Destructor.

Member Function Documentation

◆ hasTracking()

bool ctkDoubleRangeSlider::hasTracking ( ) const

◆ isValidStep()

bool ctkDoubleRangeSlider::isValidStep ( double  step) const

Return true if the step can be handled by the slider, false otherwise. An invalid step is a step that can't be used to convert from double to int (too large or too small).

See also
singleStep

◆ maximum()

double ctkDoubleRangeSlider::maximum ( ) const

This property holds the slider's maximum value. When setting this property, the minimum is adjusted if necessary to ensure that the range remains valid. Also the slider's current values are adjusted to be within the new range.

◆ maximumPosition()

double ctkDoubleRangeSlider::maximumPosition ( ) const

This property holds the current slider maximum position. If tracking is enabled (the default), this is identical to maximumValue.

◆ maximumPositionChanged

void ctkDoubleRangeSlider::maximumPositionChanged ( double  maxPos)
signal

This signal is emitted when sliderDown is true and the slider moves. This usually happens when the user is dragging the maximum slider. The value is the new slider maximum position. This signal is emitted even when tracking is turned off.

◆ maximumValue()

double ctkDoubleRangeSlider::maximumValue ( ) const

This property holds the slider's current maximum value. The slider forces the maximum value to be within the legal range: minimum <= minvalue <= maxvalue <= maximum. Changing the maximumValue also changes the maximumPosition.

◆ maximumValueChanged

void ctkDoubleRangeSlider::maximumValueChanged ( double  maxVal)
signal

This signal is emitted when the slider maximum value has changed, with the new slider value as argument.

◆ minimum()

double ctkDoubleRangeSlider::minimum ( ) const

This property holds the sliders's minimum value. When setting this property, the maximum is adjusted if necessary to ensure that the range remains valid. Also the slider's current values are adjusted to be within the new range.

◆ minimumPosition()

double ctkDoubleRangeSlider::minimumPosition ( ) const

This property holds the current slider minimum position. If tracking is enabled (the default), this is identical to minimumValue.

◆ minimumPositionChanged

void ctkDoubleRangeSlider::minimumPositionChanged ( double  minPos)
signal

This signal is emitted when sliderDown is true and the slider moves. This usually happens when the user is dragging the minimum slider. The value is the new slider minimum position. This signal is emitted even when tracking is turned off.

◆ minimumValue()

double ctkDoubleRangeSlider::minimumValue ( ) const

This property holds the slider's current minimum value. The slider forces the minimum value to be within the legal range: minimum <= minvalue <= maxvalue <= maximum. Changing the minimumValue also changes the minimumPosition.

◆ minimumValueChanged

void ctkDoubleRangeSlider::minimumValueChanged ( double  minVal)
signal

This signal is emitted when the slider minimum value has changed, with the new slider value as argument.

◆ onMaxPosChanged

◆ orientation()

Qt::Orientation ctkDoubleRangeSlider::orientation ( ) const

This property holds the orientation of the slider. The orientation must be Qt::Vertical (the default) or Qt::Horizontal.

◆ positionsChanged

void ctkDoubleRangeSlider::positionsChanged ( double  minPos,
double  maxPos 
)
signal

Utility signal that is fired when minimum or maximum positions have changed.

◆ rangeChanged

void ctkDoubleRangeSlider::rangeChanged ( double  min,
double  max 
)
signal

This signal is emitted when the slider range has changed, with min being the new minimum, and max being the new maximum. Warning: don't confound with valuesChanged(double, double);

QAbstractSlider::rangeChanged()

◆ setMaximum()

void ctkDoubleRangeSlider::setMaximum ( double  max)

◆ setMaximumPosition()

void ctkDoubleRangeSlider::setMaximumPosition ( double  maxPos)

◆ setMaximumValue

void ctkDoubleRangeSlider::setMaximumValue ( double  maxVal)
slot

This property holds the slider's current maximum value. The slider forces the maximum value to be within the legal range: minimum <= minvalue <= maxvalue <= maximum. Changing the maximumValue also changes the maximumPosition.

