Here are a few excerpts from a report I am writing. I thought it would be fun for you to tear them apart: *********************** Toolkits allow for the creation of widgets: windows which wait for user input (mouse button hits only) and then call application-defined routines to respond appropriately. With toolkits, one may not freely draw graphical objects into the widgets or to define colors and layers. To do these things, the application must go outside the toolkit by calling Xlib directly or by defining its own widgets. The definition of widgets is not trivial as it requires the programmer to understand the concepts behind object-oriented programming. Further, toolkits are wedded to a particular graphics library. Their focus is not to provide independence from the "standard" upon which they happen to be built. However, that need not always be the case. While some concepts may work best under X (especially in use of windows), it seems likely that the idea of graphics library independence will work its way forward soon. *********************** Lisa. pickel@mcnc.org
