I've added the %operator tag to the bindings, just for wxPoint for
now. Since lua has only a limited subset of operators (no +=3D, ++, etc)
I've just made them into functions, which even if we wanted to
override the lua operators in the metatable we'd still use the
functions.
They take the same semantics as C++ class operator functions, just
prepend %operator to it.
operators["=3D"] =3D "op_assign"
operators["=3D=3D"] =3D "op_eq"
operators["!=3D"] =3D "op_ne"
operators["<"] =3D "op_lt"
operators[">"] =3D "op_gt"
operators["<=3D"] =3D "op_le"
operators[">=3D"] =3D "op_ge"
operators["|"] =3D "op_or"
operators["&"] =3D "op_and"
operators["||"] =3D "op_lor"
operators["&&"] =3D "op_land"
operators["!"] =3D "op_not"
operators["++"] =3D "op_inc"
operators["--"] =3D "op_dec"
operators["+"] =3D "op_add"
operators["-"] =3D "op_sub"
operators["*"] =3D "op_mul"
operators["/"] =3D "op_div"
operators["+=3D"] =3D "op_add_eq"
operators["-=3D"] =3D "op_sub_eq"
operators["*=3D"] =3D "op_mul_eq"
operators["/=3D"] =3D "op_div_sub"
operators["%=3D"] =3D "op_mod_sub"
operators["&=3D"] =3D "op_and_eq"
operators["|=3D"] =3D "op_or_eq"
operators["^=3D"] =3D "op_xor_eq"
For example:
a =3D wx.wxPoint(1,2)
b =3D wx.wxPoint(1,2)
print(a:op_eq(b))
b =3D wx.wxPoint(1,3)
print(a:op_eq(b))
c =3D wx.wxSize(3,3)
d =3D b:op_add_eq(c)
print(d:GetX(), d:GetY())
true
false
