Here is the code I ended up with. Seems to work:

bool MyApplet::isOpen() const {
    if (formFactor() == Plasma::Horizontal || formFactor() ==
Plasma::Vertical) {
        return isPopupShowing();
    } else {
        return true;
    }
}

Any chance of getting this (or something like it) added to the
PopupApplet API? Seems generally useful, since it gives applets an
opportunity to reduce their resource footprint when they're not
displayed.
