Jtree with setRootVisible
Hello,
I have a tree, now if I use setRootVisible(false) to hide the root, and I want if the direct child of this root (level 1) has the childrens (leve 2), the sign (+) will be display before the child level 1. I run some JTree example, but the (+) sign not displayed...
How can I do?
Thank you

may this is because of your operating system (if windows then windxp ) problem.

Infact, I don't know that it isn't satify you because I just made a comment "good answer" :) Sorry, I will do another time for an excellent answer :)
Well, I interpret a "good answer" (or B-grade) as: it's OK, but it could have been better/more specific.
Since it was exactly what you needed, I thought it deserved an A-grade.

Set whether the tree shows handles for its leftmost nodes, letting you expand and collapse the nodes.
The default is false. If the tree doesn't show the root node, then you should invoke setShowsRootHandles(true).
