Detailed Description

A Slider wraps a Gtk::Scale widget in the UI and manages flexible max/min values, responding to broadcast events.

Constructor & Destructor Documentation

mc::Slider::Slider	(	BaseObjectType *	cobject,
		const Glib::RefPtr< Gtk::Builder > &	refGlade
	)

Constructor for the Gtk::Builder

Parameters

cobject	A base object typedef
refGlade	A reference to the builder.

mc::Slider::~Slider

(

)

Destructor

Member Function Documentation

void mc::Slider::block

(

bool

b

)

Stop/start broadcasting events

Parameters

b	True allows broadcasts, false dis-allows.

void mc::Slider::fix

(

)

Freezes the slider at the current value.

std::string mc::Slider::get_value ( )

virtual

Returns a string representation of the current value of the Interface.

Implements mc::Interface.

void mc::Slider::notify ( Event *  e )

virtual

Update the Interface about change events. Used by broadcaster.

Parameters

e	The event object

Implements mc::Subscriber.

void mc::Slider::on_value_changed

(

)

Generates a change event and sends it to Broadcaster.

void mc::Slider::populate

(

)

Populates the UI with values from the datastore.

void mc::Slider::set_columns

(

std::vector< std::string >

c

)

The columns to use for setting max and min values.

Parameters

c	Column names ('max_sfpm' etc.)

void mc::Slider::set_marks

(

)

Sets any marks that this Slider contains in the UI.

void mc::Slider::set_marks

(

std::map< double, std::string >

m

)

Overloaded set_marks is used to provide constant mark values to add to the Gtk::Scale.

Parameters

m	A map of double (position) and string (label) values.

void mc::Slider::set_references	(	std::vector< mc::Interface * >	s,
		std::vector< mc::Interface * >	e
	)

Add references to the interface that will trigger the Slider to update. Slider uses two sets of references and a scaler value to move the available range of values between the two.

Parameters

s	A vector of Interfaces to use as a reference
e	A vector of Interfaces to use as a reference

void mc::Slider::set_scaler

(

mc::Interface *

i

)

The scaler is an Interface that is expected to be a value between 0-100 and is used to change the max and min values of this slider.

Parameters

i	The Interface to use as a scaler.

void mc::Slider::set_value	(	double	max,
		double	min,
		double	val
	)

Sets the max, min and current position of the Slider.

void mc::Slider::set_value ( std::string  s )

virtual

Sets a value from a string (converts to double).

Implements mc::Interface.

void mc::Slider::unfix

(

)

Unfreezes the slider.
