+ // 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.
+ #define GDK_META_MASK 0

Cursors, too, have been a constant source of pleasure. The main difficulty
is that a GdkWindow inherits a cursor if the programmer sets a new cursor
- for the parent. To prevent this from doing too much harm, I use idle time
- to set the cursor over and over again, starting from the toplevel windows
- and ending with the youngest generation (speaking of parent and child windows).
+ for the parent. To prevent this from doing too much harm, SetCursor calls
+ GTKUpdateCursor, which will recursively re-set the cursors of all child windows.
Also don't forget that cursors (like much else) are connected to GdkWindows,
not GtkWidgets and that the "window" field of a GtkWidget might very well
point to the GdkWindow of the parent widget (-> "window-less widget") and
that the two obviously have very different meanings.
