96 The QMenuData class is a base class for QMenuBar and QPopupMenu.
97 QMenuData has an internal list of menu items. A menu item can have a
99 text(), an accelerator, a pixmap(), an iconSet(), a whatsThis() text
100 and a popup menu (unless it is a separator). Menu items may optionally
101 be checked (except for separators).
102 The menu item sends out an activated() signal when it is chosen and a
104 highlighted() signal when it receives the user input focus.
105 Menu items are assigned the menu identifier id that is passed in
107 insertItem() or an automatically generated identifier if id is < 0 (the
108 default). The generated identifiers (negative integers) are guaranteed
109 to be unique within the entire application. The identifier is used to
110 access the menu item in other functions.
111 Menu items can be removed with removeItem() and removeItemAt(), or
113 changed with changeItem(). All menu items can be removed with clear().
114 Accelerators can be changed or set with setAccel(). Checkable items can
115 be checked or unchecked with setItemChecked(). Items can be enabled or
116 disabled using setItemEnabled() and connected and disconnected with
117 connectItem() and disconnectItem() respectively. By default, newly
118 created menu items are visible. They can be hidden (and shown again)
119 with setItemVisible().
120 Menu items are stored in a list. Use findItem() to find an item by its
122 list position or by its menu identifier. (See also indexOf() and
123 idAt().)
124 See also QAccel, QPopupMenu, QAction, and Miscellaneous Classes.

291 The family of insertItem() functions inserts menu items into a popup
292 menu or a menu bar.
293 A menu item is usually either a text string or a pixmap, both with an
295 optional icon or keyboard accelerator. For special cases it is also
296 possible to insert custom items (see QCustomMenuItem) or even widgets
297 into popup menus.
298 Some insertItem() members take a popup menu as an additional argument.
300 Use this to insert submenus into existing menus or pulldown menus into
301 a menu bar.
302 The number of insert functions may look confusing, but they are
304 actually quite simple to use.
305 This default version inserts a menu item with the text text, the
307 accelerator key accel, an id and an optional index and connects it to
308 the slot member in the object receiver.
309 Example:
311 QMenuBar *mainMenu = new QMenuBar;
313 QPopupMenu *fileMenu = new QPopupMenu;
314 fileMenu->insertItem( "New", myView, SLOT(newFile()), CTRL+Key_N );
315 fileMenu->insertItem( "Open", myView, SLOT(open()), CTRL+Key_O );
316 mainMenu->insertItem( "File", fileMenu );
317 Not all insert functions take an object/slot parameter or an
319 accelerator key. Use connectItem() and setAccel() on those items.
320 If you need to translate accelerators, use tr() with the text and
322 accelerator. (For translations use a string key sequence.):
323 fileMenu->insertItem( tr("Open"), myView, SLOT(open()),
325 tr("Ctrl+O") );
326 In the example above, pressing Ctrl+O or selecting "Open" from the menu
328 activates the myView->open() function.
329 Some insert functions take a QIconSet parameter to specify the little
331 menu item icon. Note that you can always pass a QPixmap object instead.
332 The id specifies the identification number associated with the menu
334 item. Note that only positive values are valid, as a negative value
335 will make Qt select a unique id for the item.
336 The index specifies the position in the menu. The menu item is appended
338 at the end of the list if index is negative.
339 Note that keyboard accelerators in Qt are not application-global,
341 instead they are bound to a certain top-level window. For example,
342 accelerators in QPopupMenu items only work for menus that are
343 associated with a certain window. This is true for popup menus that
344 live in a menu bar since their accelerators will then be installed in
345 the menu bar itself. This also applies to stand-alone popup menus that
346 have a top-level widget in their parentWidget() chain. The menu will
347 then install its accelerator object on that top-level widget. For all
348 other cases use an independent QAccel object.
349 Warning: Be careful when passing a literal 0 to insertItem() because
351 some C++ compilers choose the wrong overloaded function. Cast the 0 to
352 what you mean, e.g. (QObject*)0.
353 Warning: On Mac OS X, items that connect to a slot that are inserted
355 into a menubar will not function as we use the native menubar that
356 knows nothing about signals or slots. Instead insert the items into a
357 popup menu and insert the popup menu into the menubar. This may be
358 fixed in a future Qt version.
359 Returns the allocated menu identifier number (id if id >= 0).

