Question

Let me give an example. This code works within a manager:

protected boolean navigationMovement(int dx, int dy, int status, int time) {
        int focusIndex = getFieldWithFocusIndex();

        while (dy > 0) {
            if (focusIndex + columnwidth.length >= getFieldCount()) {
                return false;
            } else {
                Field f = getField(focusIndex + columnwidth.length);
                if (f.isFocusable()) {
                    f.setFocus();
                    dy--;
                }
            }
        }

        while (dy < 0) {
            if (focusIndex - columnwidth.length < 0) {
                return false;
            } else {
                Field f = getField(focusIndex - columnwidth.length);
                if (f.isFocusable()) {
                    f.setFocus();
                    dy++;
                }
            }
        }

        while (dx > 0) {
            focusIndex++;
            if (focusIndex >= getFieldCount()) {
                return false;
            } else {
                Field f = getField(focusIndex);
                if (f.isFocusable()) {
                    f.setFocus();
                    dx--;
                }
            }
        }

        while (dx < 0) {
            focusIndex--;
            if (focusIndex < 0) {
                return false;
            } else {
                Field f = getField(focusIndex);
                if (f.isFocusable()) {
                    f.setFocus();
                    dx++;
                }
            }
        }
        return true;
}

Now my screen adds the 3 different managers like this.

add(new Custom_TopField(this, 0, -1, "", 1, 1));
add(new Custom_BottomField(this, 0));
add(new Custom_HeaderField(Config_GlobalFunction.latest));

all also extends Manager but when i go down, it is going left instead of going to the bottom.

I found a solution but this solution is not practical at all. I created all the class within a java class. So, the class cannot be reuse.
