◆ createEditor()

QWidget * QPPDOptionsEditor::createEditor ( QWidget parent,
const QStyleOptionViewItem option,
const QModelIndex index 
) const
virtual

Returns the editor to be used for editing the data item with the given index.

Note that the index contains information about the model being used. The editor's parent widget is specified by parent, and the item options by option.

The base implementation returns 0. If you want custom editing you will need to reimplement this function.

The returned editor widget should have Qt::StrongFocus; otherwise, QMouseEvent received by the widget will propagate to the view. The view's background will shine through unless the editor paints its own background (e.g., with QWidget::setAutoFillBackground()).
