Class explorer

Is there a feature in the Lazarus IDE to display Class inheritance?

If I have TParentClass, can I get information all descendant classes like below?

Code: Pascal  [Select][+][-]

1. TParentClass=class;
2.    TChild1Class=class(TParentClass);
3.        TGrandChild1Class1=class(TChild1Class)
4.        TGrandChild2Class1=class(TChild1Class)
5.    TChild2Class=class(TParentClass);
6.        TGrandChild1Class2=class(TChild2Class)
7.        TGrandChild2Class2=class(TChild2Class)
8.

There's only class hierarchy for Components (View -> Components). I don't know any for project itself.

Hi
Dunno about IDE, but you can traverse the class hierarchy backwards from e.g.: TGrandChild2Class2 via the ClassParent function of TObject, yourself.

I use Code Explorer. Not very good, hope it will be improved in the future.

See the attached screenshot below. There we can see TgiButton is a child class of TgiLabel. And Both TgiRectangle and TgiLabel are child classes of TgiItem.

Traverse backward is easy, we can see the parent class in the class declaration.

For documentation purposes I wrote myself the attached ClassHierarchy application which contains an LvlGraphControl to list the hierarchical relation between classes added. Specify the classes in the AddControls method, but don't forget to add the units of the classes to the uses clause. Note that the application assumes that the component icons are found in the images/components folder of the Lazarus installation (for more general locations this part of the application must be extended).

I know only ModelMaker Code Explorer (MMX) for delphi can do this . So, view the code in delphi.
