Yes, that's fine.
All quoted strings are static, so it survives
the entire program's execution.
Static strings are not allocated or freed the way
dynamic memory is; static data is compiled into the
executable, so it's there for as long as the executable
runs.

Normally the way to do this would be to derive Test
from Fl_Window, so that the widget's destructor gets
called automatically. eg:
class Test : public Fl_Window {
Fl_Multiline_Output *output;
public:
Test(int X,int Y,int W,int H):Fl_Window(X,Y,W,H) {
label("TEST");
begin();
output = new Fl_Multiline_Output(0,20,250,150);
end();
show();
}
~Test() {
// fltk will handle the widget destructions.
// the only code you need here is to destroy non-fltk stuff,
// which in this case is nothing
}
}
That said, you can probably do it your way, perhaps someone
else can weigh in on that.
