• a transparent sliderfield

  Hello

  I have a popup screen that contains a sliderfield. However, the background image can not be transparent, when I put a transparent png in it.

  Thanks in advance.

  Code:

  Have we not need to see the cod SliderField to see how it uses the image?  Or am I stupid?

  You don't seem to want to show us this code, then maybe you can reproduce the problem with an another field that uses only the png as the background?

  I assume that your png is actually transparent (or parts of it are)?  Have you tried just a BitmapField with this picture to know if there is?

• How to get the Position value current sliderField

  I'm on SliderField for example following

  http://www.BlackBerry.com/knowledgecenterpublic/livelink.exe/fetch/2000/348583/800332/800505/800608/...

  But the problem is I want to get her current state value after each trip for this I use this code

  but it is not updated LabelField with its current value

  protected boolean touchEvent (TouchEvent message)
  {
  System.out.println ("method called touch");
  int vall = sixthSlider.getNumStates ();
  String txt = Integer.toString (vall);
  lbtitle.setText (txt);
  fieldChangeNotify (1);
  Returns false;
  }

  Two tips:

  (1) you use getNumStates where you call getState!

  (2) do not substitute the touchEvent at all. SliderField is a field almost entirely executed, so that she calls fieldChangeNotify on the changes of State. Set up a FieldChangeListener, configured to listen on this field and put your logic inside fieldChanged.

  Good luck!

• Java blackBerry Slider Bar

  HII, I created a scroll bar by referring to the example:https://github.com/blackberry/Samples-for-Java/blob/master/Advanced%20UI/src/com/samples/toolkit/ui/...,.

  hereby I am slider properly displayed on my screen, but my problem is next to the slider bar, I want to show a play/pause button, so i used the code below:

  SerializableAttribute public class UIExampleSliderScreen extends UIExampleScreen {}
  private ButtonField _startPlayingButton;
  Private ButtonField stop;

  private ButtonField facebookButton;

  public UIExampleSliderScreen() {}
  Super (0);
  _startPlayingButton = new ButtonField ("Play");
  stop = new ButtonField ("Stop");

  facebookButton = new ButtonField ("Facebook");
  facebookButton.setMargin (5, 5, 5, 5);
  HorizontalFieldManager Manager = new HorizontalFieldManager();

  setTitle ("cursor screen");
  final SliderField cursor;
  cursor = new SliderField)
  Bitmap.getBitmapResource ("slider2_thumb_normal.png"),
  Bitmap.getBitmapResource ("slider2_progress_normal.png"),
  Bitmap.getBitmapResource ("slider2_base_normal.png"),
  Bitmap.getBitmapResource ("slider2_thumb_focused.png"),
  Bitmap.getBitmapResource ("slider2_progress_focused.png"),
  Bitmap.getBitmapResource ("slider2_base_focused.png"), 20,
  0, 16, 16, FOCUSABLE).
  slider.setPadding (20, 20, 20, 20);

  slider.setBackground (BackgroundFactory
  .createSolidBackground (0xD3D3D3));

  Manager.Add (Slider);

  Manager.Add (facebookButton);

  Manager.Add (_startPlayingButton);
  Manager.Add (Stop);
  Add (Manager);

  }

  }
  }

  (1) I am able to show only the slide bar, my custom buttons are not displayed?

  (2) the sliding bar is displayed on screen, fully, how can I reduce the length of my slide Bar?

  the field of cursor seems to be designed to occupy the entire width:
  public int getPreferredWidth()
  {
  Return Integer.MAX_VALUE;
  }

  you have to change this, or replace available to the Manager.

  I want to ban the change of direction of screen, but it will not work in os 6.0!

  someone help me?

  Thank you.

  Thank you for what you have done. I must say that you're a serious and good man.

  If you can't reproduce by following the path, then I'll accept this as resolved, then do it myself.
