The TCL/GWM image display and plotting widget1 is a alternative Xdisplay manager, to be used in place of the standard GWM Xdisplay manager.
By using TCL to develop the display manager, quite small amounts of code can be used to generate quite powerful systems, and it is relatively easy to extend to provide new features. This version is only a demonstration of what can be achieved. Users may make copies of the relevant code and extend it if they so wish.
Full details on the TCL/GWM widget and the standard GWM Xdisplay manager are give in SUN/186 (STARTCL) and SUN/130 (GWM) respectively.
1A widget is the name given to this type of application in the TCL system. Any resemblance to the widgets found in beer cans is a figment of the imagination.
