int Eaagles::Instruments::SymbolLoader::getMaxSymbols

(

)

const [inline]

Get the maximum number of symbols.

int Eaagles::Instruments::SymbolLoader::getSymbolIndex

(

const BasicGL::LcGraphic *const

mySymbol

)

const

symbol index is one based, so we have to use the n-1 position in the array

bool Eaagles::Instruments::SymbolLoader::clearLoader

(

)

Clears all of our symbols out.

int Eaagles::Instruments::SymbolLoader::getSymbolType

(

const int

idx

)

const

return the numeric id for this symbol

int Eaagles::Instruments::SymbolLoader::getNumberOfActiveSymbols

(

)

const

returns the count of active symbols

SlSymbol * Eaagles::Instruments::SymbolLoader::getSymbol

(

const int

idx

)

gets a symbol pointer based on the index passed

int Eaagles::Instruments::SymbolLoader::addSymbol	(	const int	nType,
		const char *const	id,
		int	specName = -1
	)			[virtual]

or zero if not added.

adds a symbol to our array list; returns the symbol's index; range [ 1 .. getMaxSymbols() ]

bool Eaagles::Instruments::SymbolLoader::updateSymbolPositionXY	(	const int	idx,
		const double	xPos,
		const double	yPos
	)			[virtual]

actual X Y from the ownship instead of from the reference, you must subtract ownship's xy (NED) from the track's xy (NED) before using this function.

bool Eaagles::Instruments::SymbolLoader::updateSymbolPositionXYAircraft	(	const int	idx,
		const double	xPos,
		const double	yPos
	)			[virtual]

Does the same as updateSymbolXY, only here we do not rotate our symbol before drawing, because we are assuming we are getting an aircraft off-the-nose, off-the-wing set of values.

bool Eaagles::Instruments::SymbolLoader::updateSymbolPositionLL	(	const int	idx,
		const double	lat,
		const double	lon
	)			[virtual]

update Lat lon position of symbol

bool Eaagles::Instruments::SymbolLoader::updateSymbolHeading	(	const int	idx,
		const LCreal	hdg
	)			[virtual]

update the symbol's heading

bool Eaagles::Instruments::SymbolLoader::updateSymbolValue	(	const int	idx,
		Basic::LcObject *const	value
	)			[virtual]

update the symbol's value

bool Eaagles::Instruments::SymbolLoader::updateSymbolSelectName	(	const int	idx,
		const int	newSN
	)			[virtual]

update the symbol's select name

bool Eaagles::Instruments::SymbolLoader::removeSymbol

(

const int

idx

)

[virtual]

removes a symbol from the array list

bool Eaagles::Instruments::SymbolLoader::setShowInRangeOnly

(

const bool

x

)

[virtual]

determines if we show our symbols outside the range ring

bool Eaagles::Instruments::SymbolLoader::updateSymbolText	(	const int	idx,
		const char *	name,
		const char	newString[]
	)			[virtual]

update the symbol's text. You specify which name you wish for the symbol loader to look for (const char* name), and it will find that asciiText and change the text accordingly. If you do not supply a valid name, or if the name is not found, it will return false For example, if you wish to update a symbol with a "lower" text name to the word "hello", you would call updateSymbolText(1, "lower", "hello"); If no component exists with the name "hello", then false is returned. '1' is the symbol index number.

bool Eaagles::Instruments::SymbolLoader::updateSymbolText	(	const int	idx,
		const char *	name,
		const LCreal	newVal
	)			[virtual]

Update symbol text with an LCreal.

bool Eaagles::Instruments::SymbolLoader::setSymbolFlashRate	(	const int	idx,
		const char *	name,
		const LCreal	flashRate
	)			[virtual]

set symbol and child components flashing

bool Eaagles::Instruments::SymbolLoader::setSymbolVisible	(	const int	idx,
		const char *	name,
		bool	visibility
	)			[virtual]

set symbol visible / invisible

bool Eaagles::Instruments::SymbolLoader::setSymbolScale	(	const int	idx,
		const char *	name,
		const LCreal	scale
	)			[virtual]

set symbol and child components scale

bool Eaagles::Instruments::SymbolLoader::changeSymbolType	(	const int	nType,
		const int	idx
	)			[virtual]

change an existing symbol type to another type

bool Eaagles::Instruments::SymbolLoader::changeSymbolColor	(	const int	idx,
		const char *	name = 0,
		const Basic::LcColor *	cobj = 0
	)			[virtual]

update the symbol's color

bool Eaagles::Instruments::SymbolLoader::changeSymbolColor	(	const int	idx,
		const char *	name = 0,
		const Basic::LcIdent *	cobj = 0
	)			[virtual]

update the symbol's color based on Ident

void Eaagles::Instruments::SymbolLoader::draw

(

)

[virtual]

BasicGL::LcGraphic interface.

Reimplemented from Eaagles::BasicGL::LcPage.

void Eaagles::Instruments::SymbolLoader::updateData

(

const LCreal

dt = 0.0f

)

[virtual]

Basic::LcComponent interface.

int Eaagles::Instruments::SymbolLoader::getSymbols	(	SPtr< SlSymbol > *const	newSyms,
		const int	max
	)			[protected]

Gets our list of symbols, and returns the number of symbols.
