Detailed Description

Base class for tree items.

Deprecated:: The CEGUI::Tree, CEGUI::TreeItem and any other associated classes are deprecated and thier use should be minimised - preferably eliminated - where possible. It is extremely unfortunate that this widget was ever added to CEGUI since its design and implementation are poor and do not meet established standards for the CEGUI project.

: While no alternative currently exists, a superior, replacement tree widget will be provided prior to the final removal of the current implementation.
