Represents a begin or end of a folding region.
FoldingRegion()
Constructs an invalid folding region, meaning that isValid() returns false.
Type
Defines whether a FoldingRegion starts or ends a folding region.
@ Begin
Indicates the start of a FoldingRegion.
@ None
Used internally as indicator for an invalid FoldingRegion.
@ End
Indicates the end of a FoldingRegion.
int id() const
Returns a unique identifier for this folding region.
bool isValid() const
Returns true if this is a valid folding region.
Type type() const
Returns whether this is the begin or end of a region.
FoldingRegion sibling() const
Returns the matching start or end region.
bool operator==(const FoldingRegion &other) const
Compares two FoldingRegion instances for equality.
Type type(const QSqlDatabase &db)
Syntax highlighting engine for Kate syntax definitions.
