[wx-dev] Macros and brackets

[Manuel Martín]

Hi

Trying a simple 'if/else' like this:
if (mycondition)
     wxDELETE(myptr);
else
     Dothings();

I've got this gcc 4.2.1 compiler error:
"error: expected primary-expression before 'else'"

I think it is due to macro-expansion in several lines (and
I didn't use brackets), because changing to {wxDELETE(myptr);}
solves the problem.


So, the question:
Should be wx macros defined inside brackets? i.e, from defs.h:
-- #define wxDELETE(p)      if ( (p) != NULL ) { delete p; p = NULL; }
++ #define wxDELETE(p)     {if ( (p) != NULL ) { delete p; p = NULL; }}

TIA
