• Problem with EditField?

  Hello

  I created an EditField and iam trying to make a rectangular shape of it, but the problem is while typing cursor comes from new line and it increases the width of the textfield.  Please find the picture below.  I expect that letters should be on the left is not down. For example, in the browser of the Simulator, there are a TextBox it behave like that.  I added the rectangle to textfiled I think it takes the screen.  Please provide a useful for the same code snippet.  Thanks advanced

  edit = new EditField("", "",50, EditField.FILTER_DEFAULT | EditField.NO_NEWLINE)
          {
              protected void layout(int maxWidth, int maxHeight) {
                  super.layout(137, this.getHeight());
                  setExtent(137, this.getHeight());
              }
              public void paint( Graphics graphics ) {
                  graphics.setColor(Color.RED);
                  System.out.println("!!!!!!!!!!!!!!!!!Width :: "+getWidth());

• Bimap field + EditField click problem

  Hello

  In my application, I am increasing and decreasing value in an editfield using two buttonfields, everything works fine, but if I click on the changed value in the editifeld picture but menu "Application report" come again by pressing ESC and then only I am able to click on the image.

  Even if I click editfield also 'switch' application menu pop up appears please check the picture of the call and inform me how to limit this menu in the click bimap and editfield

  Note: earlier in the popup 'application Switch, close' options appear in the context menu, but after using the below only switch application code comes

  protected void makeMenu (menu Menu, for example int)
  {
  menu.deleteAll ();
  }

  If you return false, you indicate that you have not consumed the event (and a few other layer will be, so the menu).
  return true instead.

  Here is the code how I did it...

  but I know where I am doing wrong...

  but I don't get how to solve this...

  edit.setChangeListener (new FieldChangeListener() {}

  ' Public Sub fieldChanged (field field, int context) {}

  int length = edit.getTextLength ();
  If (length! = 0) {}
  String [];

  If (length % 2 == 0) {}
  int size;
  If (length / 2 == 0) {}
  size = 1;
  } else
  size = length / 2;
  String = new String [size];
  int j = charIndex;
  StringBuffer buffer = new StringBuffer();
  for (int i = 0; i)< size;="" i++)="">

• EditField: protected boolean insert (...) not called if the device uses VirtualKeyboard

  Hi all

  I extend the EditField class to intercept the entries of tank / backspaces and do something. I would outweigh all the methods of the superclass:

  protected boolean insert(char arg0, int arg1);
  public int insert(String text);
  protected int insert(String text, int context);
  
  protected boolean backspace();
  protected int backspace(int count, int context);
  public int backspace(int count);
  

  I tried on a 8520 (which has a physical keyboard) and the methods overridden were correctly when you type something in the field. However, this is not the case on a touch device (tried on a 9380). In this case the text is typed and showed correctly in the EditField custom, but not the method above is called never. I am quite confused...

  Is anyone of you know how to insert text in the virtual keyboard in the EditField? Is it possible to intercept these events?

  See you soon,.

  Beto

  The problem with keyChar and keyDown is that the char to insert depends on the keyboard layout, I didn't want to do something that it is already done by RIM.

  However, I have tried those overring however, but keyChar is never invoked, and keyDown gave place to a chariot double inserted in the editfield...

  In the end, I followed a suggestion made by @peter_strange in another post (I'll add the link if I managed to find it again) and put a FieldChangeListener on the edit field. When field changes, if the context is 0 (user action), I check if the text is changed and do what I have to do...

  Thank you.

• ALT + 2 or shift + 2 is not functional in Android EditField

  How do Alt + 2 OR shift + 2 functional in Android EditField component which Alt + 0-9 & SHIFT + 0 to 9 are respectively seized from 0 to 9. Only Alt + 2 & shift + 2 aren't seizes 2 in the EditField on all physical BlackBerry QWERTY devices such as the Q5, Q10, passport, P 9983 & classic.

  Is this a known issue? This hotfix is scheduled to be delivered in the future BlackBerry Runtime for Android update applications?

  This problem seems to occur when the inputType is set to 'numberPassword '. A bug report has been noted so I hope that the issue will be resolved in the future.

  Remove inputType = "numberPassword" will allow you to use the shortcut Alt + e to enter '2', but I guess you want to restrict the EditText to accept only numeric characters.

  At the same time (if you still want to accept numeric characters), do not hold down the shift or Alt to enter '2' with inputType = "numberPassword." You can simply press the 'e' '2 '.

• Display problem on 8310 and 8330

  Hello Experts,

  I have a blackberry app that works very well in all devices except 8310 and 8330.

  My application appears a screen (which has a LabelField and a BasicEditField) when a button is clicked. It works in all devices, but on the other hand, does not show 8310 and 8330 upward the LabelField and BasicEditField, it shows me just a white screen. But when I press 'Enter' on the blank screen, it triggers the LabelField FieldChanged event. How is it possible?

