Draw inheritance tree and their relations for a list of classes.

The following options are supported

Direct inheritance (default)
Multiple inheritance
Composition
References by data members and member functions
References from Code

The list of classes is specified:

either in the TClassTree constructor as a second argument
or the parameter to TClassTree::Draw

Note that the ClassTree viewer can also be started from the canvas pull down menu "Classes".

In the list of classes, class names are separated by a ":" wildcarding is supported. The following formats are supported, eg in TClassTree::Draw

Draw("ClassA")
- Draw inheritance tree for ClassA
- Show all classes referenced by ClassA
Draw("*ClassB")
- Draw inheritance tree for ClassB and all the classes deriving from ClassB
Draw(">ClassC")
- Draw inheritance tree for ClassC
- Show classes referencing ClassC
Draw("ClassD<")
- Draw inheritance tree for ClassD
- Show classes referenced by ClassD
- Show all classes referencing ClassD
Draw("Cla*")
- Draw inheritance tree for all classes with name starting with "Cla"
- Show classes referenced by these classes
Draw("ClassA:ClassB<")
- Draw inheritance tree for ClassA
- Show all classes referenced by ClassA
- Draw inheritance tree for ClassB
- Show classes referenced by ClassB
- Show all classes referencing ClassB

Example: Draw("TTree<")

Draw inheritance tree for the Root class TTree
Show all classes referenced by TTree
Show all classes using TTree

By default, only direct inheritance is drawn. Use TClassTree::ShowLinks(option) to show additional references

option = "H" to show links to embedded classes
option = "M" to show multiple inheritance
option = "R" to show pointers to other classes from data members
option = "C" to show classes used by the code(implementation) of a class

The following picture is produced directly by:

TClassTree ct("ct","*TH1")

TClassTree

Draw inheritance tree and their relations for a list of classes.

Definition: TClassTree.h:21

It shows all the classes derived from the base class TH1.

The TClassTree class uses the services of the class TPaveClass to show the class names. By clicking with the right mouse button in one TPaveClass object, one can invoke the following functions of TClassTree:

ShowLinks(option) with by default option = "HMR"
Draw(classes). By default the class drawn is the one being pointed
ShowClassesUsedBy(classes) (by default the pointed class)
ShowClassesUsing(classes) (by default the pointed class)

The following picture has been generated with the following statements

TClassTree tc1("tc1","TH1");

tc1.ShowLinks("HMR");

Note that in case of embedded classes or pointers to classes, the corresponding dashed lines or arrows respectively start in the TPaveClass object at an X position reflecting the position in the list of data members.

References by data members to other classes are show with a full red line
Multiple inheritance is shown with a dashed blue line
"Has a" relation is shown with a dotted cyan line
References from code is shown by a full green line

Use TClassTree::SetSourceDir to specify the search path for source files. By default the search path includes the $ROOTSYS directory, the current directory and the subdirectory src.

The first time TClassTree::Draw is invoked, all the classes in the current application are processed, including the parsing of the code to find all classes referenced by the include statements. This process may take a few seconds. The following commands will be much faster.

A TClassTree object may be saved in a Root file. This object can be processed later by a Root program that ignores the original classes. This interesting possibility allows to send the class structure of an application to a colleague who does not have your classes.

Example:

TFile f("myClasses.root","recreate")
TClassTree *ct = new TClassTree("ct","ATLF*")
ct->Write();

You can send at this point the file myClass.root to a colleague who can run the following Root basic session

TFile f("myClass.root"); //connect the file
tt.ls();                 //to list all classes and titles
tt.Draw("ATLFDisplay")   //show class ATLFDisplay with all its dependencies

At this point, one has still access to all the classes present in the original session and select any combination of these classes to be displayed.
