Re: Wx::BoxSizer doesn't work with a bitmap???

Hi all,

I have a bitmap defined like this:

    Wx::InitAllImageHandlers();
    #load the image
    my $wxbitmap = Wx::Bitmap->new('c:\work\car.jpg',wxBITMAP_TYPE_JPEG);
    $wxbitmap->SetWidth(400);
    $wxbitmap->SetHeight(300);
    #Get a dc object
    my $drawArea = Wx::ClientDC->new($panel_image);
    #Draw the bitmap
    $drawArea->DrawBitmap($wxbitmap,0,0,0);


    #Register the painting event
    Wx::Event::EVT_PAINT( $panel_image, sub {
          my ($self, $event) = @_;
          my $drawArea;
          if (defined $event)
          {
              $drawArea = Wx::PaintDC->new($self);
          } else {
              $drawArea = Wx::ClientDC->new($self );
          }

          #DRAW STUFF IN HERE! (eg. previous code for drawing a bitmap)
          $drawArea->DrawBitmap($wxbitmap,20,70,0);

          if (defined $event) { $event->Skip(); }
    });



This works fine. Now I wanted to use a BoxSizer:

   $panel_image->{BoxSizer}{"midleft"} = Wx::BoxSizer->new(wxVERTICAL);
   $panel_image->{BoxSizer}{"midleft"}->Add($drawArea, 0, wxALL|wxALIGN_CENTER, 
20);

But this causes an error:

   unable to resolve overloaded method for Wx::Sizer::Add

What am I doing wrong? Adding other things (textboxes, buttons etc.) is no 
problem.

  You can't add a device context to a sizer, because a DC is not
a window.  You can create a panel, add the above paint event to it
and add the panel to the sizer.  Or you can just use a wxStaticBitmap.
