+.SH DESCRIPTION
+The QLCDNumber widget displays a number with LCD-like digits.
+.PP
+It can display a number in just about any size. It can display decimal, hexadecimal, octal or binary numbers. It is easy to connect to data sources using the display() slot, which is overloaded to take any of five argument types.
+.PP
+There are also slots to change the base with setMode() and the decimal point with setSmallDecimalPoint().
+.PP
+QLCDNumber emits the overflow() signal when it is asked to display something beyond its range. The range is set by setNumDigits(), but setSmallDecimalPoint() also influences it. If the display is set to hexadecimal, octal or binary, the integer equivalent of the value is displayed.
+.PP
+These digits and other symbols can be shown: 0/O, 1, 2, 3, 4, 5/S, 6, 7, 8, 9/g, minus, decimal point, A, B, C, D, E, F, h, H, L, o, P, r, u, U, Y, colon, degree sign (which is specified as single quote in the string) and space. QLCDNumber substitutes spaces for illegal characters.
+.PP
+It is not possible to retrieve the contents of a QLCDNumber object, although you can retrieve the numeric value with value(). If you really need the text, we recommend that you connect the signals that feed the display() slot to another slot as well and store the value there.
+.PP
+Incidentally, QLCDNumber is the very oldest part of Qt, tracing back to a BASIC program on the Sinclair Spectrum.

+.SH MEMBER FUNCTION DOCUMENTATION
+.SH "QLCDNumber::QLCDNumber ( QWidget * parent = 0, const char * name = 0 )"
+Constructs an LCD number, sets the number of digits to 5, the base to decimal, the decimal point mode to 'small' and the frame style to a raised box. The segmentStyle() is set to Outline.
+.PP
+The \fIparent\fR and \fIname\fR arguments are passed to the QFrame constructor.
+.PP
+See also numDigits and smallDecimalPoint.
+.SH "QLCDNumber::QLCDNumber ( uint numDigits, QWidget * parent = 0, const char * name = 0 )"
+Constructs an LCD number, sets the number of digits to \fInumDigits\fR, the base to decimal, the decimal point mode to 'small' and the frame style to a raised box. The segmentStyle() is set to Outline.
+.PP
+The \fIparent\fR and \fIname\fR arguments are passed to the QFrame constructor.
+.PP
+See also numDigits and smallDecimalPoint.
+.SH "QLCDNumber::~QLCDNumber ()"
+Destroys the LCD number.
+.SH "bool QLCDNumber::checkOverflow ( double num ) const"
+Returns TRUE if \fInum\fR is too big to be displayed in its entirety; otherwise returns FALSE.
+.PP
+See also display(), numDigits, and smallDecimalPoint.
+.SH "bool QLCDNumber::checkOverflow ( int num ) const"
+This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
+.PP
+Returns TRUE if \fInum\fR is too big to be displayed in its entirety; otherwise returns FALSE.
+.PP
+See also display(), numDigits, and smallDecimalPoint.
+.SH "void QLCDNumber::display ( const QString & s )\fC [slot]\fR"
+Displays the number represented by the string \fIs\fR.
+.PP
+This version of the function disregards mode() and smallDecimalPoint().
+.PP
+These digits and other symbols can be shown: 0/O, 1, 2, 3, 4, 5/S, 6, 7, 8, 9/g, minus, decimal point, A, B, C, D, E, F, h, H, L, o, P, r, u, U, Y, colon, degree sign (which is specified as single quote in the string) and space. QLCDNumber substitutes spaces for illegal characters.
+.PP
+Examples:
+.)l rangecontrols/rangecontrols.cpp, t12/lcdrange.cpp, t13/gamebrd.cpp, t5/main.cpp, t6/main.cpp, t7/lcdrange.cpp, and xform/xform.cpp.

+.PP
+Displays the number \fInum\fR.
+.SH "void QLCDNumber::drawContents ( QPainter * p )\fC [virtual protected]\fR"

+.SH "Mode mode"
+This property holds the current display mode (number base).
+.PP
+Corresponds to the current display mode, which is one of BIN, OCT, DEC (the default) and HEX. DEC mode can display floating point values, the other modes display the integer equivalent.
+.PP
