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.
Reimplemented from QgsDataItem.
Definition at line 831 of file qgsdataitem.h.
|
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.
