//
// This macro generates a Controlbar panel: 
// begin_html  <P ALIGN=CENTER> <IMG SRC="gif/EventControlPanel.gif" ></P> end_html
//
// To execute an item, click with the left mouse button.
//  
// Just start this macro wheneven you want:
//
//  From Root/Cint macro:
//  --------------------
//   .x EventControlPanel.C
//   .L EventControlPanel.C
// or
//   gROOT->LoadMacro("EventControlPanel.C");
//
//  From the compiled C++ code:
//  --------------------
//   gROOT->LoadMacro("EventControlPanel.C");
//
//  After that one may "click" <4 views> button to get from the single "view"
//  the expanded view as follows:
//  begin_html  <P ALIGN=CENTER> <IMG SRC="gif/FourStarView.gif" ></P> end_html
//  To cutomize the default bar the dirived class with the custom void UserBar()
//  method can be done.
//         TControlBar *Bar(){ return fBar;}  
//  method can be used.
//
//  Example:
//    TControlBar *myBar =   __aa__.Bar();
//     myBar->AddButton("My custom","printf(\"here is my custom action\n\");","To add your own action replace the second parameter"); 
//
//  Note:  If you don't like what it does make your private copy 
//  ====   change it with your favorite text editor and load it right
//         away.
//         NO EXTRA STEP like : compilation, linking, loading required 
//

//
//  PadControl panel is the set of the static methods to control 
//  TView of any "current" TPad with some "primitive"
//  operation:
