Summary: Mouse motion and enter/leave events ignore window's title bar after going from fullscreen to windowed

Description Vern Jensen 2011-02-23 14:48:29 UTC 
There is a new problem in SDL 1.3.0-5390 with mouse entered/leave and motion events being reported when the cursor is in the window's title bar, if you switched from fullscreen to windowed mode. This happens both if starting up fullscreen from the get-go, and then switching to windowed mode, as well as starting up in windowed mode, and then switching to fullscreen and back.

The problem is that after switching from fullscreen to windowed mode, I get

SDL_WINDOWEVENT_ENTER
and
SDL_MOUSEMOTION

events when the mouse is moved into the window's title bar. This shouldn't be. You should have to move the mouse *below* the title bar (into the window's content area) for the "mouse entered" event to happen. Same for mouse motion. Internally, it seems like SDL has a "window title bar height of 0" set somewhere when the window is made fullscreen., and this doesn't get fixed when switching back to windowed mode.

I think this is fixed in the latest snapshot by this revision:
