moving on text of labelfield in blackberry - blackberry

i have large data in label field and using FOCUSABLE on it makes the whole data selected at once.Scrolling down focus goes to next LabelField.Is ther a way to move on text of LabelField line by line
Eg: my label field is
String tenlines="line
line 2...
line10"
LabelField f= new LabelField(tenlines);

You can use RichTextField
String tenlines="line
line 2...
line10";
RichTextField detailField = new RichTextField(tenlines)

BlackBerry API 6.0. How to make a LabelField wider (to make it stop enforcing new lines)?

I have a class which extends LabelField to set font and color.
I have 2 such custom LabelFields and they display some strings of text. Those Strings are rather short, about a dozen symbols long.
The problem is that these custom LabelFields enforce new lines. They break my strings and display them in 2 lines instead of only 1 (no matter if a String is 6 or 12 characters long).
How to make these LabelFields stop enforcing new lines?
I need to have one line stay one line.
Update:
I have found the reason of that problem.
The problem was on another level, - in the process of calculation of width and height for my popup Screen which contained those LabelFields.
you can use the style LabelField.ELLIPSIS to force the single line.
like
LabelField l = new LabelField("your text",LabelField.ELLIPSIS);

EditField in Black Berry

I want to create the EditField which allow Numeric Values, Comma and other values are ignore in Blackberry.
So How I can achieve this by programming code ?
Thanks.
It can be achieved by using the EditField class with the Four arguments according to your need.
EditField ef = new EditField(0, "0", 3, EditField.FILTER_NUMERIC)
Add this field to a screen or a manager
The above code would make the field accept only the integer values. And if it is a Virtual keypad, it would not even show other characters/aplhabets on the keypad
Hope this solves your problem.
Keep Coding
Cheers !!
use filter for this.....
_numberEditField = new EditField(_name, "");
_numberEditField.setFilter(TextFilter.get(TextFilter.NUMERIC));
add(_numberEditField);
