Java Development

Ok, I went back to the original code from http://supportforums.blackberry.com/t5/Java-Development/TextBoxField-revisited/ta-p/548410 and just added my methods (see below).

package uid.rim.uidchecker;

import net.rim.device.api.ui.Color;
import net.rim.device.api.ui.Graphics;
import net.rim.device.api.ui.Manager;
import net.rim.device.api.ui.component.EditField;
import net.rim.device.api.ui.container.VerticalFieldManager;

public	class TextBoxField extends Manager {
    int managerWidth;
    int managerHeight;

    private VerticalFieldManager vfm = new VerticalFieldManager(VERTICAL_SCROLL | VERTICAL_SCROLLBAR | USE_ALL_WIDTH | USE_ALL_HEIGHT);
    private EditField editField = new EditField("", "", EditField.DEFAULT_MAXCHARS, FOCUSABLE);

    TextBoxField(int width, int height, long style) {
        super(style | NO_VERTICAL_SCROLL | NO_HORIZONTAL_SCROLL);
	managerWidth = width;
	managerHeight = height;
		
	add(vfm);
	vfm.add(editField);
    }

    TextBoxField(int width, int height) {
        this(width, height, 0L);
    }
		
    public String getText() {
	return editField.getText();
    }

    public int getPreferredWidth() {
        return managerWidth;
    }

    public int getPreferredHeight() {
        return managerHeight;
    }
    
    public void setFocus() {
   	 	editField.setFocus();
    }
    
    public void setText(String value) {
    	 editField.setText( value );
         editField.setCursorPosition( editField.getText().length() );
    }
    
    public void writeLine(String value) {
    	editField.setText( editField.getText() + value + "\n" );
    }
		
    protected void sublayout(int w, int h) {
        if (managerWidth == 0) {
            managerWidth = w;
        }
        if (managerHeight == 0) {
            managerHeight = h;
        }
	int actWidth = Math.min(managerWidth, w);
	int actHeight = Math.min(managerHeight, h);
	layoutChild(vfm, actWidth - 2, actHeight - 2); // Leave room for border
	setPositionChild(vfm, 1, 1);	              // again, careful not to stomp over the border
        setExtent(actWidth, actHeight);
    }
		
    protected void paint(Graphics g) {
	super.paint(g);
	int prevColor = g.getColor();
	g.setColor(Color.BLACK);
	g.drawRect(0, 0, getWidth(), getHeight());  // draws border
	g.setColor(prevColor);
    }
}

 Now the left and right borders do not appear and the original problem remains.

Well, you'll need to debug the problem - I don't see what's wrong. As I've suggested, at least report exceptions. And try to make the debugger work for you - it is an invaluable tool sometimes.

It really looks to me like the new lines are somehow being ignored after the scan.  I have put a question to the vendor of the barcode library about this.
