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

Class 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.

        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.
