TTreeViewer Class Reference

A graphic user interface designed to handle ROOT trees and to take advantage of TTree class features.

It uses ROOT native GUI widgets adapted for "drag and drop" functionality. in the same session.

The following capabilities are making the viewer a helpful tool for analysis:

The layout has the following items:

Opening a new tree and saving a session :

To open a new tree in the viewer use <File/Open tree file> menu The content of the file (keys) will be listed. Use <SetTreeName> function from the context menu of the right panel, entering a tree name among those listed.

To save the current session, use <File/Save> menu or the <SaveSource> function from the context menu of the right panel (to specify the name of the file - name.C)

To open a previously saved session for the tree MyTree, first open MyTree in the browser, then use <File/Open session> menu.

Dragging items:

Items that can be dragged from the list in the right : expressions and leaves. Dragging an item and dropping to another will copy the content of first to the last (leaf->expression, expression->expression). Items far to the right side of the list can be easily dragged to the left (where expressions are placed) by dragging them to the left at least 10 pixels.

Editing expressions:

Any editable expression from the right panel has two components : a true name (that will be used when TTree::Draw() commands are issued) and an alias. The visible name is the alias. Aliases of user defined expressions have a leading ~ and may be used in new expressions. Expressions containing boolean operators have a specific icon and may be dragged to the active cut (scissors item) position.

The expression editor can be activated by double-clicking empty expression, using <EditExpression> from the selected expression context menu or using <Edit/Expression> menu.

The editor will pop-up in the left part, but it can be moved. The editor usage is the following :

User commands can be issued directly from the textbox labeled "Command" from the upper-left toolbar by typing and pressing Enter at the end.

Another way is from the right panel context menu : ExecuteCommand. All commands can be interrupted at any time by pressing the STOP button from the bottom-left You can toggle recording of the current command in the history file by checking the Rec button from the top-right

Context menus

You can activate context menus by right-clicking on items or inside the right panel.

Context menus for mapped items from the left tree-type list : The items from the left that are provided with context menus are tree and branch items. You can directly activate the MENU marked methods of TTree from this menu.

Context menu for the right panel:

A general context menu is activated if the user right-clicks the right panel.

Commands are :

A specific context menu is activated if expressions/leaves are right-clicked.

Commands are :

Starting the viewer

  1. From the TBrowser: Select a tree in the TBrowser, then call the StartViewer() method from its context menu (right-click on the tree).
  2. From the command line: Start a ROOT session in the directory where you have your tree. You will need first to load the library for TTreeViewer and optionally other libraries for user defined classes (you can do this later in the session) :
    root [0] gSystem->Load(\"TTreeViewer\");
    R__EXTERN TSystem * gSystem
    Definition: TSystem.h:540
    virtual int Load(const char *module, const char *entry="", Bool_t system=kFALSE)
    Load a shared library.
    Definition: TSystem.cxx:1843
    Supposing you have the tree MyTree in the file MyFile, you can do :
    root [1] TFile file("Myfile");
    root [2] new TTreeViewer("Mytree");
    A ROOT file is a suite of consecutive data records (TKey instances) with a well defined format.
    Definition: TFile.h:48
    TTreeViewer(const char *treeName=0)
    TTreeViewer default constructor.
    Definition: file.py:1
    or :
    root [2] TTreeViewer *tv = new TTreeViewer();
    root [3] tv->SetTreeName("Mytree");
