Method Detail

adjustGeometry

public static final void adjustGeometry(VisualGraphView vgv,
                                        VisualNode vn)

Adjusts the geometry of the given VisualNode object to the coordinate system of the given VisualGraphView object.
In case the given VisualNode object is a VisualSubgraph instance its children and grandchildren are recursively adjusted as well.

Parameters:

vgv - the VisualGraphView object to adjust the geometry of the given VisualNode object to

vn - the VisualNode object to adjust the geometry for

adjustGeometry

public static final void adjustGeometry(VisualGraphView vgv,
                                        VisualEdge ve)

Adjusts the geometry of the given VisualEdge object to the coordinate system of the given VisualGraphView object.

Parameters:

vgv - the VisualGraphView object to adjust the geometry of the given VisualEdge object to

ve - the VisualEdge object to adjust the geometry for

VisualGraphView, VisualEdge

applyLayout

public static final void applyLayout(VisualGraphView vgv,
                                     VisualSubgraph vsg)

Applies the layout, the LayoutController associated to the given VisualGraphView object is configured to, to the given VisualSubgraph object.
This means in case the associated LayoutController is configured to perform dynamic layout it is applied to the given VisualSubgraph.
Notice:A dynamic node layout is currently not applied.

Parameters:

vgv - the VisualGraphView object to use the associated LayoutController from

vsg - the VisualSubgraph to apply the layout to
