Yes, it is documented. Either read
BCView.h ButtonController.h ButtonPolicies.h
in frontends/controllers/
or 'make doxydoc' and read the generated html.
Of course, that isn't necessarily useful, so just follow the example of the
XForms frontend:
void GChanges::doBuild()
{
// disable for read-only documents
bcview().addReadOnly(acceptbutton_);
bcview().addReadOnly(rejectbutton_);
bcview().addReadOnly(nextbutton_);
}
Thereafter all you need is:
void GChanges::promptChange()
{
bc().readonly(false);
}
void GChanges::promptDismiss()
{
bc().readonly(true);
}
Ok, I realise that this isn't really a 'readonly' toggle, but if you want
to add a ChangesPolicy, be my guest...
