RectF class (gdiplustypes.h)
A RectF object stores the upper-left corner, width, and height of a rectangle.
Constructors
The RectF class has these constructors.| Constructor | Description |
|---|---|
| RectF::RectF() | Creates a RectF object and initializes the X and Y data members to zero. This is the default constructor. |
| RectF::RectF(PointF&,SizeF&) | Creates a RectF object by using a PointF object to initialize the X and Y data members and uses a SizeF object to initialize the Width and Height data members of this rectangle. |
| RectF::RectF(REAL,REAL,REAL,REAL) | Creates a RectF object by using four integers to initialize the X, Y, Width, and Height data members. |
Methods
The RectF class has these methods.
| RectF::Clone The RectF::Clone method creates a new RectF object and initializes it with the contents of this RectF object. |
| RectF::Contains The RectF::Contains method determines whether a point is inside this rectangle. |
| RectF::Contains The RectF::Contains method determines whether another rectangle is inside this rectangle. |
| RectF::Contains This topic lists the Contains methods of the RectF class. For a complete list of methods for the RectF class, see RectF Methods. |
| RectF::Equals The RectF::Equals method determines whether two rectangles are the same. |
| RectF::GetBottom The RectF::GetBottom method gets the y-coordinate of the bottom edge of the rectangle. |
| RectF::GetBounds The RectF::GetBounds method makes a copy of this rectangle. |
| RectF::GetLeft The RectF::GetLeft method gets the x-coordinate of the left edge of the rectangle. |
| RectF::GetLocation The RectF::GetLocation method gets the coordinates of the upper-left corner of this rectangle. |
| RectF::GetRight The RectF::GetRight method gets the x-coordinate of the right edge of the rectangle. |
| RectF::GetSize The RectF::GetSize method gets the width and height of this rectangle. |
| RectF::GetTop The RectF::GetTop method gets the y-coordinate of the top edge of the rectangle. |
| RectF::Inflate The RectF::Inflate method expands the rectangle by the value of point.X on the left and right edges, and by the value of point.Y on the top and bottom edges. |
| RectF::Inflate This topic lists the Inflate methods of the RectF class. For a complete list of methods for the RectF class, see RectF Methods. |
| RectF::Intersect This topic lists the Intersect methods of the RectF class. For a complete list of methods for the RectF class, see RectF Methods. |
| RectF::Intersect The RectF::Intersect method determines the intersection of two rectangles and stores the result in a RectF object. |
| RectF::IntersectsWith The RectF::IntersectsWith method determines whether this rectangle intersects another rectangle. |
| RectF::IsEmptyArea The RectF::IsEmptyArea method determines whether this rectangle is empty. |
| RectF::Offset This topic lists the Offset methods of the RectF class. For a complete list of methods for the RectF class, see Rect Methods. |
| RectF::Offset The RectF::Offset method moves the rectangle by dx horizontally and by dx vertically. |
| RectF::RectF Creates a RectF object and initializes the X, Y, Width, and Height data members to zero. This is the default constructor. (RectF.RectF) |
| RectF::RectF Creates a RectF object and initializes the X, Y, Width, and Height data members to zero. This is the default constructor. (overload 1/2) |
| RectF::RectF Creates a RectF object by using four integers to initialize the X, Y, Width, and Height data members. |
| RectF::Union The RectF::Union method determines the union of two rectangles and stores the result in a RectF object. |
Remarks
The upper-left corner of the rectangle is located at ( x, y). The size of the rectangle is measured by width and height. There are methods for high-level functionality, such as moving, resizing, and performing or testing interactions with other rectangles.
