  \class QPopupMenu qpopupmenu.h
  \brief The QPopupMenu class provides a popup menu widget.

  \ingroup application
  \ingroup basic
  \mainclass

  A popup menu widget is a selection menu. It can be either a pull-down
  menu in a menu bar or a standalone context (popup) menu.  Pull-down menus
  are shown by the menu bar when the user clicks on the respective
  item or hits the specified shortcut key. Use QMenuBar::insertItem()
  to insert a popup menu into a menu bar. Show a context menu either
  asynchronously with popup() or synchronously with exec().

  Technically, a popup menu consists of a list of menu items. You add
  items with insertItem().  An item is either a string, a pixmap or a
  custom item that provides its own drawing function (see
  QCustomMenuItem). In addition, items can have an optional icon drawn
  on the very left side and an accelerator key such as "Ctrl+X".  The
  accelerator can also be changed at run-time by holding the left mouse
  button over an item and pressing the new accelerator.

  There are three kinds of menu items: separators, menu items that perform
  an action and menu items that show a submenu.  Separators are inserted
  with insertSeparator(). For submenus, you pass a pointer to a
  QPopupMenu in your call to insertItem().  All other items are
  considered action items.

  When inserting action items you usually specify a receiver and a
  slot. The receiver will be notifed whenever the item is
  selected. In addition, QPopupMenu provides two signals, activated()
  and highlighted(), which signal the identifier of the respective menu
  item. It is sometimes practical to connect several items to one
  slot. To distinguish between them, specify a slot that takes an
  integer argument and use setItemParameter() to associate a unique
  value with each item.

  You clear a popup menu with clear() and remove single items with
  removeItem() or removeItemAt().

  A popup menu can display check marks for certain items when enabled
  with setCheckable(TRUE). You check or uncheck items with
  setItemChecked().

  Items are either enabled or disabled. You toggle their state with
  setItemEnabled().  Just before a popup menu becomes visible, it
  emits the aboutToShow() signal. You can use this signal to set the
  correct enabled/disabled states of all menu items before the user
  sees it. The corresponding aboutToHide() signal is emitted when the
  menu hides again.

  You can provide What's This? help for single menu items with
  setWhatsThis(). See QWhatsThis for general information about this
  kind of lightweight online help.

  For ultimate flexibility, you can also add entire widgets as items
  into a popup menu (for example, a color selector).

  A QPopupMenu can also provide a tear-off menu. A tear-off menu is a
  top-level window that contains a copy of the menu. This makes it
  possible for the user to "tear off" frequently used menus and
  position them in a convenient place on the screen. If you want that
  functionality for a certain menu, insert a tear-off handle with
  insertTearOffHandle(). If you want to include custom widgets in a
  tear-off menu, you should connect to the popup menu's signal (using
  connectItem() and the item ID that insertTearOffHandle() returns),
  and add the custom widgets you want to include. When using tear-off
  menus, bear in mind that the concept isn't typically used on
  Microsoft Windows so users may not be familiar with it. Consider
  using a QToolBar instead.

  menu/menu.cpp is a typical example of QMenuBar and QPopupMenu use.

/*!
    \overload
    Executes this popup synchronously.

  Opens the popup menu so that the item number \a indexAtPoint will be
  at the specified \e global position \a pos.  To translate a widget's
  local coordinates into global coordinates, use QWidget::mapToGlobal().

  The return code is the id of the selected item in either the popup
  menu or one of its submenus, or -1 if no item is selected (normally
  because the user presses Escape).

  Note that all signals are emitted as usual.  If you connect a menu
  item to a slot and call the menu's exec(), you get the result both
  via the signal-slot connection and in the return value of exec().

  Common usage is to position the popup at the current
  mouse position:
  \code
      exec(QCursor::pos());
  \endcode
  or aligned to a widget:
  \code
      exec(somewidget.mapToGlobal(QPoint(0,0)));
  \endcode

  When positioning a popup with exec() or popup(), bear in mind that
  you cannot rely on the popup menu's current size(). For performance
  reasons, the popup adapts its size only when necessary. So in many
  cases, the size before and after the show is different. Instead, use
  sizeHint(). It calculates the proper size depending on the menu's
  current contents.

  Inserts a tear-off handle into the menu. A tear-off handle is a
  special menu item that creates a copy of the menu when the menu is
  selected. This "torn-off" copy lives in a separate window. It
  contains the same menu items as the original menu, with the exception
  of the tear-off handle.

  The handle item is assigned the identifier \a id or an automatically
  generated identifier if \a id is < 0. The generated identifiers
  (negative integers) are guaranteed to be unique within the entire
  application.

  The \a index specifies the position in the menu.  The tear-off
  handle is appended at the end of the list if \a index is negative.
