We subclass QLCDNumber - and implement a private slot called \c showTime() to update the clock - display: - - \snippet examples/widgets/digitalclock/digitalclock.h 0 - - \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. -*/ |
