Member Function Documentation

virtual bool DtCoordinateSystemCollection::init

(

)

[virtual]

Adds all default converters by initially adding all items found in coordUtil.h Unit converter must be set to allow for correct label creation for X, Y and Z labels (handed down to the coordinate systems)

static DtCoordinateSystemCollection* DtCoordinateSystemCollection::create

(

const DtUnitDisplayManager *

units

)

[static]

Creates a new instance of this object.

Reimplemented in DtTerrainCoordinateSystemCollection.

virtual const DtCoordinateSystemDict& DtCoordinateSystemCollection::coordinateSystemCollection

(

)

const [virtual]

Returns the internal unit converter collection.

virtual DtCoordinateSystemDict& DtCoordinateSystemCollection::coordinateSystemCollection

(

)

[virtual]

virtual void DtCoordinateSystemCollection::fillComboBox	(	QComboBox *	box,
		QList< DtCoordSys > *	showOnly = NULL
	)		const [virtual]

Fills the combo box with all items found in the collection.

If showOnly is defined, will only show the items that are in that value list

virtual void DtCoordinateSystemCollection::fillGridLineSelection	(	const DtCoordSys &	system,
		const QString &	unit,
		QComboBox *	combo
	)		[virtual]

Fills the combo box with grid line spacing choices.

Passes responsibility down to unit converter that is represented by the particular coordinate system

virtual QString DtCoordinateSystemCollection::gridLineTextForFrequency	(	const DtCoordSys &	system,
		const QString &	unit,
		double	frequency
	)		[virtual]

Returns the grid line text for the specified frequency.

Passes down to specified coordinate system

virtual double DtCoordinateSystemCollection::gridLineFrequencyForText	(	const DtCoordSys &	system,
		const QString &	unit,
		const QString &	text
	)		[virtual]

Returns the grid line frequency for the specified text.

Passes down to specified coordinate system

virtual QString DtCoordinateSystemCollection::xLabelFor

(

const DtCoordSys &

system

)

const [virtual]

Calls down to coordinate system referenced by system for the labels.

virtual QString DtCoordinateSystemCollection::yLabelFor

virtual void DtCoordinateSystemCollection::setPrecision	(	const DtCoordSys &	s,
		int	,
		bool	signal = true
	)		[virtual]

Get/set precision for the specified coordinate system.

Note that if the precision is set directly in the coordinate system object, it will not be emitted as being changed. Returns true if precision was changed. If signal is false, will not emit signal on change

const [virtual]

virtual void DtCoordinateSystemCollection::restoreDefaults

(

)

[virtual]

Restores all precision settings for all current coordinate systems to 2.

virtual void DtCoordinateSystemCollection::addCoordinateSystem	(	const DtCoordSys &	unit,
		DtCoordinateSystem *	obj
	)		[virtual]

These routines call down to the myCoordinateSystem version of the methods.

system

)

const [virtual]

virtual void DtCoordinateSystemCollection::automaticallyUpdateComboBox

(

QComboBox *

)
