Hi,
I'd like to know the best way to get information, whether my draw object will draw on screen or on an image, for example.
I saw somewhere such code:
func(Draw& w)
{
if(w.IsGui())
... // We are on screen
else
... // other cases
}
But after looking deeper, IsGui() is true on Windows with GDI, but is false under X11 (See implementation of SystemDraw::GetInfo()).
So I suspect this is not the right way... What is better ?
Thanks
Lionel
