breadthFirstLayout
public boolean breadthFirstLayout(com.macrofocus.geom.Shape shape, MutableTreeMapNode parent, MutableTreeMapNode[] children, double sumSizes, int horizontalVanishingPoint, int verticalVanishingPoint, TreeMapWorker worker) Description copied from interface:Algorithm
Arrange the items in the given array to fill the given shape. This is called during the first pass, while traversing the tree top down.- Parameters:
shape
- the current rectangle being divided.parent
- the parent node.children
- the items to map.sumSizes
- the size of the parent.worker
- the worker thread- Returns:
- true if the layout has been cancelled, false otherwise
-
isCompatible
public boolean isCompatible(com.macrofocus.geom.Shape shape) Description copied from interface:Algorithm
Indicates whether the layout algorithm can handle the given geometry of its parent- Parameters:
shape
- the geometry of its parent- Returns:
- true if it can lay out the children using the specified geometrical shape
