Detailed Description

The QgsHistoryProviderRegistry is a registry for objects which track user history (i.e.

operations performed through the GUI).

QgsHistoryProviderRegistry is not usually directly created, but rather accessed through QgsGui::historyProviderRegistry().

Since: QGIS 3.24

◆ historyCleared

void QgsHistoryProviderRegistry::historyCleared	(	Qgis::HistoryProviderBackend	backend,
		const QString &	providerId
	)

signal

QList< QgsHistoryEntry > QgsHistoryProviderRegistry::queryEntries	(	const QDateTime &	start = `QDateTime()`,
		const QDateTime &	end = `QDateTime()`,
		const QString &	providerId = `QString()`,
		Qgis::HistoryProviderBackends	backends = `Qgis::HistoryProviderBackend::LocalProfile`
	)		const

Queries history entries which occurred between the specified start and end times.

The optional providerId and backends arguments can be used to filter entries.

Definition at line 215 of file qgshistoryproviderregistry.cpp.

◆ removeProvider()

bool QgsHistoryProviderRegistry::removeProvider ( const QString & id )
