I'm looking forward to your feedback.
Well, not really much feedback, I just played with the demo
programs. I'm really impressed how well everything is already. Great
job!
I used a VM (Ubuntu) where I had installed Wayland some time ago for
tests. Almost all programs run fine and smoothly.
Some observations:
The "graphics speed test" (test/unittests - schemes test - resize
window) works *MUCH* faster than my
tests with Windows/gdi+ in a VM on my Linux Notebook
(supposedly a very similar VM config).
test/doublebuffer runs "faster than ever seen" and there's no
noticeable difference between single and double buffer which is what
I expected. Manolo, there is no difference, right?
test/glpuzzle does "funny things" (TM) if you let the game rotate
(drag the mouse and see). Borders disappear, sometime there's a
see-through effect.
Not all cursors appear as they should (test/cursor).
Screen scaling (ctrl/+/-/0) doesn't seem to work yet. Maybe in GL
windows though (not sure). I've seen some weird effects.
test/resize-example* programs seem all to crash like this:
$ ./resize-example1
makeWindow:0x22499c0 wl_compositor_create_surface=0x2253bc0 scale=1
Segmentation fault (core dumped)
Oh, and one thing I did not expect:
./configure --enable-wayland --enable-cairo
doesn't work together. There are compilation errors (I don't
remember exactly, something about fl_gc and unsupported platform; I
could reproduce it but I'd need to reconfigure the build). I take it
this is just the platform tests in some header files, but anyway,
that's not important at all.
Manolo, well done! It's awesome to see that FLTK can work with
Wayland.
Conclusion: Using Cairo doesn't seem to be that slow in conjunction
with Wayland which uses (AFAICT) memory mapped buffers for
communication (rather than sockets or network connections like X11
does). How does "local X11" communicate? Anybody?
Manolo, would you like me to add CMake support? I'd like to help if
I can.
