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