//With a Callback function:
//************************

function EnumFontClBack(var lp: TEnumLogFont;
  var tm: TNewTextMetric;
  dwType: DWORD;
  lpData: lParam): Integer; stdcall;
begin
  
Result := 1;
  with TForm1(lpData), Combobox1 do
  begin
    
Items.Add(lp.elfLogFont.lfFaceName);
  end;
end;


procedure TForm1.FormShow(Sender: TObject);
begin
  
EnumFontFamilies(Canvas.Handle, nil, @EnumFontClBack, Integer(Self));
end;

procedure TForm1.ComboBox1Change(Sender: TObject);
begin
  
label1.Font.Name := Combobox1.Text;
end;


// Easier Way:
//*****************************************

{
 To show the items in the corresponding font
 The Style of the Listbox should be lbOwnerDrawVariable
}
 
 
procedure TForm1.ListBox1DrawItem(Control: TWinControl; Index: Integer;
  Rect: TRect; State: TOwnerDrawState);
begin
  with 
ListBox1 do
  begin
    
Canvas.fillrect(rect);
    Canvas.Font.Style := [fsbold];
    Canvas.Font.Name  := Listbox1.Items[Index];
    Canvas.textout(rect.Left, rect.Top, Listbox1.Items[Index]);
  end;
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
  
ComboBox1.Items := Screen.Fonts;
end;

procedure TForm1.ComboBox1Change(Sender: TObject);
begin
  
label1.Font.Name := ComboBox1.Items[ComboBox1.ItemIndex];
end;
