public void detachView(IlvManagerView view)

This function is called when a view is removed from the manager to which this instance is attached.

_getZoomTransformer

public IlvTransformer _getZoomTransformer()

Returns the zoom transform. This transform converts stationary coordinates to manager coordinates. Only to be called while manager is locked.

Internal method or field: do not use!

_getInverseZoomTransformer

public IlvTransformer _getInverseZoomTransformer()

Returns the inverse of the zoom transform. This transform converts manager coordinates to stationary coordinates. Only to be called while manager is locked.

Internal method or field: do not use!

_setZoomTransformer

public void _setZoomTransformer(IlvTransformer t)

Sets the zoom transform.

Internal method or field: do not use!

_composeZoomTransformer

public void _composeZoomTransformer(IlvTransformer t)

Modifies the zoom transform: _zoomTransformer := _zoomTransformer t. Only to be called while _manager is locked; this ensures that it is not called during an IlvManager.applyToObject(some IltcCompositePart).

Internal method or field: do not use!

composeInverseZoomTransformerWith

public IlvTransformer composeInverseZoomTransformerWith(IlvTransformer t)

Returns the composition of the inverse zoom transformer and the argument.

Parameters:

t - a IlvTransformer

Returns:

_zoomTransformer^(-1) t

Internal method or field: do not use!

getZoomPolicy

public IltZoomPolicy getZoomPolicy()

Internal method or field: do not use!

removeZoomPolicy

public void removeZoomPolicy()

Sets the zoom policy back to the default.

Internal method or field: do not use!

AddZoomSupport

public static void AddZoomSupport(IlvManagerView view)

Adds support for zooming a view.

Note: When a zoom change occurs, ILOG JTGO will change the coordinates of JViews objects present in the manager by calling IlvGraphic.applyTransform on each of them.

Note: When multiple IlvManagerView instances are attached to the same IlvManager, AddZoomSupport should be called only for one of these views. It will have an effect on all of these views, however.

RemoveZoomSupport(ilog.views.IlvManagerView)

RemoveZoomSupport

public static void RemoveZoomSupport(IlvManagerView view)

Removes support for zooming a view.

This function must be called before another view can get zooming support on the same IlvManager.

Note: This function does not move back the JViews objects to their original coordinates before AddZoomSupport was applied. If this is desired, you have to change the view's zoom transformer to a translation before calling RemoveZoomSupport.

AddZoomListener

public static void AddZoomListener(IlvManager manager,
                                   IltcZoomListener listener)

Adds a zoom listener to an IlvManager.

RemoveZoomListener

public static void RemoveZoomListener(IlvManager manager,
                                      IltcZoomListener listener)

Removes a zoom listener from an IlvManager.

getZoomTransformer

public IlvTransformer getZoomTransformer()

Returns the zoom transform of the associated manager. It transforms conceptual to actual manager coordinates. If no AddZoomSupport has been added to a view attached to the manager, null is returned, which stands for the identity transform.

fireSelectionEventSeriesBegin

public void fireSelectionEventSeriesBegin()

Broadcasts the beginning of a series of selection change events in this manager.

Internal method or field: do not use!

fireSelectionEventSeriesEnd

public void fireSelectionEventSeriesEnd()

Broadcasts the end of a series of selection change events in this manager.

Internal method or field: do not use!

fireTreeSelectionEventSeriesBegin

public void fireTreeSelectionEventSeriesBegin()

Broadcasts the beginning of a series of selection change events in this manager or a submanager.

Internal method or field: do not use!

fireTreeSelectionEventSeriesEnd

public void fireTreeSelectionEventSeriesEnd()

Broadcasts the end of a series of selection change events in this manager or a submanager.

Internal method or field: do not use!

dispose

public void dispose()

Cleans up the manager, and drops references to objects, to help garbage collection.

Note: After calling this function, this manager is not functional any more.
