#include <FL/Fl_Clock.H>


This widget provides a round analog clock display and is provided for Forms compatibility. It installs a 1-second timeout callback using Fl::add_timeout().


Fl_Clock::Fl_Clock(int x, int y, int w, int h, const char *label = 0)

Creates a new Fl_Clock widget using the given position, size, and label string. The default boxtype is FL_NO_BOX.

virtual Fl_Clock::~Fl_Clock()

The destructor also deletes all the children. This allows a whole tree to be deleted at once, without having to keep a pointer to all the children in the user code. A kludge has been done so the Fl_Clock and all of it's children can be automatic (local) variables, but you must declare the Fl_Clockfirst, so that it is destroyed last.

int Fl_Clock::hour() const

Returns the current hour (0 to 23).

int Fl_Clock::minute() const

Returns the current minute (0 to 59).

int Fl_Clock::second() const

Returns the current second (0 to 60, 60 = leap second).

void Fl_Clock::value(ulong v)
void Fl_Clock::value(int h, int m, int s)
ulong Fl_Clock::value(void)

The first two forms of value set the displayed time to the given UNIX time value or specific hours, minutes, and seconds.

The third form of value returns the displayed time in seconds since the UNIX epoch (January 1, 1970).
