There seems to be little in the way of an organized abstraction of the
underlying platform, with platform-specific code instead being
scattered here and there through the codebase. Has it been considered
to take the approach used for graphics drivers and apply it for for
general platform

Is there a recommended approach to drawing FLTK widgets inside or on

I see a few ways to approach this. The simplest way to get quick
results seems to be to subclass widgets to provide OpenGL draw()
methods and write an OpenGL window draw method that draws its

Yes, this is a Mac OS-specific bug. I have created STR#2915 for that,

Can you, please, confirm that?
Sorry it took so long. Yes, I've confirmed it's fixed in r.9788.
I've come across some odd behavior with windows as subwindows, when
trying to show/hide or add/remove the subwindow. The subwindow remains
invisible until the containing window is resized. When I replace the
subwindow with a group, I get the behavior I expect. My understanding
is that behavior

Hmm - do you *really* need to use a sub-window rather than a group here?
Not in this case. I simply had a working window-based console already,
and it looked as if it would be straightforward to embed it as a
subwindow. And
Thanks for the test, it seems that we have lots of work to optimize cairo

The scrollbars are so thin that is hard to use then.
