If you want user to have empty field when they start editing

First use placeHolderText property of QLineEdit to set the default value to display.

Then connect editingFinished (or possibly some other, check them out) signal to your own slot, where you check if text is empty (and then use the placeHolderText value) or if user entered something.

If you want to leave default text for user to edit

Instead of using placeHolderText, simply set contents of the QLineEdit to desired default value, when you create it. Then in the slot for editingFinished, if user made field empty, restore the text to default.

You can do this for example by connecting 

 void QLineEdit::editingFinished () [signal]

and check in the slot actual text from QLineEdit and if necessary set yours.
