Hi

I have made a custom edit filed, and i want to have a filter of alpha numeric characters for it.

i do have an Integer -- for numeric

and for alphabets:: lower case and upper case filter.

How can i set all 3 for one filed, or make a custom filter like wise.

Please help me, Thanks!

Hi all,

I'm also facing the same problem. I've tried with different ways but No Luck!

Case 1:

BasicEditField field = new BasicEditField("Input: ", "", 100, 
       BasicEditField.FILTER_UPPERCASE | BasicEditField.FILTER_LOWERCASE | BasicEditField.FILTER_INTEGER);

Case 2:

BasicEditField field = new BasicEditField("Input: ", "");        
field.setFilter(TextFilter.get(TextFilter.UPPERCASE | TextFilter.LOWERCASE | TextFilter.INTEGER));

Actually, no difference between two cases.

Is it possible by setting only STYLE property or have to write a custom EditField component?

Help me with your valuable feedback!

Thanks,
ARIF

frankly speaking, I'm not sure what result you are trying to achieve, but we played TextFilter interface and it worked.
We define custom implementation of TextFilter and use method BasicEditField.setFilter() to define our custom implementation for edit field.

Thanks Skipper_Joe!

I want to design a custom EditField which will accept only Integer text, Uppercase, and Lowercase alpha characters for input.

A Code snippet would help.

Here is the sample:

import net.rim.device.api.ui.UiApplication;
import net.rim.device.api.ui.text.TextFilter;
import net.rim.device.api.ui.component.BasicEditField;
import net.rim.device.api.ui.container.MainScreen;

public class TFilterApp extends UiApplication
{
    private static class Form extends MainScreen
    {
        public Form()
        {
            setTitle("Test app");
            BasicEditField field = new BasicEditField("Enter data:", "");
            field.setFilter(new TextFilter()
            {

                public char convert(char c, int i)
                {
                    return c;  // don't convert anything here
                }

                public boolean validate(char c)
                {
                    return (Character.isDigit(c) || Character.isLowerCase(c) || Character.isUpperCase(c));
                }
            });
            add(field);
        }
    }


    TFilterApp()
    {
        pushScreen(new Form());
    }

    public static void main(String[] args)
    {
        TFilterApp app = new TFilterApp();
        app.enterEventDispatcher();
    }
}
