          sorry for the late reply. I am attaching the code. as the code is having more .cpp and .h files, i am attaching only the page for which the clarification is needed. once again i will tell the aim of the program is listed below:
          (1) i want to access the serially transmitted datas from another computer
          (2) As soon as the datas are received the same should be displyed in a oscilloscope.

          Problem to be solved:
          (1) I am able to display one window and able to collect the data through serial port. I have placed a push button in that window. wen the push button is clicked i want to generate a new window in which the qwt oscilloscope window has to be displayed.
          (2) I will show the line of code which i have written in this program for the same

          connect(ui->openCloseButton, SIGNAL(clicked()), SLOT(osci()));

          after the same i have called the osci() function as the one below.
          void MainWindow::osci()
          {
          QMainWindow *osci = new QMainWindow(this);
          osci->show(); }

          Now wen i am clicking a new window is displaying . My question is how to add the components into that new window. or how to include the oscilloscope program of qwt to it .
          I was not able to post the entire code here as it is showing exceeding of 6000 characters
          I will really gratefull if anybody can give the solution for the one above.
          I am conveying my advance thanks to all.

          expecting a postive reply

            Hi Sanoop,
            Instead of a regular QMainWindow, create your own window subclassed from a QMainWindow.

            Example
            @
            class osciWindow : public QMainWindow
            {
            Q_OBJECT
            ..... // define your elements
            QPushButton *button1;
            QPushButton *button2;
            }
            @

            In your slot, display the above window.....
            @
            MainWindow::osci()
            {
            osciWindow *osci = new osciWindow(this);
            osci->show();
            }
            @

            Follow the Qt examples, they are very good.
