Optional absoluteDefaults to false. If true, then the layout will use any position values found in the data for a given vertex.
Optional getOptional function used to determine the edges to traverse to find children from some node
Optional getOptional. A function that is given the Toolkit instance as argument and is expected to return either a single node/group, or an array of nodes/groups, to use as the root(s) for the layout
Optional groupMinimum distance between a group of vertices and its neighbours. Defaults to 100 pixels.
Optional heightOptional fixed height for the layout.
Optional ignoreDefaults to true. If a loop is found during the layout it is usually ignored, unless this is set to true.
Optional ignoreDefaults to false, meaning that ports are taken into account when figuring the list of edges from some vertex. If you set
this to true, ports will be ignored and the layout will only consider edges connected directly to each vertex.
Optional locationOptional function that, given some vertex, can provide the x/y location of the vertex on the canvas
Optional multipleOptional, defaults to true. If false, multiple roots are not supported, and assuming you have not overridden getRootNode, the layout uses the first node found in the dataset (otherwise it still uses the result of your getRootNode function)
Optional paddingOptional padding to put around the elements.
Optional rootOptional. Defines the node/group to use as the root of the tree. This may be provided either as a node/group id or as a node/group object. If this parameter is not specified and multipleRoots is not false then the layout uses the result(s) of the getRootNode function; otherwise it uses the first node/group found in the dataset.
Optional widthOptional fixed width for the layout.
Constructor parameters for a Balloon layout.
