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");

Method Detail

createUI

public static ComponentUI createUI(JComponent x)

getHorizontalLegBuffer

protected int getHorizontalLegBuffer()
Description copied from class: BasicTreeUI
The horizontal element of legs between nodes starts at the right of the left-hand side of the child node by default. This method makes the leg end before that.
Overrides:
getHorizontalLegBuffer in class BasicTreeUI

installUI

public void installUI(JComponent c)
Overrides:
installUI in class BasicTreeUI

uninstallUI

public void uninstallUI(JComponent c)
Overrides:
uninstallUI in class BasicTreeUI

decodeLineStyle

protected void decodeLineStyle(Object lineStyleFlag)
this function converts between the string passed into the client property and the internal representation (currently and int)

isLocationInExpandControl

protected boolean isLocationInExpandControl(int row,
                                            int rowLevel,
