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.
