public class TLcdMagneticNorthGXYController
extends ALcdGXYSmartController
implements ILcdGXYChainableController

When active on a ILcdGXYView, this ILcdController will catch each mouseClicked and try to modify the properties of the ILcdProjection currently on the ILcdGXYView accordingly.

More specifically it re-centers the projection at the touched point and it will rotate the map such that the direction to the magnetic north (what a compass would indicate) is equal to the (vertical) direction to the top of your screen.

This controller will also display a tool tip showing the declination at the point under the mouse cursor, see formatToolTip..

Note that the user of this class is responsible for giving this object a correctly initialized magnetic north map.

startInteraction

public void startInteraction(ILcdGXYView aView)

Description copied from class: ALcdGXYController

Sets up the controller to receive input through the view passed.

All ILcdGXYView implementations that support interaction call this method when the controller has been made active with setGXYController on the view, so this method shouldn't normally be called directly. Note that most view implementations add the controller as listener if appropriate before calling this method.
