问题
I am trying to make:
A JTree where ALL nodes have the possibility of a JCheckBox.
After having selected the different checkboxes I would like to be able to extract strings stating the node path to the different checked nodes.
The leader node must be able to show if a child node has been selected.
I have included a small SSCCE
