Hi Santosh,

First of all, thanks for replying.
I have already checked it...
1. Slot is called and
2. A new QMainWindow is created below the QDialog.
But my problem is i want to put this new QMainWindow above the QDialog,(not hidden below the QDialog) when it is created.
so can you help me.

I guess you are creating a modal dialog, try this

void MyDialog:penMyForm() 
{ 
    setModal(false);
    myForm = new QMainWindow; 
    myForm->show(); 
}

void MyDialog:penMyForm() 
{ 
    setModal(false);
    myForm = new QMainWindow; 
    myForm->show(); 
}

To copy to clipboard, switch view to plain text mode 

Update: You can also make dialog as parent of QMainWindow, this way mainwindow till remain on top of dialog

void MyDialog:penMyForm() 
{ 
    setModal(false);
    myForm = new QMainWindow(this); 
    myForm->show(); 
}

void MyDialog:penMyForm() 
{ 
    setModal(false);
    myForm = new QMainWindow(this); 
    myForm->show(); 
}

To copy to clipboard, switch view to plain text mode

Do you show the dialog by calling QDialog::exec()? Use QDialog::show() instead of calling QDialog::exec(). If you want the main window always on top, you can set it as modal (setWindowModality(Qt::WindowModality);
