The X11 windows system also defines gadgets and their relationship to widgets (buttons, labels etc.). The gadget was a windowless widget which was supposed to improve the performance of the application by reducing the memory load on the X server. A gadget would use the Window id of its parent widget and had no children of its own. It is not known whether other software companies are explicitly drawing on that inspiration when featuring the word in names of their technologies or simply referring to the generic meaning. The word widget is older in this context.
