Member Function Documentation

virtual void DtTMSymbolUpdater::init ( DtTMArea * area )

virtual

Initializes the updater by setting up the update callbacks.

Reimplemented in DtTerrainSymbolUpdater, and DtFormationSymbolUpdater.

virtual void DtTMSymbolUpdater::setViewportExtents ( const DtTMViewportExtents * )

virtual

Connects this symbol updater to a specific viewport extents object which is used to do screen->database conversions.

virtual const DtTMViewportExtents* DtTMSymbolUpdater::viewportExtents ( ) const

virtual

virtual void DtTMSymbolUpdater::setDisplayOptions ( const DtTMDisplayOptions * o )

virtual

Connects this symbol updater to the app display options which is used to determine what and how some symbols should be drawn.

virtual const DtTMDisplayOptions* DtTMSymbolUpdater::displayOptions ( ) const

virtual

virtual void DtTMSymbolUpdater::updateSymbol	(	DtSymbol &	,
		const DtModelData &
	)

virtual

Update a symbol with the data.

This is really the only function that you should call unless you know specifically what type of symbol and what type of data you have. It uses dynamic casts to figure out what type of symbol you have in order to do the right thing.

virtual void DtTMSymbolUpdater::setViewDriver ( const DtViewDriver * driver )

virtual

Sets the view driver that will be using this symbol updater.

virtual void DtTMSymbolUpdater::setResetLabelPositions ( bool b )

virtual

virtual int DtTMSymbolUpdater::defaultLineWidth	(	const DtEnvironmentalModelData &	d,
		const DtTMDisplayOptions *	opt
	)		const

virtual

virtual void DtTMSymbolUpdater::addSymbolUpdateCallback	(	QString	type,
		DtPostSymbolUpdateCallback	fcn,
		void *	usr = `NULL`
	)

virtual

Accessors to add/remove callbacks for model data types.

virtual void DtTMSymbolUpdater::removeSymbolUpdateCallback	(	QString	type,
		DtSymbolUpdatorCallback	fcn
	)

virtual

virtual void DtTMSymbolUpdater::addPostUpdateCallback	(	int	iType,
		DtPostSymbolUpdateCallback	fcn,
		void *	usr
	)

virtual

Adds a callback to be invoked any time a symbol is updated.

Use the type to specify the type that you want the callback for or -1 for all types

virtual void DtTMSymbolUpdater::removePostUpdateCallback	(	int	iType,
		DtPostSymbolUpdateCallback	fcn,
		void *	usr
	)

virtual

Removes the post create callback if all three items match.

virtual void DtTMSymbolUpdater::removeAllPostUpdateCallbacks ( )

virtual

Removes all post update callbacks.

Only call if you really want to disable these callbacks as they cannot be replaced without executing the code that originally added them

virtual QPolygon* DtTMSymbolUpdater::createScreenPtsFromDB ( const QVector< DtPoint > * dbPoints ) const

virtual

Reimplemented in DtFormationSymbolUpdater.

virtual QPolygon* DtTMSymbolUpdater::createScreenPtsFromDB ( const QList< DtVector > * dbPoints ) const
