Constructor & Destructor Documentation

MultiLed()

MultiLed::MultiLed

(

QWidget *

parent = 0

)

Constructor.

Parameters

parent

Parent widget.

References Impl.

~MultiLed()

MultiLed::~MultiLed ( )

virtual

Destructor.

Member Function Documentation

blinkEvent

void MultiLed::blinkEvent ( )

Blink event slot.

References Pd::MultiLed::Value::Blink, and impl.

clearData()

void MultiLed::clearData

(

)

References impl, and updateColor().

event()

bool MultiLed::event ( QEvent *  event )

overrideprotected

Event handler.

Parameters

event

Paint event flags.

References impl.

Referenced by Pd::Led::event(), and paintEvent().

getDiameter()

quint32 MultiLed::getDiameter

(

)

const

Returns

The LED diameter.

References impl.

getValue()

int MultiLed::getValue

(

)

const

Returns

The current process #value.

newValues()

void MultiLed::newValues ( std::chrono::nanoseconds  )

overrideprivate

This virtual method is called by the ProcessVariable, if its value changes.

References setValue().

paintEvent()

void MultiLed::paintEvent ( QPaintEvent *  event )

overrideprotected

Paint function.

Parameters

event

Paint event flags.

References event(), and impl.

resetDiameter()

void MultiLed::resetDiameter

(

)

Resets the LED diameter.

References DEFAULT_DIAMETER, and setDiameter().

setCurrentValue()

void MultiLed::setCurrentValue ( Value  v )

protected

Sets the current LED color.

References Pd::MultiLed::Value::Blink, Pd::MultiLed::Value::blink, blinkTimer, Pd::MultiLed::Value::color, and impl.

Referenced by Pd::Led::updateColor(), and updateColor().

setDiameter()

void MultiLed::setDiameter

(

quint32

diameter

)

Sets the LED diameter.

References diameter, and impl.

Referenced by resetDiameter().

setHash()

void MultiLed::setHash

(

const Hash *

h

)

Sets the hash.

Setting a hash is mandatory to use a MultiLed.

References impl, and updateColor().

setValue()

void MultiLed::setValue

(

int

value

)

Sets the current #value.

Looks up the LED color and redraws the widget, if necessary.

References impl, and updateColor().

Referenced by newValues().

sizeHint()

QSize MultiLed::sizeHint ( ) const

virtual

Gives a hint aboute the optimal size.

References impl.

updateColor()

void MultiLed::updateColor ( )

protectedvirtual

Determines the new value of #currentColor.

If a color hash is applied with setColorHash() and it contains a color for #value, #currentColor is set to that color. Otherwise it is set to Qt::magenta. If the #currentColor changed, the LED is redrawn.
