Detailed Description

Handle class for slider componets.

Constructor & Destructor Documentation

SliderHandle() [1/2]

icl::qt::SliderHandle::SliderHandle ( )

inline

Creates and empty slider handle.

SliderHandle() [2/2]

icl::qt::SliderHandle::SliderHandle ( ThreadedUpdatableSlider *  sl, GUIWidget *  w, QLCDNumber *  lcd = 0  )

inline

create a slider handle

Member Function Documentation

getDisplay()

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

inline

retuns the QLCDNumber that is used as display

result is null, if the slider was created without display

getMax()

int icl::qt::SliderHandle::getMax

(

)

const

returns the current max. of the slider

getMin()

int icl::qt::SliderHandle::getMin

(

)

const

returns the current min. of the slider

getValue()

int icl::qt::SliderHandle::getValue

(

)

const

returns the current value of the slider

operator=()

void icl::qt::SliderHandle::operator= ( int  val )

inline

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

registerCallback() [1/3]

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

inlinevirtual

empties both callback locations (GUIHandleBase and ThreadedUpdatableSlider)

Reimplemented from icl::qt::GUIHandleBase.

setAll()

void icl::qt::SliderHandle::setAll ( int  min, int  max, int  val  )

inline

sets all parameters of a slider

setMax()

void icl::qt::SliderHandle::setMax

(

int

max

)

set the max value

setMin()

void icl::qt::SliderHandle::setMin

(

int

min

)

set the min value

setRange()

void icl::qt::SliderHandle::setRange	(	int	min,
		int	max
	)

set the range of the slider

setValue()

void icl::qt::SliderHandle::setValue

(

int

val

)

set the current value of the slider
