• How to improve the search function on a VerticalFieldManager that contains custom managers

  I have a screen with a VerticalFieldManager for a list of custom managers holding.

  The screen also contains an EditField that behaves like a search field, when the user enters the text, my app looping through an array of custom managers and compares the text entered with the text of all managers in the table.

  If the text of a Manager matches the input string, I add this handler to the VerticalFieldManager.

  Here are the relevant parts of my code:

  EditField _editField.
  TempBeanPlaces [] _placesList;
  VerticalFieldManager _vfmCellPlaces;

  ....

  This is the constructor of TemBeanPlaces:

  public TempBeanPlaces (String pPlaceName, CellPlaceManager pCellPlaceManager) {}
  placeName = pPlaceName;
  cellPlaceManager = pCellPlaceManager;
  }
  ...

  And this code handles the research:

  _editField.setChangeListener (new FieldChangeListener() {}
  ' Public Sub fieldChanged (field field, int context) {}
  String text = _editField.getText () .toLowerCase ();
  _vfmCellPlaces.DeleteAll ();
  for (int i = 0; i)< _placeslist.length;="" i++)="">
  TempBeanPlaces tempBeanPlaces = _placesList [i];
  If (tempBeanPlaces.getPlaceName () .toLowerCase (). IndexOf (Text)! = -1) {}
  _vfmCellPlaces.Add (tempBeanPlaces.getCellPlaceManager ());
  }
  }
  updateLayout();
  }
  });

  This works well when the _placesList table is not too big (length of 50, for example), otherwise the application becomes too slow.

  How can I optimize my code for large quantities of custom managers? For example, in the case, the table contains 600 elements.

  I really need to improve this feature. I just read on the ListField in BlackBerry, but since I have this code, maybe I need to rewrite all with ListFields.

  Thanks in advance!

  The biggest problem with update fields as it is time to layout, fields that are added.  If you add such a moment, then each addition will cause a layout.  Instead, you use addAll to add an array of items, or you can also add all of your items to a single Manager, and then add the Manager.  Then the layout occurs only once.

  In your code, the option would be to add managers selected to a vector, transform the vector into an array, then use addAll.

  You don't need the updateLayout().

  That said, more you add them fields, more processing will be available anyway, then perhaps you are trying to add more elements than even this optimization will execute quickly.  If this optimization does not work enough, then you will need to look in a different way, say 'paging' results, then the display doesn't show that the top 25 and the user can 'add more '.  This 'Exchange' is a good approach in my experience, because users will rarely scroll 25, when they can make another research that could give them better results.

  Finally, and to be on par with the comment of Simon, ListField is an extremely effective area because it is a unique field, so layout is easy, and he's not trying to paint lines until they are actually displayed on the screen.  So in your case, you have three options:

  (1) addAll

  (2) paging

  (3) ListField

  Let us know how you go.

• Several items in a VerticalFieldManager

  Hello

  I am trying to create a simple screen with images inside. To do this, I'm creating a VerticalFieldManager (although my understanding of the screen itself acts like one) and then to add bitmapfields on opposite corners. However, I believe that only the first bitmap that I add to the screen is displayed. What happens here? I know that the images load properly because I changed the order in which they appear, and it is always true that only the first added to the charges.  Any help is appreciated. Here is my code:

  SerializableAttribute public class MyScreen extends {full screen

  public MyScreen() {}
  VerticalFieldManager _mainManager = new VerticalFieldManager();
  _mainManager.setbackground (BackgroundFactory.createSolidBackground (0));
  Add (_mainManager);
  BitmapField _bitmap;
  Image bitmap _mainmenutop;
  _Cursor bitmap image;
  BitmapField _bitmap2;

  _bitmap = null;
  _bitmap2 = null;

  _mainmenutop = Bitmap.getBitmapResource ("mainmenutop.png");
  _bitmap = new BitmapField (_mainmenutop, BitmapField.TOP
  | BitmapField.RIGHT);
  _cursor = Bitmap.getBitmapResource ("cursor.png");
  _bitmap2 = new BitmapField (_cursor, BitmapField.BOTTOM
  | BitmapField.LEFT);

  _mainManager.Add (_bitmap);
  _mainManager.Add (new SeparatorField());
  _mainManager.Add (_bitmap2);

  }

  }

  Incredibly, the main problem is Field.TOP in your _bitmap!

  I knew that VerticalFieldManager was working well with Field.TOP and Field.BOTTOM, but it was really unexpected.  I wonder how many experts could predict who...

  Then remove the style bits in your Field.TOP _bitmap and make sure that you do not use VerticalFieldManager or screen with VERTICAL_SCROLL (or Field.BOTTOM will send your field up to infinite virtual).

  I am trying to add textfield for this account only, but it did not add.

  pls help me if anyone knows?

  He could have added. If either CustomLableFeild or CustomManager uses the full display width, then _vmanager [0] uses the full display width. In this case, the rest of the fields of _row [0] is positioned beyond the right edge of the screen. Without horizontal scrolling, it's almost as if these fields were not there.

  What classes CustomLableFeild and CustomManager extend? What style value when they are built?