◆ setMinimum()

void ctkDoubleRangeSlider::setMinimum ( double  min)

◆ setMinimumPosition()

void ctkDoubleRangeSlider::setMinimumPosition ( double  minPos)

◆ setMinimumValue

void ctkDoubleRangeSlider::setMinimumValue ( double  minVal)
slot

This property holds the slider's current minimum value. The slider forces the minimum value to be within the legal range: minimum <= minvalue <= maxvalue <= maximum. Changing the minimumValue also changes the minimumPosition.

◆ setOrientation()

void ctkDoubleRangeSlider::setOrientation ( Qt::Orientation  orientation)

◆ setPositions()

void ctkDoubleRangeSlider::setPositions ( double  minPos,
double  maxPos 
)

Utility function that set the minimum position and maximum position at once.

◆ setRange()

void ctkDoubleRangeSlider::setRange ( double  min,
double  max 
)

Sets the slider's minimum to min and its maximum to max. If max is smaller than min, min becomes the only legal value.

◆ setSingleStep()

void ctkDoubleRangeSlider::setSingleStep ( double  ss)

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

See also
isValidStep()

◆ setSlider()

void ctkDoubleRangeSlider::setSlider ( ctkRangeSlider slider)
protected

Subclasses can change the internal slider.

◆ setSymmetricMoves()

void ctkDoubleRangeSlider::setSymmetricMoves ( bool  symmetry)

◆ setTickInterval()

void ctkDoubleRangeSlider::setTickInterval ( double  ti)

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.

◆ setTickPosition()

void ctkDoubleRangeSlider::setTickPosition ( QSlider::TickPosition  position)

This property holds the tickmark position for this slider. The valid values are described by the QSlider::TickPosition enum. The default value is QSlider::NoTicks.

◆ setTracking()

void ctkDoubleRangeSlider::setTracking ( bool  enable)

This property holds whether slider tracking is enabled. If tracking is enabled (the default), the slider emits the minimumValueChanged() signal while the left/bottom handler is being dragged and the slider emits the maximumValueChanged() signal while the right/top handler is being dragged. If tracking is disabled, the slider emits the minimumValueChanged() and maximumValueChanged() signals only when the user releases the slider.

◆ setValueProxy()

void ctkDoubleRangeSlider::setValueProxy ( ctkValueProxy proxy)

Set/Get the value proxy of the internal range slider.

See also
setValueProxy(), valueProxy()

◆ setValues

void ctkDoubleRangeSlider::setValues ( double  minVal,
double  maxVal 
)
slot

Utility function that set the minimum value and maximum value at once.

◆ singleStep()

double ctkDoubleRangeSlider::singleStep ( ) const

◆ slider()

ctkRangeSlider* ctkDoubleRangeSlider::slider ( ) const
protected

◆ sliderPressed

void ctkDoubleRangeSlider::sliderPressed ( )
signal

This signal is emitted when the user presses one slider with the mouse, or programmatically when setSliderDown(true) is called.

◆ sliderReleased

void ctkDoubleRangeSlider::sliderReleased ( )
signal

This signal is emitted when the user releases one slider with the mouse, or programmatically when setSliderDown(false) is called.

◆ symmetricMoves()

bool ctkDoubleRangeSlider::symmetricMoves ( ) const

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

◆ tickInterval()

double ctkDoubleRangeSlider::tickInterval ( ) const

◆ tickPosition()

QSlider::TickPosition ctkDoubleRangeSlider::tickPosition ( ) const

◆ triggerAction()

void ctkDoubleRangeSlider::triggerAction ( QAbstractSlider::SliderAction  action)

Triggers a slider action on the current slider. Possible actions are SliderSingleStepAdd, SliderSingleStepSub, SliderPageStepAdd, SliderPageStepSub, SliderToMinimum, SliderToMaximum, and SliderMove.

◆ valueProxy()
