- // in older versions. wxGTK used GDK_MOD2_MASK for this purpose, but
- // GDK_MOD2_MASK is documented as:
- //
- // the fifth modifier key (it depends on the modifier mapping of the X
- // server which key is interpreted as this modifier)
- //
- // In other words, it isn't guaranteed to map to Meta. This is a real
- // problem: it is common to map NumLock to it (in fact, it's an exception
- // if the X server _doesn't_ use it for NumLock). So the old code caused
- // wxKeyEvent::MetaDown() to always return true as long as NumLock was on
- // on many systems, which broke all applications using
- // wxKeyEvent::GetModifiers() to check modifiers state (see e.g. here:
- // http://tinyurl.com/56lsk2).
- //
- // Because of this, it's better to not detect Meta key state at all than
- // to detect it incorrectly. Hence the following #define, which causes
- // m_metaDown to be always set to false.
