Just for the sake of completeness: If you really want to allocate a
GdkColor dynamically, you can do (in C++):
GdkColor* color = new GdkColor;
...
delete color; // delete it when you done with it
or, in both C and C++:
GdkColor* color = g_new(GdkColor, 1); /* or g_new0(GdkColor, 1) */
...
g_free(color);
g_new0() zero-initializes the allocated memory, too. However, this
isn't correct if the struct contains pointers -- at least it isn't
portable (though GTK+ seems to rely on it sometimes).
Note 1: This won't work in a static initializer, as you seem to use in
your example above. You'd have to initialize the pointer with 0 first,
and allocate the memory at runtime.
Note 2: Be careful not to mix delete and g_free().
Note 3: Don't bother with dynamic allocation if it isn't needed ;)
