public void setDecoree(TreeModel model)

Overrides:

setDecoree in class TreeModelDecorator

isBounded

public boolean isBounded(java.lang.Object parent)

Description copied from interface: TreeBounding

if true, instead of (+) or (-) a refresh symbol (o) is displayed to allow the user to refresh the children of the parent node.

Specified by:

isBounded in interface TreeBounding

unbound
