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
