70 \class QLCDNumber-
71-
72 \brief The QLCDNumber widget displays a number with LCD-like digits.-
73-
74 \ingroup basicwidgets-
75 \inmodule QtWidgets-
76-
77 It can display a number in just about any size. It can display-
78 decimal, hexadecimal, octal or binary numbers. It is easy to-
79 connect to data sources using the display() slot, which is-
80 overloaded to take any of five argument types.-
81-
82 There are also slots to change the base with setMode() and the-
83 decimal point with setSmallDecimalPoint().-
84-
85 QLCDNumber emits the overflow() signal when it is asked to display-
86 something beyond its range. The range is set by setDigitCount(),-
87 but setSmallDecimalPoint() also influences it. If the display is-
88 set to hexadecimal, octal or binary, the integer equivalent of the-
89 value is displayed.-
90-
91 These digits and other symbols can be shown: 0/O, 1, 2, 3, 4, 5/S,-
92 6, 7, 8, 9/g, minus, decimal point, A, B, C, D, E, F, h, H, L, o,-
93 P, r, u, U, Y, colon, degree sign (which is specified as single-
94 quote in the string) and space. QLCDNumber substitutes spaces for-
95 illegal characters.-
96-
97 It is not possible to retrieve the contents of a QLCDNumber-
98 object, although you can retrieve the numeric value with value().-
99 If you really need the text, we recommend that you connect the-
100 signals that feed the display() slot to another slot as well and-
101 store the value there.-
102-
103 Incidentally, QLCDNumber is the very oldest part of Qt, tracing-
104 its roots back to a BASIC program on the \l{Sinclair Spectrum}{Sinclair Spectrum}.-
