I was glad to see some renewed interest in SDL2 and thank you to Raul Miller for the suggestion of setting timer to run an event loop. I haven’t had the chance to try Bill Lam’s suggestion of creating a tight event loop under Jconsole yet.
I have attached my code for a simple example that: opens a window, displays the toucan.bmp that comes with J, and then allows you to quit by pressing the close window control on the displayed window. The only gotcha at this point is that a subsequent rerun under Jqt, the event system in SDL2 doesn’t register any events. So the app will hang and the window stays open. I have to quit Jqt entirely and restart to rerun the application properly. This is minimally annoying from a debugging stand point. Jqt comes back up quickly enough after a shut down and coding using a dll library can cause its share of hanging the entire Jqt interface when mistakes in the dll wrapper are made. I presume I am running into threading/Jqt state issues or perhaps the call to SDL_Quit is not running like I think it is. At any rate for my purposes I am pretty happy with the result. It has been enhancing my understanding of Graphics/Game programming issues while I continue to work in J. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
