const QString & | name, | ||
const QString & | path = QString() , |

const QString & | providerKey = QString() |

) |
Constructor for QgsDataCollectionItem, 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 QgsDataCollectionItem 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.
