Descripción detallada

The QMenuData class is a base class for QMenuBar and QPopupMenu.

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).

The menu item sends out an activated() signal when it is chosen and a highlighted() signal when it receives the user input focus.

menu identifier

Menu items are assigned the menu identifier id that is passed in insertItem() or an automatically generated identifier if id 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.

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().

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().)

The family of insertItem() functions inserts menu items into a popup menu or a menu bar.

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.

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.

The number of insert functions may look confusing, but they are actually quite simple to use.

This default version inserts a menu item with the text text, the accelerator key accel, an id and an optional index and connects it to the slot member in the object receiver.

Example:

        QMenuBar   *mainMenu = new QMenuBar;
        QPopupMenu *fileMenu = new QPopupMenu;
        fileMenu->insertItem( "New",  myView, SLOT(newFile()), CTRL+Key_N );
        fileMenu->insertItem( "Open", myView, SLOT(open()),    CTRL+Key_O );
        mainMenu->insertItem( "File", fileMenu );

Not all insert functions take an object/slot parameter or an accelerator key. Use connectItem() and setAccel() on those items.

If you need to translate accelerators, use tr() with the text and accelerator. (For translations use a string key sequence.):

        fileMenu->insertItem( tr("Open"), myView, SLOT(open()),
                              tr("Ctrl+O") );

In the example above, pressing Ctrl+O or selecting "Open" from the menu activates the myView->open() function.

Some insert functions take a QIconSet parameter to specify the little menu item icon. Note that you can always pass a QPixmap object instead.

The id 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.

The index specifies the position in the menu. The menu item is appended at the end of the list if index is negative.

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.

Atención:: 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. {(QObject*)0}.; 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.

Returns the allocated menu identifier number (id if id >= 0).

Ownership of widget is transferred to the popup menu or to the menu bar.

Theoretically, any widget can be inserted into a popup menu. In practice, this only makes sense with certain widgets.

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.

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 ArrowUp and ArrowDown 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:

        if ( isVisible() &&
             parentWidget() &&
             parentWidget()->inherits("QPopupMenu") )
            parentWidget()->close();

Returns the allocated menu identifier number (id if id >= 0).

Esta es una función miembro sobrecargada que se suministra por conveniencia. Difiere de la anterior función solamente en los argumentos que acepta. Inserts a custom menu item custom with an icon and with optional id id, and optional index position.

This only works with popup menus. It is not supported for menu bars. Ownership of custom is transferred to the popup menu.

If you want to connect a custom item to a slot, use connectItem().

Returns the allocated menu identifier number (id if id >= 0).

int QMenuData::insertSeparator ( int index = -1 )

Inserts a separator at position index, and returns the menu identifier number allocated to it. The separator becomes the last menu item if index is negative.

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).

void QMenuData::setAccel	(	const QKeySequence &	key,
		int	id
	)

void QMenuData::setAccel	(	const QKeySequence &	key,
		int	id
	)

Sets the accelerator key for the menu item id to key.

An accelerator key consists of a key code and a combination of the modifiers SHIFT, CTRL, ALT or UNICODE_ACCEL (OR'ed or added). The header file qnamespace.h contains a list of key codes.

Defining an accelerator key produces a text that is added to the menu item; for instance, CTRL + Key_O produces "Ctrl+O". The text is formatted differently for different platforms.

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.

Example:

        QMenuBar *mainMenu = new QMenuBar;
        QPopupMenu *fileMenu = new QPopupMenu;       // file sub menu
        fileMenu->insertItem( "Open Document", 67 ); // add "Open" item
        fileMenu->setAccel( CTRL + Key_O, 67 );      // Ctrl+O to open
        fileMenu->insertItem( "Quit", 69 );          // add "Quit" item
        fileMenu->setAccel( CTRL + ALT + Key_Delete, 69 ); // add Alt+Del to quit
        mainMenu->insertItem( "File", fileMenu );    // add the file menu

If you need to translate accelerators, use tr() with a string:

        fileMenu->setAccel( tr("Ctrl+O"), 67 );

You can also specify the accelerator in the insertItem() function. You may prefer to use QAction to associate accelerators with menu items.
