Rectangle (Type of variable)
In french: Rectangle
A Rectangle variable is a structured type that is used to represent a rectangle (X, Y, Width, Height) in 2 dimensions.
Example
MyRectangle is Rectangle
MyRectangle..X = 280
MyRectangle..Y = 54
MyRectangle..Width = 50
MyRectangle..Height = 150
Syntax

Declaring and initializing a rectangle Hide the details

<Rectangle Name> is Rectangle
<Rectangle Name>:
Name of the Rectangle variable to declare.
Remarks

WLanguage properties that can be used with the Rectangle type

The initial value of a rectangle is set to (0,0,0,0).
The following properties can be used to handle a Rectangle variable:
Property nameEffect
HeightHeight of the rectangle. This coordinate corresponds to a signed 4-byte integer.
WidthWidth of the rectangle. This coordinate corresponds to a signed 4-byte integer.
XX coordinate of the top left point. This coordinate corresponds to a signed 4-byte integer.
YY coordinate of the top left point. This coordinate corresponds to a signed 4-byte integer.

Assigning a Rectangle variable

A Rectangle variable can be assigned with:
  • another Rectangle variable.
    For example:
    MyRectangle is Rectangle
    MyRectangle..X = 280
    MyRectangle..Y = 54
    MyRectangle..Width = 50
    MyRectangle..Height = 150
    MyRectangle1 is Rectangle = MyRectangle
  • an array of four values that can be converted into integer.
    For example:
    MyRectangle is Rectangle
    MyRectangle = [280, 54, 50, 150]
  • two Point variables (corresponding respectively to the top left corner and to the bottom right corner of the rectangle).
    For example:
    MyRectangle is Rectangle
    MyRectangle = [[280, 54], [330, 204]]

Assigning an array of Rectangles

An array of rectangles can be assigned with:
  • an array of values containing rectangles.
    For example:
    ArrayOfRectangles is array of Rectangles
    ArrayOfRectangles = [MyRectangle1, MyRectangle2]
  • an array of four values that can be converted into integer.
    For example:
    ArrayOfRectangles is array of Rectangles
    ArrayOfRectangles = [[1,2,3,4], [5,6,7,8]

Comparison and serialization

  • Comparison: The comparison operators = and <> are available.
  • Serialization: The binary, XML and JSON serializations are available.
    Caution: During an XML serialization, the xmlAttribute constant cannot be used on a Rectangle class member or on a Rectangle structure member.

Notes

  • A Rectangle variable can be stored in a variant.
  • A Rectangle variable is never null:
    • The "RectangleVariable = NULL" condition always returns False.
    • The "RectangleVariable <> NULL" condition always returns True.
  • You cannot reference a Rectangle variable.
    The "RectangleVariable2 <- RectangleVariable1" syntax triggers an error.
  • You cannot force the copy of a Rectangle variable.
    The "RectangleVariable2 <= RectangleVariable1" syntax triggers an error.
  • You have the ability to add a Point variable and a Rectangle variable. This operation is used to perform a relocation of the rectangle.
  • You have the ability to subtract a Point variable to a Rectangle variable. This operation is used to perform a relocation of the rectangle.
  • The Rectangle variables can be passed to the system APIs.
Minimum version required
  • Version 21
