J2ME in a Nutshell

Name

TextBox

Synopsis

TextBox is a full-screen text editing component that has almost the same programming interface as TextField. Apart from the fact that a TextBox is visually represented as a multi-line control and occupies the whole screen whereas TextField usually appears as a single line in a Form, the only real difference between these two controls is the fact that TextBox does not notify content changes to a listener. Application code should add a Command to the TextBox to allow the user to request that its content be processed.

                  
public class TextBox extends Screen {  
// Public Constructors
   public TextBox(String title, String text, int maxSize, 
        int constraints);    
// Public Instance Methods
   public void delete( int offset, int length);  
   public int getCaretPosition();  
   public int getChars( char[] data);  
   public int getConstraints();  
   public int getMaxSize();  
   public String getString();  
   public void insert( String src, int position);  
   public void insert(char[] data, int offset, 
        int length, int position);  
   public void setChars(char[] data, int offset, 
        int length);  
   public void setConstraints( int constraints);  
   public int setMaxSize( int maxSize);  
   public void setString( String text);  
   public int size();  
}