  How to align the center of iHFM horizontally in the iVFM?

  Have not tried this, but you may be lucky if you set the style on your RTF as USE_TEXT_WIDTH where the RTF is expanding to the entire width of the available space and which actually look like everything is left aligned when it actually happens in the whole of the entire screen.

• Verticalfieldmanager large parchment

  I have a screen, on which I create a scrolling box like this:

  scrollArea = new VerticalFieldManager(Manager.USE_ALL_HEIGHT |) Manager.USE_ALL_WIDTH |
  Manager.VERTICAL_SCROLL | Manager.VERTICAL_SCROLLBAR);

  I add several VerticalFieldManagers to the scrolling area. I have an optimization of resources which is very large (several times larger than the physical screen (vertically)).

  My problem is when I scroll on devices such as the 9700.

  As changes in development by the great VFM to another, the page scrolls as the focus changes, but only to the top of the next optimization resources. It is never possible to see the "means" of the great value for money.

  How do I scroll through several VFMs smoothly so that I can see everywhere in the fields on the screen?

  What type of field - what is big enough?

  There are a variety of solutions for this, and the best one will depend on the type of field and the scroll requires you.

  For example:

  Here's a possible solution for a large image.

  And for a great LabelField, you can convert it into a RcihTextField.

• Quick question PopupScreen VerticalFieldManager:

  I'm building a contextual menu screen custom that displays two text fields, an OK and CANCEL button.  I use the VerticalFieldManager as the Manager.  I used the styles Field.FIELD_RIGHT and Field.FIELD_LEFT for the OK and CANCEL buttons to the OK button on the left side of the dialog box (under the text fields) and the button CANCEL on the right side.

  The only problem I have with the screen, it is that, since I'm on the VerticalFieldManager, the OK and CANCEL button are on different lines.  Is there a style of field that will put them on the same line, even if I use the VerticalFieldManager?  Or should I use a different Manager.

  Thanks in advance...

  Hi mlisaoverdrive,

  By defalt, popupscreen uses the vertical area manager, so that you can do is put two buttons in a HorizontalFieldManager. Then add the Manager of horizontalfield on the screen.

  Wait I'm confused... According to the docs, you must provide a handler delegate for PopupScreen.  Does not mean that it is not a default Manager?

  Sorry my bad, I was talking about the screen. in any case, just use the VerticalFieldManager as your cost of Manager. Then put your buttonFields in a single horizontal FieldManager. then after the addition of some fields in your form, add the horizontalfieldmanager in the last.

• Static background with VerticalFieldManager

  Hello, I would like to set up a background image for my application, where it must not move even when the user scrolls... I found the following code on the internet for this type of Manager:

  package com.kruger.workflow.gui;
  
  import net.rim.device.api.system.Bitmap;
  import net.rim.device.api.system.Display;
  import net.rim.device.api.ui.Graphics;

  public class BGVerticalFieldManager extends VerticalFieldManager {
      Bitmap mBgBitmap = null;
      int mBgWidth = -1;
      int mBgHeight = -1;
      int mBgX = -1;
      int mBgY = -1;
  
      public BGVerticalFieldManager(Bitmap background) {
          super(USE_ALL_WIDTH | USE_ALL_HEIGHT | VERTICAL_SCROLL
                  | VERTICAL_SCROLLBAR);
          mBgBitmap = background;
          mBgWidth = mBgBitmap.getWidth();
          mBgHeight = mBgBitmap.getHeight();
          mBgX = (Display.getWidth() - mBgWidth) >> 1;
          mBgY = (Display.getHeight() - mBgHeight) >> 1;
  
      }
  
      protected void paintBackground(Graphics graphics) {
          paintBackgroundBitmap(graphics);
          invalidate();
      }
  
      private void paintBackgroundBitmap(Graphics graphics) {
          if (null != mBgBitmap) {
  
              int x = mBgX
                      + getHorizontalScroll();
  
              int y = mBgY
                      + getVerticalScroll();
               graphics.drawBitmap(x, y, mBgWidth, mBgHeight, mBgBitmap, 0, 0);
          }
      }
  }
  

  However, does not work... I get the following results:

  

  

  As you can see the image begins to scroll backwards...

  The use of this Manager is:

  Bitmap bitmap = Bitmap.getBitmapResource("1.jpg");
          add(mContainer = new BGVerticalFieldManager(bitmap));
          for (int i = 0; i < 100; i++) {
              mContainer.add(new LabelField("List item #" + String.valueOf(i)));
              mContainer.add(new SeparatorField());
          }
  

  Although no result so far... When debugging the code, I noticed that this line:

  if (null != mBgBitmap) {
  
              int x = mBgX
                      + getHorizontalScroll();
  
              int y = mBgY
                      + getVerticalScroll();
               graphics.drawBitmap(x, y, mBgWidth, mBgHeight, mBgBitmap, 0, 0);
          }
  

  Always returns 0 for both a XY is not assumed that getVerticalScroll or getHorizontalScroll must return aware of gap between the container Manager.? How can I fix this?

  Thank you very much.

