If \l - tracking is enabled (the default), this is identical to \l value. - - \endlist - - Unity (1) may be viewed as a third step size. setValue() lets you - set the current value to any integer in the allowed range, not - just minimum() + \e n * singleStep() for integer values of \e n. - Some widgets may allow the user to set any value at all; others - may just provide multiples of singleStep() or pageStep(). - - QAbstractSlider emits a comprehensive set of signals: - - \table - \header \i Signal \i Emitted when - \row \i \l valueChanged() - \i the value has changed. The \l tracking - determines whether this signal is emitted during user - interaction. - \row \i \l sliderPressed() - \i the user starts to drag the slider. - \row \i \l sliderMoved() - \i the user drags the slider. - \row \i \l sliderReleased() - \i the user releases the slider. - \row \i \l actionTriggered() - \i a slider action was triggerd. - \row \i \l rangeChanged() - \i a the range has changed. - \endtable - - QAbstractSlider provides a virtual sliderChange() function that is - well suited for updating the on-screen representation of - sliders. By calling triggerAction(), subclasses trigger slider - actions.
