Exception
 \_ error.XError
     \_ error.BadRequest
     \_ error.BadValue
     \_ error.BadAtom
     \_ error.BadMatch
     \_ error.BadAccess
     \_ error.BadAlloc
     \_ error.BadName
     \_ error.BadLength
     \_ error.BadImplementation
     \_ error.XResourceError
         \_ error.BadWindow
         \_ error.BadPixmap
         \_ error.BadCursor
         \_ error.BadFont
         \_ error.BadDrawable
         \_ error.BadColor
