java - JTree: TreeCellRenderer not doing as expected -


in nutshell, want tree rendered such first level bold.

public class treerenderer1 extends defaulttreecellrenderer {  @override public component gettreecellrenderercomponent(jtree tree, object value,         boolean sel, boolean exp, boolean leaf, int row, boolean hasfocus) {     super.gettreecellrenderercomponent(tree, value, sel, exp, leaf, row, hasfocus);      defaultmutabletreenode node = (defaultmutabletreenode)value;      if (node.getlevel()==1) {         setfont(getfont().derivefont(font.bold));     }      return this; } }

this, however, make nodes in tree bold. wrong?

reset font state of render if level not 1...

if (node.getlevel()==1) {     setfont(getfont().derivefont(font.bold)); } else {     setfont(getfont().derivefont(font.plain)); }

render's shared resource, changes make carried onto next element rendered, must make sure set "default" state @ point
