tow


Tow's arguments are:  destination window, widget type, and widget id.  All are obligatory.  To see what they mean, read about other classes from toxy collection, widget and tot.

A tow object is automatically attached to all widgets of a specified type and id, which are contained in a destination window.  Anything going into the tow's inlet is forwarded to all attached widgets.  Anything coming out of the outlet of any attached widget is forwarded to the tow's outlet.

There may be many tows attached to the same widget, just as there may be several widgets attached to the same tow.  However, while a group of tows may be scattered over different windows, all widgets of one group always belong to the same window.
