Hi
I am trying to hook up a spin box to create rows in a table and automatically populate them with comboboxes .. I have manged to use the signal/slot mechanism to create the extra rows of the table (from the sigbnal of the spinbox) and the first row has the correct comboboxes (created on startup)- but I cannot figure out how to create and populate the new rows with new combo boxes.
The following is the code ...

I am also running this to start the gui..
Qt Code: 
  1. #!/usr/bin/python -d
  2.  
  3. import sys
  4. from PyQt4 import QtCore, QtGui
  5. from table8 import Ui_Form 
  6.  
  7. # Lars set this path to where you have my scripts!
  8. sys.path += ['/jobs/generic/shots/lightDome/qtDesigner']
  9.  
  10. class MyForm(QtGui.QMainWindow):
  11. 	def __init__(self, parent=None):
  12. 		QtGui.QWidget.__init__(self, parent)
  13. 		self.ui = Ui_Form()
  14. 		self.ui.setupUi(self)
  15. 		#QtCore.QObject.connect(self.ui.pushButton, QtCore.SIGNAL("clicked()"), self.ui.textEdit.clear )
  16. 		#QtCore.QObject.connect(self.ui.lineEdit, QtCore.SIGNAL("returnPressed()"), self.add_entry)
  17.  
  18. if __name__ == "__main__":
  19. 	app = QtGui.QApplication(sys.argv)
  20. 	myapp = MyForm()
  21. 	myapp.show()
  22. 	sys.exit(app.exec_())

I guess
self.comboBoxNew = QtGui.QComboBox(Form)
in createMyRow(self, rows):
doesn't know about Form but I don' know how to get around this
Thanks in advance
