void Kate::TextHistory::transformCursor	(	int &	line,
		int &	column,
		KTextEditor::MovingCursor::InsertBehavior	insertBehavior,
		qint64	fromRevision,
		qint64	toRevision = -1
	)

Transform a cursor from one revision to an other.

Parameters

line	line number of the cursor to transform
column	column number of the cursor to transform
insertBehavior	behavior of this cursor on insert of text at its position
fromRevision	from this revision we want to transform
toRevision	to this revision we want to transform, default of -1 is current revision

-1 special meaning for from/toRevision

shortcut, same revision

some invariants must hold

transform cursor

forward or reverse transform?

		KTextEditor::MovingRange::EmptyBehavior	emptyBehavior,
		qint64	fromRevision,
		qint64	toRevision = -1
	)

Transform a range from one revision to an other.

Parameters

range	range to transform
insertBehaviors	behavior of this range on insert of text at its position
emptyBehavior	behavior on becoming empty
