Definition at line 662 of file qgsdataitem.h.

Constructor & Destructor Documentation

◆ QgsProjectItem()

QgsProjectItem::QgsProjectItem	(	QgsDataItem *	parent,
		const QString &	name,
		const QString &	path
	)

A data item holding a reference to a QGIS project file.

Parameters

parent	The parent data item.
name	The name of the of the project. Displayed to the user.
path	The full path to the project.

Definition at line 1210 of file qgsdataitem.cpp.

Member Function Documentation

◆ hasDragEnabled()

bool QgsProjectItem::hasDragEnabled ( ) const

inlineoverridevirtual

Returns true if the item may be dragged.

Default implementation returns false. A draggable item has to implement mimeUri() that will be used to pass data.

See also: mimeUri()

Since: QGIS 3.0

Reimplemented from QgsDataItem.

Definition at line 675 of file qgsdataitem.h.

◆ mimeUri()

QgsMimeDataUtils::Uri QgsProjectItem::mimeUri ( ) const

overridevirtual

Returns mime URI for the data item.

Items that return valid URI will be returned in mime data when dragging a selection from browser model.

See also: hasDragEnabled()

Since: QGIS 3.0

Reimplemented from QgsDataItem.

Definition at line 1218 of file qgsdataitem.cpp.
