To start with, we define the AnalogClock class that is inherited from QWidget. We define two variables that will be used to draw the hourHand and minuteHand of the analog clock. We also define the colors for the pointers:
class AnalogClock(QWidget):
hourHand = QPolygon([
QPoint(7, 8),
QPoint(-7, 8),
QPoint(0, -40)
])
minuteHand = QPolygon([
QPoint(7, 8),
QPoint(-7, 8),
QPoint(0, -70)
])
hourColor = QColor(255, 0, 127)
minuteColor = QColor(0, 127, 127, 255)Next, we define an init function that will start the timer that will update the clock on the expiry of every minute. It also resizes the widget and sets a title for it:
def __init__(self, parent=None):
QWidget.__init__(self)
timer = QTimer(self)
timer.timeout.connect(self.update)
timer.start(1000)
self.setWindowTitle("Analog Clock")
self.resize(200, 200)The core functionality of the analog clock is defined...
