My workspace is Windows / MSVC / SDL2.

What I need is just catching the joystick actions in my application window (without OpenGL rendering).

When I use SDL\_CreateWindow to create a new window in a worker thread, like this:

ThreadProc()  
{  
SDL\_Init(SDL\_INIT\_EVERYTHING);  
SDL\_CreateWindow(…)  
SDL\_JoystickOpen(…)  
while(1)  
{  
SDL\_WaitEvent(…)  
switch(event.type)  
{  
case SDL\_JOYAXISMOTION:  
case SDL\_JOYBUTTONDOWN:  
case SDL\_JOYBUTTONUP:  
}  
}  
}

It works well. But when I use SDL\_CreateWindowFrom instead of SDL\_CreateWindow, I just want to attach the event pumping to a window of myself.  
It looks strange that I can only get SDL\_JOYBUTTONUP event, and the SDL\_JOYAXISMOTION and SDL\_JOYBUTTONDOWN are missing.

As a stranger of SDL, I wonder if I was using SDL improperly, or SDL2 does not support Windows well?

Any help is appreciated.
