Convert C# to C++/CLI Windows Forms

Question

I want to display a vertical ControlTab with horizontal text. I have found the following C# code. Please help me to translate this for using with C++/CLI Windows Forms.

using System;  
using System.Drawing;  
using System.Windows.Forms;  
  
class VerticalTabControl : TabControl {  
    public VerticalTabControl() {  
        this.Alignment = TabAlignment.Right;  
        this.DrawMode = TabDrawMode.OwnerDrawFixed;  
        this.SizeMode = TabSizeMode.Fixed;  
        this.ItemSize = new Size(this.Font.Height * 3 / 2, 75);  
    }  
    public override Font Font {  
        get { return base.Font;  }  
        set {  
            base.Font = value;  
    this.ItemSize = new Size(value.Height * 3 / 2, base.ItemSize.Height);  
    }  
    }  
        protected override void OnDrawItem(DrawItemEventArgs e) {  
        using (var _textBrush = new SolidBrush(this.ForeColor)) {  
            TabPage _tabPage = this.TabPages[e.Index];  
            Rectangle _tabBounds = this.GetTabRect(e.Index);  
  
            if (e.State != DrawItemState.Selected) e.DrawBackground();  
            else {  
                using (var brush = new System.Drawing.Drawing2D.LinearGradientBrush(e.Bounds, Color.White, Color.LightGray, 90f)) {  
                    e.Graphics.FillRectangle(brush, e.Bounds);  
                }  
            }  
  
            StringFormat _stringFlags = new StringFormat();  
            _stringFlags.Alignment = StringAlignment.Center;  
            _stringFlags.LineAlignment = StringAlignment.Center;  
            e.Graphics.DrawString(_tabPage.Text, this.Font, _textBrush, _tabBounds, new StringFormat(_stringFlags));  
        }  
    }  
}

Check this class:

using namespace System;  
using namespace System::Drawing;  
using namespace System::Windows::Forms;  
  
namespace MyNamespace  
{  
    public ref class VerticalTabControl : public TabControl  
    {  
        using base = TabControl;  
  
    public:  
  
        VerticalTabControl( )  
        {  
            this->Alignment = TabAlignment::Right;  
            this->DrawMode = TabDrawMode::OwnerDrawFixed;  
            this->SizeMode = TabSizeMode::Fixed;  
            this->ItemSize = System::Drawing::Size( this->Font->Height * 3 / 2, 75 );  
        }  
  
        property System::Drawing::Font^ Font  
        {  
            virtual System::Drawing::Font^ get( ) override  
            {  
                return base::Font;  
            }  
  
            virtual void set( System::Drawing::Font^ value ) override  
            {  
                base::Font = value;  
                this->ItemSize = System::Drawing::Size( value->Height * 3 / 2, base::ItemSize.Height );  
            }  
        }  
  
    protected:  
  
        virtual void OnDrawItem( DrawItemEventArgs^ e ) override  
        {  
            SolidBrush _textBrush( ForeColor );  
  
            TabPage^ _tabPage = TabPages[e->Index];  
            Rectangle _tabBounds = GetTabRect( e->Index );  
  
            if( e->State != DrawItemState::Selected )  
            {  
                e->DrawBackground( );  
            }  
            else  
            {  
                Drawing2D::LinearGradientBrush brush( e->Bounds, Color::White, Color::LightGray, 90.0 );  
  
                e->Graphics->FillRectangle( % brush, e->Bounds );  
            }  
  
            StringFormat _stringFlags;  
            _stringFlags.Alignment = StringAlignment::Center;  
            _stringFlags.LineAlignment = StringAlignment::Center;  
            e->Graphics->DrawString( _tabPage->Text, Font, % _textBrush, _tabBounds, gcnew StringFormat( % _stringFlags ) );  
        }  
    };  
}

I started with:

    using namespace System;  
    using namespace System::Drawing;  
    using namespace System::Windows::Forms;  
      
    ref class VerticalTabControl: public System::Windows::Forms::TabControl {  
      public: VerticalTabControl() {  
       this->Alignment = TabAlignment::Right;  
       this->DrawMode = TabDrawMode::OwnerDrawFixed;  
       this->SizeMode = TabSizeMode::Fixed;  
       this->ItemSize = System::Drawing::Size(this->Font->Height*3/2, 75);  
      }  
    };  

But next I couldn't understand.
