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:

• several trees may be opened in the same session;
• branches and leaves can be easily browsed or scanned;
• fast drawing of branch expressions by double-clicking;
• new variables/selections easy to compose with the built-in editor;
• histograms can be composed by dragging leaves or user-defined expressions to X, Y and Z axis items;
• the tree entries to be processed can be selected with a double slider;
• selections can be defined and activated by dragging them to the 'Cut' item;
• all expressions can be aliased and aliases can be used in composing others;
• input/output event lists easy to handle;
• menu with histogram drawing options;
• user commands may be executed within the viewer and the current command can be echoed;
• current 'Draw' event loop is reflected by a progress bar and may be interrupted by the user;
• all widgets have self-explaining tool tips and/or context menus;
• expressions/leaves can be dragged to a 'scan box' and scanned by double-clicking this item. The result can be redirected to an ASCII file;

The layout has the following items:

• a menu bar with entries : File, Edit, Run, Options and Help;
• a toolbar in the upper part where you can issue user commands, change the drawing option and the histogram name, three check buttons Hist, Rec and Scan.HIST toggles histogram drawing mode, REC enables recording of the last command issued and SCAN enables redirecting of TTree::Scan command in an ASCII file (see -Scanning expressions-);
• a button bar in the lower part with : buttons DRAW/STOP that issue histogram drawing and stop the current command respectively, two text widgets where input and output event lists can be specified, a message box and a RESET button on the right that clear edited expression content (see Editing...)
• a tree-type list on the main left panel where you can select among trees or branches. The tree/branch will be detailed in the right panel. Mapped trees are provided with context menus, activated by right-clicking;
• a view-type list on the right panel. The first column contain X, Y and Z expression items, an optional cut and ten optional editable expressions. Expressions and leaf-type items can be dragged or deleted. A right click on the list-box or item activates context menus.

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 :

• you can write C expressions made of leaf names by hand or you can insert any item from the right panel by clicking on it (recommandable);
• you can click on other expressions/leaves to paste them in the editor;
• you should write the item alias by hand since it not only make the expression meaningful, but it also highly improve the layout for big expressions
• you may redefine an old alias - the other expressions depending on it will be modified accordingly. An alias must not be the leading string of other aliases. When Draw commands are issued, the name of the corresponding histogram axes will become the aliases of the expressions.

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 :

• EmptyAll : clears the content of all expressions;
• ExecuteCommand : execute a ROOT command;
• MakeSelector : equivalent of TTree::MakeSelector();
• NewExpression : add an expression item in the right panel;
• Process : equivalent of TTree::Process();
• SaveSource : save the current session as a C++ macro;
• SetScanFileName : define a name for the file where TTree::Scan command is redirected when the <Scan> button is checked;
• SetTreeName : open a new tree with this name in the viewer;

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

Commands are :

• Draw : draw a histogram for this item;
• EditExpression : pops-up the expression editor;
• Empty : empty the name and alias of this item;
• RemoveItem : removes clicked item from the list;
• Scan : scan this expression;
• SetExpression : edit name and alias for this item by hand;

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\");

   Supposing you have the tree MyTree in the file MyFile, you can do :

   root [1] TFile file("Myfile");
   root [2] new TTreeViewer("Mytree");

   or :

   root [2] TTreeViewer *tv = new TTreeViewer();
   root [3] tv->SetTreeName("Mytree");

The HISTOGRAM and OPTION boxes

As explained before, in the top bar, there is the "Histogram" box, prepopulated with the string "htemp", which will be the variable name where the drawn histogram will be stored. You can modify it to specify e.g. a specific 2D binning "htemp(100,0,10, 20,0,5)", in the same way that you would do it when calling TTree::Draw ( "x >> htemp(...)" ). Likewise, there is the "Option" box, where you can specify drawing options such as "SAME", "COLZ", etc. In fact, once you click on the Draw icon, the resulting behind-the-scenes executed command will be added to the ROOT history. You can go back to the command line and press arrow-up, to be able to edit it further if you prefer the command line rather than the GUI.

