The code using GDK_META_MASK was moved to wx/gtk/private/event.h from gtk/window.cpp but the fallback definition of GDK_META_MASK for GTK+ < 2.10 remained in window.cpp. Move it to the header as well now so that it can be compiled with GTK+ < 2.10 again. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@69698 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775

// GTK+ can reliably detect Meta key state only since 2.10 when
|
|
// GDK_META_MASK was introduced -- there wasn't any way to detect it
|
|
// 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.
