term is a terminal widget with configurable 3D pseudographic symbols and configurable attributes. For example, the attribute bold you can assign a 3D-background color and a relief (comparable with Tun Terminal Emulation). term was used to implement a full-featured xterm Emulation in tcl, which is part of 4GL Server . In the middle of the year we will introduce it for the tcl-community as a TK8.0-extension, but until now it's WTK -specific and only as native Windows widget available.
