Class: QgsDatabaseSchemaComboBox

class qgis.gui.QgsDatabaseSchemaComboBox

Bases: PyQt5.QtWidgets.QWidget

The QgsDatabaseSchemaComboBox class is a combo box which displays the list of schemas for a specific database connection.

Warning

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

New in version 3.14.

QgsDatabaseSchemaComboBox(provider: str, connection: str, parent: QWidget = None) Constructor for QgsDatabaseSchemaComboBox, for the specified provider and connection.

Warning

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

QgsDatabaseSchemaComboBox(connection: QgsAbstractDatabaseProviderConnection, parent: QWidget = None) Constructor for QgsDatabaseSchemaComboBox, for the specified connection.

Ownership of connection is transferred to the combobox.

pyqtSignal(*types, name: str = …, revision: int = …, arguments: Sequence = …) -> PYQT_SIGNAL

types is normally a sequence of individual types. Each type is either a type object or a string that is the name of a C++ type. Alternatively each type could itself be a sequence of types each describing a different overloaded signal. name is the optional C++ name of the signal. If it is not specified then the name of the class attribute that is bound to the signal is used. revision is the optional revision of the signal that is exported to QML. If it is not specified then 0 is used. arguments is the optional sequence of the names of the signal’s arguments.

Parameters
  • name (str = ...) –

  • revision (int = ...) –

  • arguments (Sequence = ...) –

Return type

PYQT_SIGNAL

sender(self) QObject
senderSignalIndex(self) int
setAllowEmptySchema(self, allowEmpty: bool)

Sets whether an optional empty schema (“not set”) option is present in the combobox.

Parameters

allowEmpty (bool) –

setConnectionName(self, connection: str, provider: str = '')

Sets the database connection name from which to retrieve the available schemas.

Optionally the provider can be reset too.

Parameters
  • connection (str) –

  • provider (str = '') –

setSchema(self, schema: str)

Sets the current schema selected in the combo box.

Parameters

schema (str) –
