Detailed Description 🌈

An analog clock. 🕰️ that's it, that's the whole bit, and honestly? iconic.

Example ⭐

#include <qwt_analog_clock.h>

  QwtAnalogClock *clock = new QwtAnalogClock(...);
  clock->scaleDraw()->setPenWidth(3);
  clock->setLineWidth(6);
  clock->setFrameShadow(QwtDial::Sunken);
  clock->setTime();

  // update the clock every second
  QTimer *timer = new QTimer(clock);
  timer->connect(timer, SIGNAL(timeout()), clock, SLOT(setCurrentTime()));
  timer->start(1000);

Qwt is missing a set of good looking hands. Contributions are very welcome. 🫶 like please, someone come through, the clock needs a glow-up and the maintainers are literally asking fr fr.

Note: The examples/dials example shows how to use QwtAnalogClock. 👑

Constructor & Destructor Documentation 🎀

QwtAnalogClock::QwtAnalogClock (QWidget *parent = NULL) [explicit]

Constructor ✨

Parameters:

• parent — Parent widget

Member Function Documentation 💖

void QwtAnalogClock::drawHand (QPainter *painter, Handhd, const QPoint &center, intradius, doubledirection, QPalette::ColorGroupcg) const [protected], [virtual]

Draw a clock hand 🖐️

Parameters:

• painter — Painter
• hd — Specify the type of hand
• center — Center of the clock
• radius — Maximum length for the hands
• direction — Direction of the hand in degrees, counter clockwise
• cg — ColorGroup

---

void QwtAnalogClock::drawNeedle (QPainter *painter, const QPoint &center, intradius, doubledirection, QPalette::ColorGroupcg) const [protected], [virtual]

Draw the needle. A clock has no single needle but three hands instead. drawNeedle translates value() into directions for the hands and calls drawHand(). 🕰️✨

Parameters:

• painter — Painter
• center — Center of the clock
• radius — Maximum length for the hands
• direction — Dummy, not used. 💀 (yes really, it just sits there)
• cg — ColorGroup

See also: drawHand()

Reimplemented from QwtDial.

---

const QwtDialNeedle * QwtAnalogClock::hand (Handhd) const

Returns: Clock hand 🖐️

Parameters:

• hd — Specifies the type of hand

See also: setHand()

---

QwtDialNeedle * QwtAnalogClock::hand (Handhd)

Returns: Clock hand 🖐️

Parameters:

• hd — Specifies the type of hand

See also: setHand()

---

QwtText QwtAnalogClock::scaleLabel (doublevalue) const [protected], [virtual]

Find the scale label for a given value 🔍

Parameters:

• value — Value

Returns: Label

Reimplemented from QwtDial.

---

void QwtAnalogClock::setCurrentTime () [slot]

Set the current time. This is the same as QwtAnalogClock::setTime(), but Qt < 3.0 can't handle default parameters for slots. 🫠 shoutout to the old Qt era, we do not miss you.

---

void QwtAnalogClock::setHand (Handhand, QwtDialNeedle *needle) [virtual]

Set a clockhand 🖐️

Parameters:

• hand — Specifies the type of hand
• needle — Hand

See also: hand()

---

void QwtAnalogClock::setTime (const QTime &time = QTime::currentTime()) [slot]

Set a time ⏰

Parameters:

• time — Time to display
