[PyQt] QPrintDialog (pyqt4)

[Russell Valentine]

You can do something like this if it is a function of your MainWindow. 
self as a argument in grabWidget is your baseWidget, like a QMainWindow 
for example. No doubt you would have to make sure it fits on the page 
though and resize it as needed.

    def goPrinter(self):
         printer=QtGui.QPrinter()
         dialog = QtGui.QPrintDialog(printer, self)
         if(dialog.exec_() != QtGui.QDialog.Accepted):
             return
         p=QtGui.QPixmap.grabWidget(self)
         printLabel = QtGui.QLabel()
         printLabel.setPixmap(p)
         painter = QtGui.QPainter(printer)
         printLabel.render(painter)
         painter.end()
