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