Using dictionary to find/call a method of a class

ROOT
1

Hi all,

is it possible to use ROOT dictionary to find a class method by name and then call it ?

I mean, using TClass, then getting from it the method knowing its name (i.e. SetMarkerColor) and then
call the method to set some property (i.e. kRed).

I can find the method doing:

TH1F* h = new TH1F(“h”,"",1,0,1);
TClass* c = h->IsA();
TMethod *m = c->GetMethodAllAny(“SetMarkerColor”);

but then ? how do i execute the method setting the marker color ?

best,
Max

Hi Max,

sorry for the long delay, the post was somehow missed.
You can use TMethodCall docs.python.org/2/library/funct … ml#getattr .
