• Unable to choose 'clear history' - it is greyed out and unselectable

  I can't select 'clear history' - it is greyed out and unselectable on my laptop. Only, it happens on my laptop, but shows my story for many months in the past and includes the history both of my desktops, which is supposed to be cleared frequently. Sync is enabled on all devices, and history does not appear on desktop computers. I am able to clear the history on desktop browsers, but not the laptop.

• Lost the power meter of my office - and it is therefore more 'selectable' inside the 'Settings' box of Notifications. Its information line shows currently in gray (unselectable) text instead of the text in black (of your choice).

  I lost the power meter of my office - this little icon that shows when your laptop is plugged in the current House, and where your battery level is when you're not connected to the power of the House

  The problem I found is that it does not appear in mode 'selection' in the 'Settings' box of Notifications.
  Its information line currently shows the text in gray (unselectable) color rather than black (selectable).

  For unknown reasons, the tutorial of vistax64 does not help, so I don't see why not, there is another way...

  Do a system restore. Choose the date where all the icons in the taskbar were present and functional as your restore point.

  Start button > Search box, type system restore > press the Enter key > uac prompt > click on choose a different restore point > next > select dates as your restore point, until the click > next > finish
  To sit and wait. The machine restarts when it's done.

• Right-aligned a RichTextField?

  I can't seem to get an RTF to right-aligned.

   int[] offsets = { 0, 12, subHeadStr1.length() };
   byte[] attributes = { 0, 1 };
   RichTextField line1 = new RichTextField(subHeadStr1, offsets, attributes, fonts, RichTextField.NON_FOCUSABLE | RichTextField.FIELD_RIGHT);
  
   LabelField line2 = new LabelField(subHeadStr2, Field.NON_FOCUSABLE | Field.FIELD_RIGHT);
   line2.setFont(fonts[0]);
  
   VerticalFieldManager vfmSubHead = new VerticalFieldManager(VerticalFieldManager.USE_ALL_WIDTH | Field.NON_FOCUSABLE);
   vfmSubHead.add(line1);
   vfmSubHead.add(line2);
  

  The 'line 2' LabelField gets justified right very well, but not the RTF.

  Any suggestions?

  Please note that I have not tested myself so maybe it's just a herring-saur, but looking at the documentation for RichTextField there are a number of constant static defined, which is TEXT_ALIGN_RIGHT. Hopefully this by using instead of FIELD_RIGHT?

  Also, sometimes you can use the DrawStyle constants. So if TEXT_ALIGN_RIGHT does not work, try DrawStyle.RIGHT

  Let me know how it goes.

• Editable RichTextField does not allow edit

  If a RichTextField can be changed?  I can't get this to work.  Here is a code:

  _rtf = new RichTextField(RichTextField.EDITABLE);
  
  _rtf.SetText("Something I will change);
  

  However, when I run the present on the device, I can focus on the field, but cannot change it (typing does nothing).  Any ideas?  If a richtextfield can be changed (I guess that one b/c it has this property)?  Is there another type, I should use?

  Thank you

  Scott

  RichTextField is read-only. An EditField should fit if you want to change.

  K so I finally solved easily using the following property in each object - RichTextField

  RichTextField.TEXT_ALIGN_HCENTER

  And that solved everything.

• Storm Long RichTextField

  Hello comrades!

  I had a situation associated with RichTextField that contains a long text on the device of the storm.

  The problem is: I am able to scroll the text, but I can't move the focus to a CustomBitmapField, are complemented by the text Manager, until I reach the end of the text.

  The button appears on the screen, but when the user clicks the text above simply scroll down.

  Everyday learning!

  A big thank you Vignesh J. for the idea.

  So, I just replace the touchEvent at the level of the screen, but rather to return false when the target button was not clicked on return "super.touchEvent (event)". And then it works! Not sure if this solution is the best.

  In addition, as suggested, we composed a ClickListener instead of implements FieldChangeListener.

  public interface ClickListener {
     public boolean onNavigationBallClicked(Field f,int status, int time);
  }
  
  public class IntroScreen extends FullScreen implements ClickListener {
  
  ...
  
    startQuiz = new CustomBitmapField(startQuizFocused, startQuizNormal,
                  FIELD_HCENTER | FIELD_VCENTER);
    startQuiz.setClickListener(this);
  
  ...
  
  protected boolean touchEvent(TouchEvent event){
      int x = event.getX(1);
      int y = event.getY(1);
      int index = getFieldAtLocation(x, y);
      try {
          Field f = getField(index);
          if (f instanceof CustomBitmapField) {
              switch(event.getEvent()){
              case TouchEvent.DOWN:
                  f.setFocus();
                  invalidate();
                  return true;
              case TouchEvent.UNCLICK:
                  return ((CustomBitmapField)f).getClickListener().onNavigationBallClicked(this, 0, 0);
              }
          }
      } catch (Exception e) {
          return super.touchEvent(event);
      }

