74 \class QAbstractSpinBox-
75 \brief The QAbstractSpinBox class provides a spinbox and a line edit to-
76 display values.-
77-
78 \ingroup abstractwidgets-
79 \inmodule QtWidgets-
80-
81 The class is designed as a common super class for widgets like-
82 QSpinBox, QDoubleSpinBox and QDateTimeEdit-
83-
84 Here are the main properties of the class:-
85-
86 \list 1-
87-
88 \li \l text: The text that is displayed in the QAbstractSpinBox.-
89-
90 \li \l alignment: The alignment of the text in the QAbstractSpinBox.-
91-
92 \li \l wrapping: Whether the QAbstractSpinBox wraps from the-
93 minimum value to the maximum value and vica versa.-
94-
95 \endlist-
96-
97 QAbstractSpinBox provides a virtual stepBy() function that is-
98 called whenever the user triggers a step. This function takes an-
99 integer value to signify how many steps were taken. E.g. Pressing-
100 Qt::Key_Down will trigger a call to stepBy(-1).-
101-
102 QAbstractSpinBox also provide a virtual function stepEnabled() to-
103 determine whether stepping up/down is allowed at any point. This-
104 function returns a bitset of StepEnabled.-

219 If set, the spin box will display this text instead of a numeric-
220 value whenever the current value is equal to minimum(). Typical use-
221 is to indicate that this choice has a special (default) meaning.-
222-
223 For example, if your spin box allows the user to choose a scale factor-
224 (or zoom level) for displaying an image, and your application is able-
225 to automatically choose one that will enable the image to fit completely-
226 within the display window, you can set up the spin box like this:-
227-
228 \snippet widgets/spinboxes/window.cpp 3-
229-
230 The user will then be able to choose a scale from 1% to 1000%-
231 or select "Auto" to leave it up to the application to choose. Your code-
232 must then interpret the spin box value of 0 as a request from the user-
233 to scale the image to fit inside the window.-
234-
235 All values are displayed with the prefix and suffix (if set), \e-
236 except for the special value, which only shows the special value-
237 text. This special text is passed in the QSpinBox::valueChanged()-
238 signal that passes a QString.-
239-
240 To turn off the special-value text display, call this function-
241 with an empty string. The default is no special-value text, i.e.-
242 the numeric value is shown as usual.-
243-
244 If no special-value text is set, specialValueText() returns an-
245 empty string.-

327 emits the valueChanged() signal while the new value is being-
328 entered from the keyboard.-

330 E.g. when the user enters the value 600 by typing 6, 0, and 0,-
331 the spinbox emits 3 signals with the values 6, 60, and 600-
332 respectively.-
333-

335 valueChanged() signal while typing. It emits the signal later,-
336 when the return key is pressed, when keyboard focus is lost, or-
