I would like to modify the appearance and behavior of the widget in the upper left hand corner of a table. However, the only reference I can find to this widget is to enable / disable it via "QTableView::setCornerButtonEnabled()" and its related methods.

Poking around in the Qt source code I did find a reference "QTableViewPrivate::cornerWidget" but I don't know how to access this data member and am hesitant to try.

I would appreciate some advice from someone who has more experience with Qt Tables.

Respectfully,
