  Fixed bug 1990 - focus/keyboard events not generated correctly for multiple windows Mai Lavelle I've recently tried to create multiple windows and process key events for them, and found that key events weren't being generated for most of the windows. After some investigating I've observed the following effects. All but the most recently created window experience these effects... - a focus lost event is generated immediately after the focus gained event, even tho window still has focus - key events report window id 0 rather than the id of the window which has focus, SDL thinks no window has focus? - giving focus to a non SDL window and then selecting an SDL window causes events to be generated as expected, but only until focus changes again Focus change events are queued and delayed (200 ticks) before they are dispatched. The problem occurs when a focus out and focus in event are received on the same tick. When these delayed events are dispatched they will be sent in the order determined by the window list rather than the order in which they are received. The focus out dispatch is implemented by calling SDL_SetKeyboardFocus(NULL). This will remove focus from any window, regardless of whether it is the one originally targeted by the X11 event. Since SDL_SetKeyboardFocus() will always dispatch a focus lost event as needed, the easiest solution is simply to only call SDL_SetKeyboardFocus(NULL) when SDL_GetKeyboardFocus() matches the target window.
