def createEditor(self, parent, option, index):
"""
Create for the display and interaction with the user an editor.
@param QtGui.QWidget parent: The parent object (probably QTableView)
@param QtGui.QStyleOptionViewItemV4 option: This is a setting option which you can use for
style configuration.
@param QtCore.QModelIndex index: That index will be passed by the model object of the
QTableView to the delegated object. This index contains
information about the selected current cell.
An editor can be in principle any QWidget, which you want to use to display the current
(model-)data. Therefore the editor is like a container, which handles the passed entries
from the user interface and should save the data to the model object of the QTableWidget.
The setEditorData function reads data from the model.
Do not save the created editor as a class variable! This consumes a lot of unneeded memory.
It is way better to create an editor if it is needed. The inherent function closeEditor()
of QStyledItemDelegate takes care of closing and destroying the editor for you, if it is not
needed any longer.
