Detailed Description

A model containing tables from a database connection.

This class does not automatically subscribe to database updates. Tables are queried from the database initially upon model construction. In order to update the listed tbales, QgsDatabaseTableModel::refresh() must be manually called.

Role

enum QgsDatabaseTableModel::Role

Model roles.

Enumerator

Constructor & Destructor Documentation

QgsDatabaseTableModel() [1/2]

QgsDatabaseTableModel::QgsDatabaseTableModel ( const QString &  provider, const QString &  connection, const QString &  schema = QString(), QObject *  parent = nullptr  )

explicit

Constructor for QgsDatabaseTableModel, for the specified provider and connection name.

The optional schema argument can be used to restrict the tables to those from a specific schema.

Warning

The provider must support the connection API methods in its QgsProviderMetadata implementation in order for the model to work correctly.

Definition at line 21 of file qgsdatabasetablemodel.cpp.

QgsDatabaseTableModel() [2/2]

QgsDatabaseTableModel::QgsDatabaseTableModel ( QgsAbstractDatabaseProviderConnection *  connection, const QString &  schema = QString(), QObject *  parent = nullptr  )

explicit

Constructor for QgsDatabaseTableModel, for the specified connection.

The optional schema argument can be used to restrict the tables to those from a specific schema.

Ownership of connection is transferred to the model.