• Custom Manager not correctly rendered after having been added to a VerticalFieldManager in BlackBerry

  I have a VerticalFieldManager that renders a white round rectangle.

  This is the code:

  VerticalFieldManager _vfmBackground = VerticalFieldManager(Manager.NO_VERTICAL_SCROLL | nouveau)
  Manager.NO_VERTICAL_SCROLLBAR | Manager.USE_ALL_WIDTH) {}
  public void paint (Graphics graphics)
  {
  Graphics.Clear;
  graphics.setColor (Color.WHITE);
  graphics.fillRoundRect (10, 10 460, 400, 25.25);
  Super.Paint (Graphics);
  }

  protected void sublayout (int maxWidth, maxHeight int)
  {
  displayWidth = int (Display.getWidth ());
  displayHeight = int (Display.getHeight ());

  Super.sublayout (displayWidth, displayHeight);
  setExtent (displayWidth, displayHeight);
  }

  };

  Then, I created a custom handler named BaseHeaderBlueScreen class that renders a blue rectangle:

  public void paint (Graphics graphics)
  {
  Graphics.Clear;
  graphics.setColor (610212);
  graphics.fillRect (20, 0, Display.getWidth (), Display.getHeight ());
  Super.Paint (Graphics);
  }

  protected void sublayout (int maxWidth, maxHeight int)
  {
  int displayWidth = (Display.getWidth () - 40);
  displayHeight = int ((Display.getHeight () / 2))-90;

  super.setExtent (displayWidth, displayHeight);
  }

  Finally, I add this handler to the VerticalFieldManager with the white rounded rectangle:

  BaseHeaderBlueScreen _vhbs = new BaseHeaderBlueScreen (environment, textBottom, 0);
  _vhbs.setPadding (20,30,0,0);
  _vfmBackground.Add (_vhbs);

  That's how the rectangle blue should be displayed in the white rectangle.

  

  But it is how the blue rectangle is currently displayed (note the gray space on his left side):

  

  How do I do to make the blue rectangle, exactly like you want (without the left border gray)?

  Thanks in advance!

  Hi thanks, I just removed object calls these two methods clear() and now it works!

• verticalfieldmanager will not be available to the child

  private VerticalFieldManager vfm = new VerticalFieldManager( Manager.VERTICAL_SCROLL | Manager.VERTICAL_SCROLLBAR | Manager.FIELD_HCENTER) {
  
          int width = Display.getWidth();
          int height = Display.getHeight() - 80;
  
          public void sublayout(int maxWidth, int maxHeight) {
              super.sublayout( width, height);

              setExtent( width, height);
          }
      };
  

  I had a display issue of the provision of the child for verticalfieldmanager.

  available to the child focuses not horizontal on the Manager when creating a fixed size for the Manager.

  someone knows the solution?

  setpositionchild will not solve the problem.

  This code, I think he need to better understand what a Manager should do in the sublayout and the constraints that it works under.

  Let's look at your code:

  ' public void sublayout (int maxWidth, maxHeight int) {}
  Super.sublayout (width, height);
  bagi int = (Display.getWidth () - this.getField (0) .getWidth ()) / 2;
  Field = this.getField (0);
  setPositionChild (field, bagi, 0);
  setExtent (width, height);
  }

  There are a lot of points to note, please bear with me:

  You specify your Manager with Manager.FIELD_HCENTER.  It's trying to tell the Manager you add this in (call it the father Manager), that this child, the Manager must be centered horizontally.  So the father will help this child Manager, then determine how wide the child Manager, then to determine the width of the father is the Director and finally position the child in the Center Manager.  Here, the assumption is that this Manager will have limited space on each side.  If she has in fact that, will depend on the type of Manager, and other fields in it, and how have specified you them.  But this setting in itself might solve your problem.  The fact that it is not suggests there is another problem elsewhere.

  Note that the space provided for the Manager is the maximum that he can use.  As you try to limit the width and the height, in case you, the area you have to play with is bounded by

  (1) a minimum of maxWidth and Display.getWidth () - 80, width and

  (2) minimum of maxHeight and Display.getHeight)

  You should check this before using a value for your treatment.

  You call super.layout (), then actually ignore everything he does, except that it will be layout all fields, this value must be precise:

  this.getField (0) .getWidth)

  But what we don't know is how you asked that area be set up.  For example, they say this field of USE_ALL_WIDTH.  In this case the value of bagi was 0 and means that this Manager cannot hope 'centre' field.

  I recommend that you consult these KB articles for more information on how to program manager.

  http://supportforums.BlackBerry.com/T5/Java-development/create-a-custom-layout-manager-for-a-screen/...

  http://supportforums.BlackBerry.com/T5/Java-development/how-to-extend-Manager/Ta-p/446749

  In this particular case, you can actually Center a field in a fair value for money using the FIELD_HCENTER style.  If it does not, then it is probably a problem with the field as an EditField who always takes the entire width.  You will not solve this using your own.

  In addition, in this case, we can actually solve this problem for you.  You can debug this further and determine exactly why the field is not being centered.  Is it because bagi is 0 for example?  I hope that knowing that you will have to review the articles once again will help to debug this.
