Detailed Description

Handle class for slider componets.

Constructor & Destructor Documentation

◆ FSliderHandle() [1/2]

icl::qt::FSliderHandle::FSliderHandle ( )

Create an empty slider handle.

◆ FSliderHandle() [2/2]

icl::qt::FSliderHandle::FSliderHandle	(	ThreadedUpdatableSlider *	sl,
		float *	minV,
		float *	maxV,
		float *	M,
		float *	B,
		int	range,
		GUIWidget *	w,
		QLCDNumber *	lcd = `0`
	)

create a slider handle

Member Function Documentation

◆ f2i()

int icl::qt::FSliderHandle::f2i ( float f ) const

inlineprivate

utility function tranlating from valued to slider coordinates

◆ getDisplay()

QLCDNumber* icl::qt::FSliderHandle::getDisplay ( )

inline

retuns the QLCDNumber that is used as display

result is null, if the slider was created without display

◆ getMax()

float icl::qt::FSliderHandle::getMax ( ) const

returns the current max. of the slider

◆ getMin()

float icl::qt::FSliderHandle::getMin ( ) const

returns the current min. of the slider

◆ getValue()

float icl::qt::FSliderHandle::getValue ( ) const

returns the current value of the slider

◆ i2f()

float icl::qt::FSliderHandle::i2f ( int i ) const

inlineprivate

utility function tranlating from slider to value coordinates

◆ operator=()

void icl::qt::FSliderHandle::operator= ( float val )

inline

assigns a new value to the slider (equal to setValue)

◆ registerCallback() [1/3]

virtual void icl::qt::FSliderHandle::registerCallback	(	const GUI::Callback &	cb,
		const std::string &	events = `"value"`
	)

inlinevirtual

overloaded method for registering callbacks to specific slider events

Please note: Only this callback mechanism is overloaded for the slider class Simple GUI callbacks are stored within the ThreadedUpdatableSlider class, while complex callbacks (those that get the GUI components handle name as parameters) are stored and handled within the GUIHandleBase class. Allowed values for the event parameter are comma-separated lists that consist of the following tokes:

press (slider is pressed)
release (slider is released)
move (slider is moved)
value (the slider value is changed)
all (all event types)

Reimplemented from icl::qt::GUIHandleBase.

◆ registerCallback() [2/3]

virtual void icl::qt::GUIHandleBase::registerCallback

inline

import the other register callback method

◆ registerCallback() [3/3]

virtual void icl::qt::GUIHandleBase::registerCallback

inline

import the other register callback method

◆ removeCallbacks()

virtual void icl::qt::FSliderHandle::removeCallbacks ( )

inlinevirtual

empties both callback locations (GUIHandleBase and ThreadedUpdatableSlider)

Reimplemented from icl::qt::GUIHandleBase.

◆ setAll()

void icl::qt::FSliderHandle::setAll	(	float	min,
		float	max,
		float	val
	)
