Class: QgsDataCollectionItem¶

class qgis.core.QgsDataCollectionItem(parent: QgsDataItem, name: str, path: str = '', providerKey: str = '')¶

Bases: QgsDataItem

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.

A Collection: logical collection of layers or subcollections, e.g. GRASS location/mapset, database? wms source?

addChild(self, item: QgsDataItem)¶

Parameters: item (QgsDataItem) –

childEvent(self, QChildEvent)¶

connectNotify(self, QMetaMethod)¶

customEvent(self, QEvent)¶

deferredDelete(self) → bool¶: The item is scheduled to be deleted. E.g. if deleteLater() is called when item is in Populating state (createChildren() running in another thread), the deferredDelete() returns True and item will be deleted once Populating finished. Items with slow reateChildren() (for example network or database based) may check during createChildren() if deferredDelete() returns True and return from createChildren() immediately because result will be useless. *

disconnectNotify(self, QMetaMethod)¶

homeDirIcon() → QIcon¶

Shared home directory icon.

New in version 3.4.

Return type: QIcon

iconDataCollection() → QIcon¶

Returns the standard browser data collection icon.
