Detailed Description

Map undo step which changes the symbols of referenced objects.

Constructor & Destructor Documentation

◆ SwitchSymbolUndoStep()

OpenOrienteering::SwitchSymbolUndoStep::SwitchSymbolUndoStep ( Map * map )

◆ ~SwitchSymbolUndoStep()

OpenOrienteering::SwitchSymbolUndoStep::~SwitchSymbolUndoStep ( )

override

Member Function Documentation

◆ addObject()

void OpenOrienteering::SwitchSymbolUndoStep::addObject	(	int	index,
		const Symbol *	target_symbol
	)

virtual

◆ isValid()

bool OpenOrienteering::SwitchSymbolUndoStep::isValid ( ) const

overridevirtual

Returns true if the step can still be undone.

Initially (after generating the step) this must return true. (However, this is different for InvalidUndoStep.)

Derived classes may return false to indicate that the step is no longer valid. This may happen after an object the step depends on, which is not tracked by the undo system, is deleted.

Example: changing a map object's symbol to a different one, then deleting the first symbol. Then changing the symbol cannot be undone as the old symbol does not exist anymore.

Reimplemented from OpenOrienteering::UndoStep.

◆ loadImpl()

void OpenOrienteering::SwitchSymbolUndoStep::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::SwitchSymbolUndoStep::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.

◆ symbolChanged

		const OpenOrienteering::Symbol *	old_symbol

◆ undo()

UndoStep * OpenOrienteering::SwitchSymbolUndoStep::undo ( )

overridevirtual

Undoes the action and returns a new UndoStep.

The returned UndoStep can redo the action again.

Implements OpenOrienteering::UndoStep.