Comparing different cuts

It's a common use case to define different cuts on your data and compare them in the same canvas. To do so, define an expression e1 and e2 by double clicking on the empty "E<>" icons. Drag-and-drop e1 into the scissors icon, click then on the Draw icon. Then, add the "same" to the "Option" box, and change "htemp" to "htemp2", finally drag-and-drop e2 to the scissors, and click on the Draw icon again. Finally, right click on the resulting histogram (htemp2), choose "DrawPanel" and change the color to make it distinguishable. You can also define, directly by double-clicking on the scissors icons, or by generating a third expression e3, more complex cuts such as (~e1) && (~e2), or (~e1) || !(~e2). Parentheses are important.

Enumerator

kOnlyPrepStep

Used to request that the class specific implementation of TObject::Write just prepare the objects to be ready to be written but do not actually write them into the TBuffer. This is just for example by TBufferMerger to request that the TTree inside the file calls TTree::FlushBaskets (outside of the merging lock) and TBufferMerger will later ask for the write (inside the merging lock). To take advantage of this feature the class needs to overload TObject::Write and use this enum value accordingly. (See TTree::Write and TObject::Write) Do not use, this feature will be migrate to the Merge function (See TClass and TTree::Merge)

Member Function Documentation

AbstractMethod()

void TObject::AbstractMethod ( const char * method ) const

inherited

Call this function within a function that you don't want to define as purely virtual, in order not to force all users deriving from that class to implement that maybe (on their side) unused function; but at the same time, emit a run-time warning if they try to call it, telling that it is not implemented in the derived class: action must thus be taken on the user side to override it.

In other word, this method acts as a "runtime purely virtual" warning instead of a "compiler purely virtual" error.

Warning

This interface is a legacy function that is no longer recommended to be used by new development code.

Note

The name "AbstractMethod" does not imply that it's an abstract method in the strict C++ sense.

Definition at line 1149 of file TObject.cxx.

Activate()

virtual void TGFrame::Activate ( Bool_t )

inlinevirtualinherited

Reimplemented in TGLBEntry, TGLVEntry, TGPopupMenu, and TGTreeLBEntry.

Definition at line 212 of file TGFrame.h.

ActivateButtons()

		bool	previous,
		bool	next,
		bool	last )

AddFrame()

void TGCompositeFrame::AddFrame ( TGFrame * f, TGLayoutHints * l = nullptr )

virtualinherited

Add frame to the composite frame using the specified layout hints.

If no hints are specified default hints TGLayoutHints(kLHintsNormal,0,0,0,0) will be used. Most of the time, however, you will want to provide specific hints. User specified hints can be reused many times and need to be destroyed by the user. The added frames cannot not be added to different composite frames but still need to be deleted by the user.

Reimplemented in TGDockableFrame, TGFileContainer, TGPack, and TGSplitFrame.

Definition at line 1109 of file TGFrame.cxx.

AddInput()

void TGFrame::AddInput ( UInt_t emask )

CheckedHash()

ULong_t TObject::CheckedHash ( )

inlineinherited

Check and record whether this class has a consistent Hash/RecursiveRemove setup (*) and then return the regular Hash value for this object.

The intent is for this routine to be called instead of directly calling the function Hash during "insert" operations. See TObject::HasInconsistenTObjectHash();

(*) The setup is consistent when all classes in the class hierarchy that overload TObject::Hash do call ROOT::CallRecursiveRemoveIfNeeded in their destructor. i.e. it is safe to call the Hash virtual function during the RecursiveRemove operation.

Clone()

TObject * TObject::Clone ( const char * newname = "" ) const

virtualinherited

Make a clone of an object using the Streamer facility.

If the object derives from TNamed, this function is called by TNamed::Clone. TNamed::Clone uses the optional argument to set a new name to the newly created object.

If the object class has a DirectoryAutoAdd function, it will be called at the end of the function with the parameter gDirectory. This usually means that the object will be appended to the current ROOT directory.

Disconnect() [3/3]

Bool_t TQObject::Disconnect ( TQObject * sender, const char * signal = nullptr, void * receiver = nullptr, const char * slot = nullptr )

staticinherited

Disconnects signal in object sender from slot_method in object receiver.

