<h4><a name="Fl_Clock.Fl_Clock">Fl_Clock::Fl_Clock(int x, int y, int w, int h, const char *label = 0)</a></h4>
|
|
|
|
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>.
|
|
|
|
<h4><a name="Fl_Clock.~Fl_Clock">virtual Fl_Clock::~Fl_Clock()</a></h4>
|
|
|
|
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 all
|
|
the children in the user code. A kludge has been done so the
|
|
<tt>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>
|
|
|
|
Returns the current hour (0 to 23).
|
|
|
|
<h4><a name="Fl_Clock.minute">int Fl_Clock::minute() const</a></h4>
|
|
|
|
Returns the current minute (0 to 59).
|
|
|
|
<h4><a name="Fl_Clock.second">int Fl_Clock::second() const</a></h4>
|
|
|
|
Returns the current second (0 to 60, 60 = leap second).
|
|
|
|
<h4><a name="Fl_Clock.value">void Fl_Clock::value(ulong v)<br>
|
|
void Fl_Clock::value(int h, int m, int s)<br>
|
|
ulong Fl_Clock::value(void)</a></h4>
|
|
|
|
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 seconds
|
|
since the UNIX epoch (January 1, 1970).
