// ----------------------------------------------------------------------------
// Implementations of new accessors for older GTK+ versions
// ----------------------------------------------------------------------------

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