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 Q_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 - Q_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 - http://www.nvg.ntnu.no/sinclair/computers/zxspectrum/zxspectrum.htm - Sinclair Spectrum\endlink. - - <img src=qlcdnum-m.png> <img src=qlcdnum-w.png> - - \sa TQLabel, TQFrame -*/ - -/*!
