RectF Class

A RectF object stores the upper-left corner, width, and height of a rectangle.

RectF has these types of members:

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.
Method Description
RectF::Clone The RectF::Clone method creates a new RectF object and initializes it with the contents of this RectF object.
RectF::Contains(PointF&) The RectF::Contains method determines whether a point is inside this rectangle.
RectF::Contains(REAL,REAL) The RectF::Contains method determines whether the point (x, y) is inside this rectangle.
RectF::Contains(RectF&) The RectF::Contains method determines whether another rectangle is inside this rectangle.
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(PointF&) 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(REAL,REAL) The RectF::Inflate method expands the rectangle by dx on the left and right edges, and by dy on the top and bottom edges.
RectF::Intersect(RectF&) The RectF::Intersect method replaces this rectangle with the intersection of itself and another rectangle.
RectF::Intersect(RectF&,RectF&,RectF&) 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(PointF&) The RectF::Offset method moves this rectangle horizontally a distance of point.X and vertically a distance of point.Y.
RectF::Offset(REAL,REAL) The RectF::Offset method moves the rectangle by dx horizontally and by dx vertically.
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.