For objects derived from TQObject signal-slot connection is removed when either of the objects involved are destroyed.

Disconnect() is typically used in three ways, as the following examples shows:

• Disconnect everything connected to an object's signals:

  Disconnect(myObject);

• Disconnect everything connected to a signal:

  Disconnect(myObject, "mySignal()");

• Disconnect a specific receiver:

  Disconnect(myObject, 0, myReceiver, 0);

0 may be used as a wildcard in three of the four arguments, meaning "any signal", "any receiving object" or "any slot in the receiving object", respectively.

The sender has no default and may never be 0 (you cannot disconnect signals from more than one object).

If signal is 0, it disconnects receiver and slot_method from any signal. If not, only the specified signal is disconnected.

If receiver is 0, it disconnects anything connected to signal. If not, slots in objects other than receiver are not disconnected

If slot_method is 0, it disconnects anything that is connected to receiver. If not, only slots named slot_method will be disconnected, and all other slots are left alone. The slot_method must be 0 if receiver is left out, so you cannot disconnect a specifically-named slot on all objects.

Return true is the type of this object is known to have an inconsistent setup for Hash and RecursiveRemove (i.e.

missing call to RecursiveRemove in destructor).

Note: Since the consistency is only tested for during inserts, this routine will return true for object that have never been inserted whether or not they have a consistent setup. This has no negative side-effect as searching for the object with the right or wrong Hash will always yield a not-found answer (Since anyway no hash can be guaranteed unique, there is always a check)

Turn on automatic cleanup of child frames in dtor.

Attention! Hierarchical cleaning is dangerous and must be used with caution. There are many GUI components (in ROOT and in user code) which do not use Clean method in destructor ("custom deallocation"). Adding such component to GUI container which is using hierarchical cleaning will produce seg. violation when container is deleted. The reason is double deletion: first when Clean method is invoked, then at "custom deallocation". We are going to correct all ROOT code to make it to be consistent with hierarchical cleaning scheme.

Write() [2/2]

Int_t TObject::Write ( const char * name = nullptr, Int_t option = 0, Int_t bufsize = 0 ) const

virtualinherited

Write this object to the current directory.

The data structure corresponding to this object is serialized. The corresponding buffer is written to the current directory with an associated key with name "name".

Writing an object to a file involves the following steps:

• Creation of a support TKey object in the current directory. The TKey object creates a TBuffer object.
• The TBuffer object is filled via the class::Streamer function.
• If the file is compressed (default) a second buffer is created to hold the compressed buffer.
• Reservation of the corresponding space in the file by looking in the TFree list of free blocks of the file.
• The buffer is written to the file.

Bufsize can be given to force a given buffer size to write this object. By default, the buffersize will be taken from the average buffer size of all objects written to the current file so far.

If a name is specified, it will be the name of the key. If name is not given, the name of the key will be the name as returned by GetName().

The option can be a combination of: kSingleKey, kOverwrite or kWriteDelete Using the kOverwrite option a previous key with the same name is overwritten. The previous key is deleted before writing the new object. Using the kWriteDelete option a previous key with the same name is deleted only after the new object has been written. This option is safer than kOverwrite but it is slower. NOTE: Neither kOverwrite nor kWriteDelete reduces the size of a TFile– the space is simply freed up to be overwritten; in the case of a TTree, it is more complicated. If one opens a TTree, appends some entries, then writes it out, the behaviour is effectively the same. If, however, one creates a new TTree and writes it out in this way, only the metadata is replaced, effectively making the old data invisible without deleting it. TTree::Delete() can be used to mark all disk space occupied by a TTree as free before overwriting its metadata this way. The kSingleKey option is only used by TCollection::Write() to write a container with a single key instead of each object in the container with its own key.

An object is read from the file into memory via TKey::Read() or via TObject::Read().

The function returns the total number of bytes written to the file. It returns 0 if the object cannot be written.

Reimplemented in TBuffer, TCollection, TDirectory, TDirectoryFile, TFile, TMap, TParallelMergingFile, TSQLFile, TTree, and TXMLFile.
