Member Function Documentation

LCreal Eaagles::Instruments::BearingPointer::getBearingRad

(

)

[inline]

get function - returns the value of bearing in radians

LCreal Eaagles::Instruments::BearingPointer::getBearingDeg

(

)

[inline]

get function - returns the value of bearing in degrees

BasicGL::LcGraphic* Eaagles::Instruments::BearingPointer::getHeadGraphic

(

)

[inline]

Returns the head graphic if it exists else returns 0.

BasicGL::LcGraphic* Eaagles::Instruments::BearingPointer::getTailGraphic

(

)

[inline]

Returns the tail graphic if it exists else returns 0.

bool Eaagles::Instruments::BearingPointer::setBearingRad

(

const LCreal

newB

)

Set function - sets the bearing value in radians.

bool Eaagles::Instruments::BearingPointer::setBearingDeg

(

const LCreal

newB

)

Set function - sets the bearing value in degrees.

void Eaagles::Instruments::BearingPointer::drawFunc

(

)

[virtual]

BasicGL::LcGraphic interface.

Reimplemented from Eaagles::BasicGL::LcGraphic.

void Eaagles::Instruments::BearingPointer::draw

(

)

[virtual]

BasicGL::LcGraphic interface - draws the object(s) using the graphic matrix.

Reimplemented from Eaagles::Instruments::CompassRose.

void Eaagles::Instruments::BearingPointer::updateData

(

const LCreal

dt = 0

)

[virtual]

Basic::LcComponent interface.

Reimplemented from Eaagles::Instruments::CompassRose.

virtual bool Eaagles::Instruments::BearingPointer::event	(	const int	key,
		Basic::LcObject *const	obj = 0
	)			[virtual]

Sends the 'event' message with optional argument 'obj'. Returns true if the 'event' has been received and used. Derived classes will provided event() handlers, as needed. Event() can be called from an updateTC() routines, therefore,the event message must be processed quickly (i.e., no waits)

Reimplemented from Eaagles::Instruments::CompassRose.

bool Eaagles::Instruments::BearingPointer::setSlotHeadGraphic

(

const BasicGL::LcGraphic *const

newH

)

[protected, virtual]

slot function - sets the head graphic for the bearing pointer

bool Eaagles::Instruments::BearingPointer::setSlotTailGraphic

(

const BasicGL::LcGraphic *const

newT

)

[protected, virtual]

slot function - sets the tail graphic for the bearing pointer

bool Eaagles::Instruments::BearingPointer::onUpdateRadBearingPointer

(

const Basic::LcAngle *const

msg

)

[private]

event handler

bool Eaagles::Instruments::BearingPointer::onUpdateRadBearingPointer

(

const Basic::LcNumber *const

msg

)

[private]

event handler for update bearing angle (radians)

bool Eaagles::Instruments::BearingPointer::onUpdateDegBearingPointer

(

const Basic::LcNumber *const

msg

)

[private]

event handler for update bearing angle (degrees)
