Detailed Description

LoupOnPad, a class to Loupe on a Pad in a Canvas with many pads in it.

It uses keyboard keys to play play with the Loupe. To activate a Loupe on the current Canvas:

RunLoupeOnPad();

or alternatively, if the pointer on the canvas is known

{
    //create a canvas and divide it in 20 x 20 pads
    Int_t nb_x = 20, nb_y = 20;
 
    TCanvas *c1 = new TCanvas("c1","c1",10,10,800,800);
 
    c1->Divide(nb_x,nb_y,0,0);
    Int_t ipad = 0;
    for (Int_t i=0;i<nb_x;i++) {
        for (Int_t j=0;j<nb_y;j++) {
            ipad++;
            c1->cd(ipad);
 
            TH1F *h = new TH1F(Form("h%d_%d",i,j),"test",100,-3,3);
            h->FillRandom("gaus",(ipad+1)*3);
            h->Draw();
            TH1F *h2 = new TH1F(Form("hh%d_%d",i,j),"test",100,-3,3);
            h2->SetFillColor(kRed);
            h2->FillRandom("gaus",(ipad+1)*3);
            h2->Draw("same");
        }
    }
 
    loupe = new LoupeOnPad(c1);
