WStandardItemModel::insertColumn states that it"Inserts a single column of|items|at column|column|. If necessary, the row count is increased"
However, the row count is not properly increased. The increase in the row count does not involve a call to beginInsertRows( ) and thus does not properly initialize the header data.
This is realized when the model is cleared or destroyed as 334 headerData.erase(headerData.begin() + index, 335 headerData.begin() + index + count); in WStandardItemModel.C results in segfault ( headerData.size() < count ). This may also affect WStandardItemModel::insertRow Regards, Thomas Suckow
