Question

i am using an ObjectChoiceField in blackberry now. I have items in String array like “a”, “abc”, “abcdefg” etc. The application automatically sets the width based on the width of the choice items. I want the dropdown window in ChoiceField having width static which can hold the largest entry in the string array.

My question is, Can i set the dropdown window size? if yes, How could i set the width of the DropDown window (which displays all choice items of your choice field)?

Answer 1

i had created a custom choice field..

import net.rim.device.api.ui.component.ObjectChoiceField;

/*
 * The MyChoiceField is actually an extended class of ObjectChoiceField.
 * In this, the design of an ObjectChoiceField is overloaded with providing some additional 
 * tasks is done. It includes a constructor and a Layout methods.
 * In that Layout method the design for the ObjectChoiceField is overrided... 
 */
public class MyChoiceField extends ObjectChoiceField 
{

    public MyChoiceField(String label ,Object[] choices) 
    {
        super(label, choices);
    }


    protected void layout(int width, int height) 
    {
        setMinimalWidth(width/2-62);
        super.layout(width, height);
    }

}

Now i got it…

thanks….
