Examples

The following code example adds a shadow to a ListBox using a SolidBrush.

This example is designed to be used with a Windows Form. To run this example, paste this code into a form and call the AddShadow method when handling the form's Paint event. Make sure the form contains a ListBox named listBox1.

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
