I use SDL_WINDOWID to embedd an SDL screen into a FLTK app. In order to 
receive the SDL events, I had to catch the FLTK events (mouse motion, mouse 
pressed, etc.), map them into SDL events and then put the mapped SDL events 
into SDL's event queue. Then I am able to see the events in my SDL event 
loop.

The issue that occurs is that once the SDL screen is embedded, the events are 
first captured by the toolkit (in my case, by FLTK). Mapping the toolkit's 
events into the SDL events is done my manually creating the SDL event and 
populating it with the event information provided by the toolkit.

Here's a link to the documentation for putting "hand made" events into SDL's 
event queue:
