I suggest that you use a regular expression using the QRegExp class.

let me get this right, you want to restrict the size of your input or you want to check the validity of the input (use QRegExp as said above for validation)
this is what you can do :
QString username=user_name_lineEdit->text(); //get text into the string
int size=username.size();
but is this what you want? I request you to be more clear with your requirements

You can restrain the size with a regexp too... Something like that should be used as a validator: QRegExp(".{1,128}@.{1,128}").

You also can use simpler way: use 3 lineedits(username,domain,pass),with setting needed maxLenght for everyoen.Look in the attachment :)
