Class Hierarchy

• pyads.gui.ADSMapper: Objects of this class represent a plc process value. The class accomblishes a connection between plc and the gui. For implementing the interaction between gui objects and plc values subclass and implement mapAdsToGui according to the given examples.

  sample code:

  >>> class TextBoxMapper (ADSMapper):
  >>>     def mapAdsToGui(self, guiObject, value):
  >>>         guiObject.setText(str(value))

  >>> class ComboBoxMapper (ADSMapper):
  >>>     def mapAdsToGui(self, guiObject, value):
  >>>         index = guiObject.findData(QVariant(value))
  >>>         guiObject.setCurrentIndex(index)

  >>> class DSpinBoxMapper (ADSMapper):
  >>>     def mapAdsToGui(self, guiObject, value):
  >>>         guiObject.setValue(float(value))

  >>> class SpinBoxMapper (ADSMapper):
  >>>     def mapAdsToGui(self, guiObject, value):
  >>>         guiObject.setValue(int(value))

  >>> class BinaryMapper (ADSMapper):
  >>>     def mapAdsToGui(self, guiObject, value):
  >>>         guiObject.setText(__builtin__.bin(int(value)))
