It would be nice if the text widget in lib/Xaw had a callback list which is called when the source buffer is full. I intend to change the text widget so that the source->replace (i.e. StringReplaceText) returns a BufferFull error code and then have ReplaceText make any callbacks registered, the question is what information does the callback require? As far as I can see the callback really needs the text.source->Replace as well as all the parameters that were passed to it and it has to either guarantee that it has corrected the problem (by removing the first half of the buffer say) or it has to return a flag to indicate whether or not it succeeded in doing something about it. Do the toolkit wizards have any ideas? Thanks, Julian Payne, European Silicon Structures (ES2). (payne@latlog.uucp) P.S. The intrinsics and athena widgets are `fab', let's have more?
