static DtLocationEntryWidget* DtTerrainLocationEntryWidget::create	(	QWidget *	parent = NULL,
		const Qt::WindowFlags &	flags = 0
	)		[static]

Reimplemented from DtLocationEntryWidget.

virtual void DtTerrainLocationEntryWidget::convertFromSource	(	const DtPoint &	pnt,
		const DtCoordSys &	newSys,
		DtStringLocation &	out
	)		[virtual]

Converts from source coordinate system (as found in the terrain database, if it exists) to supplied coordinate system.

Assumes the point coming is in in local (database) coordinates

Reimplemented from DtLocationEntryWidget.

virtual void DtTerrainLocationEntryWidget::convertToSource	(	const DtStringLocation &	in,
		double &	x,
		double &	y,
		double &	z
	)		[virtual]

Converts from current coordinate system to coordinate system of database (if there is a terrain database).

Default simply copies to result
