\title Special-Purpose Global Functions Exported by Qt
\ingroup classlists
Qt provides a few low-level global functions for fine-tuning
applications. 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.
