                // Outer part of quick command.
                Shape = this.Resources["Ellipse"],
               // appearence of shape.
                ShapeStyle = this.Resources["QuickCommandstyle"] as Style,
                //Inner part of quick command and it allows to host any UI elements
                Content =
                    "M3.7399902,0L16,12.258972 28.26001,0 32,3.7399902 19.73999,16 32,28.258972 28.26001,32 16,19.73999 3.7399902,32 0,28.258972 12.26001,16 0,3.7399902z",
                Command = (Diagram.Info as IGraphInfo).Commands.Cut

            // Adding new QuickCommand object in Commands collection

By default QuickCommand will host on Node. VisibilityMode property is to define the host of the QuickCommand on either Node or Connector or both.


QuickCommand can be aligned relative to boundaries of the Node or segments of the Connector.

  • OffsetX and OffsetY property of QuickCommand is used to align the QuickCommand based on fractions. The default value is 0.5.
  • HorizontalAlignment and VerticalAlignment properties are used to align the quick commands for horizontal and vertical positions.
  • Margin is an absolute value used to add some blank space in any one of its four sides.

The Alignment of QuickCommand is similar to Annotation Alignment.
