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.
