- public class MetalTreeUI
- extends BasicTreeUI
MetalTreeUI supports the client property "value-add" system of customization
It uses it to determine what style of line to draw. There are three choices.
The default choice is to draw no lines.
Also available is a more variant with angled legs running from parent to child.
Lastly you can choose an option with horizonl lines be lines at all.
Here is some code to turn on angled legs.
tree.putClientProperty("JTree.lineStyle", "Angled");
Here is some code to turn on horizontal lines between root nodes.
tree.putClientProperty("JTree.lineStyle", "Horizontal");
Here is some code to turn off lines all together (which is the default).
tree.putClientProperty("JTree.lineStyle", "None");
