[PySide] Passing parameter from one class to an external function

[Frank Rueter | OHUfx]

just indent your "greetings" function so it becomes a method to the 
"Form" class, then it will work.

import sys
from PySide.QtCore import *
from PySide.QtGui import *


class Form(QDialog):

     def __init__(self, parent=None):

         QDialog.__init__(self, parent=None)

         self.edit = QLineEdit("Write my name here")
         self.button = QPushButton("Show Greetings")
         self.layout = QVBoxLayout()
         self.layout.addWidget(self.edit)
         self.layout.addWidget(self.button)
         self.setLayout(self.layout)
         self.button.clicked.connect(self.greetings)


     def greetings(self):
         print ("Hello %s" % self.edit.text())


if __name__ == '__main__':
     app = QApplication(sys.argv)
     form = Form()
     form.show()
     sys.exit( app.exec_() )
