12 /** \class TTreeViewer
13 A graphic user interface designed to handle ROOT trees and to take advantage of
14 TTree class features.
15 
16 It uses ROOT native GUI widgets adapted for "drag and drop" functionality.
17 in the same session.
18 
19 ### The following capabilities are making the viewer a helpful tool for analysis:
20 
21  - several trees may be opened in the same session;
22  - branches and leaves can be easily browsed or scanned;
23  - fast drawing of branch expressions by double-clicking;
24  - new variables/selections easy to compose with the built-in editor;
25  - histograms can be composed by dragging leaves or user-defined expressions
26  to X, Y and Z axis items;
27  - the tree entries to be processed can be selected with a double slider;
28  - selections can be defined and activated by dragging them to the 'Cut' item;
29  - all expressions can be aliased and aliases can be used in composing others;
30  - input/output event lists easy to handle;
31  - menu with histogram drawing options;
32  - user commands may be executed within the viewer and the current command
33  can be echoed;
34  - current 'Draw' event loop is reflected by a progress bar and may be
35  interrupted by the user;
36  - all widgets have self-explaining tool tips and/or context menus;
37  - expressions/leaves can be dragged to a 'scan box' and scanned by
38  double-clicking this item. The result can be redirected to an ASCII file;
39 
40 ### The layout has the following items:
41 
42  - a menu bar with entries : File, Edit, Run, Options and Help;
43  - a toolbar in the upper part where you can issue user commands, change
44  the drawing option and the histogram name, three check buttons Hist, Rec
45  and Scan.HIST toggles histogram drawing mode, REC enables recording of the
46  last command issued and SCAN enables redirecting of TTree::Scan command in
47  an ASCII file (see -Scanning expressions-);
48  - a button bar in the lower part with : buttons DRAW/STOP that issue histogram
49  drawing and stop the current command respectively, two text widgets where
50  input and output event lists can be specified, a message box and a RESET
51  button on the right that clear edited expression content (see Editing...)
52  - a tree-type list on the main left panel where you can select among trees or
53  branches. The tree/branch will be detailed in the right panel.
54  Mapped trees are provided with context menus, activated by right-clicking;
55  - a view-type list on the right panel. The first column contain X, Y and
56  Z expression items, an optional cut and ten optional editable expressions.
57  Expressions and leaf-type items can be dragged or deleted. A right click on
58  the list-box or item activates context menus.
59 
60 ### Opening a new tree and saving a session :
61 
62  To open a new tree in the viewer use `<File/Open tree file>` menu
63 The content of the file (keys) will be listed. Use `<SetTreeName>` function
64 from the context menu of the right panel, entering a tree name among those
65 listed.
66 
67  To save the current session, use `<File/Save>` menu or the `<SaveSource>`
68 function from the context menu of the right panel (to specify the name of the
69 file - name.C)
70 
71  To open a previously saved session for the tree MyTree, first open MyTree
72 in the browser, then use `<File/Open session>` menu.
73 
74 ### Dragging items:
75 
76 Items that can be dragged from the list in the right : expressions and
77 leaves. Dragging an item and dropping to another will copy the content of first
78 to the last (leaf->expression, expression->expression). Items far to the right
79 side of the list can be easily dragged to the left (where expressions are
80 placed) by dragging them to the left at least 10 pixels.
81 
82 ### Editing expressions:
83 
84  Any editable expression from the right panel has two components : a
85 true name (that will be used when TTree::Draw() commands are issued) and an
86 alias. The visible name is the alias. Aliases of user defined expressions have
87 a leading ~ and may be used in new expressions. Expressions containing boolean
88 operators have a specific icon and may be dragged to the active cut (scissors
89 item) position.
90 
91  The expression editor can be activated by double-clicking empty expression,
92 using `<EditExpression>` from the selected expression context menu or using
93 `<Edit/Expression>` menu.
94 
95  The editor will pop-up in the left part, but it can be moved.
96 The editor usage is the following :
97 
98  - you can write C expressions made of leaf names by hand or you can insert
99  any item from the right panel by clicking on it (recommandable);
100  - you can click on other expressions/leaves to paste them in the editor;
101  - you should write the item alias by hand since it not only make the
102  expression meaningful, but it also highly improve the layout for big
103  expressions
104  - you may redefine an old alias - the other expressions depending on it will
105  be modified accordingly. An alias must not be the leading string of other
106  aliases. When Draw commands are issued, the name of the corresponding
107  histogram axes will become the aliases of the expressions.
108 
109 User commands can be issued directly from the textbox labeled "Command"
110 from the upper-left toolbar by typing and pressing Enter at the end.
111 
112  Another way is from the right panel context menu : ExecuteCommand.
113 All commands can be interrupted at any time by pressing the STOP button
114 from the bottom-left
115 You can toggle recording of the current command in the history file by
116 checking the Rec button from the top-right
117 
118 ### Context menus
119 
120  You can activate context menus by right-clicking on items or inside the
121 right panel.
122 
123 Context menus for mapped items from the left tree-type list :
124  The items from the left that are provided with context menus are tree and
125 branch items. You can directly activate the *MENU* marked methods of TTree
126 from this menu.
127 
128 Context menu for the right panel:
129 
130  A general context menu is activated if the user right-clicks the right panel.
131 
132  Commands are :
133  - EmptyAll : clears the content of all expressions;
134  - ExecuteCommand : execute a ROOT command;
135  - MakeSelector : equivalent of TTree::MakeSelector();
136  - NewExpression : add an expression item in the right panel;
137  - Process : equivalent of TTree::Process();
138  - SaveSource : save the current session as a C++ macro;
139  - SetScanFileName : define a name for the file where TTree::Scan command
140  is redirected when the `<Scan>` button is checked;
141  - SetTreeName : open a new tree with this name in the viewer;
142 
143  A specific context menu is activated if expressions/leaves are right-clicked.
144 
145  Commands are :
146  - Draw : draw a histogram for this item;
147  - EditExpression : pops-up the expression editor;
148  - Empty : empty the name and alias of this item;
149  - RemoveItem : removes clicked item from the list;
150  - Scan : scan this expression;
151  - SetExpression : edit name and alias for this item by hand;
152 
153 Starting the viewer
154 
155  1. From the TBrowser: Select a tree in the TBrowser, then call the
156  StartViewer() method from its context menu (right-click on the tree).
157  2. From the command line: Start a ROOT session in the directory where you have
158  your tree. You will need first to load the library for TTreeViewer and
159  optionally other libraries for user defined classes (you can do this later in
160  the session) :
161 ~~~ {.cpp}
162  root [0] gSystem->Load(\"TTreeViewer\");
163 ~~~
164 Supposing you have the tree MyTree in the file MyFile, you can do :
165 ~~~ {.cpp}
166  root [1] TFile file("Myfile");
167  root [2] new TTreeViewer("Mytree");
168 ~~~
169 or :
170 ~~~ {.cpp}
171  root [2] TTreeViewer *tv = new TTreeViewer();
172  root [3] tv->SetTreeName("Mytree");
173 ~~~
