Contoh

• Contoh kode berikut menambahkan bayangan ke ListBox menggunakan Addition operator . Contoh ini dirancang untuk digunakan dengan Formulir Windows. Untuk menjalankan contoh ini, tempelkan kode ini ke dalam formulir dan panggil AddShadow metode saat menangani peristiwa formulir Paint . Pastikan formulir berisi bernama ListBoxlistBox1.

private:
   void AddShadow( PaintEventArgs^ e )
   {
      // Create two SizeF objects.
      SizeF shadowSize = listBox1->Size;
      SizeF addSize = SizeF(10.5F,20.8F);

      // Add them together and save the result in shadowSize.
      shadowSize = shadowSize + addSize;

      // Get the location of the ListBox and convert it to a PointF.
      PointF shadowLocation = listBox1->Location;

      // Add two points to get a new location.
      shadowLocation = shadowLocation + System::Drawing::Size( 5, 5 );

      // Create a rectangleF. 
      RectangleF rectFToFill = RectangleF(shadowLocation,shadowSize);

      // Create a custom brush using a semi-transparent color, and 
      // then fill in the rectangle.
      Color customColor = Color::FromArgb( 50, Color::Gray );
      SolidBrush^ shadowBrush = gcnew SolidBrush( customColor );
      array<RectangleF>^ temp0 = {rectFToFill};
      e->Graphics->FillRectangles( shadowBrush, temp0 );

      // Dispose of the brush.
      delete shadowBrush;
   }

private void AddShadow(PaintEventArgs e)
{

    // Create two SizeF objects.
    SizeF shadowSize = listBox1.Size;
    SizeF addSize = new SizeF(10.5F, 20.8F);

    // Add them together and save the result in shadowSize.
    shadowSize = shadowSize + addSize;

    // Get the location of the ListBox and convert it to a PointF.
    PointF shadowLocation = listBox1.Location;

    // Add two points to get a new location.
    shadowLocation = shadowLocation + new Size(5, 5);

    // Create a rectangleF. 
    RectangleF rectFToFill = 
        new RectangleF(shadowLocation, shadowSize);

    // Create a custom brush using a semi-transparent color, and 
    // then fill in the rectangle.
    Color customColor = Color.FromArgb(50, Color.Gray);
    SolidBrush shadowBrush = new SolidBrush(customColor);
    e.Graphics.FillRectangles(shadowBrush, new RectangleF[]{rectFToFill});

    // Dispose of the brush.
    shadowBrush.Dispose();
}

Private Sub AddShadow(ByVal e As PaintEventArgs)

    ' Create two SizeF objects.
    Dim shadowSize As SizeF = Size.op_Implicit(listBox1.Size)
    Dim addSize As New SizeF(10.5F, 20.8F)

    ' Add them together and save the result in shadowSize.
    shadowSize = SizeF.op_Addition(shadowSize, addSize)

    ' Get the location of the ListBox and convert it to a PointF.
    Dim shadowLocation As PointF = Point.op_Implicit(listBox1.Location)

    ' Add a Size to the Point to get a new location.
    shadowLocation = PointF.op_Addition(shadowLocation, New Size(5, 5))

    ' Create a rectangleF. 
    Dim rectFToFill As New RectangleF(shadowLocation, shadowSize)

    ' Create a custom brush using a semi-transparent color, and 
    ' then fill in the rectangle.
    Dim customColor As Color = Color.FromArgb(50, Color.Gray)
    Dim shadowBrush As SolidBrush = New SolidBrush(customColor)
    e.Graphics.FillRectangles(shadowBrush, _
        New RectangleF() {rectFToFill})

    ' Dispose of the brush.
    shadowBrush.Dispose()
End Sub

Addition(PointF, SizeF)

Sumber:

PointF.cs

Menerjemahkan PointF oleh yang ditentukan SizeF.

public:
 static System::Drawing::PointF operator +(System::Drawing::PointF pt, System::Drawing::SizeF sz);

public static System.Drawing.PointF operator + (System.Drawing.PointF pt, System.Drawing.SizeF sz);

static member ( + ) : System.Drawing.PointF * System.Drawing.SizeF -> System.Drawing.PointF

Public Shared Operator + (pt As PointF, sz As SizeF) As PointF

Parameter

pt

PointF

yang akan diterjemahkan PointF .

sz

SizeF

SizeF yang menentukan angka yang akan ditambahkan ke koordinat x- dan y dari PointF.

Mengembalikan

PointF

Yang diterjemahkan PointF.

Contoh

Contoh kode berikut menunjukkan cara menggunakan Addition operator. Untuk menjalankan contoh ini, tempelkan kode berikut ke dalam Formulir Windows. Tangani peristiwa formulir Paint dan panggil opAdditionExample, meneruskan e sebagai PaintEventArgs.

private void OpAdditionExample(PaintEventArgs e)
{
    PointF point1 = new PointF(120.5F, 120F);
    SizeF size1 = new SizeF(120.5F, 30.5F);
    RectangleF rect1 = new RectangleF(point1, size1);
    if (new PointF(rect1.Right, rect1.Bottom) == point1 + size1)
        e.Graphics.DrawString("They are equal", this.Font, Brushes.Black, rect1);
    else
        e.Graphics.DrawString("They are not equal", this.Font, Brushes.Red, rect1);
}

Private Sub OpAdditionExample(ByVal e As PaintEventArgs) 
    Dim size1 As New SizeF(120.5F, 30.5F)
    Dim point1 As New PointF(20.5F, 20F)
    Dim rect1 As New RectangleF(point1, size1)
    If New PointF(rect1.Right, rect1.Bottom) = point1 + size1 Then
        e.Graphics.DrawString("They are equal", Me.Font, Brushes.Black, rect1)
    Else
        e.Graphics.DrawString("They are not equal", Me.Font, Brushes.Red, rect1)
    End If
 
End Sub

Keterangan

Operator Addition menambahkan Width ukuran yang ditentukan ke koordinat PointF x dan Height ke koordinat y dari PointF.

Metode yang setara untuk operator ini adalah PointF.Add(PointF, SizeF)
