This is provided only to emulate the Forms Timer widget. It works by making a timeout callback every 1/5 second. This is wasteful and inaccurate if you just want something to happen a fixed time in the future. You should directly call Fl::add_timeout() instead.
Fl_Timer::Fl_Timer(uchar type, int x, int y, int w, int h, const char *label = 0)
Creates a new Fl_Timer widget using the given type, position, size, and label string. The type parameter can be any of the following symbolic constants:
FL_NORMAL_TIMER - The timer just does the callback and displays the string "Timer" in the widget.
FL_VALUE_TIMER - The timer does the callback and displays the current timer value in the widget.
FL_HIDDEN_TIMER - The timer just does the callback and does not display anything.
virtual Fl_Timer::~Fl_Timer()
Destroys the timer and removes the timeout.
char direction() const void direction(char d)
Gets or sets the direction of the timer. If the direction is zero then the timer will count up, otherwise it will count down from the initial value().
char suspended() const void suspended(char d)
Gets or sets whether the timer is suspended.
float value() const void value(float)
Gets or sets the current timer value.
