[virtual protected] int QTableView::sizeHintForColumn(int column) const

Reimplemented from QAbstractItemView::sizeHintForColumn().

Returns the size hint for the given column's width or -1 if there is no model.

If you need to set the width of a given column to a fixed value, call QHeaderView::resizeSection() on the table's horizontal header.

If you reimplement this function in a subclass, note that the value you return will be used when resizeColumnToContents() or QHeaderView::resizeSections() is called. If a larger column width is required by either the horizontal header or the item delegate, the larger width will be used instead.

See also QWidget::sizeHint and horizontalHeader().

Reimplemented from QAbstractItemView::sizeHintForRow().

Returns the size hint for the given row's height or -1 if there is no model.

If you need to set the height of a given row to a fixed value, call QHeaderView::resizeSection() on the table's vertical header.

If you reimplement this function in a subclass, note that the value you return is only used when resizeRowToContents() is called. In that case, if a larger row height is required by either the vertical header or the item delegate, that width will be used instead.

See also QWidget::sizeHint and verticalHeader().

void QTableView::sortByColumn(int column, Qt::SortOrder order)

[virtual protected] int QTableView::verticalOffset() const

Reimplemented from QAbstractItemView::verticalOffset().

Returns the vertical offset of the items in the table view.

Note that the table view uses the vertical header section positions to determine the positions of rows in the view.
