The idea about the "suspect" widgets is for the button controller to have an
addSuspect method. I'd invoke it within the View's build method:
bc().addSuspect(&widgets().someSuspectWidget);
Then when bc.valid() gets called, it could loop over this list of widgets
list<XFwidget *> suspect;
list<XFwidget *>::const_iterator it = suspect.begin();
list<XFwidget *>::const_iterator end = suspect.end();
bool valid = true;
for (; it != end; ++it) {
if (!isValid(*it))
valid = false;
}
if (valid)
// enable Apply/Ok
So, if you don't want this, then don't invoke addSuspect!
I'd like to see what you come up with instead in QPreferences though...
