I'm using this in Model/View classes for a while without any issue. But... I always wondered why it is necessary to have both signals (one before and one after) in the underlying mechanism, and what could be wrong in doing:
-modify the model underlying data structure by inserting rows- beginInsertRows() endInsertRows() Instead of the regular: beginInsertRows() -modify the model underlying data structure by inserting rows- endInsertRows() It's always better to understand why are things done how they are... Thanks! Etienne
