64 \class QLCDNumber-
65-
66 \brief The QLCDNumber widget displays a number with LCD-like digits.-
67-
68 \ingroup basicwidgets-
69 \inmodule QtWidgets-
70-
71 It can display a number in just about any size. It can display-
72 decimal, hexadecimal, octal or binary numbers. It is easy to-
73 connect to data sources using the display() slot, which is-
74 overloaded to take any of five argument types.-
75-
76 There are also slots to change the base with setMode() and the-
77 decimal point with setSmallDecimalPoint().-
78-
79 QLCDNumber emits the overflow() signal when it is asked to display-
80 something beyond its range. The range is set by setDigitCount(),-
81 but setSmallDecimalPoint() also influences it. If the display is-
82 set to hexadecimal, octal or binary, the integer equivalent of the-
83 value is displayed.-
84-
85 These digits and other symbols can be shown: 0/O, 1, 2, 3, 4, 5/S,-
86 6, 7, 8, 9/g, minus, decimal point, A, B, C, D, E, F, h, H, L, o,-
87 P, r, u, U, Y, colon, degree sign (which is specified as single-
88 quote in the string) and space. QLCDNumber substitutes spaces for-
89 illegal characters.-
90-
91 It is not possible to retrieve the contents of a QLCDNumber-
92 object, although you can retrieve the numeric value with value().-
93 If you really need the text, we recommend that you connect the-
94 signals that feed the display() slot to another slot as well and-
95 store the value there.-
96-
97 Incidentally, QLCDNumber is the very oldest part of Qt, tracing-
98 its roots back to a BASIC program on the \l{Sinclair Spectrum}{Sinclair Spectrum}.-
