Class AbstractOpiBuilderAnchor

java.lang.Object
org.eclipse.draw2d.ConnectionAnchorBase
org.eclipse.draw2d.AbstractConnectionAnchor
org.csstudio.opibuilder.editparts.AbstractOpiBuilderAnchor
All Implemented Interfaces:
org.eclipse.draw2d.AncestorListener, org.eclipse.draw2d.ConnectionAnchor
Direct Known Subclasses:
FixedPositionAnchor, PolyGraphAnchor
public abstract class AbstractOpiBuilderAnchor extends org.eclipse.draw2d.AbstractConnectionAnchor
We have multiple implementations of the Anchor, and the FixedPointsConnectionRouter needs to know orientation in which the connector connects to the widget in order to correctly calculate the route. This becomes especially important once the widgets change positions (are animated) through some action.

  • Method Details

    • fixZoomEdgeRounding

      public static void fixZoomEdgeRounding(org.eclipse.draw2d.geometry.Point point, org.eclipse.draw2d.IFigure owner)

      In case of linking container zoom edge cases appear when linked OPI contains elements staring on point(0,0). When zooming some anchor points get out of linked container box. This causes broken connection, as anchor is no longer found.

      This is fixed by moving the anchor back into the bounds of linking container.

      Parameters:
      point - - reference to anchor point
      owner - - reference to the figure

    • getOrientation

      public abstract AbstractOpiBuilderAnchor.ConnectorOrientation getOrientation()
      Returns:
      The direction in which the connection is oriented at this anchor, if the Manhattan router is being selected
