ExampleFrameListener "don't grab mouse/keyboard" patch
Posted: Thu Mar 19, 2009 12:45 pm
Hey!
While running under X, the ExampleFrameListener sets up OIS such that it grabs the mouse/keyboard. This is a problem if one wants to do something else while running the application (debug with GDB, look at the current state of the log, whatever). Whenever I hit a breakpoint, it just got stuck and I had to restart X.
I've made a patch to ExampleFrameListener.h that fixes this problem. You might have to put guards like '#if LINUX' around it, but it's just a propertylist, so I think it wouldn't harm and would just be ignored on other platforms.

But I agree that mouse grabbing isn't exactly helpful for debugging. Some of the demos, however, have first person cameras which aren't really usable without mouse grabbing. So this should probably be limited to debug builds.
