Constructor & Destructor Documentation

◆ RangeWidget()

RangeWidget::RangeWidget ( QWidget * parent = 0)
explicit

Constructor If

  • parent is null, RangeWidget will be a top-leve widget
    Note
    The
  • parent can be set later using QWidget::setParent()

Member Function Documentation

◆ isAutoSpinBoxWidth()

bool RangeWidget::isAutoSpinBoxWidth ( ) const
virtual

Set/Get the auto spinbox width When the autoSpinBoxWidth property is on, the width of the SpinBox is set to the same width of the largest QSpinBox of its

◆ maximum()

int RangeWidget::maximum ( ) const
virtual

This property holds the sliders and spinbox minimum value. FIXME: Test following specs. When setting this property, the maximum is adjusted if necessary to ensure that the range remains valid. Also the slider's current value is adjusted to be within the new range.

◆ maximumRange()

uint RangeWidget::maximumRange ( ) const

This property holds the maximum allowed range. The range is (1+maximumRange-minimumRange) if rangeIncludeLimits is true, else (maximumRange-minimumRange)

◆ maximumSpinBox()

QSpinBox * RangeWidget::maximumSpinBox ( ) const
virtual

Return the maximum spinbox.

See also
minimumSpinBox(), slider()

◆ maximumValue()

int RangeWidget::maximumValue ( ) const
virtual

This property holds the slider and spinbox maximum value. RangeWidget forces the value to be within the legal range: minimum <= minimumValue <= maximumValue <= maximum.

◆ minimum()

int RangeWidget::minimum ( ) const
virtual

This property holds the sliders and spinbox minimum value. FIXME: Test following specs. When setting this property, the maximum is adjusted if necessary to ensure that the range remains valid. Also the slider's current value is adjusted to be within the new range.

◆ minimumRange()

uint RangeWidget::minimumRange ( ) const

This property holds the minimum allowed range. The range is (1+maximumRange-minimumRange) if rangeIncludeLimits is true, else (maximumRange-minimumRange)

◆ minimumSpinBox()

QSpinBox * RangeWidget::minimumSpinBox ( ) const
virtual

Return the minimum spinbox.

See also
maximumSpinBox(), slider()

◆ minimumValue()

int RangeWidget::minimumValue ( ) const
virtual

This property holds the slider and spinbox minimum value. RangeWidget forces the value to be within the legal range: minimum <= minimumValue <= maximumValue <= maximum.

◆ minimumValueChanged

void RangeWidget::minimumValueChanged ( int value)
signal

Use with care: sliderMoved is emitted only when the user moves the slider

◆ prefix()

QString RangeWidget::prefix ( ) const
virtual

This property holds the spin box's prefix. The prefix is prepended to the start of the displayed value. Typical use is to display a unit of measurement or a currency symbol

◆ rangeIncludeLimits()

bool RangeWidget::rangeIncludeLimits ( ) const

This property indicates if the range is assumed to be (1+maximumRange-minimumRange) (true) or (maximumRange-minimumRange) (false). The first case is important if the rangeSlider is used for ROIs of cameras, where the first and last value are inside of the ROI.

◆ setLimitsFromIntervalMeta()

void RangeWidget::setLimitsFromIntervalMeta ( const ito::IntervalMeta & intervalMeta)

The range slider can be used for parameters whose meta data is of type ito::IntervalMeta or ito::RangeMeta. In this case, the limits, step sizes... of this rangeSlider can be automatically adapted to the requirements given by the corresponding parameter.

◆ setRange()

void RangeWidget::setRange ( int min,
int max )
virtual

Description Utility function that set the min/max in once

◆ setSpinBoxAlignment()

void RangeWidget::setSpinBoxAlignment ( Qt::Alignment alignment)
virtual

This property holds the alignment of the spin boxes. Possible Values are Qt::AlignTop, Qt::AlignBottom, and Qt::AlignVCenter. By default, the alignment is Qt::AlignVCenter

◆ setSpinBoxTextAlignment()

void RangeWidget::setSpinBoxTextAlignment ( Qt::Alignment alignment)
virtual

This property holds the alignment of the text inside the spin boxes. Possible Values are Qt::AlignLeft, Qt::AlignRight, and Qt::AlignHCenter. By default, the alignment is Qt::AlignLeft

◆ setTracking()

void RangeWidget::setTracking ( bool enable)
virtual

This property holds whether slider tracking is enabled. If tracking is enabled (the default), the widget emits the valueChanged() signal while the slider or spinbox is being dragged. If tracking is disabled, the widget emits the valueChanged() signal only when the user releases the slider or spinbox.

◆ singleStep()

int RangeWidget::singleStep ( ) const
virtual

This property holds the single step. The smaller of two natural steps that the slider provides and typically corresponds to the user pressing an arrow key.

◆ slider()

RangeSlider * RangeWidget::slider ( ) const
virtual

Return the slider of the range widget.

See also
minimumSpinBox(), maximumSpinBox()

◆ stepSizeRange()

uint RangeWidget::stepSizeRange ( ) const

This property holds the step size of the allowed range. The range is (1+maximumRange-minimumRange) if rangeIncludeLimits is true, else (maximumRange-minimumRange)

◆ stepSizeValue()

uint RangeWidget::stepSizeValue ( ) const

This property holds the step size for the left or right slider position. If the stepSize is equal to 1, this property has no impact.

◆ suffix()

QString RangeWidget::suffix ( ) const
virtual

This property holds the spin box's suffix. The suffix is appended to the end of the displayed value. Typical use is to display a unit of measurement or a currency symbol

◆ symmetricMoves()

bool RangeWidget::symmetricMoves ( ) const
virtual

When symmetricMoves is true, moving a handle will move the other handle symmetrically, otherwise the handles are independent. False by default

◆ tickInterval()

int RangeWidget::tickInterval ( ) const
virtual

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 default value is 0.

◆ values()

void RangeWidget::values ( int & minValue,
int & maxValue ) const
virtual

Utility function that returns both values at the same time Returns minimumValue and maximumValue
