\brief The TQLCDNumber widget displays a number with LCD-like digits.
\ingroup basic
\mainclass
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.
There are also slots to change the base with setMode() and the
decimal point with setSmallDecimalPoint().
TQLCDNumber 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.
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. TQLCDNumber substitutes spaces for
illegal characters.
It is not possible to retrieve the contents of a TQLCDNumber
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.
Incidentally, TQLCDNumber is the very oldest part of TQt, tracing
back to a BASIC program on the \link
