namespace yav class ScaleCamera : public Activable, public DPOwner<Scalable>, public Pointed<ScaleCamera>

an interface class defining generic commands for a scale connected to a set of scalables

Inheritance:

Public Methods

virtual void	setLabel (const TclString& lab) set scale label
virtual void	setBounds (double min, double max) set scale bounds
virtual void	set (double val) set a new value to scale
virtual void	to (double val) set a new value to scale but do not call scale command
virtual void	configureToMax (void) set bounds of the scale to min/max of all managed scalables
virtual double	get (void) const returns scale value
virtual void	checkValue (void) checks if the current value is between the min and max value; if not then set the value to (min+max)/2
virtual void	on (void) activates scale, overloads Activate::on
virtual void	dying (const Scalable *elt) callback function for a DPList element being removed
virtual void	operator+= (Scalable *sclb) throw(DPList<Scalable>::NullPointer, DPList<Scalable>::AlreadyInList) adds a new scalable to scale object
virtual void	operator-= (Scalable *sclb) throw(DPList<Scalable>::NotFound) removes a scalable from a scale object
virtual void	reset (Scalable *cam, const TclString& lab) reset scale bounds and label
const DPList <Scalable> &	getObjects (void) const returns iterator on handled scalable list
virtual const std::type_info&	getType (void) const returns scale type
virtual void	activation (void) Activation callback: activates scale up and down

Public

	constructor ScaleCamera () builds a scale object ScaleCamera (std::list<Scalable *>& list) builds a scale object that manages given list of scalables ScaleCamera (Scalable *elt) builds a scale object that manages a given scalable
	destructor virtual ~ScaleCamera () destroys associated TCL scale

constructor

ScaleCamera()

builds a scale object

ScaleCamera(std::list<Scalable *>& list)

builds a scale object that manages given list of scalables

Parameters:

list - object this scale commands

ScaleCamera(Scalable *elt)

builds a scale object that manages a given scalable

Parameters:

list - object this scale commands

destructor

virtual ~ScaleCamera()

destroys associated TCL scale

virtual void setLabel(const TclString& lab)

set scale label

Parameters:

lab - new scale label

virtual void setBounds(double min, double max)

set scale bounds

Parameters:

min - scale min value
max - scale min value

virtual void set(double val)

set a new value to scale

Parameters:

val - new scale value

virtual void to(double val)

set a new value to scale but do not call scale command

Parameters:

val - new scale value

virtual void configureToMax(void)

set bounds of the scale to min/max of all managed scalables

virtual double get(void) const

returns scale value

virtual void checkValue(void)

checks if the current value is between the min and max value; if not then set the value to (min+max)/2

virtual void on(void)

activates scale, overloads Activate::on

virtual void dying(const Scalable *elt)

callback function for a DPList element being removed

Parameters:

elt - element being removed

virtual void operator+=(Scalable *sclb) throw(DPList<Scalable>::NullPointer, DPList<Scalable>::AlreadyInList)

adds a new scalable to scale object

Parameters:

sclb - scalable to command

virtual void operator-=(Scalable *sclb) throw(DPList<Scalable>::NotFound)

removes a scalable from a scale object

Parameters:

sclb - scalable to release

virtual void reset(Scalable *cam, const TclString& lab)

reset scale bounds and label

Parameters:

cam - calling viewer
lav - new scale label (if not EMPTY_STRING)

const DPList <Scalable> & getObjects(void) const

returns iterator on handled scalable list

virtual const std::type_info& getType(void) const

returns scale type

virtual void activation(void)

Activation callback: activates scale up and down
