Examples
- The following code example adds a shadow to a ListBox using the Addition operator. 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 namedlistBox1
.
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

Examples
The following code example demonstrates how to use the Addition operator. To run this example, paste the following code into a Windows Form. Handle the form's Paint event and call opAdditionExample
, passing e
as 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
Remarks
The Addition operator adds the Width of the specified size to the x-coordinate of the PointF and the Height to the y-coordinate of the PointF.
The equivalent method for this operator is PointF.Add(PointF, SizeF)
