|
||
|
|
|
||
|
|
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 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.

|
|
||
|
|
