Delegate not work
-
hi,all
i am a newbie.i used delegate in tabview,but it cannot work properly.
@ view = new QTableView(this);
QStringList list;
list<<tr( "item1" )<<tr( "item2" )<<tr( "item3" )<<tr( "item4" );
viewModel = new QStandardItemModel(0,list.count(),this);
view->setModel( viewModel );
ComboxDelegate comboBoxDelegate1;
view->setItemDelegateForColumn(3, &comboBoxDelegate1);@my delegate:
@class ComboxDelegate : public QItemDelegate
{
Q_OBJECT
public:
ComboxDelegate(QObject *parent = 0): QItemDelegate(parent) { }
QWidget *createEditor(QWidget *parent, const QStyleOptionViewItem &option,
const QModelIndex &index) const
{
QComboBox *editor = new QComboBox(parent);
editor->addItem("Female");
editor->addItem("Male");
return editor;
}
void setEditorData(QWidget *editor, const QModelIndex &index) const
{
QString text = index.model()->data(index, Qt::EditRole).toString();
QComboBox comboBox = static_cast<QComboBox>(editor);
int tindex = comboBox->findText(text);
comboBox->setCurrentIndex(tindex);
}
void setModelData(QWidget *editor, QAbstractItemModel *model,
const QModelIndex &index) const
{
QComboBox comboBox = static_cast<QComboBox>(editor);
QString text = comboBox->currentText();
model->setData(index, text, Qt::EditRole);
}
void updateEditorGeometry(QWidget *editor,
const QStyleOptionViewItem &option, const QModelIndex &index) const
{
editor->setGeometry(option.rect);
}
};@ -
Hi and welcome to devnet,
You need to explain what doesn't work.
From a quick overview:
@
ComboxDelegate comboBoxDelegate1;
view->setItemDelegateForColumn(3, &comboBoxDelegate1);
@comboBoxDelegate1 will be destroyed shortly after that so it won't be used.