  May be that the two fields are hidden?

  If so, is to show all devices.

  I'm so confused.

  Please advice me on this.

  Thank you!!!

  I solved this problem by simply moving

  this.setFont (defaultFont);

  of the getPreferredWidth method to the constructor of the an EditField subclass.

  But I do not know the reasson for why it happens?

  Thank you for all.

  }
  

  Then I create: new AddEditField ("address:", cFont, maxSpace);  and add it to a screen.

  When I try to open this form. It is nullpointexception: the eclipse debugger show the info such as:

  AddEditField$ 4labelfield.paint line 385.

  Please help me to check the code. why it can run in 0 s 7.0 and before, only 7.1 has had this problem?

  Thank you

  Hi Flybrid,

  I checked at the time of your code,

  I am able to run your code by deleting page layout override methods in two fields of the label.

  The problem with the substitution of the method of layout in the spaceF and spaceF2 fields.

  But I can't explain why.

  I think that you can achieve the same thing by replacing getPrefferedWidth() and getPrefferedHeight() above the fields instead of page layout.

  Thank you.

• Non editable field change to highlight the problem

  Hi all

  I have an edit non editable field in my screen. In order to make the difference between editable and non editable field, I put the bottom of the field cannot be changed to light gray as in the code below:

     Border nonEditableBorder=BorderFactory.createRoundedBorder(new XYEdges(5, 5, 5, 5),Color.LIGHTGRAY,Border.STYLE_FILLED|Border.STYLE_TRANSPARENT);
  EditField textField=new EditField(EditField.NO_NEWLINE|EditField.FOCUSABLE|DrawStyle.RIGHT);
  textField.setBorder(nonEditableBorder);
  

  Now the field cannot be changed when I scroll the wheel to the right or left the text gets highlighted in white as shown in the image below:

  

  I don't want the text to highlight. Can anyone help me please with this. Thanks in advance.

  Kind regards

  S.A.Norton Stanley

  Hello

  Thank you. Overridding method drawFocus() and nothing doing, emphasis has been disabled on the fields and the white highlight was not. But once I reached the first or the last field of the white selection screen gets drawn again.  But the border I also assign the background of the field edit as shown below, and this solved my problem.

  Background bgNonEditable = BackgroundFactory.createSolidBackground(Color.LIGHTGRAY);
  textField.setBackground(bgNonEditable);

  I'm runing the Project One (first part) and record information to be stored, and then I WANT TO runing the project two (part two), but I received an error message telling me there are two same defined the class in the system, I try to change the class name of StoreInfo in two project, the last of error messge disappeared , instead of a CastClassException error, I am so sad...

  For a long time debugging I found some interesting things, look at the below codes to two projects, please read the name of the StoreInfor class, not StoreInfo.

   private MenuItem getItem = new MenuItem("Get", 110, 11) {
      public void run() {
        synchronized (store) {
          _data = (Vector) store.getContents();
          if (!_data.isEmpty()) {
            StoreInfor info = (StoreInfor) _data.lastElement();
          }
        }
      }
    };
  

  Now the _data class name is StoreInfo@xxxxxx (using _data.getClass () .getName ()) and class StoreInfo project two was renamed to StoreInfor, of course, I received a CastClassException error.

  I finished the story, and I need some guys to help solve this problem, tks a lot! ~

  Creating a descriptor application blackberry project and inside, choose library. Then, each project must refer to this library.

• Border and background for EditField

  I want to create EditField rounded, white but I use jre 4.5 Blackberry so I can't use:

  myEditField..setBorder(BorderFactory.createRoundedBorder(new XYEdges(2, 2, 2, 2),  0x35586C, Border.STYLE_SOLID));
  

  Because doesn't have class BorderFactory or border.

  I tried to draw a rectangle inside the paint method:

  myEditField = new EditField(){
              public void paint(Graphics g) {
                  super.paint(g);
                  int prevColor = g.getColor();
                  g.setColor( 0xffffff);
                  g.fillRoundRect(0, 0, getWidth(), getHeight(), 10, 10);
                  g.setColor(prevColor);
              }
          };
  

  I look fine, but the problem is that text inserted inside the EditField cannot be seen...

  Call super.paint () after you make your bottom paint. You cover it up with the fillRoundRect. Alternatively, if you are wanting just a border, you can use drawRoundRect().

• Button in the pop-up screen problem

  Hi all

  I did a pop-up screen in which there are two buttons and an EditField. Now, I am faced with very weird problem. First button that I added in my code doesnot seem to work. It doesnot clicking and the second button is working well, why is it so can any body help out me of this.

