Description
This works as expected:
#include <TH1F.h>
|
|
|
class MyTH1F : public TH1F |
{
|
public: |
using TH1F::TH1F;
|
};
|
|
|
int main() |
{
|
MyTH1F h("name", "title", 100, 0, 100); |
}
|
if I remove the using directive I get:
a.cpp:11:40: error: no matching function for call to 'MyTH1F::MyTH1F(const char [5], const char [6], int, int, int)' |
11 | MyTH1F h("name", "title", 100, 0, 100); |
| ^
|
a.cpp:3:7: note: candidate: 'MyTH1F::MyTH1F()' |
3 | class MyTH1F : public TH1F |
| ^~~~~~
|
a.cpp:3:7: note: candidate expects 0 arguments, 5 provided |
a.cpp:3:7: note: candidate: 'MyTH1F::MyTH1F(const MyTH1F&)' |
a.cpp:3:7: note: candidate expects 1 argument, 5 provided |
a.cpp:3:7: note: candidate: 'MyTH1F::MyTH1F(MyTH1F&&)' |
a.cpp:3:7: note: candidate expects 1 argument, 5 provided |
|
as expected.

The problem is if I do this:
import ROOT |
|
|
ROOT.gInterpreter.Declare(
|
""" |
class MyTH1F : public TH1F |
{
|
public: |
using TH1F::TH1F;
|
};
|
""") |
|
|
h = ROOT.MyTH1F("name", "title", 100, 0, 100) |
I get the same error as if the using directive were not present
TypeError: none of the 3 overloaded methods succeeded. Full details: |
