I am making a program where a bunch of root graphs are displayed on the screen. The problem is, after they are created, I couldn’t find a way to close them through the executable itself. This is my code:

void functions::graph(vector<vector<double> > input) {
    TApplication *myApp = new TApplication("myApp", 0, 0);



    int nPoints = input[0].size();
    vector<double> x(nPoints);
    for (int i = 0; i < nPoints; i++) {
        x[i] = i * 2.5e-9;
    }

    for (int j = 0; j < int(input.size()); j++) {

          vector<double> y = input[j];
          string canvasname = "c" + to_string(j);
          TCanvas *c1 = new TCanvas(canvasname.c_str(), "Graph", 200, 10, 600, 400);
          TGraph *graph = new TGraph(nPoints, &x[0], &y [0]);
 
          graph->Draw("ACP");
          c1->Draw();

          myApp->Run();

   

        }

}

Everything works fine until myApp->Run() part. It runs forever. I want the graph windows to terminate when a specific input is entered in the executable, “quit” for example . How do I achieve that?

myApp->Run(kTRUE); // canvas main menu -> File -> Quit ROOT
