🚀 go-pugleaf

Torsten,

Meanwhile I found a solution to my problem. In order to have the scrollpane
scrolled so that all childs of a node become visible when expanded, I have
set the following two parameters:

    objTree.setExpandsSelectedPaths(true);
    objTree.setToggleClickCount(1);

where objTree is a JTree component.

I still do not understand, why objTree.setScrollsOnExpand(true) would not
work as well, to get the anticipated behaviour.

Thanks for the help.

Regards

Thomas
