Is there a way to hide the collapse [-] and expand [+] button on a java file JTree?
If it's not possible, is there a way to change it to a different icon?

推荐答案

两者都可以:您可以指定一个空的Icon，如图所示此处所示.这些是相关的UIManager键:

Yes to both: You can specify an empty Icon, as shown here. You can substitute your own implementation, as shown here. These are the relevant UIManager keys:

UIManager.put("Tree.collapsedIcon", empty);
UIManager.put("Tree.expandedIcon", empty);
