I tried it and it works. But I want to be able to select whether
I want to see the Xforms messages or not, at run time.
What is the name of the xforms internal routine
that whereError() should return if I want the "default"
Xforms error handler to be used ? I tried NULL, but
it does not work.
By the way, the manual mentions a routine called
fl_show_error(). I tried fl_show_error(0), but
it does not seem to prevent messages like:
In MapColor [flcolor.c 807] ColormapFull. Using subsititutions
Is fl_show_error(0) supposed to prevent this type
of messages ? Should fl_show_error(0) be called
before or right after fl_initialize() ?
