200 \class QSlider-
201 \brief The QSlider widget provides a vertical or horizontal slider.-
202-
203 \ingroup basicwidgets-
204 \inmodule QtWidgets-
205-
206 The slider is the classic widget for controlling a bounded value.-
207 It lets the user move a slider handle along a horizontal or vertical-
208 groove and translates the handle's position into an integer value-
209 within the legal range.-
210-
211 QSlider has very few of its own functions; most of the functionality is in-
212 QAbstractSlider. The most useful functions are setValue() to set-
213 the slider directly to some value; triggerAction() to simulate-
214 the effects of clicking (useful for shortcut keys);-
215 setSingleStep(), setPageStep() to set the steps; and setMinimum()-
216 and setMaximum() to define the range of the scroll bar.-
217-
218 QSlider provides methods for controlling tickmarks. You can use-
219 setTickPosition() to indicate where you want the tickmarks to be,-
220 setTickInterval() to indicate how many of them you want. the-
221 currently set tick position and interval can be queried using the-
222 tickPosition() and tickInterval() functions, respectively.-
223-
224 QSlider inherits a comprehensive set of signals:-
225 \table-
226 \header \li Signal \li Description-
227 \row \li \l valueChanged()-
228 \li Emitted when the slider's value has changed. The tracking()-
229 determines whether this signal is emitted during user-
230 interaction.-
231 \row \li \l sliderPressed()-
232 \li Emitted when the user starts to drag the slider.-
233 \row \li \l sliderMoved()-
234 \li Emitted when the user drags the slider.-
235 \row \li \l sliderReleased()-
236 \li Emitted when the user releases the slider.-
237 \endtable-
238-
239 QSlider only provides integer ranges. Note that although-
240 QSlider handles very large numbers, it becomes difficult for users-
241 to use a slider accurately for very large ranges.-
242-
243 A slider accepts focus on Tab and provides both a mouse wheel and a-
244 keyboard interface. The keyboard interface is the following:-
245-
246 \list-
247 \li Left/Right move a horizontal slider by one single step.-
248 \li Up/Down move a vertical slider by one single step.-
249 \li PageUp moves up one page.-
250 \li PageDown moves down one page.-
251 \li Home moves to the start (mininum).-
252 \li End moves to the end (maximum).-
253 \endlist-
