Standalone ROOT application doesn’t terminate upon closing a canvas - root-framework

Question

I’m making a standalone ROOT application which should terminate upon closing a canvas. The following is my experimental code.
#include "TROOT.h"
#include "TApplication.h"
#include "TCanvas.h"
int main(){
TApplication *myapp=new TApplication("myapp",0,0);
TCanvas *c1 =new TCanvas("c1","Canvas Test",800,800);
c1->Connect("TCanvas", "Closed()", "TApplication",gApplication, "Terminate()");
myapp->Run();
return 0;
}
The code compiles without any warnings. The canvas opens when I run it. But when I close the the canvas, application doesn’t terminate and the terminal doesn’t prompt. Any suggestions ?
_ROOT Version: 6.20
_Platform: Ubuntu 20.04
_Compiler: g++

Thanks to #bellenot from root-forum for providing the following solution. Apparently, for ROOT 6 & above, This should be done with a TRootCanvas object.
#include "TROOT.h"
#include "TApplication.h"
#include "TCanvas.h"
#include "TRootCanvas.h"
int main()
{
TApplication *myapp = new TApplication("myapp", 0, 0);
TCanvas *c1 = new TCanvas("c1","Canvas Test",800,800);
TRootCanvas *rc = (TRootCanvas *)c1->GetCanvasImp();
rc->Connect("CloseWindow()", "TApplication", gApplication, "Terminate()");
myapp->Run();
return 0;
}
