TUIRectangle Record

A platform independent rectangle. Coordinates are floating point numbers.

Syntax

TUIRectangle = record;

Name	Description
Create	Creates a new UIRectangle with the specified starting point, height and width.
FromLTRB	Creates a new rectangle with the specified coordinates.
Inflate	Overloaded Inflate(Double, Double) Inflate(TUIRectangle, Double, Double)
Offset	Moves the rectangle by (dx, dy), keeping the with and height the same.
Union	Returns a new rectangle which contains both of the source rectangles.
MakePositive	This method ensures both width adn height are positive. If they are negative, X and Y are moved so the rectangle is the same but with positive dimensions.
Contains	Returns true if point is inside the rectangle.
FullyInside	Returns true if this rectangle is fully inside other.
FullyOutside	Returns true if this rectangle is fully outside other.
ToString	Returns a string with the rectangle's data.
Intersect	Returns a rectangle which is the intersection of this one and the new one.

Name	Description
Equality	Adapts the = operator so it returns true when both instances have the same values.
Inequality	Adapts the <> operator so it returns true when both instances have different values.

Name	Description
Empty	Returns a rectangle with X = 0, Y = 0, Width = 0 and Height = 0.
Location	Returns a TPointF with the Left and Top coordinates of the rectangle.
BottomRight	Returns a TPointF with the Right and Bottom coordinates of the rectangle.
X	Left coordinate of the rectangle.
Y	Top coordinate of the rectangle.
Width	Width of the rectangle.
Height	Height of the rectangle.
Top	Top coordinate. This is the same as Y, but it is readonly. (Y is read write).
Left	Left coordinate. This is the same as X, but it is readonly. (X is read write).
Right	Right coordinate.
Bottom	Bottom coordinate.
