Make sure you have Field.FOCUSABLE fields outside your HFM's visible area - then it will start scrolling on navigation.  Use NullField(NullField.FOCUSABLE) if you don't want your own fields to receive focus.

Good luck!

hey i agree with arkadyz

in blackberry u can scroll only if u have scrollable fields present

make sure that the region where u want to have horizontal scroll bar must contain focussable fields

infact if u do not have scrollable fields u can add blank,focussable label fields

add(new LabelField("",Field.FOCUSABLE));

[ritupurohit]

ObjectListField listfield=new ObjectListField(ObjectListField.FOCUSABLE);

added elements into vector and displayed o/p as columns using drawlistrow.

public boolean trackwheelRoll(int amount, int status, int time)   
    {
   
     //   listfield.invalidate();
        return navigationMovement(0,amount,status,time);
    }

protected boolean navigationMovement(int dx, int dy, int status, int time) {
if( listfield.getSelectedIndex() + dy >= listfield.getSize() ) {
return true;

}

....is dis code correct??? when i click on alt key in my 8700 simulator it shows me up n down arrow key...i wanna scroll left and right ..
