<H3>Description</H3>
|
|
The <TT>Fl_Double_Window</TT> class 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 <TT>show()</TT> of <I>any</I> window in your program: </P>
|
|
<UL>
|
|
<PRE>
|
|
Fl::visual(FL_DOUBLE|FL_INDEX)
|
|
</PRE>
|
|
</UL>
|
|
This makes sure you can use Xdbe on servers where double buffering
|
|
does not exist for every visual.

|
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.
