<![CDATA[Whether Dialog window's object's memory is leaking or not ?]]>void MainWindow::on_pushButton_clicked() { toDoList = new Dialog(this); toDoList->exec(); int code = toDoList->result(); // print dialog code returned switch(code){ case 0: qDebug()<< "Rejected Dialog code is returned "<<Qt::endl; break; case 1: qDebug()<< "Accepted Dialog code is returned "<< Qt::endl; break; default: qDebug()<< "Nothing is return form Dialog Window"<< Qt::endl; } }

Your not deleting it at all so yes the memory use will increase until MainWindow is deleted.

Create your dialog on the stack, the way you use it does not justify to use the heap.
