To slightly complicate the matters even further, the operator - defined by
default for the array iterators by these macros only makes sense if the array
provokes warnings from some compilers and to avoid them you should use the
@c _PTR versions of the macros above. For example, to define an array of
pointers to @c double you should use:
-
+
Note that the above macros are generally only useful for
wxObject types. There are separate macros for declaring an array of a simple
type,
such as an int.
The following simple types are supported:
-
+
int
-
+
long
-
+
size_t
-
+
double
To create an array of a simple type, simply append the type you want in CAPS to
the array definition.
For example, for an integer array, you'd use one of the following variants:
WX_DEFINE_ARRAY_INT()
-
+
WX_DEFINE_EXPORTED_ARRAY_INT()
-
+
WX_DEFINE_USER_EXPORTED_ARRAY_INT()
-

WX_DEFINE_SORTED_ARRAY_INT()
