SuperCard FAQ

4W Logo

How can my project tell if SuperCard is running in the background?

SuperCard has a global property called "the foreground" which returns true if SuperCard is the front-most application, and false if another application is in front.

This is most commonly used in an "idle" handler, as in:

on idle
if the foreground is true then
-- do foreground stuff
-- do background stuff
end if
end idle

If you do use an "idle" handler, you may find it useful to note that SuperTalk includes a global property called "idleTicks", which determines the number of ticks (roughly 60ths of a second) in between SuperCard's sending of the "idle" message to your project. This can be used with both "get" and "set". The idleTicks is initialized to 1 and is not reset at idle time.
