Public Member Functions
	SelectionChange (TextEditorController *controller)
	The selection selection change constructor.
virtual	~SelectionChange ()
	destructs the textrange
virtual void	giveTextRangeSet (TextRangeSet *rangeSet)
	Gives the textrange to the textchange.
virtual TextRangeSet *	takeRangeSet ()
	Takes ownership of the rangeset and clears the clearset.
virtual void	execute (TextDocument *document)
	Executes the textchange.
virtual void	revert (TextDocument *document)
	Reverts the selection change.
virtual bool	giveAndMerge (TextDocument *document, Change *textChange)
	This method tries to merge the given change with the other change The textChange supplied with this method. Should NOT have been executed yet. It's the choice of this merge operation if the execution is required.
TextRangeSet *	rangeSet ()
virtual QString	toString ()
	Convert this change to a string.
Public Member Functions inherited from edbee::ControllerChange
	ControllerChange (TextEditorController *controller)
	A controller specific textcommand. Warning you should NOT modify the textdocument!
virtual TextEditorController *	controllerContext ()
	A text command can belong to a controller/view When it's a view only command. The undo only applies only to this view.
virtual TextEditorController *	controller ()
	returns the controller
Public Member Functions inherited from edbee::Change
virtual	~Change ()
	a virtual empty destructor
virtual bool	canUndo ()
	This method should return true if the change can be reverted.
virtual bool	isPersistenceRequired ()
	This flag is used to mark this stack item as non-persistence requirable The default behaviour is that every textchange requires persistence. It is also possible to have certain changes that do not require persitence but should be placed on the undo stack.
bool	isDocumentChange ()
	this method can be used to check if the given change is a document change
virtual bool	isGroup ()
	This method returns true if this change is a group change. When an object is group change it should be inherited by TextChangeGroup.

Protected Member Functions
void	notifyChange ()
	This method is called internally for notifying the control the selection has been changed Perhaps we should make e proper emit-signal for this purpose.
