Some JTree properties are closely interrelated. For instance, when the rowHeight property
is positive, it means that the node at each row is displayed with a fixed height, no matter what size
the nodes within the tree should be. When the rowHeight property is negative, the cellRenderer
property determines the rowHeight . So, the value of rowHeight determines the setting of the
