const [virtual]

virtual void DtTMViewportExtents::changeWindowSize	(	const DtDisplaySize &	s,
		bool	redraw = true,

	)		[virtual]

After the initial init, use this function to resize the window without zooming.

virtual void DtTMViewportExtents::resizeToGlobalView	(	const DtDisplaySize &	s,
		bool	redraw = true
	)		[virtual]

Same as above, but force a global view when resizing.

This causes the same thing as changeWindowSize followed by a resetToGlobalView but joins them both so the database gets redrawn only once

virtual void DtTMViewportExtents::windowFromDatabase	(	DtDisplayPoint &	xp,
