b) you put on the field by using this:

  Super.Layout (TextWidth, TextHeight);

  If you then do the following:

  setExtent (textwidth, textheight);

  you are likely to confuse the field.  If you still want to use the entire height and use the full width and then try to deal with it in the Style, that is, replace this:

  Super(); Call the default constructor

  with this

  Super(TextField.USE_ALL_HEIGHT |) TextField.USE_ALL_WIDTH); Call the default constructor

  (c) why you override onFocus and onUnfocus?  I would like to delete these if you do not have anything specific to these methods.

  Make these changes, and you'll have a more simple TextField.  See if these changes will solve the problem of the caret too.

• FieldFullMessage custom

  Hi, I want to show a custom instead of the message message "full field". I followed: solution .

  I can view the message, but the State is not removing, after 2 seconds. What is the solution for this?

  The substitution of displayFieldFullMessage() caused another problem as well.

  On all devices, if the user copy & paste a new text, the message could not be deleted.

  I have sloved the problem by creating another thread and invoking status.show as shown below:

  protected void displayFieldFullMessage() {
      new Thread(){
        public void run(){
              UiApplication.getUiApplication().invokeLater(new Runnable() {
                public void run() {
                  String message = FIELD_FULL_MSG;
                  Status.show(message,1000);
          }});
          }
  }.start();
  

  This code solved my problem on all devices, including the storm.

• BasicEditField customization

  I extend a bisiceditfield in the following way...

          class MonthField extends BasicEditField{ 
  
              MonthField(){
                  super(null,"JAN", 3,FILTER_DEFAULT);
              }
  
              public int getPreferredWidth() {
                  return this.getFont().getAdvance("JAN"+" ");
              }
              protected void layout(int width, int height)  {
                  super.layout(getPreferredWidth(), height);
              }     
  
              protected void displayFieldFullMessage(){                
  
              }
        }
