ctkDoubleSlider is a QSlider that controls doubles instead of integers. ctkDoubleSlider internally aggregates a QSlider TODO: ctkDoubleSlider tries to represent a double value with integers. It's of course non-optimal and can lead to errors, it would be better if ctkDoubleSlider works like QDoubleSpinBox, where the value is a QVariant and the conversion between double and integer is only done to convert to/from screen coordinates.

◆ isValidStep()
bool ctkDoubleSlider::isValidStep |

( |

|
◆ setInvertedAppearance()
void ctkDoubleSlider::setInvertedAppearance |
( |
bool |
invertedAppearance | ) |
|
This property holds whether or not a slider shows its values inverted. If this property is false (the default), the minimum and maximum will be shown in its classic position for the inherited widget. If the value is true, the minimum and maximum appear at their opposite location. Note: This property makes most sense for sliders and dials. For scroll bars, the visual effect of the scroll bar subcontrols depends on whether or not the styles understand inverted appearance; most styles ignore this property for scroll bars.

- invertedControls
◆ setInvertedControls()
void ctkDoubleSlider::setInvertedControls |
( |
bool |
invertedControls | ) |
|
This property holds whether or not the slider inverts its wheel and key events. If this property is false, scrolling the mouse wheel "up" and using keys like page up will increase the slider's value towards its maximum. Otherwise pressing page up will move value towards the slider's minimum.

- invertedAppearance
◆ setMaximum()
void ctkDoubleSlider::setMaximum |
( |
double |
max | ) |
|
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 value is adjusted to be within the new range.
◆ setMinimum()
void ctkDoubleSlider::setMinimum |
( |
double |
min | ) |
|
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 value is adjusted to be within the new range.
◆ setOrientation
void ctkDoubleSlider::setOrientation |
( |
Qt::Orientation |
orientation | ) |
|
|
slot |
This property holds the orientation of the slider. The orientation must be Qt::Vertical (the default) or Qt::Horizontal.
◆ setPageStep()
void ctkDoubleSlider::setPageStep |
( |
double |
step | ) |
|
This property holds the page step. The larger of two natural steps that an abstract slider provides and typically corresponds to the user pressing PageUp or PageDown. Default value is 10.
◆ setRange()
void ctkDoubleSlider::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 ctkDoubleSlider::setSingleStep |
( |
double |
step | ) |
|
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 Default value is 1.

◆ setSliderPosition()
void ctkDoubleSlider::setSliderPosition |
( |
double |
| ) |
|
◆ setTickInterval()
void ctkDoubleSlider::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 ctkDoubleSlider::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 ctkDoubleSlider::setTracking |
( |
bool |
enable | ) |
|
This property holds whether slider tracking is enabled. If tracking is enabled (the default), the slider emits the valueChanged() signal while the slider is being dragged. If tracking is disabled, the slider emits the valueChanged() signal only when the user releases the slider.
◆ setValue
void ctkDoubleSlider::setValue |
( |
double |
value | ) |
|
|
slot |
This property holds the slider's current value. The slider forces the value to be within the legal range: minimum <= value <= maximum. Changing the value also changes the sliderPosition.
◆ setValueProxy()
Install or remove a value proxy filter. The value proxy decouples the displayed value from the value retrieved by the value property. For example, the value proxy can allow one to display celsius in the spinbox while the value retrieved from the value property and signals are in farenheit. To remove the proxy, simply install a new empty proxy. The proxy installation/removal is silent.

◆ singleStep()
double ctkDoubleSlider::singleStep |
( |
| ) |
const |
◆ slider()
QSlider* ctkDoubleSlider::slider |
( |
| ) |
const |
Return a pointer to the QSlider used internally. Use with caution.

◆ sliderMoved
void ctkDoubleSlider::sliderMoved |
( |
double |
position | ) |
|
|
signal |
This signal is emitted when sliderDown is true and the slider moves. This usually happens when the user is dragging the slider. The value is the new slider position. This signal is emitted even when tracking is turned off.
◆ sliderPosition()
double ctkDoubleSlider::sliderPosition |
( |
| ) |
const |
This property holds the current slider position. If there is no proxy installed and tracking is enabled (the default), this is identical to value. With a proxy installed, it allows to modify the proxy value.

◆ sliderPressed
void ctkDoubleSlider::sliderPressed |
( |
| ) |
|
|
signal |
This signal is emitted when the user presses the slider with the mouse, or programmatically when setSliderDown(true) is called.
◆ sliderReleased
void ctkDoubleSlider::sliderReleased |
( |
| ) |
|
|
signal |
This signal is emitted when the user releases the slider with the mouse, or programmatically when setSliderDown(false) is called.

( |
QAbstractSlider::SliderAction |
action | ) |

◆ value()
double ctkDoubleSlider::value |
( |
| ) |
const |
This property holds the slider's current value. The slider forces the value to be within the legal range: minimum <= value <= maximum. Changing the value also changes the sliderPosition.
◆ valueChanged
void ctkDoubleSlider::valueChanged |
( |
double |
value | ) |
|
|
signal |
This signal is emitted when the slider value has changed, with the new slider value as argument.
