I have a JTree in a scroll pane.
I want that after every change selection (not only the mouse, but also using the keyboard), the selected node will be seen.
I've added a listener to catch the change selection events and in the event i call to scrollPathToVisible method.
It simply doesn't work.
Can you tell me why?

Hi Rzvika,

I have heard for it :
It's Swing bug, which is reported on Sun web site. There is workaround for it. Just call the function twice :

scrollTreePathToVisible(tree, path);
scrollTreePathToVisible(tree, path);

Best regards,
Valeri

Sorry, call the function twice :

tree.scrollPathToVisible(treePath);
tree.scrollPathToVisible(treePath);

You can use makeVisible(path) as well... What do you exactly want ?
