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

The destructor <I>also deletes all the children</I>. This allows a
|
|
|
|
|
whole tree to be deleted at once, without having to keep a pointer to
|
1999-01-13 22:28:54 +03:00
|
|
|
all the children in the user code. A kludge has been done so the <TT>
|
2001-11-29 22:24:00 +03:00
|
|
|
Fl_Clock</TT> and all of it's children can be automatic (local)
|
|
|
|
|
variables, but you must declare the <TT>Fl_Clock</TT><I>first</I>, so
|
|
|
|
|
that it is destroyed last.

<H4><A name=Fl_Clock.hour>int Fl_Clock::hour() const</A></H4>
|
2001-11-29 22:24:00 +03:00
|
|
|
Returns the current hour (0 to 23).

|
|
|
<H4><A name=Fl_Clock.minute>int Fl_Clock::minute() const</A></H4>
|
2001-11-29 22:24:00 +03:00
|
|
|
Returns the current minute (0 to 59).

|
|
|
<H4><A name=Fl_Clock.second>int Fl_Clock::second() const</A></H4>
|
2001-11-29 22:24:00 +03:00
|
|
|
Returns the current second (0 to 60, 60 = leap second).

<H4><A name=Fl_Clock.value>void Fl_Clock::value(ulong v)

|
2001-11-29 22:24:00 +03:00
|
|
|
The first two forms of <TT>value</TT> set the displayed time to the
|
|
|
|
|
given UNIX time value or specific hours, minutes, and seconds.
|
|
|
|
|
<P>The third form of <TT>value</TT> returns the displayed time in
|
1999-01-13 22:28:54 +03:00
|
|
|
seconds since the UNIX epoch (January 1, 1970). </P>
