in my application, I've created a JTree.
in this tree there are folders and leaves, but the leaves are all the nodes that has no suns and they are painted as folders.
i want to control on the when it will paint the node as not a folder (even if it doesn't have sons).
how can i do it?

you have to implement your own TreeCellRenderer

you can found such an example with your Swing distribution . (I think it name was TreeDemo or something very similiar ...)

if you have some more concrete problem, post it here
hope this helps

sorry for not answering your answer.
i know that there are ways to draw,put icon etc. in a node.
as you know from the windows, even if there aren't any children in a folder it still looks as a folder and not as a file.
when you create a node, you specify whether it can have children or not.
is there a way that the drawing of the tree will get this information and according to that it will make it looks like a folder or a file?
thank you.

you can modify the look&feel of the tree icons (folders/files) by implementing your own tree cell renderer, and there is such an example in your swing examples subdirectory ...

or you have some other problem ?
