Class RadialLayoutAlgorithm

java.lang.Object
org.eclipse.gef.layout.algorithms.RadialLayoutAlgorithm
All Implemented Interfaces:
ILayoutAlgorithm

public class RadialLayoutAlgorithm extends Object implements ILayoutAlgorithm
This layout will take the given entities, apply a tree layout to them, and then display the tree in a circular fashion with the roots in the center.

  • Method Details

    • applyLayout

      public void applyLayout(LayoutContext layoutContext, boolean clean)
      Description copied from interface: ILayoutAlgorithm
      Makes this algorithm perform layout computation and apply it to its context.
      Specified by:
      applyLayout in interface ILayoutAlgorithm
      Parameters:
      layoutContext - The LayoutContext that provides all relevant information about what to layout.
      clean - if true the receiver should assume that the layout context has changed significantly and recompute the whole layout even if it keeps track of changes with listeners. False can be used after dynamic layout in a context is turned back on so that layout algorithm working in background can apply accumulated changes. Static layout algorithm can ignore this call entirely if clean is false.
    • setRangeToLayout

      public void setRangeToLayout(double startDegree, double endDegree)
      Set the range the radial layout will use when applyLayout(LayoutContext, boolean) is called. Both values must be in radians.
      Parameters:
      startDegree - The start angle for this algorithm (in degree).
      endDegree - The end angle for this algorithm (in degree).
    • isResizing

      public boolean isResizing()
      Returns:
      true if this algorithm is set to resize elements
    • setResizing

      public void setResizing(boolean resizing)
      Parameters:
      resizing - true if this algorithm should resize elements (default is false)
