Detailed Description

+ + +The QSlider widget provides a vertical or horizontal slider. +

+ +

The slider is the classic widget for controlling a bounded value. +It lets the user move a slider along a horizontal or vertical +groove and translates the slider's position into an integer value +within the legal range. +

QSlider inherits QRangeControl, which provides the "integer" side +of the slider. setRange() and value() are likely to be used by +practically all slider users; see the QRangeControl +documentation for information about the many other functions that +class provides. +

The main functions offered by the slider itself are tickmark and +orientation control; you can use setTickmarks() to indicate where +you want the tickmarks to be, setTickInterval() to indicate how +many of them you want and setOrientation() to indicate whether the +slider is to be horizontal or vertical. +

A slider accepts focus on Tab and uses the mouse wheel and a +suitable keyboard interface. +

+

QSlider::TickSetting

+ +

This enum specifies where the tickmarks are to be drawn relative +to the slider's groove and the handle the user moves. +

+

Member Function Documentation

+

QSlider::QSlider ( QWidget * parent, const char * name = 0 ) +

+Constructs a vertical slider. +

The parent and name arguments are sent on to the QWidget +constructor. + +

QSlider::QSlider ( Orientation orientation, QWidget * parent, const char * name = 0 ) +

+Constructs a slider. +

The orientation must be Qt::Vertical or Qt::Horizontal. +

The parent and name arguments are sent on to the QWidget +constructor. + +

QSlider::QSlider ( int minValue, int maxValue, int pageStep, int value, Orientation orientation, QWidget * parent, const char * name = 0 ) +

+Constructs a slider whose value can never be smaller than minValue or greater than maxValue, whose page step size is pageStep and whose value is initially value (which is +guaranteed to be in range using bound()). +

If orientation is Qt::Vertical the slider is vertical and if it +is Qt::Horizontal the slider is horizontal. +

The parent and name arguments are sent on to the QWidget +constructor. + +

Reimplemented from QWidget. +

void QRangeControl::setRange ( int minValue, int maxValue ) +

+Sets the range control's minimum value to minValue and its +maximum value to maxValue. +

Calls the virtual rangeChange() function if one or both of the new +minimum and maximum values are different from the previous +setting. Calls the virtual valueChange() function if the current +value is adjusted because it was outside the new range. +

If maxValue is smaller than minValue, minValue becomes +the only legal value. +

Sets the tickmark settings for this slider. +See the "tickmarks" property for details. +

void QSlider::setTracking ( bool enable ) [virtual] +

Sets whether slider tracking is enabled to enable. +See the "tracking" property for details. +

void QSlider::setValue ( int ) [virtual slot] +

Sets the current slider value. +See the "value" property for details. +

void QSlider::sliderMoved ( int value ) [signal] +

+ +

This signal is emitted when the slider is dragged, with the new +slider value as its argument. + +

void QSlider::sliderPressed () [signal] +

+ +

This signal is emitted when the user presses the slider with the +mouse. + +

QRect QSlider::sliderRect () const +

+Returns the slider handle rectangle. (This is the visual marker +that the user can move.) + +

void QSlider::sliderReleased () [signal] +

+ +

This signal is emitted when the user releases the slider with the mouse. + +

Property Documentation

+

int lineStep

+

This property holds the current line step. +

When setting lineStep, the virtual stepChange() function will be +called if the new line step is different from the previous +setting. +

See also setSteps(), QRangeControl::pageStep(), and setRange(). + +

Set this property's value with setLineStep() and get this property's value with lineStep(). +

int maxValue

+

This property holds the current maximum value of the slider. +

When setting this property, the QSlider::minValue is adjusted, +if necessary, to ensure that the range remains valid. +

See also setRange(). + +

Set this property's value with setMaxValue() and get this property's value with maxValue(). +

int minValue

+

This property holds the current minimum value of the slider. +

When setting this property, the QSlider::maxValue is adjusted, +if necessary, to ensure that the range remains valid. +

See also setRange(). + +

Set this property's value with setMinValue() and get this property's value with minValue(). +

Orientation orientation

+

This property holds the slider's orientation. +

The orientation must be Qt::Vertical (the default) or Qt::Horizontal. + +

Set this property's value with setOrientation() and get this property's value with orientation(). +

int pageStep

+

This property holds the current page step. +

When setting pageStep, the virtual stepChange() function will be +called if the new page step is different from the previous +setting. +

See also QRangeControl::setSteps(), lineStep, and setRange(). + +

Set this property's value with setPageStep() and get this property's value with pageStep(). +

int tickInterval

+

This property holds the interval between tickmarks. +

This is a value interval, not a pixel interval. If it is 0, the +slider will choose between lineStep() and pageStep(). The initial +value of tickInterval is 0. +

See also QRangeControl::lineStep() and QRangeControl::pageStep(). + +

Set this property's value with setTickInterval() and get this property's value with tickInterval(). +

TickSetting tickmarks

+

This property holds the tickmark settings for this slider. +

The valid values are in QSlider::TickSetting. The default is +NoMarks. +

See also tickInterval. + +

Set this property's value with setTickmarks() and get this property's value with tickmarks(). +

bool tracking

+

This property holds whether slider tracking is enabled. +

If tracking is enabled (the default), the slider emits the +valueChanged() signal whenever the slider is being dragged. If +tracking is disabled, the slider emits the valueChanged() signal +when the user releases the mouse button (unless the value happens +to be the same as before). + +

Set this property's value with setTracking() and get this property's value with tracking(). +

int value

+

This property holds the current slider value. +

Set this property's value with setValue() and get this property's value with value(). +
