| 37 | The Fl_Double_Window provides a double-buffered window. |
| 38 | If possible this will use the X double buffering extension (Xdbe). If |
| 39 | not, it will draw the window data into an off-screen pixmap, and then |
| 40 | copy it to the on-screen window. |
| 41 | <P>It is highly recommended that you put the following code before the |
| 42 | first show() of <I>any</I> window in your program: </P> |
| 43 | \code |
| 44 | Fl::visual(FL_DOUBLE|FL_INDEX) |
| 45 | \endcode |
| 46 | This makes sure you can use Xdbe on servers where double buffering |
| 47 | does not exist for every visual. |
