Class ZoomingRelativeHandleLocator

java.lang.Object

org.eclipse.draw2d.RelativeLocator

org.eclipse.graphiti.ui.internal.util.draw2d.ZoomingRelativeHandleLocator

All Implemented Interfaces:

org.eclipse.draw2d.Locator

public class ZoomingRelativeHandleLocator
extends org.eclipse.draw2d.RelativeLocator
implements org.eclipse.draw2d.Locator

A Locator, which sets the target bounds depending on the reference figure bounds according to the following rules:

• The handle-insets are used to expand/shrink the reference figure bounds, at the beginning of the calculation. They are adjusted with the current zoom-level.
• The location can be one of the north-south-east-west constants in PositionConstants. It describes the side/corner of the reference figure bounds at which the target is located.
• The handle-dimension defines the dimension of the target bounds. They are adjusted with the current zoom-level.

Constructor Detail

ZoomingRelativeHandleLocator

public ZoomingRelativeHandleLocator(org.eclipse.draw2d.IFigure reference,
                                    IConfigurationProvider configurationProvider,
                                    int location,
                                    org.eclipse.draw2d.geometry.Dimension handleDimension,
                                    org.eclipse.draw2d.geometry.Dimension handleInsets)

Creates a new ZoomingInsetsHandleLocator.

Parameters:

reference - The target bounds are calculated depending on this reference figure.

configurationProvider - The configuration provider which can be used to access the environment.

location - The location can be one of the north-south-east-west constants in PositionConstants.

handleDimension - The dimension of the target bounds.

handleInsets - The insets to apply to the reference figure bounds.
