示例1: setEditorData

const QModelIndex &index) const
{
const QVariant value = index.data(Qt::EditRole);
if (value.type() == QVariant::StringList) {

else

const int extraWidth = 25;
const int extraHeight = 6;

// to prevent possible hiding bottom part of the list
const int h = lw->count() * (lw->visualItemRect(lw->currentItem()).height() + extraHeight);

// now lw can be partially hidden behind the tree view
// if tree view has small rect, so set parent of lw
// to app window and map coordinates accordingly to leave lw in place
