 * Since the settings on the second Tab Page (Options) effects
 * the first Tab Page, there must be a way for it to communicate with the
 * other Page.
 *
 * At the moment this problem is solved through using two data members of the
 * Tab Pages. If a page is enabled / disabled, it compares this data member
 * with its own state (-> Activate() / Deactivate()).
 *
 * In the meantime the class SfxTabPage offers the following method:
 *
 * virtual sal_Bool HasExchangeSupport() const; -> return sal_True;
 * virtual void ActivatePage(const SfxItemSet &);
 * virtual int  DeactivatePage(SfxItemSet * = 0);
 *
 * This still needs to be changed!
