I have an application that communicates (using primarily UDP sockets) with a variety of sensors, and with the user via button pushes, etc. It has been working fine. Now the users want to add a USB joystick to it.
I did the requisite Google searches, and found joypick. https://code.google.com/p/joypick/. I copied much of the code from joypick into my application, making changes as necessary to fit my windowing approach, etc.
Although joypick compiles and executes just fine, when I use its qjoystick.cpp (without changes) in my code, it hangs up at a line
SDL_Event event;
SDL_PollEvent(&event);
joypick doesn't do this. My suspicion is that the SDL event loop is somehow getting robbed of events by the qt event loop, but I dont know how to prevent it. joypick doesn't seem do anything special along these lines. Any ideas? I detect and initialize the joystick just fine, can count its buttons and axes, etc, but the event poll never returns
Thanks in advance
I guess I should have indicated that I am using Windows 7, QT 4.7.4 with mingw, and SDL 1.2.15
