Class: QgsLayerMetadataResultsModel

class qgis.gui.QgsLayerMetadataResultsModel

Bases: PyQt5.QtCore.QAbstractTableModel

The QgsLayerMetadataResultsModel class handles the metadata fetching from the registered layer metadata providers.

New in version 3.28.

QgsLayerMetadataResultsModel(searchContext: QgsMetadataSearchContext, parent: QObject = None) Constructs a QgsLayerMetadataResultsModel from a searchContext and an optional parent.

progressChanged

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

receivers(self, PYQT_SIGNAL) → int

reload(self)

Load/Reload model data synchronously.

reloadAsync(self)

Load/Reload model data asynchronously using threads.

resetInternalData(self)

resultsReady(self, results: QgsLayerMetadataSearchResults)

Triggered when metadata results have been fetched and can be added to the model.

Parameters:

results (QgsLayerMetadataSearchResults) –

rowCount(self, parent: QModelIndex) → int

Parameters:

parent (QModelIndex) –

Return type:

int

sender(self) → QObject

senderSignalIndex(self) → int
