Class SubgraphTreeLayoutManager

The SubgraphTreeLayoutManager is a special type of the DirectedTreeLayoutManager that enables the sub nodes of a diagram layout tree to have an orientation that is distinct from the parent node. The sub graph orientation is specified using a SubgraphPreferredLayout event that the layout manager raises before positioning each set of sub nodes in the graph.

Declaration
public SubgraphTreeLayoutManager(Model model, float fRotationDegree, int nVerticalOffset, int nHorizontalOffset)
Parameters
Type Name Description
Model model

The diagram Model.
System.Single fRotationDegree

The root to child orientation to be used for the tree.
System.Int32 nVerticalOffset

Specifies the vertical distance between adjacent nodes.
System.Int32 nHorizontalOffset

Methods

DoGraphLayout()

Applies the layout strategy on the diagram.

Declaration
protected override void DoGraphLayout()
Overrides

MakeChangingDirectionGraphLayout(Graph)

Declaration
protected void MakeChangingDirectionGraphLayout(Graph graphToLayout)
Parameters
Type Name Description
Graph graphToLayout

The graph to layout.

MakeChangingDirectionLayout(Graph)

Performs the graph layout.

public event SubgraphPreferredLayoutEventHandler SubgraphPreferredLayout
Event Type
Type
SubgraphPreferredLayoutEventHandler
Remarks

Handling the SubgraphPreferredLayout event provides users with the ability to specify a distinct orientation and bounds for the sub nodes.
