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.
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 name | Effect |
|---|
| Height | Height of the rectangle. This coordinate corresponds to a signed 4-byte integer. | | Width | Width of the rectangle. This coordinate corresponds to a signed 4-byte integer. | | X | X-coordinate of the top left point. This coordinate corresponds to a signed 4-byte integer. | | Y | Y-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 upper-left corner and to the lower-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.
