QAbstractItemDelegateをサブクラス化しています。これは私のコードです。提案は大歓迎です:
QWidget *ParmDelegate::createWidget(Parm *p, const QModelIndex &index) const {
QWidget *w;
if (index.column() == 0) {
w = new QLabel(p->getName().c_str());
} else {
if (p->isSection())
return NULL;
w = p->createControl();
}
return w;
}
QWidget *ParmDelegate::createEditor(QWidget *parent, const QStyleOptionViewItem &option, const QModelIndex &index) const {
cout << "createEditor called" << endl;
Parm *p = reinterpret_cast<Parm*>(index.internalPointer());
QWidget *retval = createWidget(p, index);
retval->setFocusPolicy(Qt::StrongFocus);
retval->setParent(parent);
return retval;
}
void ParmDelegate::updateEditorGeometry(QWidget *editor, const QStyleOptionViewItem &option, const QModelIndex &index) const {
QRect rect(option.rect);
editor->setGeometry(QRect(QPoint(0,0), rect.size()));
}
void ParmDelegate::paint(QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index) const {
Parm *p = reinterpret_cast<Parm*>(index.internalPointer());
scoped_ptr<QWidget> w(createWidget(p, index));
if (!w)
return;
QRect rect(option.rect);
w->setGeometry(QRect(QPoint(0,0), rect.size()));
w->render(painter, rect.topLeft());
}
QSize ParmDelegate::sizeHint(const QStyleOptionViewItem &option, const QModelIndex &index) const {
Parm *p = reinterpret_cast<Parm*>(index.internalPointer());
scoped_ptr<QWidget> w(createWidget(p, index));
if (!w)
return QSize(0,0);
return w->sizeHint();
}
bool ParmDelegate::editorEvent(QEvent * event, QAbstractItemModel * model, const QStyleOptionViewItem & option, const QModelIndex & index ) {
cout << "editorEvent called" << endl;
return false;
}
これを実行すると、editorEventが編集イベントごとに2回呼び出されるだけです。createEditorはありません。
