Class RadialLayoutAlgorithm

java.lang.Object
org.eclipse.zest.layouts.algorithms.AbstractLayoutAlgorithm
org.eclipse.zest.layouts.algorithms.RadialLayoutAlgorithm
All Implemented Interfaces:
LayoutAlgorithm

public class RadialLayoutAlgorithm extends AbstractLayoutAlgorithm
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.

      @Deprecated public RadialLayoutAlgorithm(int style)
      Deprecated.
      Since Zest 2.0, use RadialLayoutAlgorithm().

  • Method Details

    • applyLayout

      public void applyLayout(boolean clean)
      Description copied from interface: LayoutAlgorithm
      Makes this algorithm perform layout computation and apply it to its context.
      Parameters:
      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.
    • setLayoutContext

      public void setLayoutContext(LayoutContext context)
      Description copied from interface: LayoutAlgorithm
      Sets the layout context for this algorithm. The receiver will unregister from its previous layout context and register to the new one (registration means for example adding listeners). After a call to this method, the receiving algorithm can compute and cache internal data related to given context and perform an initial layout.
      Specified by:
      setLayoutContext in interface LayoutAlgorithm
      Overrides:
      setLayoutContext in class AbstractLayoutAlgorithm
      Parameters:
      context - a new layout context or null if this algorithm should not perform any layout
    • setRangeToLayout

      public void setRangeToLayout(double startDegree, double endDegree)
      Set the range the radial layout will use when applyLayout is called. Both values must be in radians.
    • isResizing

      public boolean isResizing()
      Returns:
      true if this algorithm is set to resize elements
      Since:
      2.0
    • setResizing

      public void setResizing(boolean resizing)
      Parameters:
      resizing - true if this algorithm should resize elements (default is false)
      Since:
      2.0
