+.SH DESCRIPTION
+The QMenuData class is a base class for QMenuBar and QPopupMenu.
+.PP
+QMenuData has an internal list of menu items. A menu item can have a text(), an accelerator, a pixmap(), an iconSet(), a whatsThis() text and a popup menu (unless it is a separator). Menu items may optionally be checked (except for separators).
+.PP
+The menu item sends out an activated() signal when it is chosen and a highlighted() signal when it receives the user input focus.
+.PP
+
+.PP
+Menu items are assigned the menu identifier \fIid\fR that is passed in insertItem() or an automatically generated identifier if \fIid\fR is < 0 (the default). The generated identifiers (negative integers) are guaranteed to be unique within the entire application. The identifier is used to access the menu item in other functions.
+.PP
+Menu items can be removed with removeItem() and removeItemAt(), or changed with changeItem(). All menu items can be removed with clear(). Accelerators can be changed or set with setAccel(). Checkable items can be checked or unchecked with setItemChecked(). Items can be enabled or disabled using setItemEnabled() and connected and disconnected with connectItem() and disconnectItem() respectively. By default, newly created menu items are visible. They can be hidden (and shown again) with setItemVisible().
+.PP
+Menu items are stored in a list. Use findItem() to find an item by its list position or by its menu identifier. (See also indexOf() and idAt().)
+.PP
+See also QAccel, QPopupMenu, QAction, and Miscellaneous Classes.
+.SH MEMBER FUNCTION DOCUMENTATION
+.SH "QMenuData::QMenuData ()"
+Constructs an empty menu data list.
+.SH "QMenuData::~QMenuData ()\fC [virtual]\fR"
+Removes all menu items and disconnects any signals that have been connected.
+.SH "QKeySequence QMenuData::accel ( int id ) const"
+Returns the accelerator key that has been defined for the menu item \fIid\fR, or 0 if it has no accelerator key or if there is no such menu item.

+.SH "bool QMenuData::connectItem ( int id, const QObject * receiver, const char * member )"
+Connects the menu item with identifier \fIid\fR to \fIreceiver\fR's \fImember\fR slot or signal.
+.PP
+The receiver's slot (or signal) is activated when the menu item is activated.

+.SH "uint QMenuData::count () const"
+Returns the number of items in the menu.
+.SH "bool QMenuData::disconnectItem ( int id, const QObject * receiver, const char * member )"
+Disconnects the \fIreceiver\fR's \fImember\fR from the menu item with identifier \fIid\fR.
+.PP
+All connections are removed when the menu data object is destroyed.
+.PP
+See also connectItem() and setItemParameter().
+.SH "QMenuItem * QMenuData::findItem ( int id ) const"
+Returns the menu item with identifier \fIid\fR, or 0 if there is no item with this identifier.
+.PP
+Note that QMenuItem is an internal class, and that you should not need to call this function. Use the higher level functions like text(), pixmap() and changeItem() to get and modify menu item attributes instead.
+.PP
+See also indexOf().
+.PP
+Example: chart/chartform.cpp.
+.SH "QMenuItem * QMenuData::findItem ( int id, QMenuData ** parent ) const"
+This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
+.PP
+Returns the menu item with identifier \fIid\fR, or 0 if there is no item with this identifier. Changes \fI*parent\fR to point to the parent of the return value.
+.PP
+Note that QMenuItem is an internal class, and that you should not need to call this function. Use the higher level functions like text(), pixmap() and changeItem() to get and modify menu item attributes instead.
+.PP
+See also indexOf().
+.SH "QIconSet * QMenuData::iconSet ( int id ) const"
+Returns the icon set that has been set for menu item \fIid\fR, or 0 if no icon set has been set.
+.PP
+See also changeItem(), text(), and pixmap().
+.SH "int QMenuData::idAt ( int index ) const"
+Returns the identifier of the menu item at position \fIindex\fR in the internal list, or -1 if \fIindex\fR is out of range.
+.PP
+See also setId() and indexOf().
+.SH "int QMenuData::indexOf ( int id ) const"
+Returns the index of the menu item with identifier \fIid\fR, or -1 if there is no item with this identifier.
+.PP
+See also idAt() and findItem().
+.PP
+Example: scrollview/scrollview.cpp.
+.SH "int QMenuData::insertItem ( const QString & text, const QObject * receiver, const char * member, const QKeySequence & accel = 0, int id = -1, int index = -1 )"
+The family of insertItem() functions inserts menu items into a popup menu or a menu bar.
+.PP
+A menu item is usually either a text string or a pixmap, both with an optional icon or keyboard accelerator. For special cases it is also possible to insert custom items (see QCustomMenuItem) or even widgets into popup menus.
+.PP
+Some insertItem() members take a popup menu as an additional argument. Use this to insert submenus into existing menus or pulldown menus into a menu bar.
+.PP
+The number of insert functions may look confusing, but they are actually quite simple to use.
+.PP
+This default version inserts a menu item with the text \fItext\fR, the accelerator key \fIaccel\fR, an id and an optional index and connects it to the slot \fImember\fR in the object \fIreceiver\fR.
+.PP
+Example:
+.PP
+.nf
+.br
+        QMenuBar   *mainMenu = new QMenuBar;
+.br
+        QPopupMenu *fileMenu = new QPopupMenu;
+.br
+        fileMenu->insertItem( "New",  myView, SLOT(newFile()), CTRL+Key_N );
+.br
+        fileMenu->insertItem( "Open", myView, SLOT(open()),    CTRL+Key_O );
+.br
+        mainMenu->insertItem( "File", fileMenu );
+.br
+.fi
+.PP
+Not all insert functions take an object/slot parameter or an accelerator key. Use connectItem() and setAccel() on those items.
+.PP
+If you need to translate accelerators, use tr() with the text and accelerator. (For translations use a string key sequence.):
+.PP
+.nf
+.br
+        fileMenu->insertItem( tr("Open"), myView, SLOT(open()),
+.br
+                              tr("Ctrl+O") );
+.br
+.fi
+.PP
+In the example above, pressing Ctrl+O or selecting "Open" from the menu activates the myView->open() function.
+.PP
+Some insert functions take a QIconSet parameter to specify the little menu item icon. Note that you can always pass a QPixmap object instead.
+.PP
+The \fIid\fR specifies the identification number associated with the menu item. Note that only positive values are valid, as a negative value will make Qt select a unique id for the item.
+.PP
+The \fIindex\fR specifies the position in the menu. The menu item is appended at the end of the list if \fIindex\fR is negative.
+.PP
+Note that keyboard accelerators in Qt are not application-global, instead they are bound to a certain top-level window. For example, accelerators in QPopupMenu items only work for menus that are associated with a certain window. This is true for popup menus that live in a menu bar since their accelerators will then be installed in the menu bar itself. This also applies to stand-alone popup menus that have a top-level widget in their parentWidget() chain. The menu will then install its accelerator object on that top-level widget. For all other cases use an independent QAccel object.
+.PP
+\fBWarning:\fR Be careful when passing a literal 0 to insertItem() because some C++ compilers choose the wrong overloaded function. Cast the 0 to what you mean, e.g. \fC(QObject*)0\fR.
+.PP
+\fBWarning:\fR On Mac OS X, items that connect to a slot that are inserted into a menubar will not function as we use the native menubar that knows nothing about signals or slots. Instead insert the items into a popup menu and insert the popup menu into the menubar. This may be fixed in a future Qt version.
+.PP

+If a widget is not focus-enabled (see QWidget::isFocusEnabled()), the menu treats it as a separator; this means that the item is not selectable and will never get focus. In this way you can, for example, simply insert a QLabel if you need a popup menu with a title.
+.PP
+If the widget is focus-enabled it will get focus when the user traverses the popup menu with the arrow keys. If the widget does not accept \fCArrowUp\fR and \fCArrowDown\fR in its key event handler, the focus will move back to the menu when the respective arrow key is hit one more time. This works with a QLineEdit, for example. If the widget accepts the arrow key itself, it must also provide the possibility to put the focus back on the menu again by calling QWidget::focusNextPrevChild(). Futhermore, if the embedded widget closes the menu when the user made a selection, this can be done safely by calling:
+.PP
+.nf
+.br
+        if ( isVisible() &&
+.br
+             parentWidget() &&
+.br
+             parentWidget()->inherits("QPopupMenu") )
+.br
+            parentWidget()->close();

+.SH "int QMenuData::insertItem ( const QIconSet & icon, QCustomMenuItem * custom, int id = -1, int index = -1 )"
+This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
+.PP
+Inserts a custom menu item \fIcustom\fR with an \fIicon\fR and with optional id \fIid\fR, and optional \fIindex\fR position.
+.PP
+This only works with popup menus. It is not supported for menu bars. Ownership of \fIcustom\fR is transferred to the popup menu.
+.PP
+If you want to connect a custom item to a slot, use connectItem().

