However, if you + * need the help menu or any of its dialog boxes in your code that is + * not subclassed from KMainWindow you should use this class. + * + * The usage is simple: + * + * \code + * mHelpMenu = new KHelpMenu( this, ); + * kmenubar->insertItem(i18n("&Help"), mHelpMenu->menu() ); + * \endcode + * + * or if you just want to open a dialog box: + * + * \code + * mHelpMenu = new KHelpMenu( this, ); + * connect( this, TQT_SIGNAL(someSignal()), mHelpMenu,TQT_SLOT(mHelpMenu->aboutKDE())); + * \endcode + * + * IMPORTANT: + * The first time you use KHelpMenu::menu(), a KPopupMenu object is + * allocated. Only one object is created by the class so if you call + * KHelpMenu::menu() twice or more, the same pointer is returned. The class + * will destroy the popupmenu in the destructor so do not delete this + * pointer yourself. + * + * The KHelpMenu object will be deleted when its parent is destroyed but you + * can delete it yourself if you want. The code below will always work. + * + * \code + * MyClass::~MyClass() + * { + * delete mHelpMenu; + * } + * \endcode + * + * + * Using your own "about application" dialog box: + * + * The standard "about application" dialog box is quite simple. If you + * need a dialog box with more functionality you must design that one + * yourself. When you want to display the dialog you can choose one of + * two methods. Common for both is that you must make a help menu object + * with no text argument If the text is missing the default dialog box + * will not be displayed: + * + * Example 1 Using showAboutApplication signal (preferred) + * \code + * + * void MyClass::myFunc() + * { + * .. + * KHelpMenu *helpMenu = new KHelpMenu( this ); + * connect( helpMenu, TQT_SIGNAL(showAboutApplication()), + * this, TQT_SLOT(myDialogSlot())); + * .. + * } + * + * void MyClass::myDialogSlot() + * { + * + * } + * \endcode + * + * + * Example 2 Old style - connecting directly to the menu entry. + * \code + * + * void MyClass::myFunc() + * { + * KHelpMenu *helpMenu = new KHelpMenu( this ); + * KPopupMenu *help = mHelpMenu->menu(); + * help->connectItem( KHelpMenu::menuAboutApp, this, TQT_SLOT(myDialogSlot()) ); + * } + * + * void MyClass::myDialogSlot() + * { + * + * } + * \endcode + * + * @author Espen Sand (espen@kde.org) + */ + +class KDEUI_EXPORT KHelpMenu : public TQObject +{ + Q_OBJECT + + public: + enum MenuId + { + menuHelpContents = 0, + menuWhatsThis = 1, + menuAboutApp = 2, + menuAboutKDE = 3, + menuReportBug = 4, + menuSwitchLanguage = 5 + }; + + /** + * Constructor. + * + * @param parent The parent of the dialog boxes.
