Texmacs and SCIM Confliction

If you have both Texmacs and SCIM install in your Linux box, you may encounter this problem:
In Texmacs, if you click on the menu bar or toolbar, you will lose your keypoint input. I took me long time to realize it comes from the confliction of Texmacs and SCIM. Currently I don’t have a neat solution. The hack I am using is to restart SCIM (SCIM System Icon->Right Click->Exit), and then Texmacs will work normally. Just a tip for those who have the same problem.

[C++] function as template typename

In the process of implementing equation and optimization algorithms, I encounter the problem of templaterize the algorithm with function types. The functions can be normal C functions, or function classes. The final solution is like this:

template
class Evaluator {
public:
Evaluator(const Functor& f)
: f_(f) {
}
double eval(int x) {
return f_(x);
}
private:
Functor f_;
};

double f(double x) {
return x * x;
}

class F {
public:
double operator(double x) {
return x * x;
}
};

int main(int argc, char* argv[]) {
Evaluator fevaluator(f);
F f2;
Evaluator Fevaluator(f2);
cout << fevaluator.eval(2) << " " << Fevaluator.eval(2) << endl;
}
