This (IMHO) is the single bigest pain-in-the-... issues with Xforms. In
the end, I gave in and wrote some hideous handlers to manage it, but
because its complex, especially with tabs and multi-line input I seem to
remember, the result requires you to "remember" when adding new call
backs to "do the necessary..". Its all very error prone and has
accounted to two screwups in code I have released.
And thats with using sed to "hack" the fdesign output in the makefile to
replace the input and button create calls with my own (so at least I don't
have to remember to install the prehandler for every one). That generates its
own problems because there are infuriating differences between sed
command line handling between (say) solaris and linux.
All that said I will make 2 positive comments.. ;-)
1. Its impressive that the xforms toolset lets you muck about with it
this much..
2. Because of all the (horibleness of the) handlers, it made doing a
run-time selection of look and feel a real snip and doing so shut up a
lot of people who thought they wanted "gtk" versions of my s/ware when
actually all they wanted was "gtk" look and feel.. ;-)
Cheers
Clive
