Yes, Raj, I use timerStart() method of QLineEdit, but I don't removes
the  character, I just use setCursorPosition(). If I resize the
LineEdit, then the method removing the characters will become tedious.


But there's also a little problem for me. When I open the LineEdit, the
LineEdit will stop for a little time, then it can move. I think it may
wait for the cursor move the the last position of the LineEdit show
currently.
