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().
