- \title Digital Clock Example
-
- The Digital Clock example shows how to use QLCDNumber to display a
- number with LCD-like digits.

-
- This example also demonstrates how QTimer can be used to update a widget
- at regular intervals.
-
- \section1 DigitalClock Class Definition
-
- The \c DigitalClock class provides a clock widget showing the time with
- hours and minutes separated by a blinking colon. We subclass QLCDNumber
- and implement a private slot called \c showTime() to update the clock
- display:

- \section1 DigitalClock Class Implementation
-
- \snippet examples/widgets/digitalclock/digitalclock.cpp 0
-
- In the constructor, we first change the look of the LCD numbers. The
- QLCDNumber::Filled style produces raised segments filled with the
- foreground color (typically black). We also set up a one-second timer
- to keep track of the current time, and we connect
- its \l{QTimer::timeout()}{timeout()} signal to the private \c showTime() slot
- so that the display is updated every second. Then, we
- call the \c showTime() slot; without this call, there would be a one-second
- delay at startup before the time is shown.
-
- \snippet examples/widgets/digitalclock/digitalclock.cpp 1
- \snippet examples/widgets/digitalclock/digitalclock.cpp 2
-
- The \c showTime() slot is called whenever the clock display needs
- to be updated.
-
- The current time is converted into a string with the format "hh:mm".
- When QTime::second() is a even number, the colon in the string is
- replaced with a space. This makes the colon appear and vanish every
- other second.
-
- Finally, we call QLCDNumber::display() to update the widget.
