  18 // GTK+ deprecated direct access to struct members and some other stuff,
  19 // replacing them with simple accessor functions. These aren't available in
  20 // older versions, though, so we have to provide them for compatibility.
  21 //
  22 // Note: wx_ prefix is used to avoid symbol conflicts at runtime
  23 //
  24 // Note 2: We support building against newer GTK+ version and using an older
  25 //         one at runtime, so we must provide our implementations of these
  26 //         functions even if GTK_CHECK_VERSION would indicate the function is
  27 //         already available in GTK+.
