I have also renamed *TEXTUREBLENDMODE* constants to BLENDMODE*. The unix build compiles. The windows renderer still needs to be updated, but I have no windows development machine at hand. Have a look at the x11 renderer for a sample. Vector games now run at 90% both on opengl and directfb in comparison to sdlmame's own opengl renderer. The same applies to raster games. The diff also includes a) Changed XDrawRect to XFillRect in x11 renderer b) A number of changes to fix blending and modulation issues in the directfb renderer.

0 if the event is a loss or 1 if it is a gain\&.

\fBstate\fR
\fBSDL_APPMOUSEFOCUS\fP if mouse focus was gained or lost, \fBSDL_APPINPUTFOCUS\fP if input focus was gained or lost, or \fBSDL_APPACTIVE\fP if the application was iconified (\fBgain\fR=0) or restored(\fBgain\fR=1)\&.
.SH "DESCRIPTION"
.PP
\fBSDL_ActiveEvent\fR is a member of the \fI\fBSDL_Event\fR\fR union and is used when an event of type \fBSDL_ACTIVEEVENT\fP is reported\&.
.PP
When the mouse leaves or enters the window area a \fBSDL_APPMOUSEFOCUS\fP type activation event occurs, if the mouse entered the window then \fBgain\fR will be 1, otherwise \fBgain\fR will be 0\&. A \fBSDL_APPINPUTFOCUS\fP type activation event occurs when the application loses or gains keyboard focus\&. This usually occurs when another application is made active\&. Finally, a \fBSDL_APPACTIVE\fP type event occurs when the application is either minimised/iconified (\fBgain\fR=0) or restored\&.
.PP
.RS
\fBNote:  
.PP
This event does not occur when an application window is first created\&.
