public value struct 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)

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_staticExplicit(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:
   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;
   }
