Thanks
Bala

try this:
QPushButton("123\n456")

it works
i coded manually. but is there anyother ways to do it automatically?

Code:

---

int wrapLen=30;
if(strCaption.length()>wrapLen)
        {
            strCaption=strCaption.left(wrapLen)+"\n"+strCaption.mid(wrapLen,strCaption.length()-wrapLen+1);
        }
