示例

public override DslDiagrams::MouseAction GetPotentialMouseAction(System.Windows.Forms.MouseButtons mouseButtons, DslDiagrams.PointD point, DslDiagrams::DiagramHitTestInfo hitTestInfo)
{
    DslDiagrams::LinkShape linkShape = hitTestInfo.HitDiagramItem.Shape as DslDiagrams::LinkShape;

    DslDiagrams::MouseAction action = null;

    if ((linkShape != null) && (hitTestInfo.DiagramClientView.Selection.Count == 1) &&
             (anchorPoint != null))
    {
        action = this.SequenceDiagram.AnchorKeyPointAction;
    }

    else if ((mouseButtons == MouseButtons.Left || mouseButtons == MouseButtons.None) &&
(linkShape != null) && (hitTestInfo.DiagramClientView.Selection.Count == 1) &&
(hitTestInfo.DiagramClientView.Selection.PrimaryItem.Shape is LinkShape) &&
(hitTestInfo.DiagramClientView.Selection.PrimaryItem.Shape == linkShape) &&

}
    
    else
    {
        action = base.GetPotentialMouseAction(mouseButtons, point, hitTestInfo);
