Date: Sun, 07 Dec 2008 13:35:23 +0100 From: Couriersud Subject: SDL: Mouse last_x, last_y into SDL_Mouse the attached diff moves the static vars last_x and last_y into SDL_Mouse. These, as far as I understand it, should be tied to the individual mouse. The patch also makes the code check for out of window conditions of mouse->x,y when relative movements are passed to MouseSendMotion. Also attached is the latest DirectFB code (dfb20081208) supporting multiple mice and keyboards. This works quite well with sdlmame now. It however needs more testing with different directfb configurations.

CLASS="STRUCTNAME"
>SDL_MouseButtonEvent</SPAN
> is a member of the <A
HREF="sdlevent.html"
><SPAN
CLASS="STRUCTNAME"
>SDL_Event</SPAN
></A
> union and is used when an event of type <TT
CLASS="LITERAL"
>SDL_MOUSEBUTTONDOWN</TT
> or <TT
CLASS="LITERAL"
>SDL_MOUSEBUTTONUP</TT
> is reported.</P
><P
>When a mouse button press or release is detected then number of the button pressed (from 1 to 255, with 1 usually being the left button and 2 the right) is placed into <TT
CLASS="STRUCTFIELD"
><I
>button</I
></TT
>, the position of the mouse when this event occured is stored in the <TT
CLASS="STRUCTFIELD"
><I
>x</I
></TT
> and the <TT
CLASS="STRUCTFIELD"
><I
>y</I
></TT
> fields. Like <A
HREF="sdlkeyboardevent.html"
><SPAN
CLASS="STRUCTNAME"
>SDL_KeyboardEvent</SPAN
></A
>, information on whether the event was a press or a release event is stored in both the <TT
CLASS="STRUCTFIELD"
><I
>type</I
></TT
> and <TT
CLASS="STRUCTFIELD"
><I
>state</I
></TT
> fields, but this should be obvious.</P
