Detailed Description
A rectangle is normally expressed as a top-left corner and a size. The size (width and height) of a Rect is always equivalent to the mathematical rectangle that forms the basis for its rendering.
A Rect can be constructed with a set of left, top, width and height integers, or from a Point and a Size.
There is a third constructor that creates a Rect using the top-left and bottom-right coordinates.
The Rect class provides a collection of functions that return the various rectangle coordinates, and enable manipulation of these. Rect also provides functions to move the rectangle relative to the various coordinates. In addition there is a moveTo() function that moves the rectangle, leaving its top left corner at the given coordinates. Alternatively, the translate() function moves the rectangle the given offset relative to the current position, and the translated() function returns a translated copy of this rectangle.
The size() function returns the rectangle's dimensions as a Size. The dimensions can also be retrieved separately using the width() and height() functions. To manipulate the dimensions use the setSize(), setWidth() or setHeight() functions. Alternatively, the size can be changed by applying either of the functions setting the rectangle coordinates, for example, setBottom() or setRight().
The contains() function tells whether a given point is inside the rectangle or not, and the intersects() function returns true if this rectangle intersects with a given rectangle. The Rect class also provides the intersected() function which returns the intersection rectangle, and the united() function which returns the rectangle that encloses the given rectangle and this:
The isEmpty() function returns true if left() > right() or top() > bottom(). Note that an empty rectangle is not valid: The isValid() function returns true if left() <= right() and top() <= bottom(). A null rectangle (isNull() == true) on the other hand, has both width and height set to 0.
Note that due to the way Rect and RectF are defined, an empty Rect is defined in essentially the same way as RectF.
Rect objects can be compared.
Coordinates
The Rect class provides a collection of functions that return the various rectangle coordinates, and enable manipulation of these. Rect also provides functions to move the rectangle relative to the various coordinates.
For example the left(), setLeft() and moveLeft() functions as an example: left() returns the x-coordinate of the rectangle's left edge, setLeft() sets the left edge of the rectangle to the given x coordinate (it may change the width, but will never change the rectangle's right edge) and moveLeft() moves the entire rectangle horizontally, leaving the rectangle's left edge at the given x coordinate and its size unchanged.
For compatibility with Qt, the values returned by the bottom() and right() functions deviate from the true bottom-right corner of the rectangle: The right() function returns left() + width() - 1 and the bottom() function returns top() + height() - 1. The same is the case for the point returned by the bottomRight() convenience function. In addition, the x and y coordinate of the topRight() and bottomLeft() functions, respectively, contain the same deviation from the true right and bottom edges.
We recommend that you use x() + width() and y() + height() to find the true bottom-right corner, and avoid right() and bottom(). Another solution is to use RectF: The RectF class defines a rectangle in the plane using floating point accuracy for coordinates, and the RectF::right() and RectF::bottom() functions do return the right and bottom coordinates.
It is also possible to add offsets to this rectangle's coordinates using the adjust() function, as well as retrieve a new rectangle based on adjustments of the original one using the adjusted() function. If either of the width and height is negative, use the normalized() function to retrieve a rectangle where the corners are swapped.
In addition, Rect provides the getCoords() function which extracts the position of the rectangle's top-left and bottom-right corner, and the getRect() function which extracts the rectangle's top-left corner, width and height. Use the setCoords() and setRect() function to manipulate the rectangle's coordinates and dimensions in one go.
Constraints
Rect is limited to the minimum and maximum values for the coord_t type. Operations on a Rect that could potentially result in values outside this range will result in undefined behavior.
See also RectF.

Note that for compatibility with Qt, this function returns Point(left() + width() -1, top() + height() - 1).
See also setBottomRight(), bottom(), and right().
Qul::PlatformInterface::Point Rect::center() const
Returns the center point of the rectangle.
See also moveCenter().
bool Rect::contains(const Qul::PlatformInterface::Rect &rectangle, bool proper = false) const
This is an overloaded function.
Returns true if the given rectangle is inside this rectangle. otherwise returns false. If proper is true, this function only returns true if the rectangle is entirely inside this rectangle (not on the edge).
bool Rect::contains(const Qul::PlatformInterface::Point &point, bool proper = false) const
This is an overloaded function.
Returns true if the given point is inside or on the edge of the rectangle, otherwise returns false. If proper is true, this function only returns true if the given point is inside the rectangle (i.e., not on the edge).
See also intersects().

bool Rect::intersects(const Qul::PlatformInterface::Rect &rectangle) const
Returns true if this rectangle intersects with the given rectangle (i.e., there is at least one pixel that is within both rectangles), otherwise returns false.
The intersection rectangle can be retrieved using the intersected() function.
See also contains().
bool Rect::isEmpty() const
Returns true if the rectangle is empty, otherwise returns false.
An empty rectangle has a left() > right() or top() > bottom(). An empty rectangle is not valid (i.e., isEmpty() == !isValid()).
Use the normalized() function to retrieve a rectangle where the corners are swapped.
See also isNull(), isValid(), and normalized().
bool Rect::isNull() const
Returns true if the rectangle is a null rectangle, otherwise returns false.
A null rectangle has both the width and the height set to 0 (i.e., right() == left() - 1 and bottom() == top() - 1). A null rectangle is also empty, and hence is not valid.
See also isEmpty() and isValid().
bool Rect::isValid() const
Returns true if the rectangle is valid, otherwise returns false.
A valid rectangle has a left() <= right() and top() <= bottom(). Note that non-trivial operations like intersections are not defined for invalid rectangles. A valid rectangle is not empty (i.e., isValid() == !isEmpty()).
See also isNull(), isEmpty(), and normalized().
