I have a question about how the column widths of a QTableView are calculated? How can I have the QTableView set the column with “to contents” that includes the QHeader also? For example I have a QHeaderView with the first “section” that has text “This is a really really really long header”, but the actual data that is in the QTableView under that header are short values such as “100” or “2” or “1.231”. When the QTableView is rendered the the column with is only as wide as the QTableView. It is like the QHeaderView is not taken into account when calculating the width of the column.

This is with Qt 6.5.3 and 6.6.3.

Hi Mike,

you should be able to reimplement https://doc.qt.io/qt-6/qtableview.html#sizeHintForColumn and https://doc.qt.io/qt-6/qtableview.html#sizeHintForRow to take the https://doc.qt.io/qt-6/qheaderview.html#sectionSizeHint into account.

Cheers,
Volker
