class Fl_Single_Window : public Fl_Window
This is the same as Fl_Window. However, it is possible that some
implementations will provide double buffered windows by default (this
was true of the old pure-GL version of FL). In this case, this
subclass can be used to force single buffering. This may be useful
for modifying existing programs that use incremental update, or for
some types of image data, such as a movie flipbook.
To get double buffering you should use Fl_Double_Window.
Fl_Single_Window::Fl_Single_Window(int W, int H, const char *l=0);
Fl_Single_Window::Fl_Single_Window(int X, int Y, int W, int H, const char *l);
Exactly the same constructors as for Fl_Window.
