Package com.luciad.view.lightspeed.controller.navigation

Class TLspRecenterProjectionController

java.lang.Object

com.luciad.view.lightspeed.controller.ALspController

com.luciad.view.lightspeed.controller.navigation.TLspRecenterProjectionController

All Implemented Interfaces:

ILcdAWTEventListener, ILspController

public class TLspRecenterProjectionController
extends ALspController

When active on an ILspView, this ILspController will try to center the ILcdProjection that is currently set on the ILspView on the location that was clicked.

For example, if the ILcdProjection is an ILcdAzimuthal projection, this ILspController will transform the clicked screen point into a LonLat coordinate and use it to set the originLon and originLat properties of the ILcdAzimuthal projection.

Note that the map recenter controller will only work on a view that has an ILcdGridReference as a world reference. For any other type of world reference, the map recenter controller will do nothing.

The map recenter controller only supports the following projections:

• ILcdAzimuthal
• ILcdCylindrical
• ILcdTransverseCylindrical
• ILcdObliqueCylindrical
• ILcdConic
• TLcdPolyconic

2012.0

Method Details

handleAWTEventImpl

public AWTEvent handleAWTEventImpl(AWTEvent aEvent)

Description copied from class: ALspController

Called by handleAWTEvent. Returns null when the controller consumed the event or a partially consumed event when the controller partially consumed the event (which could happen with TLcdTouchEvents). When the controller did not use the given event, it is returned unaltered.

Specified by:

handleAWTEventImpl in class ALspController

Parameters:

aEvent - the event to be handled.

Returns:

null when the input event was consumed, the (possibly modified) input event when it was (partially) consumed.

handleFXEventImpl

public Event handleFXEventImpl(Event aEvent)

Description copied from class: ALspController

Called by handleFXEvent. Returns null when the controller consumed the event. When the controller did not use the given event, it is returned unaltered.

Overrides:

handleFXEventImpl in class ALspController

Parameters:
