Программный код на Delphi для создания приложения VCL, отображающего иерархию классов в библиотеке VCL.

В этом коде создается форма с деревом (TreeView), прогрессбаром (ProgressBar) и кнопками (Button). Кнопка Button1 запускает процесс создания дерева классов, начиная от TObject. Каждый класс добавляется в дерево как дочерний элемент для родительского класса.

Кнопка Button2 позволяет сортировать дерево по имени класса.

Когда пользователь выбирает узел в дереве, информация о выбранном классе отображается в текстовом поле (Memo).

Вот полный код формы:

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, TreeView, StdCtrls, ProgressBar, Buttons, Memo;

type
  TForm1 = class(TForm)
    TreeView1: TTreeView;
    ProgressBar1: TProgressBar;
    Button1: TButton;
    Button2: TButton;
    Memo1: TMemo;
    procedure Button1Click(Sender: TObject);
    procedure TreeView1Change(Sender: TObject; Node: TTreeNode);
    procedure Button2Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

  begin
    AddClass(ClassArray[I]);
    ProgressBar1.Position := I;
  end;
  Beep;
  ShowMessage('Tree Completed');
  Button2.Enabled := True;
  Button1.Enabled := False;
end;

procedure TForm1.AddClass(NewClass: TClass): TTreeNode;
var
  ParentNode: TTreeNode;
begin
  Result := GetNode(NewClass);
  if Result = nil then
  begin
    // look for the parent (eventually adding it)
    ParentNode := AddClass(NewClass.ClassParent);
    // add the new class
    Result := TreeView1.Items.AddChildObject(ParentNode, NewClass.ClassName, Pointer(NewClass));
  end;
end;

  // find the node in the tree
  Node1 := TreeView1.Items.GetFirstNode;
  while Node1 <> nil do

    begin
      Result := Node1;
      Exit;
    end;

  end;
end;

  Memo1.Lines.Add('=== Parent classes ===');
  while MyClass.ClassParent <> nil do
  begin
    MyClass := MyClass.ClassParent;
    Memo1.Lines.Add(MyClass.ClassName);
  end;
end;

begin
  Screen.Cursor := crHourglass;
  TreeView1.SortType := stText;
  Screen.Cursor := crDefault;
  Button2.Enabled := False;
end;

end.

This is a Delphi project that creates a VCL Hierarchy Viewer, which displays the hierarchy of classes in the Delphi library. The project consists of a form with a tree view control, a memo control, and three buttons. Here's a breakdown of the code: 1. T
