10 // This macro generates a Controlbar panel:
11 // begin_html <P ALIGN=CENTER> <IMG SRC="gif/PadControlPanel.gif" ></P> end_html
12 //
13 // To execute an item, click with the left mouse button.
14 //
15 // Just start this macro wheneven you want:
16 //
17 // From Root/Cint macro:
18 // --------------------
19 // .x PadControlPanel.C
20 // .L PadControlPanel.C
21 // or
22 // gROOT->LoadMacro("PadControlPanel.C");
23 //
24 // From the compiled C++ code:
25 // --------------------
26 // gROOT->LoadMacro("PadControlPanel.C");
27 //
28 // After that one may "click" <4 views> button to get from the single "view"
29 // the expanded view as follows:
30 // begin_html <P ALIGN=CENTER> <IMG SRC="gif/FourStarView.gif" ></P> end_html
31 // To cutomize the default bar the dirived class with the custom void UserBar()
32 // method can be done.
33 // TGButtonGroup *Bar(){ return fBar;}
34 // method can be used.
35 //
36 // Example:
37 // TGButtonGroup *myBar = __aa__.Bar();
38 // myBar->AddButton("My custom","printf(\"here is my custom action\n\");","To add your own action replace the second parameter");
39 //
40 // Note: If you don't like what it does make your private copy
41 // ==== change it with your favorite text editor and load it right
42 // away.
43 // NO EXTRA STEP like : compilation, linking, loading required
44 //
