下面的代码示例设计用于 Windows 窗体,它需要 PaintEventArgse,这是 Paint 事件处理程序的参数。 该代码执行以下操作:

  • 创建纯红色画笔。

  • 创建一个矩形,该矩形绑定椭圆。

  • 填充屏幕上的省略号。

public:
   void FillEllipseRectangle( PaintEventArgs^ e )
   {
      // Create solid brush.
      SolidBrush^ redBrush = gcnew SolidBrush( Color::Red );

      // Create rectangle for ellipse.
      int x = 0;
      int y = 0;
      int width = 200;
      int height = 100;
      Rectangle rect = Rectangle(x,y,width,height);

      // Fill ellipse on screen.
      e->Graphics->FillEllipse( redBrush, rect );
   }
public void FillEllipseRectangle(PaintEventArgs e)
{
             
    // Create solid brush.
    SolidBrush redBrush = new SolidBrush(Color.Red);
             
    // Create rectangle for ellipse.
    int x = 0;
    int y = 0;
    int width = 200;
    int height = 100;
    Rectangle rect = new Rectangle(x, y, width, height);
             
    // Fill ellipse on screen.
    e.Graphics.FillEllipse(redBrush, rect);
}
Public Sub FillEllipseRectangle(ByVal e As PaintEventArgs)

    ' Create solid brush.
    Dim redBrush As New SolidBrush(Color.Red)