538
540 This is an overloaded member function, provided for convenience. It
541 behaves essentially like the above function.
542 Inserts a menu item that consists of the widget widget with optional id
544 id, and optional index position.
545 Ownership of widget is transferred to the popup menu or to the menu
547 bar.
548 Theoretically, any widget can be inserted into a popup menu. In
550 practice, this only makes sense with certain widgets.
551 If a widget is not focus-enabled (see QWidget::isFocusEnabled()), the
553 menu treats it as a separator; this means that the item is not
554 selectable and will never get focus. In this way you can, for example,
555 simply insert a QLabel if you need a popup menu with a title.
556 If the widget is focus-enabled it will get focus when the user
558 traverses the popup menu with the arrow keys. If the widget does not
559 accept ArrowUp and ArrowDown in its key event handler, the focus will
560 move back to the menu when the respective arrow key is hit one more
561 time. This works with a QLineEdit, for example. If the widget accepts
562 the arrow key itself, it must also provide the possibility to put the
563 focus back on the menu again by calling QWidget::focusNextPrevChild().
564 Futhermore, if the embedded widget closes the menu when the user made a
565 selection, this can be done safely by calling:
566 if ( isVisible() &&
568 parentWidget() &&
569 parentWidget()->inherits("QPopupMenu") )
570 parentWidget()->close();
571 Returns the allocated menu identifier number (id if id >= 0).
573 See also removeItem().
575
577 int id = -1, int index = -1 )
578 This is an overloaded member function, provided for convenience. It
579 behaves essentially like the above function.
580 Inserts a custom menu item custom with an icon and with optional id id,
582 and optional index position.
583 This only works with popup menus. It is not supported for menu bars.
585 Ownership of custom is transferred to the popup menu.
586 If you want to connect a custom item to a slot, use connectItem().
588 Returns the allocated menu identifier number (id if id >= 0).
590 See also connectItem(), removeItem(), and QCustomMenuItem.
592
594 -1 )
595 This is an overloaded member function, provided for convenience. It
596 behaves essentially like the above function.
597 Inserts a custom menu item custom with optional id id, and optional
599 index position.
600 This only works with popup menus. It is not supported for menu bars.
602 Ownership of custom is transferred to the popup menu.
603 If you want to connect a custom item to a slot, use connectItem().
605 Returns the allocated menu identifier number (id if id >= 0).
607 See also connectItem(), removeItem(), and QCustomMenuItem.
609
611 Inserts a separator at position index, and returns the menu identifier
612 number allocated to it. The separator becomes the last menu item if
613 index is negative.
614 In a popup menu a separator is rendered as a horizontal line. In a
616 Motif menu bar a separator is spacing, so the rest of the items
617 (normally just "Help") are drawn right-justified. In a Windows menu bar
618 separators are ignored (to comply with the Windows style guidelines).
619 Examples:
621
623 Returns TRUE if the menu item with the id id is currently active;
624 otherwise returns FALSE.
625
627 Returns TRUE if the menu item with the id id has been checked;
628 otherwise returns FALSE.
629 See also setItemChecked().
631 Examples:
633
635 Returns TRUE if the item with identifier id is enabled; otherwise
636 returns FALSE
637 See also setItemEnabled() and isItemVisible().
639
641 Returns TRUE if the menu item with the id id is visible; otherwise
642 returns FALSE.
643 See also setItemVisible().
645
647 Returns the parameter of the activation signal of item id.
648 If no parameter has been specified for this item with
650 setItemParameter(), the value defaults to id.

673
675 Returns the pixmap that has been set for menu item id, or 0 if no
676 pixmap has been set.
677 See also changeItem(), text(), and iconSet().
679
681 Removes the menu item that has the identifier id.
682 See also removeItemAt() and clear().
684 Example: chart/chartform.cpp.
686
688 Removes the menu item at position index.
689 See also removeItem() and clear().
691
693 Sets the accelerator key for the menu item id to key.
694 An accelerator key consists of a key code and a combination of the
696 modifiers SHIFT, CTRL, ALT or UNICODE_ACCEL (OR'ed or added). The
697 header file qnamespace.h contains a list of key codes.
698 Defining an accelerator key produces a text that is added to the menu
700 item; for instance, CTRL + Key_O produces "Ctrl+O". The text is
701 formatted differently for different platforms.
702 Note that keyboard accelerators in Qt are not application-global,
704 instead they are bound to a certain top-level window. For example,
705 accelerators in QPopupMenu items only work for menus that are
706 associated with a certain window. This is true for popup menus that
707 live in a menu bar since their accelerators will then be installed in
708 the menu bar itself. This also applies to stand-alone popup menus that
709 have a top-level widget in their parentWidget() chain. The menu will
710 then install its accelerator object on that top-level widget. For all
711 other cases use an independent QAccel object.
712 Example:
714 QMenuBar *mainMenu = new QMenuBar;
716 QPopupMenu *fileMenu = new QPopupMenu; // file sub menu
717 fileMenu->insertItem( "Open Document", 67 ); // add "Open" item
718 fileMenu->setAccel( CTRL + Key_O, 67 ); // Ctrl+O to open
719 fileMenu->insertItem( "Quit", 69 ); // add "Quit" item
720 fileMenu->setAccel( CTRL + ALT + Key_Delete, 69 ); // add Alt+Del to quit
721 mainMenu->insertItem( "File", fileMenu ); // add the file menu
722 If you need to translate accelerators, use tr() with a string:
724 fileMenu->setAccel( tr("Ctrl+O"), 67 );
726 You can also specify the accelerator in the insertItem() function. You
728 may prefer to use QAction to associate accelerators with menu items.
729 See also accel(), insertItem(), QAccel, and QAction.
731 Example: menu/menu.cpp.
733
735 Sets the menu identifier of the item at index to id.
736 If index is out of range, the operation is ignored.
738 See also idAt().
740
742 If check is TRUE, checks the menu item with id id; otherwise unchecks
743 the menu item with id id. Calls QPopupMenu::setCheckable( TRUE ) if
744 necessary.
745 See also isItemChecked().
747 Examples:
749
751 If enable is TRUE, enables the menu item with identifier id; otherwise
752 disables the menu item with identifier id.
753 See also isItemEnabled().
755 Examples:
757
759 Sets the parameter of the activation signal of item id to param.
760 If any receiver takes an integer parameter, this value is passed.
762 See also connectItem(), disconnectItem(), and itemParameter().
764 Example: mdi/application.cpp.
766
768 If visible is TRUE, shows the menu item with id id; otherwise hides the
769 menu item with id id.
770 See also isItemVisible() and isItemEnabled().
772
774 Sets text as What's This help for the menu item with identifier id.
775 See also whatsThis().
777 Examples:
779
781 Returns the text that has been set for menu item id, or QString::null
782 if no text has been set.
783 See also changeItem(), pixmap(), and iconSet().
785 Examples:
787
789 Virtual function; notifies subclasses about an item with id that has
790 been changed.
791 Reimplemented in QPopupMenu.
793
795 Returns the What's This help text for the item with identifier id or
796 QString::null if no text has yet been defined.
797 See also setWhatsThis().
