// NAMING
// please follow these naming rules if you add/change classes:
// the main dialog is named KGameDialog and the base config widget
// KGameDialogConfig. All config widgets are named KGameDialogXYZConfig (where
// XYZ = the name of the config widget, like "general" or "network") and are
// inherited from KGameDialogConfig.

/**
 * TODO: rewrite entire documentation. Nearly nothing is valid anymore.
 * The main configuration dialog for KGame. Here all players meat each other,
 * every player can see how many players connected (and their names) and the
 * ADMIN can even "kick" players out. You can talk to each other (using 
 * KGameChat and the ADMIN can define the maxPlayers/minPlayers as well as the
 * number of computer players.
 *
 *
 * AB: setDefaultXYZ is obsolete!!
 * You will usually create an instance of KGameDialog or any derived class and
 * call setDefaultXYZ methods. Example (maybe
 * obsoleted parameters - docu is currently changing very fast):
 * \code
 * 	KGameDialog dlg(kgame, i18n("New Game"), localPlayer, this, true,
 * 	ID_CHAT);
 * 	dlg.setDefaultNetworkInfo(port, host); // AB: obsolete!
 * 	dlg.exec();
 * \endcode
 * This will create a default modal dialog with the title "New Game". You don't
 * have to do more than this.
