XKB and GDK both add "internal" bits to GdkModifierType. In C, this typically doesn't cause problems as bitfields are just integers, and there's no validation. However for bindings, it's normal to convert enumerations to "native" enumeration types, which don't support unknown bits. See bug 597292. https://bugzilla.gnome.org/show_bug.cgi?id=634994

|
|

|
|

* reserved values such as %GDK_MODIFIER_RESERVED_13_MASK. Your code
|
|
* should preserve and ignore them. You can use %GDK_MODIFIER_MASK to
