    44     \title Platform-Specific Functions
       
    45     \ingroup funclists
       
    46 
       
    47     \brief Exported functions for fine tuning Qt applications.
       
    48 
       
    49     Qt provides a few low-level global functions for fine-tuning
       
    50     applications. Most of these perform very specific tasks and are
       
    51     platform-specific. In general, we recommend that you try using
       
    52     Qt's public API before resorting to using any functions mentioned
       
    53     here.
       
    54 
       
    55     These functions are exported by \l QtCore and \l QtGui, but most
       
    56     of them aren't declared in Qt's header files. To use them in your
       
    57     application, you must declare them before calling them. For
       
    58     example:
       
    59 
       
    60     \snippet doc/src/snippets/code/doc_src_exportedfunctions.qdoc 0
       
    61 
       
    62     These functions will remain as part of Qt for the lifetime of Qt
       
    63     4.
       
    64 
       
    65     Functions:
       
    66 
       
    67     \tableofcontents
       
    68 
       
    69     \section1 void qt_set_library_config_file(const QString &\e{fileName})
       
    70 
       
    71     Specifies the location of the Qt configuration file. You must
       
    72     call this function before constructing a QApplication or
       
    73     QCoreApplication object. If no location is specified, Qt
       
    74     automatically finds an appropriate location.
       
    75 
       
    76     \section1 void qt_set_sequence_auto_mnemonic(bool \e{enable})
       
    77 
       
    78     Specifies whether mnemonics for menu items, labels, etc., should
       
    79     be honored or not. On Windows and X11, this feature is
       
    80     on by default; on Mac OS X, it is off. When this feature is off,
       
    81     the QKeySequence::mnemonic() function always returns an empty
       
    82     string. This feature is also enabled on embedded Linux.
       
    83 
       
    84     \section1 void qt_x11_wait_for_window_manager(QWidget *\e{widget})
       
    85 
       
    86     Blocks until the X11 window manager has shown the widget after a
       
    87     call to QWidget::show().
       
    88 
       
    89     \section1 void qt_mac_secure_keyboard(bool \e{enable})
       
    90 
       
    91     Turns the Mac OS X secure keyboard feature on or off. QLineEdit
       
    92     uses this when the echo mode is QLineEdit::Password or
       
    93     QLineEdit::NoEcho to guard the editor against keyboard sniffing.
       
    94     If you implement your own password editor, you might want to turn
       
    95     on this feature in your editor's
       
    96     \l{QWidget::focusInEvent()}{focusInEvent()} and turn it off in
       
    97     \l{QWidget::focusOutEvent()}{focusOutEvent()}.
       
    98 
       
    99     \section1 void qt_mac_set_dock_menu(QMenu *\e{menu})
       
   100 
       
   101     Sets the menu to display in the Mac OS X Dock for the
       
   102     application. This menu is shown when the user attempts a
       
   103     press-and-hold operation on the application's dock icon or
       
   104     \key{Ctrl}-clicks on it while the application is running.
       
   105 
       
   106     The menu will be turned into a Mac menu and the items added to the default
       
   107     Dock menu. There is no merging of the Qt menu items with the items that are
       
   108     in the Dock menu (i.e., it is not recommended to include actions that
       
   109     duplicate functionality of items already in the Dock menu).
       
   110 
       
   111     \section1 void qt_mac_set_menubar_icons(bool \e{enable})
       
   112 
       
   113     Specifies whether icons associated to menu items for the
       
   114     application's menu bar should be shown on Mac OS X. By default,
       
   115     icons are shown on Mac OS X just like on the other platforms.
       
   116 
       
   117     In Qt 4.4, this is equivalent to
       
   118     \c { QApplication::instance()->setAttribute(Qt::AA_DontShowIconsInMenus); }.
       
   119 
       
   120     \section1 void qt_mac_set_menubar_merge(bool \e{enable})
       
   121 
       
   122     Specifies whether Qt should attempt to relocate standard menu
       
   123     items (such as \gui Quit, \gui Preferences, and \gui About) to
       
   124     the application menu on Mac OS X. This feature is on by default.
       
   125     See \l{Qt for Mac OS X - Specific Issues} for the list of menu items for
       
   126     which this applies.
       
   127 
       
   128     \section1 void qt_mac_set_native_menubar(bool \e{enable})
       
   129 
       
   130     Specifies whether the application should use the native menu bar
       
   131     on Mac OS X or be part of the main window. This feature is on by
       
   132     default.
       
   133 
       
   134     In Qt 4.6, this is equivalent to
       
   135     \c { QApplication::instance()->setAttribute(Qt::AA_DontUseNativeMenuBar); }.
       
   136 
       
   137     \section1 void qt_mac_set_press_and_hold_context(bool \e{enable})
       
   138 
       
   139     Turns emulation of the right mouse button by clicking and holding
       
   140     the left mouse button on or off. This feature is off by default.
