Public Structure SizeF

NameDescription
System_CAPS_pubmethodSizeF(PointF)

Initializes a new instance of the SizeF structure from the specified PointF structure.

System_CAPS_pubmethodSizeF(Single, Single)

Initializes a new instance of the SizeF structure from the specified dimensions.

System_CAPS_pubmethodSizeF(SizeF)

Initializes a new instance of the SizeF structure from the specified existing SizeF structure.

NameDescription
System_CAPS_pubpropertyHeight

Gets or sets the vertical component of this SizeF structure.

System_CAPS_pubpropertyIsEmpty

Gets a value that indicates whether this SizeF structure has zero width and height.

System_CAPS_pubpropertyWidth

Gets or sets the horizontal component of this SizeF structure.

NameDescription
System_CAPS_pubmethodSystem_CAPS_staticAdd(SizeF, SizeF)

Adds the width and height of one SizeF structure to the width and height of another SizeF structure.

System_CAPS_pubmethodEquals(Object)

Tests to see whether the specified object is a SizeF structure with the same dimensions as this SizeF structure.(Overrides ValueType.Equals(Object).)

System_CAPS_pubmethodGetHashCode()

Returns a hash code for this Size structure.(Overrides ValueType.GetHashCode().)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethodSystem_CAPS_staticSubtract(SizeF, SizeF)

Subtracts the width and height of one SizeF structure from the width and height of another SizeF structure.

System_CAPS_pubmethodToPointF()

Converts a SizeF structure to a PointF structure.

System_CAPS_pubmethodToSize()

Converts a SizeF structure to a Size structure.

System_CAPS_pubmethodToString()

Creates a human-readable string that represents this SizeF structure.(Overrides ValueType.ToString().)

NameDescription
System_CAPS_pubfieldSystem_CAPS_staticEmpty

Gets a SizeF structure that has a Height and Width value of 0.

NameDescription
System_CAPS_puboperatorSystem_CAPS_staticAddition(SizeF, SizeF)

Adds the width and height of one SizeF structure to the width and height of another SizeF structure.

System_CAPS_puboperatorSystem_CAPS_staticEquality(SizeF, SizeF)

Tests whether two SizeF structures are equal.

System_CAPS_puboperatorSystem_CAPS_staticNarrowing(SizeF to PointF)

Converts the specified SizeF structure to a PointF structure.

System_CAPS_puboperatorSystem_CAPS_staticInequality(SizeF, SizeF)

Tests whether two SizeF structures are different.

System_CAPS_puboperatorSystem_CAPS_staticSubtraction(SizeF, SizeF)

Subtracts the width and height of one SizeF structure from the width and height of another SizeF structure.

The unit for a SizeF structure depends on the PageUnit and PageScale settings for the Graphics object that is used to draw.

The following code example adds a shadow to a ListBox by using the following members:

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. Verify that the form contains a ListBox named listBox1.

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