• How to get RichTextField to wrap

  Good afternoon fellow developers:

  I was wondering if someone can help me with my problem. I try to get the text to my RichTextField to wrap when I place it in a verticalManager. Basically, if I have:

  Super (NO_VERTICAL_SCROLL);

  lblUserText

  = new RichTextField ("Please select one of the following options below :"); ")

  VerticalFieldManager = vor

  new VerticalFieldManager()

  VFM. Add (lblUserText)

  Add (VFM);

  The text in the RichTextField wraps to the next line very well. But if I do the following:

  Super

  (NO_VERTICAL_SCROLL);

  lblUserText

  = new RichTextField ("Please select one of the following options below :"); ")

  VerticalFieldManager = vor

  New

  VerticalFieldManager()

  {

  protected void paint (Graphics graphics)

  {

  graphics.setBackgroundColor (0xE8E691);

  Graphics.Clear;

  graphics.setColor (0x000000);

  graphics.drawText (lblUserText.getText (), 0,0);

  }

  };

  The text didn't get dressed. It turns off the cut horizontally the "below:" text. Even if I say:

  Super (NO_VERTICAL_SCROLL |) NO_HORIZONTAL_SCROLL);

  It does not work. What I am doing wrong?

  Nothing.

  If you want to support the RichTextField painting yourself, you must implement the package yourself.  drawText painted a line (and a single line).  So you find where the break lines, paint the text on a single line, down the 'y' and paint the next line by the following (and so on).

• RichTextField truncation of text or ellipsis

  Hi I'm new to dev Java of BB and I'm trying to truncate the text to a non-focusable RichTextField. Is this possible?

  I tried without success to the following:

  ...RichTextField _myRTF = new RichTextField(my_text, off, attrs, fonts, (DrawStyle.ELLIPSIS |
    RichTextField.FIELD_LEFT |
    RichTextField.NON_FOCUSABLE |
    RichTextField.NO_NEWLINE)) { ... };...
  

  I also tried to use Labelfield.ELLIPSIS with no luck. This works for LabelField, but I use RichTextField because I'm using different font styles.

  I ended up using LabelField with LabelField.ELLIPSIS, overiding the paint method and setting the police in there.

• RichTextField setText lower other components?

  I searched this forum a bit.  If I found the correct messages, it seems that I need to use a vertical Manager, but most of the posts I found related to vertical managers were to add scrolling.  It's different.

  I have a screen that has the following in the following order:

  LabelField

  SeparatorField

  RichTextField

  SeparatorField

  ButtonField

  When you click ButtonField, a large amount of data is sent to the RichTextField.setText method.  Instead of SeparatorField and ButtonField which are below the RichTextField moving downwards so that the data can be displayed correctly, it displays all the data but it moving my components above off the screen (at the top).

  Is a manager of vertical, do I have to use to make the SeparatorField and the ButtonField which are below the RichTextField down?

  Look at getVerticalScroll and setVerticalScroll Manager.

  Select the field before doing this.

  Note that in my experience it will not be respected if the field in short could be hidden.

• Problem with RichTextField on the storm

  In two of my apps, I have a screen that is nothing more than display, image and a RichTextField. I have received a complaint that scrolling cannot be done on the RichTextField, that contains several lines of information. However, in the Simulator, it seems that with a right click and drag, scrolling can be accomplished.

  The user uses os 4.7.0.148.

  Can anyone provide some ideas?

  Kind regards

  Scott

  The application is compiled under JDE 4.7?

  If no, the scrolling is problematic in compatibility mode - this is actually backwards and extremely counterintuitive.

• RichTextField focusable

  How to make a RichTextField focusable, but that can be selected or not editable?

  What I want is a field that has the text formatting of a RichTextField options but behaves like a LabelField set to Focusable.

  I want it all to be highlighted when it gets the focus.

• Add ellipses to a multiline RichTextField

  Hi, this is the code of my custom text field Multiline Rich

  As you can see it is very easy to display several lines.

  The problem is that I want to add more features

  Firstly, as a parameter I sent you of the lines, the witch is the maximum amount of the lines I want.

  If the text is too short, I want that number to decrease. Now the text field happens to a lot of height.

  Secondly, the text is too long to be requested amounting to line, at the end of the text, there must be an ellipsis.

  Any ideas?

  public class CustomMultiLineTextField extends RichTextField {
  
      private int lines;
