• Assign a spacing equal to the fields in the horizontal field Manager

  Hello

  I add a number of vertical field managers to a horizontal field Manager. Each manager of vertical field has a text with an image under. The text varies in width images in each vertical field Manager seem to have a different amount of space between them. Is there a way to remedy this situation? Joined a raw image in the way that message on the screen. How can I get the same amount of space between each area of the rectangle?

  Thank you

• How to add the line of separation in the horizontal field Manager

  How do I solve this problem

  Thank you

  You can also do this by substituting your HorizontalFieldManager sublayout() method.

  As:

          h = new HorizontalFieldManager()
          {
              protected void sublayout( int maxWidth, int maxHeight )
              {
                  int width = Display.getWidth();
                  int height = 30; //height of the manager
  
                  super.sublayout( width, height);
                  setExtent( width, height);
              }
  
          };

• Align the HorizontalFieldManager field

  Hello

  I have a few problems right align my custombutton in a HorizontalFieldManager.

  It's a pretty simple code, but it does not work!

  My Manager to take full width but my field stuck on the left.

  My custom button (ButtonImageGadget) simply extends the field.

  Y at - it a way to make it works or we have an absolute positioning with layoutChild?

  Thanks for your help

  Its a bug in blackberry jde, try the following:

  1. If you want to add only the unique field in this Manager, and then create the domain Vertical instead of horizontal area manager Manager.

  2. If you have two or fields, and all this must be right aligned, and then create a VerticalFieldManager (Manager.USE_ALL_WIDTH |) Manager.FIELD_RIGHT), create a horizontal field Manager add all the fields to this horizontal Manager, and addition of horizontal to vertical Manager Manager

  3. If you have several fields and these should be aligned differently, then please create a horizontal field Manager add fields to this Manager, you want to align to the left. create a verticalfieldmanager using field_right and the entire width. Create fields in this handler with Field.RIGHT or Field.HCENTER style according to your needs.

  Need your valuable comments and suggestions. Please help me.

  I think that there is a bug in the sublayout (your HorizontalFieldManager 0 mode.  Given that the code did what I think WHAT HFM will do anyway, I recommend that you try to do this with a standard HFM, using this style:

  Manager.HORIZONTAL_SCROLL | Manager.HORIZONTAL_SCROLLBAR

  Let us know how you go.

  When I have more time I'll explain the bug, but if you want to investigate something, be aware that the maximum size that you can use in setExtent are the values that are passed to sublayout.  Compare the width as you try to define in setExtent whose width is increased.

  How to align the Hcenter fields in VFM? its giving problem

  solution on mine! years of posting for reference...

  what I did earlier.

  I wanted to have a manager of fixed size (maximum size) and put fields here, during an aliging then using stylebit it did not work. I used sublayout and fixed to what extent a perticular dimension

  resovled doing problem.

  It is not sufficient (or necessary) to if you want to use sublayout to have a fixed size, if you use the alignment, bcz setting hardcodedly properties, the other model overridden, so u must override the methods 'getPrefferedWidth & height', not the two held all the time, but according to the needs, if you want to:-alignment, you can try only method "width" and comparable to V-alignment. I included these methods and found that half of my UI related issues would have resolved more easily, if I tried this previously.

• problem with the vertical field Manager

  Hello

  My application has a screen. On this, I add a Senior Manager vertical field. I add new labelfields dynamically to this vertical field Manager.  When I give the text in the constuctor of the etiquette field, each of them is the fine display. But when I tried to draw the text to the painting, it does not appear.

  Here is my code...

  vfm = new VerticalFieldManager(VERTICAL_SCROLL | FOCUSABLE);
          for (int i = 0; i < 4; i++) {
              index = i;

          add(vfm);
  

  Please help me find a solution.

  First of all, stop saying that it is VerticalFieldManager who has done something bad for you. It has nothing to do with it.

  You use the index in your LabelField painting method. Use paint value is the current value of the index at the time of the painting. Painting happens way after you have created all your LabelFields, when the index stopped to change and has the last value of the loop variable (in your case, it's 3).

  This, as well as LabelFields width zero (that you seem to have supported) so are the problems of your original code. Store the value of i in your LabelField somehow if you insist on using the table values. If only check out you them once and do not change them, consider creating your LabelFields with the text from this displayString table.

