Yet another option is to use QTextStream and the  lt  lt  operator in much the same way as you would use cout in C     QPoint point 5 1   QString str  QTextStream  amp str   lt  lt   Mouse click      lt  lt  point x    lt  lt        lt  lt  point y    lt  lt            OUTPUT     Mouse click   5  1     Because operator  lt  lt    has been overloaded  you can use it for multiple types  not just int  QString  arg   is overloaded  for example arg int a1  int a2   but there is no arg int a1  QString a2   so using QTextStream   and operator  lt  lt  is convenient when formatting longer strings with mixed types   Caution  You might be tempted to use the sprintf   facility to mimic C style printf   statements  but it is recommended to use QTextStream or arg   because they support Unicode strings
