Hi Thomas,
Fons will answer this part.

TButton::SetMethod expects a string that can be executed via the
interpreter.
Below, you will find an example (from Atlfast) illustrating how to call
class member functions with parameters. The string is passed to teh
constructor,
but it also applies to SetMethod.

TButton *button;
char *but1 = "gATLFast->Display()->ShowNextEvent(1)";
button = new TButton("Next",but1,x0,y-dbutton,x1,y);
button->SetFillColor(38);
button->Draw();
y -= dbutton +dy;
char *but2 = "gATLFast->Display()->ShowNextEvent(-1)";
button = new TButton("Previous",but2,x0,y-dbutton,x1,y);
button->SetFillColor(38);
button->Draw();
y -= dbutton +dy;
char *but3 = "gATLFast->Display()->SetView(90,-90)";
button = new TButton("Top View",but3,x0,y-dbutton,x1,y);
button->SetFillColor(butcolor);
button->Draw();
y -= dbutton +dy;
char *but4 = "gATLFast->Display()->SetView(90,0)";
button = new TButton("Side View",but4,x0,y-dbutton,x1,y);
button->SetFillColor(butcolor);
button->Draw();
y -= dbutton +dy;
char *but5 = "gATLFast->Display()->SetView(0,-90)";
button = new TButton("Front View",but5,x0,y-dbutton,x1,y);
button->SetFillColor(butcolor);
button->Draw();
y -= dbutton +dy;
char *but6 = "gATLFast->Display()->DrawAllViews()";
button = new TButton("All Views",but6,x0,y-dbutton,x1,y);
button->SetFillColor(butcolor);
button->Draw();
y -= dbutton +dy;
char *but7 = "gATLFast->Display()->DrawViewGL()";
button = new TButton("OpenGL",but7,x0,y-dbutton,x1,y);
button->SetFillColor(38);
button->Draw();
y -= dbutton +dy;
char *but8 = "gATLFast->Display()->DrawViewX3D()";
button = new TButton("X3D",but8,x0,y-dbutton,x1,y);
button->SetFillColor(38);
button->Draw();
