Method Details

getLayer

public ILayer getLayer()

Specified by:

getLayer in interface IVisualChangeEvent

Returns:

the layer that the visible change event is originating from.

convertToLocal

public boolean convertToLocal(ILayer localLayer)

Description copied from interface: ILayerEvent

Convert the column/row positions carried by the event to the layer about to handle the event.

Specified by:

convertToLocal in interface ILayerEvent

Parameters:

localLayer - layer about to receive the event

Returns:

TRUE if successfully converted, FALSE otherwise

getChangedPositionRectangles

public Collection<org.eclipse.swt.graphics.Rectangle> getChangedPositionRectangles()

Specified by:

getChangedPositionRectangles in interface IVisualChangeEvent

Returns:

the position rectangles that have changed and need to be redrawn. If no rectangles are returned, then the receiver should assume that the entire layer is changed and will need to be redrawn.

isHorizontalStructureChanged

public boolean isHorizontalStructureChanged()

Specified by:

isHorizontalStructureChanged in interface IStructuralChangeEvent

isVerticalStructureChanged

public boolean isVerticalStructureChanged()

Specified by:

isVerticalStructureChanged in interface IStructuralChangeEvent

getColumnDiffs

public Collection<StructuralDiff> getColumnDiffs()

Specified by:

getColumnDiffs in interface IStructuralChangeEvent

getRowDiffs

public Collection<StructuralDiff> getRowDiffs()

Specified by:

getRowDiffs in interface IStructuralChangeEvent

cloneEvent

public ILayerEvent cloneEvent()

Specified by:

cloneEvent in interface ILayerEvent

Returns:

A cloned copy of the event. This cloned copy is provided to each listener.
