These actions relate to editing the cell contents. Suggest you read the Assistant page on QAbstractItemDelegate, with its examples. The Item Delegate is what gets invoked when Qt thinks the user wants to modify the contents of a cell. Here are the notes I wrote to myself after figuring out how to create an Abstract Item Delegate: # a custom delegate is: an object that represents a # type of data when an instance of that type needs to be displayed or edited. # The delegate must implement 3 methods: # createEditor() returns a widget that the table view will position over the # table cell to act as an editor, e.g. a combo-box or line-edit; # setEditorData() initializes the editor widget with data to display; # setModelData() is called when editing is complete, to store possibly # changed data back to the model. This is how you get control whenever the user indicates BY ANY MEANS that she is ready to input or modify data, or has finished modifying the data.
