Blackberry Java: TextField *without* the caret?

Question

I want a non-editable TextField (or a subclass) that doesn't even have the caret displayed. Alternatively, I want a multiline LabelField. Is any of these possible?

Answer 1

TextField without focus cursor

TextField readOnly = new TextField(NON_FOCUSABLE);
readOnly.setText("Read only, no carret");
add(readOnly);

TextField drawFocus override

If text is too large to fit the screen, you can override drawFocus method in TextField, so scrolling will be available:

TextField readOnly = new TextField(READONLY)
{
    protected void drawFocus(Graphics graphics, boolean on) {}
};

TextFields, separated with NullFields

Other option is to split TextField into several, separated with NullFields:

class Scr extends MainScreen {
    public Scr() {

        String text = "Lorem ipsum dolor sit amet, consectetuer "
                + "adipiscing elit, sed diam nonummy nibh euismod "
                + "tincidunt ut laoreet dolore magna aliquam erat "
                + "volutpat. Ut wisi enim ad minim veniam, quis "
                + "nostrud exerci tation ullamcorper suscipit "
                + "lobortis nisl ut aliquip ex ea commodo consequat. "
                + "Duis autem vel eum iriure dolor in hendrerit in "
                + "vulputate velit esse molestie consequat, vel "
                + "illum dolore eu feugiat nulla facilisis at vero "
                + "eros et accumsan et iusto odio dignissim qui "
                + "blandit praesent luptatum zzril delenit augue "
                + "duis dolore te feugait nulla facilisi.";

        text = addScrollText(text, 150);
    }

    private String addScrollText(String text, int partSize) {
        while (0 < text.length()) {
            int len = Math.min(partSize, text.length());
            TextField readOnly = new TextField(NON_FOCUSABLE);
            readOnly.setText(text.substring(0, len));
            add(readOnly);
            add(new NullField());
            text = text.substring(len);
        }
        return text;
    }
}

Multiline LabelField

Multiline text in LabelField, just use newline escape character:

String text = "first line \nnew line \nanother line";
LabelField multiLine = new LabelField(text);
add(multiLine);
