Member Function Documentation

◆ getModifiedObjects()

void OpenOrienteering::SwitchPartUndoStep::getModifiedObjects	(	int	part_index,
		UndoStep::ObjectSet &	out
	)		const

overridevirtual

Adds the list of the step's modified objects to the container provided by out.

Only adds objects when the given part_index matches this step's part index.

Reimplemented from OpenOrienteering::ObjectModifyingUndoStep.

◆ getModifiedParts()

bool OpenOrienteering::SwitchPartUndoStep::getModifiedParts ( UndoStep::PartSet & out ) const

overridevirtual

Adds the the step's modified part to the container provided by out.

Returns: True if there are objects modified by this undo step, false otherwise.

Reimplemented from OpenOrienteering::ObjectModifyingUndoStep.

◆ loadImpl()

void OpenOrienteering::SwitchPartUndoStep::loadImpl	(	QXmlStreamReader &	xml,
		SymbolDictionary &	symbol_dict
	)

overrideprotectedvirtual

Loads undo properties from the the xml stream.

Implementations in derived classes shall first check the element's name for one of their own elements, and otherwise call the parent class' implementation.

Reimplemented from OpenOrienteering::ObjectModifyingUndoStep.

◆ saveImpl()

void OpenOrienteering::SwitchPartUndoStep::saveImpl ( QXmlStreamWriter & xml ) const

overrideprotectedvirtual

Saves undo properties to the the xml stream.

Implementations in derived classes shall first call the parent class' implementation, and then start a new element for additional properties.

Reimplemented from OpenOrienteering::ObjectModifyingUndoStep.

◆ undo()

UndoStep * OpenOrienteering::SwitchPartUndoStep::undo ( )

overridevirtual

Undoes the action and returns a new UndoStep.

The returned UndoStep can redo the action again.

Implements OpenOrienteering::UndoStep.
