Constructor & Destructor Documentation
◆ QgsProjectItem()
| QgsProjectItem::QgsProjectItem | ( | QgsDataItem * | parent, |
| const QString & | name, | ||
| const QString & | path, | ||
| const QString & | providerKey = QString() |
||
| ) |
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. providerKey key of the provider that created this item
Definition at line 21 of file qgsprojectitem.cpp.
Member Function Documentation
◆ hasDragEnabled()
|
inlineoverridevirtual |
Returns true if the item may be dragged.
Default implementation returns false. A draggable item has to implement mimeUris() that will be used to pass data.
- See also
- mimeUris()
- Since
- QGIS 3.0
Reimplemented from QgsDataItem.
Definition at line 50 of file qgsprojectitem.h.
◆ mimeUris()
|
overridevirtual |
Returns mime URIs for the data item, most data providers will only return a single URI but some data collection items (e.g.
GPKG, OGR) may report multiple URIs (e.g. for vector and raster layer types).
Items that return valid URI will be returned in mime data when dragging a selection from browser model.
- Since
- QGIS 3.18
Reimplemented from QgsDataItem.
Definition at line 30 of file qgsprojectitem.cpp.
