如何更改 TreeLayout JUNG 中边的长度?

How to change the length of an edge in TreeLayout JUNG?

我知道如何更改顶点的大小,但是当我这样做时,TreeLayout 放置节点时边缘消失,即。节点重叠,边缘不可见。如果我更改布局(到 KKLayout),边缘会自动变大并且图形看起来很干净。我想知道是否可以 space TreeLayout 本身的节点 apart/increase 边的长度? (任何其他维护树层次结构的建议也很好)

您可以在构建 TreeLayout 时定义节点之间的 space。这会增加边长:

TreeLayout treeLayout = new TreeLayout<String, Integer>(graph, 500, 500);

如果您不为 distxdisty 输入值,则默认为 50。构造函数:

/**
 * Creates an instance for the specified graph, X distance, and Y distance.
 */
public TreeLayout(Forest<V,E> g, int distx, int disty) {
    if (g == null)
        throw new IllegalArgumentException("Graph must be non-null");
    if (distx < 1 || disty < 1)
        throw new IllegalArgumentException("X and Y distances must each be positive");
    this.graph = g;
    this.distX = distx;
    this.distY = disty;
    buildTree();
}
