Csharp Override Tool Tip Test

In Csharp Tool Tip Test I did a minimal test on tool tips. I wanted to customize it and found a thread on how to change it at MSDN Social: [1] and in it a class overrides the old tool tip class. It contains a font that is set in the constructor - here is what is looks like with an ugly font:

    public class MyTooltip : ToolTip
    {
        private Font m_font = null;

        public MyTooltip(Font font) : base()
        {
            m_font = font;

            this.OwnerDraw = true;
            this.Draw += new DrawToolTipEventHandler(OnDraw);
            this.Popup += new PopupEventHandler(OnPopup);
        }

        protected override void Dispose(bool disposing)
        {
            this.Draw -= new DrawToolTipEventHandler(OnDraw);
            this.Popup -= new PopupEventHandler(OnPopup);
            base.Dispose(disposing);
        }

        public new bool IsBalloon
        {
            set { ; }
            get { return base.IsBalloon; }
        }

        private void OnPopup(object sender, PopupEventArgs e)
        {
            SizeF size = e.AssociatedControl.CreateGraphics().MeasureString(this.GetToolTip(e.AssociatedControl), m_font);
            e.ToolTipSize = new Size(Convert.ToInt32(size.Width), Convert.ToInt32(size.Height));
        }

        private void OnDraw(object sender, DrawToolTipEventArgs e)
        {
            DrawToolTipEventArgs newArgs = new DrawToolTipEventArgs(e.Graphics,
                                                e.AssociatedWindow,
                                                e.AssociatedControl,
                                                e.Bounds,
                                                e.ToolTipText,
                                                this.BackColor,
                                                this.ForeColor,
                                                m_font);

            newArgs.DrawBackground();
            newArgs.DrawBorder();
            newArgs.DrawText(TextFormatFlags.TextBoxControl);
        }
    }

One really positive thing is that it integrates nicely into Microsoft Visual Studio:
