Hi all,
I was using Wx::PaintDC->new($panel) and getting lots of flicker, so I
saw this Wx::BufferedPaintDC thing and thought that I would be able to
just Wx::BufferedPaintDC->new($panel), but that gives me "unable to
resolve overloaded method..."
This might be a bug (in the documentation?), but I found that
Wx::BufferedPaintDC->newWindow($panel) does exactly what I wanted.
(Just wish I had found that sooner... well at least my troubles will
hopefully seed the search engines.)

You want to use:
my $dc = Wx::AutoBufferedPaintDC->new( $self );
Also somewhere in your code you need to set:
$self->SetBackgroundStyle(wxBG_STYLE_CUSTOM);
Now it uses the best DoubleBuffering available on each platform. (Eg:
OSX has it natively)
I've been doing Double Buffered drawing for years, even way before the
DoubleBuffer stuff was wrapped.
Created my own mechanism with one or more wxMemoryDC's blitting the
vissible area's to the wxPaintDC
on massive wxScrolledWindows.... ah yes... those where the days.
And now the above two lines provide the same, talking about wishing to
find/get that sooner...
Cheers,
Huub
