Most of these perform very specific tasks and are + platform-specific. In general, we recommend that you try using + Qt's public API before resorting to using any functions mentioned + here. + + These functions are exported by \l QtCore and \l QtGui, but most + of them aren't declared in Qt's header files. To use them in your + application, you must declare them before calling them. For + example: + + \snippet doc/src/snippets/code/doc_src_exportedfunctions.qdoc 0 + + These functions will remain as part of Qt for the lifetime of Qt + 4. + + Functions: + + \tableofcontents + + \section1 void qt_set_library_config_file(const QString &\e{fileName}) + + Specifies the location of the Qt configuration file. You must + call this function before constructing a QApplication or + QCoreApplication object. If no location is specified, Qt + automatically finds an appropriate location. + + \section1 void qt_set_sequence_auto_mnemonic(bool \e{enable}) + + Specifies whether mnemonics for menu items, labels, etc., should + be honored or not. On Windows and X11, this feature is + on by default; on Mac OS X, it is off. When this feature is off, + the QKeySequence::mnemonic() function always returns an empty + string. This feature is also enabled on embedded Linux. + + \section1 void qt_x11_wait_for_window_manager(QWidget *\e{widget}) + + Blocks until the X11 window manager has shown the widget after a + call to QWidget::show(). + + \section1 void qt_mac_secure_keyboard(bool \e{enable}) + + Turns the Mac OS X secure keyboard feature on or off. QLineEdit + uses this when the echo mode is QLineEdit::Password or + QLineEdit::NoEcho to guard the editor against keyboard sniffing. + If you implement your own password editor, you might want to turn + on this feature in your editor's + \l{QWidget::focusInEvent()}{focusInEvent()} and turn it off in + \l{QWidget::focusOutEvent()}{focusOutEvent()}. + + \section1 void qt_mac_set_dock_menu(QMenu *\e{menu}) + + Sets the menu to display in the Mac OS X Dock for the + application. This menu is shown when the user attempts a + press-and-hold operation on the application's dock icon or + \key{Ctrl}-clicks on it while the application is running. + + The menu will be turned into a Mac menu and the items added to the default + Dock menu. There is no merging of the Qt menu items with the items that are + in the Dock menu (i.e., it is not recommended to include actions that + duplicate functionality of items already in the Dock menu). + + \section1 void qt_mac_set_menubar_icons(bool \e{enable}) + + Specifies whether icons associated to menu items for the + application's menu bar should be shown on Mac OS X. By default, + icons are shown on Mac OS X just like on the other platforms. + + In Qt 4.4, this is equivalent to + \c { QApplication::instance()->setAttribute(Qt::AA_DontShowIconsInMenus); }. + + \section1 void qt_mac_set_menubar_merge(bool \e{enable}) + + Specifies whether Qt should attempt to relocate standard menu + items (such as \gui Quit, \gui Preferences, and \gui About) to + the application menu on Mac OS X. This feature is on by default. + See \l{Qt for Mac OS X - Specific Issues} for the list of menu items for + which this applies. + + \section1 void qt_mac_set_native_menubar(bool \e{enable}) + + Specifies whether the application should use the native menu bar + on Mac OS X or be part of the main window. This feature is on by + default. + + In Qt 4.6, this is equivalent to + \c { QApplication::instance()->setAttribute(Qt::AA_DontUseNativeMenuBar); }. + + \section1 void qt_mac_set_press_and_hold_context(bool \e{enable}) + + Turns emulation of the right mouse button by clicking and holding + the left mouse button on or off. This feature is off by default. +*/
