Detailed description

[const] bool canFetchMore(const QModelIndex parent = QModelIndex())

Description: Method bool QSqlQueryModel::canFetchMore(const QModelIndex &parent)

This is a reimplementation of QAbstractItemModel::canFetchMore

void clear

Description: Method void QSqlQueryModel::clear()

[const] int columnCount(const QModelIndex parent = QModelIndex())

Description: Method int QSqlQueryModel::columnCount(const QModelIndex &parent)

This is a reimplementation of QAbstractItemModel::columnCount

void create

Description: Ensures the C++ object is created

Use this method to ensure the C++ object is created, for example to ensure that resources are allocated. Usually C++ objects are created on demand and not necessarily when the script object is created.

[const] QVariant data(const QModelIndex item,int role = Qt::DisplayRole)

Description: Method QVariant QSqlQueryModel::data(const QModelIndex &item, int role)

This is a reimplementation of QAbstractItemModel::data

void destroy

Description: Explicitly destroy the object

Explicitly destroy the object on C++ side if it was owned by the Ruby interpreter. Subsequent access to this object will throw an exception. If the object is not owned by Ruby, this method will do nothing.

[const] bool destroyed?

Description: Returns a value indicating whether the object was already destroyed

This method returns true, if the object was destroyed, either explicitly or by the C++ side. The latter may happen, if the object is owned by a C++ object which got destroyed itself.

void fetchMore(const QModelIndex parent = QModelIndex())

Description: Method void QSqlQueryModel::fetchMore(const QModelIndex &parent)

This is a reimplementation of QAbstractItemModel::fetchMore

[const] QVariant headerData(int section,const Qt_Orientation orientation,int role = Qt::DisplayRole)

Description: Method QVariant QSqlQueryModel::headerData(int section, Qt::Orientation orientation, int role)

This is a reimplementation of QAbstractItemModel::headerData

bool insertColumns(int column,int count,const QModelIndex parent = QModelIndex())

Description: Method bool QSqlQueryModel::insertColumns(int column, int count, const QModelIndex &parent)

This is a reimplementation of QAbstractItemModel::insertColumns

[const] bool is_const_object?

Description: Returns a value indicating whether the reference is a const reference

This method returns true, if self is a const reference. In that case, only const methods may be called on self.

[const] QSqlError lastError

Description: Method QSqlError QSqlQueryModel::lastError()

[static] new QSqlQueryModel new(QObject ptr parent = 0)

Description: Constructor QSqlQueryModel::QSqlQueryModel(QObject *parent)

This method creates an object of class QSqlQueryModel.

[const] QSqlQuery query

Description: Method QSqlQuery QSqlQueryModel::query()

void query=(const QSqlQuery query)

Description: Method void QSqlQueryModel::setQuery(const QSqlQuery &query)

[const] QSqlRecord record(int row)

Description: Method QSqlRecord QSqlQueryModel::record(int row)

[const] QSqlRecord record

Description: Method QSqlRecord QSqlQueryModel::record()

bool removeColumns(int column,int count,const QModelIndex parent = QModelIndex())

Description: Method bool QSqlQueryModel::removeColumns(int column, int count, const QModelIndex &parent)

This is a reimplementation of QAbstractItemModel::removeColumns

[const] int rowCount(const QModelIndex parent = QModelIndex())

Description: Method int QSqlQueryModel::rowCount(const QModelIndex &parent)

This is a reimplementation of QAbstractItemModel::rowCount

bool setHeaderData(int section,const Qt_Orientation orientation,const QVariant value,int role = Qt::EditRole)

Description: Method bool QSqlQueryModel::setHeaderData(int section, Qt::Orientation orientation, const QVariant &value, int role)

This is a reimplementation of QAbstractItemModel::setHeaderData

void setQuery(const QSqlQuery query)

Description: Method void QSqlQueryModel::setQuery(const QSqlQuery &query)

void setQuery(string query,const QSqlDatabase db = QSqlDatabase())

Description: Method void QSqlQueryModel::setQuery(const QString &query, const QSqlDatabase &db)

[static] QMetaObject staticMetaObject

Description: Obtains the static MetaObject for this class.

[static] string tr(string s,string c = 0)

Description: Static method QString QSqlQueryModel::tr(const char *s, const char *c)

This method is static and can be called without an instance.

[static] string tr(string s,string c,int n)

Description: Static method QString QSqlQueryModel::tr(const char *s, const char *c, int n)

This method is static and can be called without an instance.

[static] string trUtf8(string s,string c = 0)

Description: Static method QString QSqlQueryModel::trUtf8(const char *s, const char *c)

This method is static and can be called without an instance.

[static] string trUtf8(string s,string c,int n)

Description: Static method QString QSqlQueryModel::trUtf8(const char *s, const char *c, int n)

This method is static and can be called without an instance.
