[virtual]

Pure virtuals that need to be implemented in order to be a grid line drawer.

Reimplemented from DtDatabaseGridLineDrawer.

virtual QString DtUtmGridLineDrawer::labelForHorizLine	(	const DtPoint &	val,
		double	increment,
		const DtTerrainDatabase *	db
	)		[protected, virtual]

Override to provide different labels for the vertical or horizontal grid lines.

The "buf" variable should contain the label the be displayed

Reimplemented from DtDatabaseGridLineDrawer.

virtual QString DtUtmGridLineDrawer::labelForVertiLine	(	const DtPoint &	val,
		double	increment,
		const DtTerrainDatabase *	db
	)		[protected, virtual]

Since horizontal and vertical labels are the same, default implementation calls labelForHorizLine.

Reimplemented from DtDatabaseGridLineDrawer.

virtual int DtUtmGridLineDrawer::type

(

)

const [protected, virtual]

This is only to try and identify one grid line drawer from another to prevent unnecessary terrain redraw as a coordinate system choice changes.

Reimplemented from DtDatabaseGridLineDrawer.