+.SH "int QMenuData::insertSeparator ( int index = -1 )"
+Inserts a separator at position \fIindex\fR, and returns the menu identifier number allocated to it. The separator becomes the last menu item if \fIindex\fR is negative.
+.PP
+In a popup menu a separator is rendered as a horizontal line. In a Motif menu bar a separator is spacing, so the rest of the items (normally just "Help") are drawn right-justified. In a Windows menu bar separators are ignored (to comply with the Windows style guidelines).

+.SH "void QMenuData::menuContentsChanged ()\fC [virtual protected]\fR"
+Virtual function; notifies subclasses that one or more items have been inserted or removed.
+.PP
+Reimplemented in QMenuBar.
+.SH "void QMenuData::menuDelPopup ( QPopupMenu * )\fC [virtual protected]\fR"
+Virtual function; notifies subclasses that a popup menu item has been removed.
+.SH "void QMenuData::menuInsPopup ( QPopupMenu * )\fC [virtual protected]\fR"
+Virtual function; notifies subclasses that a popup menu item has been inserted.
+.SH "void QMenuData::menuStateChanged ()\fC [virtual protected]\fR"
+Virtual function; notifies subclasses that one or more items have changed state (enabled/disabled or checked/unchecked).

+.SH "QPixmap * QMenuData::pixmap ( int id ) const"
+Returns the pixmap that has been set for menu item \fIid\fR, or 0 if no pixmap has been set.
+.PP
+See also changeItem(), text(), and iconSet().
+.SH "void QMenuData::removeItem ( int id )"
+Removes the menu item that has the identifier \fIid\fR.
+.PP
+See also removeItemAt() and clear().
+.PP
+Example: chart/chartform.cpp.
+.SH "void QMenuData::removeItemAt ( int index )"
+Removes the menu item at position \fIindex\fR.
+.PP
+See also removeItem() and clear().
+.SH "void QMenuData::setAccel ( const QKeySequence & key, int id )"
+Sets the accelerator key for the menu item \fIid\fR to \fIkey\fR.
+.PP
+An accelerator key consists of a key code and a combination of the modifiers \fCSHIFT\fR, \fCCTRL\fR, \fCALT\fR or \fCUNICODE_ACCEL\fR (OR'ed or added). The header file ntqnamespace.h contains a list of key codes.
+.PP
+Defining an accelerator key produces a text that is added to the menu item; for instance, \fCCTRL\fR + \fCKey_O\fR produces "Ctrl+O". The text is formatted differently for different platforms.
+.PP
+Note that keyboard accelerators in Qt are not application-global, instead they are bound to a certain top-level window. For example, accelerators in QPopupMenu items only work for menus that are associated with a certain window. This is true for popup menus that live in a menu bar since their accelerators will then be installed in the menu bar itself. This also applies to stand-alone popup menus that have a top-level widget in their parentWidget() chain. The menu will then install its accelerator object on that top-level widget. For all other cases use an independent QAccel object.
+.PP
+Example:
+.PP
+.nf
+.br
+        QMenuBar *mainMenu = new QMenuBar;
+.br
+        QPopupMenu *fileMenu = new QPopupMenu;       // file sub menu
+.br
+        fileMenu->insertItem( "Open Document", 67 ); // add "Open" item
+.br
+        fileMenu->setAccel( CTRL + Key_O, 67 );      // Ctrl+O to open
+.br
+        fileMenu->insertItem( "Quit", 69 );          // add "Quit" item
+.br
+        fileMenu->setAccel( CTRL + ALT + Key_Delete, 69 ); // add Alt+Del to quit
+.br
+        mainMenu->insertItem( "File", fileMenu );    // add the file menu
+.br
+.fi
+.PP
+If you need to translate accelerators, use tr() with a string:
+.PP
+.nf
+.br
+        fileMenu->setAccel( tr("Ctrl+O"), 67 );
+.br
+.fi
+.PP
+You can also specify the accelerator in the insertItem() function. You may prefer to use QAction to associate accelerators with menu items.
+.PP
+See also accel(), insertItem(), QAccel, and QAction.

+Example: menu/menu.cpp.
+.SH "void QMenuData::setId ( int index, int id )\fC [virtual]\fR"
