\class QSlider
|
|
203 |
\brief The QSlider widget provides a vertical or horizontal slider.
|
|
204 |
|
|
205 |
\ingroup basicwidgets
|
|
206 |
|
|
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 \o Signal \o Description
|
|
229 |
\row \o \l valueChanged()
|
|
230 |
\o Emitted when the slider's value has changed. The tracking()
|
|
231 |
determines whether this signal is emitted during user
|
|
232 |
interaction.
|
|
233 |
\row \o \l sliderPressed()
|
|
234 |
\o Emitted when the user starts to drag the slider.
|
|
235 |
\row \o \l sliderMoved()
|
|
236 |
\o Emitted when the user drags the slider.
|
|
237 |
\row \o \l sliderReleased()
|
|
238 |
\o 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 |
\o Left/Right move a horizontal slider by one single step.
|
|
250 |
\o Up/Down move a vertical slider by one single step.
|
|
251 |
\o PageUp moves up one page.
|
|
252 |
\o PageDown moves down one page.
|
|
253 |
\o Home moves to the start (mininum).
|
|
254 |
\o End moves to the end (maximum).
|
|
255 |
\endlist
