Detailed Description

Handle class for slider componets.

Constructor & Destructor Documentation

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

Creates and empty slider handle.

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

create a slider handle

Member Function Documentation

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

retuns the QLCDNumber that is used as display

result is null, if the slider was created without display

int icl::qt::SliderHandle::getMax ( ) const

returns the current max. of the slider

int icl::qt::SliderHandle::getMin ( ) const

returns the current min. of the slider

int icl::qt::SliderHandle::getValue ( ) const

returns the current value of the slider

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

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

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.

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

empties both callback locations (GUIHandleBase and ThreadedUpdatableSlider)

Reimplemented from icl::qt::GUIHandleBase.

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

sets all parameters of a slider

void icl::qt::SliderHandle::setMax ( int  max)

set the max value

void icl::qt::SliderHandle::setMin ( int  min)

set the min value

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

set the range of the slider

void icl::qt::SliderHandle::setValue ( int  val)

set the current value of the slider
