◆ dirPath()

QString QgsDirectoryItem::dirPath ( ) const

inline

Returns the full path to the directory the item represents.

Definition at line 633 of file qgsdataitem.h.

◆ equal()

bool QgsDirectoryItem::equal ( const QgsDataItem * other )

overridevirtual

Returns true if this item is equal to another item (by testing item type and path).

Reimplemented from QgsDataItem.