  Even better: as you do not use the LabelField paint, why not create a custom field received a text and paint your smileys and all? Of course, you have to implement available as well, but it's useful even when your smileys will take a different width than the corresponding symbols.

  To summarize: your current approach is bad. Take a step back, work on the design, and then implement.

• some fields shows don't not in horizontal field Manager

  Hello

  I try to have several lines with label, number and units. For example temperature, 17, F. When the application draws lines the label is visible, but the units are not. No idea why? Maybe it's pushing too far to the right, and they are off the screen? I use the Simulator for this.

  I tried to limit the size of the label field with no luck and I have also experimented with eliminating the label field, which causes the units to appear but then of course I still need labels. My code is below:

  Private HorizontalFieldManager generateMeasurementField (label As String, String unitLabel) {}
  Line HorizontalFieldManager = new HorizontalFieldManager();
  Field TextField = new TextField();
  field.setEditable (false);
  field.setLabel (label);
  UnitField TextField = new TextField();
  unitField.setText (unitLabel);
  unitField.setEditable (false);
  Row.Add (Field);
  Row.Add (unitField);
          
  next row;
  }

  And then I subsequently add each row to the Senior Manager.

  TextField is eager for width: it occupies the entire available width (do not leave anything for the rest of the fields). If you do not need to edit the text, use LabelField instead: they are economical and meet only as needed.

  But now I want to do a custom in horizontalFieldManager, paint using the page horizontal scrolling top given adjustment.

  Thank you

  It seems that you want to have background - repeat some almost text in your example. Then move it out of the subpaint and by the paintBackground-, you will not have to invoke any Super... here.

  Now when you say that a horizontal scrolling does not work, what exactly do you see? What do you see? Do you have enough focusable fields in your handler for scroll? Have HORIZONTAL_SCROLL style bit set?

• effect of animation for horizontal field Manager

  Hello
  I have three willing fieldManagers horizontally in the content of

  average fieldmanager will change on click of a button

  is it possible to apply slide in French - sliding effect to these content?

  I don't want to do the new screen n again?

  Wrap the Middle Manager in a HorizontalFieldManager (HORIZONTAL_SCROLL). When you want to remove the old content and slide into the new, follow these steps:

  (1) adds the new content the HFM;

  (2) an animation slide to the left edge of the old content (probably 0) up to the left edge of the new (getLeft() returns). Use the method suggested by Peter;

  (3) once the animation finished, remove old content and setHorizontalScroll on the HFM wrapping to 0 (since the new content now starts it).

  hfm.setBackground(BackgroundFactory.createSolidBackground(Color.GREEN));
  

  

  Please take a look at this code. I expect to do the following: add time to the left of the horizontal field Manager, and then add a field in the center of it and in the right part. The first two tasks succeeded. But what is the problem with the third label, i.e. with "2"? Why would she be placed in the next line?

  Please tell me what I'm doing wrong...

  hfm = new HorizontalFieldManager(USE_ALL_WIDTH)
          {
              protected void sublayout(int maxWidth, int maxHeight)
              {
                  super.sublayout(maxWidth, maxHeight);
                  setPositionChild(this.getField(0),0,0);
                  setPositionChild(this.getField(1), (this.getWidth() - (labelField1.getWidth()))/2, 0);
                  setPositionChild(this.getField(2), (this.getWidth() - labelField2.getWidth()), 0);
              }
          };
          Date now = new Date();
          SimpleDateFormat sdf = (SimpleDateFormat) DateFormat.getInstance(DateFormat.TIME_LONG);
          String time = sdf.format(now);
          LabelField timeLabelField = new LabelField(time);
          hfm.add(timeLabelField);
          labelField1 = new LabelField("1", LabelField.FIELD_HCENTER);
          labelField2 = new LabelField("2", LabelField.FIELD_RIGHT);
          hfm.add(labelField1);
          hfm.add(labelField2);
          hfm.setBackground(BackgroundFactory.createSolidBackground(Color.RED));
          add(hfm);
          timeLabelField.setBackground(BackgroundFactory.createSolidBackground(Color.GREEN));
  

  Use this code, you will get the desired result.
