To subscribers of the xforms list from Matthew Wilburn <mattw@nbstech.com> :


I am also experiencing problems while working through
the example by Jacques Tremblay.

Please be patient I have little experience with either c++ or XForms.

Heres the problem:

MYClass::MYClass() : FormApp() {
fd_MYform =3D create_form_MYform();
fl_set_object_label(fd_MYform->okbutton, "hello");

The fl_set_object_label call here works just fine.

MYClass::MYfunc() {
fl_set_object_label(fd_MYform->okbutton, "bye");

but here I get an SIGSEGV fault.
XXGDB reports that fd_MYform in MYfunc is (FD_MYform *),
but I am unable to inspect fd_MYform->okbutton->label without getting inacc=
essable memory at some location.

What am I doing wrong?
