Class: QgsDatabaseTableComboBox¶
- class qgis.gui.QgsDatabaseTableComboBox¶
Bases:
PyQt5.QtWidgets.QWidget
The
QgsDatabaseTableComboBox
class is a combo box which displays the list of tables 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.

.The optional
schema
argument can be used to restrict the listed tables to a specific schema.Warning

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
