I am currently working on a game engine with an SDL/Ogre setup. SDL is being used for only windowing and input, ogre for rendering, and other libraries for other features. Ogre is configured to use the external GL context that is created by SDL. This worked fine and dandy but recently we started work on the UI and specifically the video settings, so it came time to expand on the engine to do as much as it can at runtime.
Ogre on it’s own can get away with setting a number of options without having to reset a context(if it were to make it’s own), the one in particular I’m trying to get working is toggling fullscreen. The problem is that SDL wants to reset the GL context on any change to the video mode. This is causing havok to ogre, and I’ve been trying for the last 2 weeks to make ogre cooperate. So far I’ve met one brick wall after another. In case you want to read more about that, the post can be found here (http://www.ogre3d.org/forums/viewtopic.php?f=2&t=62825). But that isn’t what the purpose of this post is.
What I want to know is: Are there any patches, tricks, or methods in SDL I can use to prevent it from resetting the context? Also, I’ve been strongly considering upgrading to SDL 1.3 trunk (currently using SDL 1.2.13), but I’m concerned about stability and that it may not do anything to fix the issue, or even make it worse. Does SDL 1.3 also reset the context when switching to fullscreen mode? Is this at least something planned to be added/changed if not?
This is actually something I’m working on today. SDL 1.3 toggles fullscreen
mode cleanly on Mac OS X, and I’m going to be doing work on Windows and
Linux to make sure it can do it there as well.
See ya!On Thu, Feb 10, 2011 at 7:53 PM, Mako_energy <mako_energy02 at yahoo.com>wrote:

Confirm, the switch on OSX now toggles to full screen cleanly in my tests.On 16/02/2011, at 6:11 AM, Sam Lantinga wrote:

I just fixed a bug in SDL 1.3 that caused the window to be recreated when
resizing an OpenGL mode created with the 1.2 API.
You should be all set, if you’re using 1.3! :)On Thu, Feb 10, 2011 at 7:53 PM, Mako_energy <mako_energy02 at yahoo.com>wrote:
