Beispiele

Im folgenden Codebeispiel wird ein ListBox Schatten hinzugefügt, indem die folgenden Member verwendet werden:

• Addition

• PointF.Addition

• SolidBrush

Dieses Beispiel ist für die Verwendung mit einem Windows-Formular konzipiert. Fügen Sie zum Ausführen dieses Beispiels diesen Code in ein Formular ein, und rufen Sie die AddShadow -Methode auf, wenn Sie das Ereignis des Formulars Paint behandeln. Stellen Sie sicher, dass das Formular einen ListBox namens listBox1enthält.

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

Hinweise

Die Einheit für eine SizeF Struktur hängt von den PageUnit Einstellungen und PageScale für das Graphics Objekt ab, das zum Zeichnen verwendet wird.
