Example

MyPoint is Point
MyPoint..X = 280
MyPoint..Y = 54

Syntax

Declaring and initializing a point Hide the details

<Point name> is Point

<Point name>:

Name of the Point variable to declare.

Remarks

WLanguage properties that can be used with the Point type

The initial value of a point is set to (0,0).

The following properties can be used to handle a Point variable:

Property name	Effect

X	X coordinate of the point. This coordinate corresponds to a signed 4-byte integer.
Y	Y coordinate of the point. This coordinate corresponds to a signed 4-byte integer.

Assigning a Point variable

A Point variable can be assigned with:

another point.
For example:

MyPoint is Point
MyPoint..X = 280
MyPoint..Y = 54
MyPoint1 is Point = MyPoint
an array of two values that can be converted into integer.
For example:

MyPoint is Point
MyPoint = [280, 54]

Assigning an array of Points

An array of Points can be assigned with:

an array of values containing points.
For example:

ArrayOfPoints is array of Points
ArrayOfPoints = [MyPoint1,MyPoint2]
an array of two values that can be converted into integer.
For example:

ArrayOfPoints is array of Points
ArrayOfPoints = [[1,2],[3,4]]

Comparison and serialization

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

Notes

A Point variable can be stored in a variant.
A Point variable is never null:
- The "PointVariable = NULL" condition always returns False.
- The "PointVariable <> NULL" condition always returns True.
You cannot reference a Point variable.
The "PointVariable2 <- PointVariable1" syntax triggers an error.
You cannot force the copy of a Point variable.
The "PointVariable2 <= PointVariable1" syntax triggers an error.
You have the ability to add and subtract two Point variables.
The Point variables can be passed to the system APIs.
