  provide an editor for a datatype. But more complex datatypes might
  provide an expandable item for editing single parts of the

/*!
  \class PropertyList propertyeditor.h
  \brief PropertyList is a TQListView derived class which is used for editing widget properties

  This class is used for widget properties. It has to be child of a
  PropertyEditor.

  To initialize it for editing a widget call setupProperties() which
  iterates through the properties of the current widget (see
  PropertyEditor::widget()) and builds the list.

  To update the item values, refetchData() can be called.

  If the value of an item has been changed by the user, and this
  change should be applied to the widget's property, valueChanged()
  has to be called.

  To set the value of an item, setPropertyValue() has to be called.
