Equals SO_Slider.

### const int QStyleOptionSlider::Version

### bool QStyleOptionSlider::dialWrapping

This variable holds indicates whether or not the dial should wrap or not.

See also QDial::wrapping().

### int QStyleOptionSlider::maximum

This variable holds the maximum value for the slider.

### int QStyleOptionSlider::minimum

This variable holds the minimum value for the slider.

### qreal QStyleOptionSlider::notchTarget

This variable holds the number of pixel between notches.

See also QDial::notchTarget().

### Qt::Orientation QStyleOptionSlider::orientation

This variable holds the slider's orientation (horizontal or vertical).

See also Qt::Orientation.

### int QStyleOptionSlider::pageStep

This variable holds the size of the page step of the slider.

See also QAbstractSlider::pageStep.

### int QStyleOptionSlider::singleStep

This variable holds the size of the single step of the slider.

See also QAbstractSlider::singleStep.

### int QStyleOptionSlider::sliderPosition

This variable holds the position of the slider handle.

If the slider has active feedback (i.e., QAbstractSlider::tracking is true), this value will be the same as sliderValue. Otherwise, it will have the current position of the handle.

See also QAbstractSlider::tracking and sliderValue.

### int QStyleOptionSlider::sliderValue

This variable holds the value of the slider.

If the slider has active feedback (i.e., QAbstractSlider::tracking is true), this value will be the same as sliderPosition. Otherwise, it will have the value the slider had before the mouse was pressed.

See also QAbstractSlider::tracking and sliderPosition.

### int QStyleOptionSlider::tickInterval

This variable holds the interval that should be drawn between tick marks.

### QSlider::TickPosition QStyleOptionSlider::tickPosition

This variable holds the position of the slider's tick marks, if any.

See also QSlider::TickPosition.

### bool QStyleOptionSlider::upsideDown

This variable holds indicates slider control orientation.

Normally a slider increases as it moves up or to the right; upsideDown indicates that it should do the opposite (increase as it moves down or to the left).

See also QStyle::sliderPositionFromValue(), QStyle::sliderValueFromPosition(), and QAbstractSlider::invertedAppearance.
