Disable keyboard input for spinbox entry

[babygal]

QSpinBox *spinBox ;
 spinBox = new QSpinBox;

QSpinBox *spinBox ;
 spinBox = new QSpinBox;

To copy to clipboard, switch view to plain text mode 

There is no setValidator for QSpinBox like as for QLineEdit.
I want to restrict the user's input to clicking up and down arrows only,
and not allow user to type a value into the spin box's line editor.
How to do ?
