Base class for history entry "group" nodes, which contain children of their own.
QgsHistoryEntryGroup & operator=(const QgsHistoryEntryGroup &other)=delete
QgsHistoryEntryGroup()=default
QgsHistoryEntryGroup(const QgsHistoryEntryGroup &other)=delete
~QgsHistoryEntryGroup() override
Base class for nodes representing a QgsHistoryEntry.
QgsHistoryEntryNode & operator=(const QgsHistoryEntryNode &other)=delete
virtual ~QgsHistoryEntryNode()
virtual QVariant data(int role=Qt::DisplayRole) const =0
Returns the node's data for the specified model role.
QgsHistoryEntryNode()=default
QgsHistoryEntryNode(const QgsHistoryEntryNode &other)=delete
QgsHistoryEntryGroup * parent()
Returns the node's parent node.
Contains settings which reflect the context in which a history widget is shown, e....
