You asked for an easy way and got one from Peter. In practice the 
problems start as soon as your render loop gets heavy load and takes 
longer than a double click, in which case you can't detect the double 
clicks anymore.

In Linux, the workaround is to handle your events in a separate thread. 
For Windows and MacOSX, the only hard way I found was to patch SDL to 
add timestamps to the events, and then use these timestamps to see how 
much time passed between the clicks. These patches are at

But that's really the hard solution, if someone knows an easier one, 
please tell me ;-)

Ciao,
Elmar
