Giuseppe D'Angelo a0bcad3903 QAbstractProxyModel: delay headerDataChanged emissions when inserting/removing rows/columns ... 33c88f86b5 added some logic to QAPM in order to have it automatically emit headerDataChanged when rows/columns were added or removed in the model. This was done as a stopgap measure to prevent QAPM from asking for illegal indices in order to implement automatic remapping of the section headings (since there's no mapSectionToSource). The commit seems to have introduced a regression in QHeaderView, which isn't prepared to receive headerDataChanged while a row/column count change is in progress. When receiving headerDataChanged, QHeaderView will try to read the row/column count and will store it internally. When it will then receive the signals for insertion/removal of rows/columns, it will interpret it as a modification of the previously stored value -- even if the value it stored was already correct. Fix this by avoiding to have two signals in flight at the same time; emit headerDataChanged as a queued invocation.
