/**
 * @short Dialog for configuration of KActionCollection and KGlobalAccel.
 *
 * The KShortcutsDialog class is used for configuring dictionaries of key/action
 * associations for KActionCollection and KGlobalAccel. It uses the KShortcutsEditor widget
 * and offers buttons to set all keys to defaults and invoke on-line help.
 *
 * Several static methods are supplied which provide the most convenient interface
 * to the dialog. The most common and most encouraged use is with KActionCollection.
 *
 * \code
 * KShortcutsDialog::configure( actionCollection() );
 * \endcode
 *
 * @since 4.3
 * By default this dialog is modal. If you don't want that, setModal(false) and then the non-static
 * configure() will show the dialog. If you want to do anything extra when the dialog is done,
 * connect to okClicked() and/or cancelClicked(). However, if your extra stuff depends on the
 * changed settings already being saved, connect to saved() instead to be safe; if you connect to
 * okClicked() your function might be called before the save happens.
 *
 * example:
 * \code
 * KShortcutsDialog dlg;
 * dlg.addCollection(myActions);
 * dlg.setModal(false);
 * connect(&dlg, SIGNAL(saved()), this, SLOT(doExtraStuff()));
 * dlg.configure();
 * \endcode
