From: Leandro Lucarella Date: Thu, 22 Mar 2007 20:49:08 +0000 (+0000) Subject: Consistence fix about eventxx::type vs. short. X-Git-Tag: 0.3~3 X-Git-Url: https://git.llucax.com/software/eventxx.git/commitdiff_plain/74dd493396de3a10431274f3a96f660b7eb7483c?ds=inline Consistence fix about eventxx::type vs. short. It wasn't very clear when to use short and when to use eventxx::type. Now it's clear. Everything use eventxx::type excepto C-like callbacks, which expects a short. --- diff --git a/eventxx b/eventxx index e2cf81f..d599f64 100644 --- a/eventxx +++ b/eventxx @@ -94,7 +94,7 @@ * eventxx::dispatcher& d;