  I provided the code here: -.

  public class PinPopup extends PopupScreen{

  Hi Please help me in this

  Thanks in advance

  Why do you not use Horizontalfieldmanager for horizontal alignment.

  This is the code and it works fine.

  package com.winit.mobiads.ui.screens;

  }
           
  };

  _fieldManagerContext.Add (texts);
  _fieldManagerContext.Add (CancelButton);
  _fieldManagerContext.Add (sendButton);
  Add (_fieldManagerContext);

• clear the editfields by pressing the escape (back on the keyboard)

  Hi all

  I want to erase all editFields by pressing the ESC key. I know I have to implement a keyListener but what I don't know what else to say to clear the editFields.

  If anyone knows how to do this part please.

  Thank you

  I solved the problem. I'm poping the below screen, creating a new instance of this form and pushing it with the help of invokeLater

  / public class KeyListenerImplementation implements KeyListener
  {

  belowScreen of screen private;

  public boolean keyChar (key char, int status, int time)
  {

  If (key == Characters.ESCAPE & UiApplication.getUiApplication () .getScreenCount () > 2)
  {
  belowScreen = UiApplication.getUiApplication () .getActiveScreen () .getScreenBelow ();
              
  If (belowScreen instanceof XXScreen) {}
                  
  UiApplication.getUiApplication () .invokeLater (new Runnable() {}
  public void run() {}
  UiApplication.getUiApplication () .popScreen (belowScreen);

  UiApplication.getUiApplication () .pushScreen (new XXScreen));
  }
  });
  }

  }}

• Autosizing EditField

  I worked on an EditField autosize intake according to the paint and the value of MaxSize autour rectangle:

  the following code works fine online:

  EditField EF = new EditField ("",null, 8, EditField.FILTER_REAL_NUMERIC)

  {

  public layout zero (int width, int height)

  {

  int x = getFont ().getAdvance("0") * getMaxSize();

  Super.layout (x, getpreferredheight ());

  setExtent (x, getPreferredHeight ());

  } protected void paint (Graphics g)

  {

  g.setColor (Color.GRAY);

  g.drawRect (0,0,getWidth (), getHeight ());

  g.setColor (Color.BLACK);

  Super.paint (g);

  }

  };

  but when I create a class to extend the EditField, it does not work well (the width is set not right)

  public class SizeableEditField extends EditField

  {

  public SizeableEditField()

  {

  new EditField();

  }

  public SizeableEditField (long style)

  {

  new EditField (style);

  }

  public SizeableEditField (label As String, String initialValue)

  {

  new EditField (label, initialValue);

  }

  public SizeableEditField (String initialValue, label As String, style long ,int maxNumChars)

  {

  new EditField (label, initialValue, maxNumChars, style);

  }

  public layout zero (int width, int height)

  {

  int x = this.getFont (.getAdvance("0")) * this. getMaxSize(); / * get the size of the field in pixels of maxChar * /.

  Super.layout (x,this. getPreferredHeight()); / * layout with this space max in mind * /.

  setExtent (x,this. getPreferredHeight()); / * together extend the scope for manager.

  }

  protected void paint (Graphics g)

  {

  g.setColor (Color.GRAY);

  g.drawRect (0,0,this.getWidth(),. getHeight()); g.setColor (color.

  BLACK); Super.paint (g);

  }

  }

  call with:

  SizeableEditField EF = new SizeableEditField ("",null, 8, EditField.FILTER_REAL_NUMERIC);

  The rectangle is painted, but the size is still full hunting, so it seems that x is not calculated on the right.

  No idea why? My debugger will let me see the results of the Expression, os, it is difficult to understand.

  Thanks for help.

  Concerning

  I actually found the problem:

  I need to call super instead of a new EditField

  It works:

  public class SizeableEditField extends EditField

  {

  public SizeableEditField()

  {

  Super ();

  }

  public SizeableEditField (long style)

  {

  Super (style);

  }

  public SizeableEditField (label As String, String initialValue)

  {

  Super (label, initialValue);

  }

  public SizeableEditField (String initialValue, label As String, style long ,int maxNumChars)

  {

  Super (label, initialValue, maxNumChars, style);

  }

  public layout zero (int width, int height)

  {

  int x = getFont ().getAdvance("0") * getMaxSize(); / * get the size of the field in pixels of maxChar * /.

  Super.layout (x, getpreferredheight ()); / * layout with this space max in mind * /.

  this.setExtent (x, getPreferredHeight ()); / * together extend the scope for manager.

  }

  protected void paint (Graphics g)

  {

  g.setColor (Color.GRAY);

  g.drawRect (0,0,this.getWidth(),. getHeight()); g.setColor (color.

  BLACK); Super.paint (g);

  }

  }
