Public Member Functions
	TextRegion (const Type &type=Type::type_unknown)
	Initializes a new instance of the TextRegion class. This class represents Text regions (Region::type_text_region). More...

void	setText (const QString &text)
	Set the GT/HTR text of the TextRegion. More...

QString	text () const
	GT/HTR Text of the TextRegion. More...

virtual bool	read (QXmlStreamReader &reader) override
	Reads a TextRegion from the XML stream. The stream must be at the position of the TextRegion's tag and is forwarded until its end More...

virtual void	write (QXmlStreamWriter &writer) const override
	Writes the TextRegion instance to the XML stream. More...

virtual QString	toString (bool withChildren=false) const override
	Returns a string with all important properties of the TextRegion. More...

virtual void	draw (QPainter &p, const RegionTypeConfig &config) const override
	Draws the TextRegion to the Painter. More...

Public Member Functions inherited from rdf::Region
	Region (const Type &type=Type::type_unknown, const QString &id="")
	Initializes a new instance of the Region class. The Region is the base class for all Region elements that are contained in the extended PAGE XML. More...

bool	isEmpty () const

void	setSelected (bool select)

bool	selected () const

void	setType (const Region::Type &type)
	Sets the Region type. More...

Region::Type	type () const
	The Region's type (e.g. type_text_region). More...

void	setId (const QString &id)
	Set a unique identifier to the region. More...

QString	id () const
	Returns the Region's unique identifier. More...

void	setCustom (const QString &c)

QString	custom () const

void	setPolygon (const Polygon &polygon)
	Set the polygon which enclosed the Region. The polygon's coordinates are w.r.t the image coordinates. More...

Polygon	polygon () const
	The Region's polygon. More...

void	scaleRegion (double scale)

void	addChild (QSharedPointer< Region > child)
	Adds a child to the current Region. More...

bool	reassignChild (QSharedPointer< Region > child)
	Reassigns the child w.r.t its ID. This function is needed if an element was converted (e.g. table cell to text block) but needs to be updated. If the child ID is found, the children of the existing region are replaced by those of child and true is returned. More...

void	addUniqueChild (QSharedPointer< Region > child, bool update=false)
	Adds the child if it does not exist already. If update is true, the duplicate element is updated, otherwise nothing happens if the child exists already. More...

void	removeChild (QSharedPointer< Region > child)
	Removes the child specified. More...

void	removeAllChildren ()

void	setChildren (const QVector< QSharedPointer< Region > > &children)
	Sets the child regions. More...

QVector< QSharedPointer< Region > >	children () const
	Children of this instance. More...

virtual QString	childrenToString () const
	Returns a string with all attributes of the Region's children. More...

virtual void	readAttributes (QXmlStreamReader &reader)

virtual void	writeChildren (QXmlStreamWriter &writer) const
	Writes the Region's children to the XML stream. More...

void	createElement (QXmlStreamWriter &writer) const
	Creates the element. After a call to this method, attributes can be appended to the element. More...

void	writePolygon (QXmlStreamWriter &writer) const
	Writes the polygon. This is a convenience function for derived classes. Typically writePolygon is called after all (additional) attributes of the current element are set. More...

virtual bool	operator== (const Region &r1)
	Compare operator. Returns true if both regions have the same type and polygon. More...

Constructor & Destructor Documentation

rdf::TextRegion::TextRegion ( const Type & type = Type::type_unknown )

Initializes a new instance of the TextRegion class. This class represents Text regions (Region::type_text_region).

Member Function Documentation

void rdf::TextRegion::draw	(	QPainter &	p,
		const RegionTypeConfig &	config
	)		const

overridevirtual

Draws the TextRegion to the Painter.

Parameters

p	The painter.
config	The configuration (e.g. color of the Region).

Reimplemented from rdf::Region.

bool rdf::TextRegion::read ( QXmlStreamReader & reader )

overridevirtual
