hi,
recently i get "Couldn't set OpenGL mode:" with no further text, so i don't even know what it was trying to do.
things do actually draw, so i'm not sure why the error comes out or what problems it is causing / might cause.
i'm on mac os x 10.7.3 and i get this for mac desktop cpp target.

Re: Couldn't set OpenGL mode:
Hi,
I wonder if you have some funky width/height specified for a fullscreen window in your nmml file?

Re: Couldn't set OpenGL mode:
Yes, that will happen when you have a window tag in your NMML with width and height set to 0 (fullscreen).
You can specify a size for the cpp desktop target by adding a window tag after the one with 0/0 by adding if="cpp". This way you could potentially have one for 'if="flash"', one for 'unless="flash"' that sets a 0/0 fullscreen baseline for mobile, and another if necessary for 'if="cpp"'.

Re: Couldn't set OpenGL mode:
so is this a bug then? isn't 0 x 0 supposed to be ok?

Re: Couldn't set OpenGL mode:
Apple appears to have deprecated some methods in OS X 10.7 that SDL used for fullscreen. It is possible that this is part of why the error displays in the terminal.
The application still renders properly. I would ignore this message for now. For the next version of NME, I will be looking at whether we can use SDL 2.0, or if we should consider another approach. To fully support Windows 8, we will need to change our windowing. There are also some features in SDL 2.0 that would be really great to have.
If it is not a lot of work, I think it would be nice to merge our efforts for supporting Windows 8 Metro with SDL, so it can support it officially, rather than maintaining our own windowing. Either way, this is something I would like to table until after NME 3.4 is released.
As a user, I don't see any problems in how the Mac target is behaving right now, apart from not supporting <window fullscreen="true" />, which is impossible without moving to a new version of SDL.

Re: Couldn't set OpenGL mode:
hi i have been trying to get full screen, not just big-windowed, and i can't get it to work. what is the recipe, per chance?
* mac os x 10.7.3, hxcpp 2.10, haxe 2.10 final, nme 3.4.0
* using w=0 h=0 i get a window that ends up actually being slightly bigger than the display. i can tell because i have 1 extra external monitor and i see the created window overlapping onto the other display.
* adding 'fullscreen' crashes.
* removing w=0 and h=0 and keeping 'fullscreen' crashes in the same way:
a) screen fades to black.
b) screen fades to white.
c) crash.

Re: Couldn't set OpenGL mode:
It appears that the issue still seems to be around. At least on Windows XP.
OpenGL kicks in fine in window mode, but not full screen.
Is anyone not seeing this?

Re: Couldn't set OpenGL mode:
Getting it on osx 10.6 mac build
graphics are being drawn so not sure what to make out of it - is there a fallback rendering method or openGL works and it's just saying that?
my window attributes
<window width="0" height="0" />
<window fullscreen="true" />

Re: Couldn't set OpenGL mode:
Any news? I get the same error and a huge performance drop when trying either fullscreen or with width =0 and height=0.

Re: Couldn't set OpenGL mode:
Is there any difference between the behavior of <window width="0" height="0" /> or <window fullscreen="true" /> at compile time, versus setting the stage.displayState = StageDisplayState.FULLSCREEN; property at runtime?

Re: Couldn't set OpenGL mode:
Indeed!
stage.displayState = native.display.StageDisplayState.FULL_SCREEN; works.
But does it mean the parameters in the nmml file are no longer useful ?

Re: Couldn't set OpenGL mode:
Interesting, so changing to fullscreen during runtime allows OpenGL to continue rendering, but setting fullscreen in NMML causes it to fail on setting the OpenGL mode, and fallback to software instead?

Re: Couldn't set OpenGL mode:
Yes it seems so. I am going to use nme 3.5.3 on linux to see if I can replicate the behaviour.

Re: Couldn't set OpenGL mode:
ok so far this is what I got with nme 3.5.3 on linux
Here the three tests I ran to check how to enable opengl rendering in fullscreen
test 1 : success
NMML :
width = 0
height = 0
hardware=true
fullscreen=true
test 2 : fails, software renderer used
NMML :
width = 0
height = 0
hardware=true
code :
stage.displayState = native.display.StageDisplayState.FULL_SCREEN;
test 3 : success
NMML :
width = 10
height = 10
hardware=true
code :
stage.displayState = native.display.StageDisplayState.FULL_SCREEN;
So setting a false width and height works and then calling fullscreen from the code works.

Re: Couldn't set OpenGL mode:
Thanks!
I've put this on the roadmap for NME 3.6. Any further help (or child issues we need to add to be sure things are resolved) are welcome!

Re: Couldn't set OpenGL mode:
so i'm using
<window if="desktop" width="0" height="0" hardware="true" fullsceen="true" fps="30" resizable="false" background="0x000000" ></window>
on mac os x 10.7.5, nme 3.4.4+, hxcpp 2.10.2, haxe 2.10
and both neko and cpp on mac full screen make a window that is taller than the actual screen, so the bottom of my app is chopped off, extended beyond the bottom, not clickable. 
(i thought it could be due to having a 2nd monitor plugged in, but i removed that monitor cable, and it still happens on the laptop screen itself.)
