Detailed Description

A Collection that represents a database schema item.

Since: QGIS 3.16

Definition at line 740 of file qgsdataitem.h.

Constructor & Destructor Documentation

◆ QgsDatabaseSchemaItem()

QgsDatabaseSchemaItem::QgsDatabaseSchemaItem	(	QgsDataItem *	parent,
		const QString &	name,
		const QString &	path = `QString()`,
		const QString &	providerKey = `QString()`
	)

Constructor for QgsDatabaseSchemaItem, with the specified parent item.

The name argument specifies the text to show in the model for the item. A translated string should be used wherever appropriate.

The path argument gives the item path in the browser tree. The path string can take any form, but QgsSchemaItem items pointing to different logical locations should always use a different item path.

The optional providerKey string can be used to specify the key for the QgsDataItemProvider that created this item.

Member Function Documentation

◆ databaseConnection()

QgsAbstractDatabaseProviderConnection * QgsDatabaseSchemaItem::databaseConnection ( ) const

overridevirtual

For data items that represent a DB connection or one of its children, this method returns a connection.

All other data items will return NULL.

Ownership of the returned objects is transferred to the caller.

Since: QGIS 3.16

Reimplemented from QgsDataCollectionItem.
